I have two methods:
1:
#Transactional
public Long add(Long clientId) {
Contact contact = new Contact();
contact.setClientId(clientId);
contact.setValue('test#test.com');
contact.setType('EMAIL');
contact.setDateStart(new Date());
// autowired repo
return contactRepository.saveAndFlush(contact);
}
2:
#Transactional(propagation = Propagation.NOT_SUPPORTED)
public void emailsValidator(Long clientId) {
Specification<Client> spec = ClientSearchSpecification.getByClientIdWithActiveEmails(clientId);
List<Client> clientList = clientRepository.findAll(spec);
}
SearchSpecification:
public static Specification<Client> getByClientIdWithActiveEmails(Long clientId) {
return (root, query, cb) -> {
query.distinct(true);
Join<Client, Contact> clientContactJoin = (Join) root.fetch(Client_.contactList);
List<Predicate> predicates = new ArrayList<>();
predicates.add(cb.equal(root.get(AbstractEntity_.id), clientId));
predicates.add(cb.equal(clientContaktJoin.get(Contakt_.type), 'EMAIL'));
predicates.add(cb.lessThan(clientContaktJoin.get(Contakt_.dateStart), cb.currentTimestamp()));
return cb.and(predicates.toArray(new Predicate[predicates.size()]));
};
}
Main method:
#RequestMapping(value = "/{clientId}/contact/add", method = RequestMethod.POST, produces = "application/json; charset=UTF-8")
public void addContact(#PathVariable(value = "clientId") Long clientId) {
contactService.add(clientId);
errorValidationService.emailsValidator(clientId);
}
My db properties:
hibernate.transaction.auto_close_session: true
hibernate.connection.autocommit: true
org.hibernate.flushMode: COMMIT
The problem - DB doesn't contain new entity from step 1 while executing step 2. The object is commited only after all rest call finishes. How do I commit entity on step 1 so that I can select and join it in step 2?
You don't need to be committed to select your data (within the same transaction).
The problem here is that you've said step 2 needs to be `NOT_SUPPORTED, which implies that step 1 must commit before step 2 can see any of the data it inserted.
Try changing the propagation of step 1 to REQUIRES_NEW to ensure the commit occurs before you get to step 2.
It turned out that I was using two different #Transaction implementations in repository interface:
#Transactional
public interface ClientRepository extends JpaRepository<Client, Long>, JpaSpecificationExecutor<Client>
I used:
import javax.transaction.Transactional;
I should've use:
import org.springframework.transaction.annotation.Transactional;
Which meant that settings for spring #Transaction were not applied and it couldn't commit itself at the end of the method, It did commits only at the end of the call.

First - I've checked all previous topics around this question and none of them helped.
Having the following code:
#DisplayName("GET RecipeUltraLight by id is successful")
#Test
public void givenRecipeId_whenGetRecipeDetailsById_thenReturnRecipeObject(){
// given
given(this.recipeRepository.findById(recipe.getId())).willReturn(Optional.of(recipe));
given(this.recipeService.getRecipeById(recipe.getId())).willReturn(recipe);
given(this.recipeConverter.toUltraLight(recipe)).willReturn(recipeUltraLightDto);
// when
RecipeUltraLightDto retrievedRecipe = recipeService.getRecipeUltraLightById(recipe.getId());
// then
verify(recipeRepository, times(1)).findById(recipe.getId());
verify(recipeService, times(1)).getRecipeById(recipe.getId());
verify(recipeConverter, times(1)).toUltraLight(recipe);
assertThat(retrievedRecipe).isNotNull();
}
gives me this error:
org.mockito.exceptions.misusing.WrongTypeOfReturnValue:
Recipe cannot be returned by findById()
findById() should return Optional
***
If you're unsure why you're getting above error read on.
Due to the nature of the syntax above problem might occur because:
1. This exception *might* occur in wrongly written multi-threaded tests.
Please refer to Mockito FAQ on limitations of concurrency testing.
2. A spy is stubbed using when(spy.foo()).then() syntax. It is safer to stub spies -
- with doReturn|Throw() family of methods. More in javadocs for Mockito.spy() method.
