I am using spring #Transactional to manage MySQL transactional.
But the way I add #Transactional is wrong.
#Service
//#Transactional(readOnly = true)
public class UserInfoService extends BaseService
#Autowired
private UserInfoAccessor userInfoAccessor;
//#Transactional
public void insert()
Map<String, String> map = new HashMap<>();
map.put("userName", "test");
userInfoAccessor.insert(map);
The error message I receive is:
Unable to instantiate Action, com.luotuo.xiaobao.action.IndexAction, defined for 'index' in namespace '/'Error creating bean with name 'com.luotuo.xiaobao.action.IndexAction': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.luotuo.xiaobao.service.UserInfoService com.luotuo.xiaobao.action.IndexAction.userInfoService; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.luotuo.xiaobao.service.UserInfoService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: #org.springframework.beans.factory.annotation.Autowired(required=true)
You can download my project source here.
What is the correct way to set this up?

With a configuration class you could initialize your beans manually, specially if they need custom names.
#Configuration
public class MyCustomConfiguration {
#Bean(name ="headerProcessor")
public ItemProcessor<FileHeader, FileHeader> headerProcessorBean() {
ItemProcessor<FileHeader, FileHeader> myBean = new HeaderProcessor<>();
//Do whaterever you need to initilize your bean
return myBean;
}
#Bean(name ="detailProcessor")
public ItemProcessor<FileDetail, FileDetail> detailProcessorBean() {
ItemProcessor<FileDetail, FileDetail> myBean = new ItemProcessor<>();
//Do whaterever you need to initilize your bean
return myBean;
}
}
In this way these beans will be available for autowiring.
I wanted to move from JdbcTemplate to Spring Data JDBC. However I seem to have some misconfiguration but I cannot figure out where. The errors are "expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}" and "Parameter 0 of constructor ... required a bean ... that could not be found."
I put #Repository on the public repository interfaces extending PagingAndSortingRepository (as I did with the DAO classes extending from JdbcDaoSupport) without success. Then I added #EnableJdbcRepositories with and without package name to the database config class, also no success. I also tried the database config to inherit from AbstractJdbcConfiguration, still the same errors ...
Unfortunately I couldn't find a working example and I now gave up after some trial and error. I still would love to get this working, the version I used is spring-boot-starter-data-jdbc:2.4.0
Code fragments:
DatabaseConfiguration.java
#Configuration
#EnableJdbcRepositories("<basepackage>.repository.jdbc")
#EnableJdbcAuditing(auditorAwareRef = "springSecurityAuditorAware")
#EnableJpaRepositories("<basepackage>.repository")
#EnableJpaAuditing(auditorAwareRef = "springSecurityAuditorAware")
#EnableTransactionManagement
#EnableElasticsearchRepositories("<basepackage>.repository.search")
public class DatabaseConfiguration extends AbstractJdbcConfiguration {
}
UserRepository.java
#Repository
public interface UserRepository extends PagingAndSortingRepository<User, String> {
}
QualityResource.java (REST Controller)
public QualityResource(UserRepository userRepository) {
this.userRepository = userRepository;
}
Error messages:
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'qualityResource' defined in file [.../backend/build/classes/java/main/.../web/rest/QualityResource.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type '....repository.jdbc.UserRepository' available: expected at least 1 bean which qualifies as autowire candidate.

