Thanks all, i resolved the problem.
the problem in name of the entity "Package", its reserved in Java 😂

Referring to the getting started link below
https://quarkus.io/guides/hibernate-orm-panache
The example uses a Entity class with public attributes.
class Person{
public String name;
}
and used as
person.name = "Synd";
so is it simply a lazy example (!! in official doc ? ) or it means something else.
According to the documentation, it might be related to a single difference (extending PanacheEntityBase)
If you don’t want to bother defining getters/setters for your entities, you can make them extend PanacheEntityBase and Quarkus will generate them for you. You can even extend PanacheEntity and take advantage of the default ID it provides.
Therefore they are making them Public for Quarkus to generate getters/setters for you automatically.
#Entity
public class Person extends PanacheEntity {
public String name;
public LocalDate birth;
public Status status;
public static Person findByName(String name){
return find("name", name).firstResult();
}
public static List<Person> findAlive(){
return list("status", Status.Alive);
}
public static void deleteStefs(){
delete("name", "Stef");
}
}
vs
#Entity
public class Person {
#Id #GeneratedValue private Long id;
private String name;
private LocalDate birth;
private Status status;
public Long getId(){
return id;
}
public void setId(Long id){
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public LocalDate getBirth() {
return birth;
}
public void setBirth(LocalDate birth) {
this.birth = birth;
}
public Status getStatus() {
return status;
}
public void setStatus(Status status) {
this.status = status;
}
}
I am using the debugger in IntelliJ and right before the point of returning the result, the array is perfectly fine, as you can see here
But for some reason, the response in the browser looks like this
I don't understand why the fields are invisible.
This is what my 2 models look like:
Municipality:
#Entity
public class Municipality {
#Id
#JsonIgnore
#GeneratedValue(strategy = GenerationType.IDENTITY)
Long id;
String name;
}
Prediction
#Entity
public class Prediction {
#Id
#JsonIgnore
#GeneratedValue(strategy = GenerationType.IDENTITY)
Long id;
LocalDateTime tsPredictionMade;
LocalDateTime tsPredictionFor;
float pm10;
float pm25;
#ManyToOne
#OnDelete(action = OnDeleteAction.CASCADE)
Municipality municipality;
}
And this is my controller:
#RestController
#RequestMapping("/predict")
public class PredictionController {
private MunicipalityService municipalityService;
private PredictionService predictionService;
#Autowired
public PredictionController(MunicipalityService municipalityService, PredictionService predictionService) {
this.municipalityService = municipalityService;
this.predictionService = predictionService;
}
#GetMapping
public List<Municipality> getPredictions(){
List<Municipality> result = municipalityService.getPredictions();
return result;
}
#GetMapping("/{municipality}")
public List<Prediction> getPredictionsForMunicipality(#PathVariable("municipality") String name){
List<Prediction> result = predictionService.getPredictions(name);
return result;
}
}
The rest of the app (service and persistence layer) is pretty standard.
What is the reason for this?
You will need the getters and setters for your models. The Jackson library needs it for accessing its fields when converting the models into JSON, differently from JPA when converting the resultSet into models. Here is the code:
Prediction
#Entity
public class Municipality {
#Id
#JsonIgnore
#GeneratedValue(strategy = GenerationType.IDENTITY)
Long id;
String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public LocalDateTime getTsPredictionMade() {
return tsPredictionMade;
}
public void setTsPredictionMade(LocalDateTime tsPredictionMade) {
this.tsPredictionMade = tsPredictionMade;
}
public LocalDateTime getTsPredictionFor() {
return tsPredictionFor;
}
public void setTsPredictionFor(LocalDateTime tsPredictionFor) {
this.tsPredictionFor = tsPredictionFor;
}
public float getPm10() {
return pm10;
}
public void setPm10(float pm10) {
this.pm10 = pm10;
}
public float getPm25() {
return pm25;
}
public void setPm25(float pm25) {
this.pm25 = pm25;
}
public Municipality getMunicipality() {
return municipality;
}
public void setMunicipality(Municipality municipality) {
this.municipality = municipality;
}
}
Municipality
#Entity
public class Municipality {
#Id
#JsonIgnore
#GeneratedValue(strategy = GenerationType.IDENTITY)
Long id;
String name;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
You need getters and setter for each field that you want to expose.
You can use #Data from lombok project to avoid boilerplate code.

My AuditListener
public class EmployeeAuditListeners {
#PrePersist
public void prePersist(Employee employee){
perform(employee,Action.INSERTED);
}
#PreUpdate
public void preUpdate(Employee employee){
perform(employee,Action.UPDATED);
}
#PreRemove
public void preRemove(Employee employee){
perform(employee,Action.DELETED);
}
#Transactional
public void perform(Employee emp, Action action){
EntityManager em = BeanUtil.getBean(EntityManager.class);
CommonLogs commonLogs = new CommonLogs();
commonLogs.setQuery("new query");
em.persist(commonLogs);
}
}
and My Auditable.class
#MappedSuperclass
#EntityListeners(AuditingEntityListener.class)
public abstract class Auditable<U> {
#CreatedBy
protected U createdBy;
#CreatedDate
#Temporal(TemporalType.TIMESTAMP)
protected Date createdDate;
#LastModifiedBy
protected U lastModifiedBy;
#LastModifiedDate
#Temporal(TemporalType.TIMESTAMP)
protected Date lastModifiedDate;
}
My CommonLogs.class
#Entity
#EntityListeners(AuditingEntityListener.class)
public class CommonLogs extends Auditable<String> {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String query;
public CommonLogs() {
}
public CommonLogs(String query) {
this.query = query;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getQuery() {
return query;
}
public void setQuery(String query) {
this.query = query;
}
}
My Employee.java class
#Entity
#EntityListeners(EmployeeAuditListeners.class)
public class Employee {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name;
private String address;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
and I have a simple Rest Controller
#RestController
#RequestMapping("/api")
public class EmployeeController {
#Autowired
private EmployeeRepository employeeRepository;
#PostMapping("/employees")
public Employee createEmployee(#RequestBody Employee employee){
return employeeRepository.save(employee);
}
}
I want to log it on my table (common_logs) every time i perform some crud operations on my Employee Entity.
the above given example is working to some extent as it successfully stores employee and invokes EmployeeAuditListeners.
but now while saving CommongLog entity i expect it's parent class Auditable to automatically insert createdBy, createdDate etc. for now only query and id is inserted on common_logs table and remaining columns are null.