Service method:
#Transactional(readOnly = true)
public RecipeUltraLightDto getRecipeUltraLightById(Long id) {
Recipe recipe = getRecipeById(id);
RecipeUltraLightDto dto = new RecipeUltraLightDto();
dto = recipeConverter.toUltraLight(recipe);
return dto;
}
// internal use only
#Transactional(readOnly = true)
public Recipe getRecipeById(Long id) {
if (id == null || id < 1) {
return null;
}
return recipeRepository.findById(id)
.orElseThrow(() -> new RecipeNotFoundException(
String.format("Recipe with id %d not found.", id)
));
}
Setup:
#ContextConfiguration(classes = {RecipeService.class})
#ExtendWith({SpringExtension.class, MockitoExtension.class})
class RecipeServiceTest {
#MockBean
private RecipeConverter recipeConverter;
#MockBean
private RecipeRepository recipeRepository;
#Autowired
private RecipeService recipeService;
private Recipe recipe;
private RecipeUltraLightDto recipeUltraLightDto;
#BeforeEach
public void setup(){
recipe = Recipe.builder()
.id(1L)
.name("Recipe")
.description("Description")
.createdAt(LocalDateTime.now())
.difficulty(RecipeDifficulty.EASY)
.minutesRequired(60)
.portions(4)
.authorId(1L)
.views(0)
.isVerified(false)
.build();
recipeUltraLightDto = RecipeUltraLightDto.builder()
.id(1L)
.name("Recipe")
.build();
}
I've tried:
Optinal.ofNullable()
Adding .isPresent()
Getting rid of .orElseThrow and going through if statements and using .get()
Kotlin
Will be glad if someone can help.
You are creating a mock of the object you are testing and with that basically also render the mocking of the repository useless.
You should remove the line given(this.recipeService.getRecipeById(recipe.getId())).willReturn(recipe); that way it will just call the method and call the repository. Which now will return the mocked result. As that is the behavior that will now kick in.
It is clearly mentioned that the method findById() returning Optional, you need to get Recipe by invoking Optional.get().
I have two transaction manager for two database. I need to persist same data into both databases. If one transaction failed, other one need rollback. I have done like below
public interface DataService {
void saveData();
}
#Service
public class DataServiceImpl implements DataService {
#Autowired
private DataRepository dataRepository;
#Autowired
private OrDataRepository orDataRepository;
#Autowired
#Qualifier("orService")
private OrService orDataServiceImpl;
#Override
#Transactional(transactionManager = "transactionManager", rollbackFor = {RuntimeException.class})
public void saveData() {
Data data = new Data();
data.setCompKey(UUID.randomUUID().toString().substring(1,5));
data.setName("data");
dataRepository.save(data);
orDataServiceImpl.save();
//throw new RuntimeException("");
}
}
public interface OrService {
void save();
}
#Service("orService")
public class OrDataServiceImpl implements OrService {
#Autowired
private OrDataRepository orDataRepository;
#Override
#Transactional(rollbackFor = {RuntimeException.class})
public void save() {
OrData data = new OrData();
data.setCompKey(UUID.randomUUID().toString().substring(1,5));
data.setName("ordata");
orDataRepository.save(data);
}
}
I have two transaction manager (entityManager & orEntityManager) for two different DB.
If any exception in OrDataServiceImpl save method, data is not getting persisted in both DB. But if any exception in DataServiceImpl saveData method, data is getting persisted into OrData table.
I want to rollback the data from both DB if any exception.
chainedTransactionManager is deprecated. So can't use. atomikos and bitronix also can't use due to some restrictions. Kindly suggest better way to achieve distributed transation
The code need to be refactored, edit the DataServiceImpl.save() method.
Comment the orDataServiceImpl.save() line
public void saveData() {
Data data = new Data();
data.setCompKey(UUID.randomUUID().toString().substring(1,5));
data.setName("data");
dataRepository.save(data);
//orDataServiceImpl.save();
//throw new RuntimeException("");
}
Refactor/Edit the OrDataService Interface
public interface OrDataService {
void save(String uuid);
void delete(String uuid);
//will be use for compensating transaction
}
Update the OrDataServiceImpl class to implement above interface
Write new orchestration Method and use compensating transaction to rollback
pseudo code
call OrDataServiceImpl.save()
if step#1 was success
-> DataServiceImpl.saveData()
if Exception at step#3,
->OrDataServiceImpl.delete() [//to rollback]
else if, Exception at step#1
//do nothing
Written a short convenicence extension for Testcontainers:
fun JdbcDatabaseContainer<*>.execute(query:DSLContext.()-> Query){
val connection = DriverManager.getConnection(this.getJdbcUrl(),this.getUsername(),this.getPassword())
val create = DSL.using(connection)
create.query().execute()
}
And now wanted to test it.
Flyway loads 30 entries. These should be visible in allDataPresent
canInsert inserts one entry without the extension
canInsertWithExtension does the same but via the extension function
insertMultipleWithExtension does exactly as its name implies and inserts another 5
All but the allDataPresent testcase (because that one is read-only anyway) are annotated #Transactional.