I am trying to unit test my rest api controller. Controller code is as below
#RestController
#RequestMapping("/events")
public class EventController {
#Autowired
private EventService eventService;
#GetMapping
public Iterable<Event> getEvents(EventSearchFilter filter, #PageableDefault(page = 1, size = 5, sort = "location.city, asc") Pageable pageable) {
return eventService.findEventsOnCondition(filter, pageable);
}
...
}
Test class is
#RunWith(SpringRunner.class)
#WebMvcTest(EventController.class)
public class EventEndpointTest {
private MockMvc mockMvc;
#InjectMocks
private EventController eventController;
#Mock
private EventService eventService;
#InjectMocks
private PageableHandlerMethodArgumentResolver pageableArgumentResolver;
#Before
public void setup() {
MockitoAnnotations.initMocks(this);
this.mockMvc = MockMvcBuilders.standaloneSetup(eventController).setCustomArgumentResolvers(pageableArgumentResolver).build();
}
#Test
public void getEvents() throws Exception{
Event event = new Event();
event.setName("TestName");
EventSearchFilter filter = new EventSearchFilter();
filter.setName("TestName");
List<Event> eventList = singletonList(event);
given(eventController.getEvents(any(EventSearchFilter.class), any(PageRequest.class))).willReturn(eventList);
mockMvc.perform(get("/events")
.contentType(APPLICATION_JSON))
.andExpect(status().isOk());
}
...
}
However, I got error complaining saying I have Error creating bean with name 'eventController':
Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'EventService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}.
As I got above error, I tried use Autowired annotation for my EventService. It still doesn't work. any ideas? Thanks.
I found a solution. All I need to do is replacing #WebMvcTest(EventController.class) in my Test class to #SpringBootTest(classes = Application.class). Thanks guys.
Did you declare #Service annotation at EventService?
#Service
public class EventService {
...something code..
}
I guess Spring cannot find bean named EventService
I had a similar issue where the stack trace showed
java.lang.IllegalStateException: Failed to load ApplicationContext
...
...
Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'Controller': Unsatisfied dependency expressed through field 'i18NService';

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type '...Service' available:

and ultimately the solution was that the services needed to be mocked with #MockBean since regular components (including services and repositories) will not be scanned.
Same answer with #DFeng. Encountered the below error:
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mysqlRedisCachingController': Unsatisfied dependency expressed through field 'mysqlRedisBusinessService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mysqlRedisBusinessService': Unsatisfied dependency expressed through field 'mysqlRedisService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'mysqlRedisService': Unsatisfied dependency expressed through field 'mysqlRedisRepository'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.example.caching.redismanager.repo.MysqlRedisRepository' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'com.example.caching.redismanager.repo.MysqlRedisRepository' in your configuration.
This annotation did the trick.
#MockBean
Added the below in the Test Class:
#MockBean
private MysqlRedisRepository mysqlRedisRepository;
#Test
void contextLoads() {}
It works as expected. Hope this helps.
I am trying to create a bean that is valid only for a single request that contains a user's roles. I will populate the roles in an #Around method prior to calling any controller methods. I then need to access these roles later for other authorization checks.
#Component
#Aspect
public class SecurityAudit {
#Autowired
private CurrentRoles currentRoles;
#Around("#annotation(requestMapping) && execution( *
com.myapp.controller..*.*(..))")
public Object around(ProceedingJoinPoint pjp, RequestMapping requestMapping)
throws Throwable {
...
...
//I populate the roles with a db lookup. They will be referenced here, and later in controller methods as-needed.
}
}
package com.myapp.model;
...
...
#JsonInclude(JsonInclude.Include.NON_NULL)
#Generated("org.jsonschema2pojo")
#JsonPropertyOrder({
"sso",
"roles"
})
#Component
#Scope(value="request", proxyMode=ScopedProxyMode.TARGET_CLASS)
public class CurrentRoles {
#JsonProperty("roles")
private Set<Role> roles;
...
...
}
I get the following:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityAudit': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.myapp.model.CurrentRoles com.myapp.currentRoles; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.myapp.model.CurrentRoles] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {#org.springframework.beans.factory.annotation.Autowired(required=true)}
The Aspect is created at startup. I would have though the injected request-scoped bean would stay null until requests start coming in, then I could populate the currentRoles bean for that specific request.
Most probably you forgot #Service annotation in your Service class ;)
I am trying to #Autowired a class which is a simple class, without Annotations, is just a class which has some calculation. However when I try to #Autowired that class, in my controller I get the following error:
Controller:
#Controller
public class LeituraController extends HemisphereController {
private static final String VIEW = "calculation/index";
#Autowired
private MyClass evapo;
#RequestMapping(value = "/request", method = RequestMethod.GET)
#SuppressWarnings("unchecked")
public ModelAndView leituras() {
ModelAndView view = new ModelAndView(VIEW);
Double valorMax = evapo.calculation();
return view;
}}
Example of class:
public class MyClass {
public Double calculation(){
//implementation
}
}

Anybody could help me? Thanks.
The injected MyClass instance must be a Spring bean. Annotate it with #Component or another bean annotation, or declare it in the spring XML config file.