You can review the documentation for Auditing in here.
To enable the automatic Auditing, you must add the annotation #EnableJpaAuditing in your Application class:
#SpringBootApplication
#EnableJpaAuditing
class Application {
static void main(String[] args) {
SpringApplication.run(Application.class, args)
}
}
If you want the fields #CreatedBy and #LastModifiedBy too, you will also need to implement the AuditorAware<T> interface. For example:
class SpringSecurityAuditorAware implements AuditorAware<User> {
public User getCurrentAuditor() {
Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
if (authentication == null || !authentication.isAuthenticated()) {
return null;
}
return ((MyUserDetails) authentication.getPrincipal()).getUser();
}
}
I have a simple Model in Java called Member with fields - ID (Primary Key), Name (String), Position (String)
I want to expose an POST endpoint to update fields of a member. This method can accept payload like this
{ "id":1,"name":"Prateek"}
or
{ "id":1,"position":"Head of HR"}
and based on the payload received, I update only that particular field. How can I achieve that with JPARepository?
My repository interface is basic -
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository("memberRepository")
public interface MemberRepository extends JpaRepository<Member, Integer>{
}
My Member model -
#Entity
#Table(name="members")
public class Member {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name="member_id")
private Integer id;
#Column(name="member_name")
#NotNull
private String name;
#Column(name="member_joining_date")
#NotNull
private Date joiningDate = new Date();
#Enumerated(EnumType.STRING)
#Column(name="member_type",columnDefinition="varchar(255) default 'ORDINARY_MEMBER'")
private MemberType memberType = MemberType.ORDINARY_MEMBER;
public Member(Integer id, String name, Date joiningDate) {
super();
this.id = id;
this.name = name;
this.joiningDate = joiningDate;
this.memberType = MemberType.ORDINARY_MEMBER;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Date getJoiningDate() {
return joiningDate;
}
public void setJoiningDate(Date joiningDate) {
this.joiningDate = joiningDate;
}
public MemberType getMemberType() {
return memberType;
}
public void setMemberType(MemberType memberType) {
this.memberType = memberType;
}
public Member(String name) {
this.memberType = MemberType.ORDINARY_MEMBER;
this.joiningDate = new Date();
this.name = name;
}
public Member() {
}
}
Something like this should do the trick
public class MemberService {
#Autowired
MemberRepository memberRepository;
public Member updateMember(Member memberFromRest) {
Member memberFromDb = memberRepository.findById(memberFromRest.getid());
//check if memberFromRest has name or position and update that to memberFromDb
memberRepository.save(memberFromDb);
}
}
I am getting this exception nested exception is org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.ibm.ro.model.Location.subLocations, could not initialize proxy - no Session.
I do get that upon accessing the collection, the transaction has already been closed that's why the code is throwing this exception. Here is my sample code
#Entity
#Table(name="location")
public class Location extends BaseEntity {
private static final long serialVersionUID = 1L;
private String name;
private List<Location> subLocations;
private Location location;
#Column(name="name")
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#OneToMany(fetch = FetchType.LAZY, mappedBy = "location")
public List<Location> getSubLocations() {
return subLocations;
}
public void setSubLocations(List<Location> subLocations) {
this.subLocations = subLocations;
}
#ManyToOne(fetch = FetchType.LAZY)
public Location getLocation() {
return location;
}
public void setLocation(Location location) {
this.location = location;
}
#Override
public String toString() {
return "Location [name=" + name + ", subLocations=" + subLocations
+ "]";
}
}
Here is my DAO:
#Repository("locationDao")
public class LocationDao implements ILocationDao{
#Autowired
private SessionFactory sessionFactory;
#Override
public List<Location> getAll() {
Session sess = getSession();
return sess.createCriteria(Location.class).setResultTransformer(CriteriaSpecification.DISTINCT_ROOT_ENTITY).list();
}
}
Then here is my service :
#Service("locationService")
#Transactional
public class LocationService implements ILocationService{
#Autowired
ILocationDao dao;
#Override
public List<Location> getAll() {
return dao.getAll();
}
}
Here is the controller where the exception is being thrown:
#Controller
public class BaseController {
#Autowired
ILocationService service;
private static final String VIEW_INDEX = "index";
private final static org.slf4j.Logger logger = LoggerFactory.getLogger(BaseController.class);
#RequestMapping(value = "/", method = RequestMethod.GET)
public String location(ModelMap model) {
logger.debug(service.getAll().toString());
return VIEW_INDEX;
}
}
What can I do to fix the problem without using OpenSessionInViewFilter?
You can iterate your Location inside your service (where you still have your transaction) and call Hibernate.initialize on the elements, the force initialization of a persistent collection.
#Override
public List<Location> getAll() {
List<Location> locations = dao.getAll();
for (Location location : locations ) {
Hibernate.intialize(location.getSubLocations())
}
return locations;
}