As such, I'd expect these modifications to be rolled back after the test method.
What instead happens is
[ERROR] Failures:
[ERROR] InitDataIT.allDataPresent:70
Expecting:
<36>
to be equal to:
<30>
but was not.
[ERROR] InitDataIT.canInsert:90
Expecting:
<6>
to be equal to:
<1>
but was not.
[ERROR] InitDataIT.canInsertWithExtension:112
Expecting:
<6>
to be equal to:
<1>
but was not.
Each #Test is working fine on its own. So the issue must lie with the #Transactional.
So why is that? And more importantly, how do I get the rollbacks?

The Spring #Transactional annotation doesn't just magically work with your DriverManager created JDBC connections. Your dbContainer object should operate on your spring managed data source instead.
I have a category -> subCategory -> products hierarchy in my application. If a subcategory has no products, you are allowed to delete it. If a subCategory has products, the DAO throws a DataIntegrityViolationException and the transaction should be rolled back.
In my tests, I have:
#RunWith(SpringJUnit4ClassRunner.class)
#ContextConfiguration(classes = {TestTransactionManagement.class})
public class BusinessSubCategoryCRUDTest {
#Autowired
public void setCRUD(BusinessSubCategoryCRUD crud) {
this.crud = crud;
}
// #Transactional
#Test
public void testDeleteBusinessSubCategoryInUseCanNotBeDeleted() {
final long id = 1;
BusinessSubCategory subCategoryBeforeDelete =
crud.readBusinessSubCategory(id);
final int numCategoriesBeforeDelete =
subCategoryBeforeDelete.getBusinessCategories().size();
try {
crud.deleteBusinessSubCategory(
new BusinessSubCategory(id, ""));
} catch (DataIntegrityViolationException e) {
System.err.println(e);
}
BusinessSubCategory subCategoryAfterDeleteFails =
crud.readBusinessSubCategory(id);
// THIS next assertion is the source of my angst.
// At this point the the links to the categories will have been
// been deleted, an exception will have been thrown but the
// Transaction is not yet rolled back if the test case (or test
// class) is marked with #Transactional
assertEquals(
numCategoriesBeforeDelete,
subCategoryAfterDeleteFails.getBusinessCategories().size());
}
}
However, if I uncomment the #Transactional above #Test, it fails. I think the DAO is using the transaction from the #Test and so the transaction doesn't roll back until AFTER I check to be sure the transaction has been rolled back.
#Transactional(readOnly = false, propagation =
Propagation.REQUIRED)
public boolean deleteBusinessSubCategory(
BusinessSubCategory businessSubCategory) {
BeanPropertySqlParameterSource paramMap = new
BeanPropertySqlParameterSource(businessSubCategory);
namedJdbcTemplate.update(
DELETE_CATEGORY_SUB_CATEGORY_BY_ID_SQL,
paramMap);
return 0 != namedJdbcTemplate.update(
DELETE_SUB_CATEGORY_BY_ID_SQL,
paramMap);
}
So, how do I have the DAO code still inherit the transaction from the context it is running in (in production it inherits the transaction from the service it is running in) but still be able to test it. I want to put #Transactional on the entire test class, but that then leaves my test either failing or incomplete.
For completeness, here is my configuration class for the test.
#Configuration
#EnableTransactionManagement
public class TestTransactionManagement {
#Bean
public EmbeddedDatabase getDataSource() {
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
EmbeddedDatabase db = builder
.setType(EmbeddedDatabaseType.HSQL) //.H2 or .DERBY
.addScript("sql/create-db.sql")
.addScript("sql/create-test-data.sql")
.build();
return db;
}
#Bean
public DataSourceTransactionManager transactionManager() {
return new DataSourceTransactionManager(getDataSource());
}
#Bean
public BusinessSubCategoryCRUD getCRUD() {
return new BusinessSubCategoryCRUD(getDataSource());
}
}
The "solution" or workaround was to reset the database before each test. Then there was no need for an #Transactional on the test, the rollback could be tested, and the test suite ran slighly slower due to the additional database setup.
#Before
public void setUp() {
Connection conn = DataSourceUtils.getConnection(dataSource);
ScriptUtils.executeSqlScript(
conn, new ClassPathResource("sql/create-test-data.sql"));
DataSourceUtils.releaseConnection(conn, dataSource);
}
I am working with Spring and EhCache
I have the following method
#Override
#Cacheable(value="products", key="#root.target.PRODUCTS")
public Set<Product> findAll() {
return new LinkedHashSet<>(this.productRepository.findAll());
}
I have other methods working with #Cacheable and #CachePut and #CacheEvict.
Now, imagine the database returns 100 products and they are cached through key="#root.target.PRODUCTS", then other method would insert - update - deleted an item into the database. Therefore the products cached through the key="#root.target.PRODUCTS" are not the same anymore such as the database.
I mean, check the two following two methods, they are able to update/delete an item, and that same item is cached in the other key="#root.target.PRODUCTS"
#Override
#CachePut(value="products", key="#product.id")
public Product update(Product product) {
return this.productRepository.save(product);
}
#Override
#CacheEvict(value="products", key="#id")
public void delete(Integer id) {
this.productRepository.delete(id);
}
I want to know if is possible update/delete the item located in the cache through the key="#root.target.PRODUCTS", it would be 100 with the Product updated or 499 if the Product was deleted.
My point is, I want avoid the following:
#Override
#CachePut(value="products", key="#product.id")
#CacheEvict(value="products", key="#root.target.PRODUCTS")
public Product update(Product product) {
return this.productRepository.save(product);
}
#Override
#Caching(evict={
#CacheEvict(value="products", key="#id"),
#CacheEvict(value="products", key="#root.target.PRODUCTS")
})
public void delete(Integer id) {
this.productRepository.delete(id);
}
I don't want call again the 500 or 499 products to be cached into the key="#root.target.PRODUCTS"
Is possible do this? How?
Thanks in advance.
Caching the collection using the caching abstraction is a duplicate of what the underlying caching system is doing. And because this is a duplicate, it turns out that you have to resort to some kind of duplications in your own code in one way or the other (the duplicate key for the set is the obvious representation of that). And because there is duplication, you have to sync state somehow
If you really need to access to the whole set and individual elements, then you should probably use a shortcut for the easiest leg. First, you should make sure your cache contains all elements which is not something that is obvious. Far from it actually. Considering you have that:
//EhCacheCache cache = (EhCacheCache) cacheManager.getCache("products");
#Override
public Set<Product> findAll() {
Ehcache nativeCache = cache.getNativeCache();
Map<Object, Element> elements = nativeCache.getAll(nativeCache.getKeys());
Set<Product> result = new HashSet<Product>();
for (Element element : elements.values()) {
result.add((Product) element.getObjectValue());
}
return Collections.unmodifiableSet(result);
}
The elements result is actually a lazy loaded map so a call to values() may throw an exception. You may want to loop over the keys or something.
You have to remember that the caching abstraction eases the access to the underlying caching infrastructure and in no way it replaces it: if you had to use the API directly, this is probably what you would have to do in some sort.
Now, we can keep the conversion on SPR-12036 if you believe we can improve the caching abstraction in that area. Thanks!
I think something like this schould work... Actually it's only a variation if "Stéphane Nicoll" answer ofcourse, but it may be useful for someone. I write it right here and haven't check it in IDE, but something similar works in my Project.
Override CacheResolver:
#Cacheable(value="products", key="#root.target.PRODUCTS", cacheResolver = "customCacheResolver")
Implement your own cache resolver, which search "inside" you cached items and do the work in there
public class CustomCacheResolver implements CacheResolver{
private static final String CACHE_NAME = "products";
#Autowired(required = true) private CacheManager cacheManager;
#SuppressWarnings("unchecked")
#Override
public Collection<? extends Cache> resolveCaches(CacheOperationInvocationContext<?> cacheOperationInvocationContext) {
// 1. Take key from query and create new simple key
SimpleKey newKey;
if (cacheOperationInvocationContext.getArgs().length != null) { //optional
newKey = new SimpleKey(args); //It's the key of cached object, which your "#Cachable" search for
} else {
//Schould never be... DEFAULT work with cache if something wrong with arguments
return new ArrayList<>(Arrays.asList(cacheManager.getCache(CACHE_NAME)));
}
// 2. Take cache
EhCacheCache ehCache = (EhCacheCache)cacheManager.getCache(CACHE_NAME); //this one we bringing back
Ehcache cache = (Ehcache)ehCache.getNativeCache(); //and with this we working
// 3. Modify existing Cache if we have it
if (cache.getKeys().contains(newKey) && YouWantToModifyIt) {
Element element = cache.get(key);
if (element != null && !((List<Products>)element.getObjectValue()).isEmpty()) {
List<Products> productsList = (List<Products>)element.getObjectValue();
// ---**--- Modify your "productsList" here as you want. You may now Change single element in this list.
ehCache.put(key, anfragenList); //this method NOT adds cache, but OVERWRITE existing
// 4. Maybe "Create" new cache with this key if we don't have it
} else {
ehCache.put(newKey, YOUR_ELEMENTS);
}
return new ArrayList<>(Arrays.asList(ehCache)); //Bring all back - our "new" or "modified" cache is in there now...
}

Hope it helps. And sorry for my English:(
I think there is a way to read the collection from underlying cache structure of spring. You can retrieve the collection from underlying ConcurrentHashMap as key-value pairs without using EhCache or anything else. Then you can update or remove an entry from that collection and then you can update the cache too. Here is an example that may help:
import com.crud.model.Post;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.Cache;
import org.springframework.cache.CacheManager;
import org.springframework.cache.interceptor.CacheOperationInvocationContext;
import org.springframework.cache.interceptor.CacheResolver;
import org.springframework.cache.interceptor.SimpleKey;
import org.springframework.stereotype.Component;
import java.util.*;
#Component
#Slf4j
public class CustomCacheResolver implements CacheResolver {
private static final String CACHE_NAME = "allPost";
#Autowired
private CacheManager cacheManager;
#SuppressWarnings("unchecked")
#Override
public Collection<? extends Cache> resolveCaches(CacheOperationInvocationContext<?> cacheOperationInvocationContext) {
log.info(Arrays.toString(cacheOperationInvocationContext.getArgs()));
String method = cacheOperationInvocationContext.getMethod().toString();
Post post = null;
Long postId = null;
if(method.contains("update")) {
//get the updated post
Object[] args = cacheOperationInvocationContext.getArgs();
post = (Post) args[0];
}
else if(method.contains("delete")){
//get the post Id to delete
Object[] args = cacheOperationInvocationContext.getArgs();
postId = (Long) args[0];
}
//read the cache
Cache cache = cacheManager.getCache(CACHE_NAME);
//get the concurrent cache map in key-value pair
assert cache != null;
Map<SimpleKey, List<Post>> map = (Map<SimpleKey, List<Post>>) cache.getNativeCache();
//Convert to set to iterate
Set<Map.Entry<SimpleKey, List<Post>>> entrySet = map.entrySet();
Iterator<Map.Entry<SimpleKey, List<Post>>> itr = entrySet.iterator();
//if a iterated entry is a list then it is our desired data list!!! Yayyy
Map.Entry<SimpleKey, List<Post>> entry = null;
while (itr.hasNext()){
entry = itr.next();
if(entry instanceof List) break;
}
//get the list
assert entry != null;
List<Post> postList = entry.getValue();
if(method.contains("update")) {
//update it
for (Post temp : postList) {
assert post != null;
if (temp.getId().equals(post.getId())) {
postList.remove(temp);
break;
}
}
postList.add(post);
}
else if(method.contains("delete")){
//delete it
for (Post temp : postList) {
if (temp.getId().equals(postId)) {
postList.remove(temp);
break;
}
}
}
//update the cache!! :D
cache.put(entry.getKey(),postList);
return new ArrayList<>(Collections.singletonList(cacheManager.getCache(CACHE_NAME)));
}
}
Here are the methods that uses the CustomCacheResolver
#Cacheable(key = "{#pageNo,#pageSize}")
public List<Post> retrieveAllPost(int pageNo,int pageSize){ // return list}
#CachePut(key = "#post.id",cacheResolver = "customCacheResolver")
public Boolean updatePost(Post post, UserDetails userDetails){ //your logic}
#CachePut(key = "#postId",cacheResolver = "customCacheResolver")
public Boolean deletePost(Long postId,UserDetails userDetails){ // your logic}
#CacheEvict(allEntries = true)
public Boolean createPost(String userId, Post post){//your logic}
Hope it helps to manipulate your spring application cache manually!
Though I don't see any easy way, but you can override Ehcache cache functionality by supplying cache decorator. Most probably you'd want to use EhcahceDecoratorAdapter, to enhance functions used by EhCacheCache put and evict methods.
Simple and rude solution is :
#Cacheable(key = "{#pageNo,#pageSize}")
public List<Post> retrieveAllPost(int pageNo,int pageSize){ // return list}
#CacheEvict(allEntries = true)
public Boolean updatePost(Post post, UserDetails userDetails){ //your logic}
#CacheEvict(allEntries = true)
public Boolean deletePost(Long postId,UserDetails userDetails){ // your logic}
#CacheEvict(allEntries = true)
public Boolean createPost(String userId, Post post){//your logic}
