JPA: Prevent cascade update in unidirectional onetomany mapping

I've a parent entity named QuestionPaper:
#Entity
#Table(name = "question_paper")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaper {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_id", columnDefinition = "INT")
private int questionPaperId;
#Column(nullable = false, length = 150)
private String name;
#OneToMany
#JoinColumn(name = "question_paper_id")
#OrderBy("order")
private Set<QuestionPaperCategory> questionPaperCategorys = new HashSet<QuestionPaperCategory>();
}
and a child entity QuestionPaperCategory:
#Entity
#Table(name = "question_paper_category")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaperCategory {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_category_id", columnDefinition = "INT")
private int questionPaperCategoryId;
#Column(name = "question_paper_id")
private int questionPaperId;
....
}
I want to update just QuestionPaper without updating the child rows (QuestionPaperCategory). Just change the name field.
So, I tried
QuestionPaper qPaper = new QuestionPaper();
qPaper.setQuestionPaperId(1)
qPaper.setName("Exam-101")
qPaperRepository.save(qPaper);
But it is throwing the following error. I think it's trying to cascade update the child tables. I want to prevent that.

It shows this query in the error.[update question_paper_category set question_paper_id=null where question_paper_id=?]
Why is it trying to update question_paper_category when I've not set in in QuestionPaper

Instead of creating new object, you have two ways of updating entities. First - fetch your entity, update fields and save:
QuestionPaper qPaper = qPaperRepository.findOne(1);
qPaper.setName("Exam-101")
qPaperRepository.save(qPaper);
In this you will update only fields you want, other fields will be unaffected. Notice, that if you are using lazy loading you will not fetch all related entities.
Second is to create update by repository without fetching entity:
#Modyfing
#Query("update QuestionPaper qp set qp.name= ?2 where qp.questionPaperId = ?1")
void updateName(String id, String name);
Of course, if you want to update more fields you can put more parameters into your query.

I believe the root of the problem is you have an auto generated Id, but you are creating a new instance and manually specifying it.
Try leaving your Id null and let the auto generation do it's thing.
Alternatively if you are trying to update an existing record, retrieve the record first then edit it. There will be no need to set the Id for this approach because it will already be in the retrieved object.
Additionally your joining column should be specified in your #OneToMany.

In the QuestionPaper.java, you can config the value of the cascade attribute about the #OneToMany,and delete the annotation of #JoinColumn(name = "question_paper_id") what should be used in the #ManyToOne.
#Entity
#Table(name = "question_paper")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaper {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_id", columnDefinition = "INT")
private int questionPaperId;
#Column(nullable = false, length = 150)
private String name;
#OneToMany(mappedBy="questionPaper", fetch=FetchType.LAZY)
// #JoinColumn(name = "question_paper_id")
// #OrderBy("order")
private Set<QuestionPaperCategory> questionPaperCategorys = new HashSet<QuestionPaperCategory>();
}
QuestionPaperCategory.java
#Entity
#Table(name = "question_paper_category")
#JsonIgnoreProperties(ignoreUnknown = true)
public class QuestionPaperCategory {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "question_paper_category_id", columnDefinition = "INT")
private int questionPaperCategoryId;
// #Column(name = "question_paper_id")
// private int questionPaperId;
#ManyToOne(fetch=FetchType.LAZY)
private QuestionPaper questionPaper;

I have the test. It works.

Why my hibernate relation doesn't work?

See my class with relation :
#Entity
#Table(name = "t_aquarium")
public class UserPoissonDO {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "id")
private Integer id;
#ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH })
private User user;
#ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH })
private PoissonDO poissonDO;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public PoissonDO getPoissonDO() {
return poissonDO;
}
public void setPoissonDO(PoissonDO poissonDO) {
this.poissonDO = poissonDO;
}
}
When I save it in my BDD with JPA, I've the following error :
detached entity passed to persist: com.javaquarium.beans.data.PoissonDO;
nested exception is org.hibernate.PersistentObjectException: detached entity
passed to persist: com.javaquarium.beans.data.PoissonDO
In my database, I like to save the UserPoissonDO object with relation to the User and the specie of the Fish.
UserPoisson is associated with one User and one User can have more than one fish.
I think my relation is bad... if it's the case explain me why. I've follow an example for this.
EDIT :
See my PoissonUserService for persisting UserPoissonDO

I believe the solution provided here: Spring data jpa detached entity, will also work for this situation.
The issue is that UserPoissonDO is a new object, but its PoissonDO is detached. Spring will attempt to persist UserPoissonDO since it is a new object, but doesn't know that it needs to merge() PoissonDO into the existing persistence context and manage it.
As explained in the linked post:
If you can ensure that PoissonDO will be saved separately or already exists, removing CascadeType.PERSIST will work. Otherwise, you will need to perform a merge() using a custom repository and EntityManager.

Unable to create a custom method using findBy prefix in springJPA

I have table entity called topics with columns as:
id
topic_id
title
details
day_posted
username
userImage
how do I created a custom method so that I retrieve the information from above table based on column topic_id
I have table entity/bean class defined:
#Entity
#Table(name = "topics")
public class TopicBean implements Serializable {
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "topic_id")
private String topic_id;
#Column(name = "title")
private String title;
#Column(name = "details")
private String details;
#Column(name = "username")
private String username;
#Column(name = "user_image")
private String user_image;
#Column(name = "day_posted")
private String day_posted;
//getter and setters
}
Interface:
public interface TopicRepository extends JpaRepository<TopicBean, Long> {
TopicBean findByTopic_id(String topic_id);
}
Service Interface:
public interface TopicService {
TopicBean findById(long id);
TopicBean findByName(String name);
void saveTopic(TopicBean topicBean);
void updateTopic(TopicBean topicBean);
TopicBean findByTopic_id(String id);
void deleteTopicById(long id);
List<TopicBean> findAllTopics();
void deleteAllTopics();
public boolean isTopicExist(TopicBean topicBean);
}
ServiceImpl:
#Component
public class TopicServiceImplementation implements TopicService {
#Autowired
private TopicRepository topicRepository;
#Override
public TopicBean findById(long id) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public TopicBean findByName(String name) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public void saveTopic(TopicBean topicBean) {
topicRepository.save(topicBean);
}
#Override
public void updateTopic(TopicBean topicBean) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public void deleteTopicById(long id) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public List<TopicBean> findAllTopics() {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public void deleteAllTopics() {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public boolean isTopicExist(TopicBean topicBean) {
throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
#Override
public TopicBean findByTopic_id(String id) {
return topicRepository.findByTopic_id(id);
}
}
When I run the GET request like this:
#RequestMapping(path = "/get_topic_details", method = RequestMethod.GET)
public ResponseEntity get_topic_details(#RequestParam(value="topic_id") String topic_id) throws Exception {
topicService.findByTopic_id(topic_id);
HttpHeaders headers = new HttpHeaders();
headers.add("success", "topic added");
return new ResponseEntity(headers, HttpStatus.OK);
}
I get error:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'topics': Unsatisfied dependency expressed through field 'topicService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'topicServiceImplementation': Unsatisfied dependency expressed through field 'topicRepository'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'topicRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property topic found for type TopicBean!

Avoid using underscore in property names, spring doesn't like it and prefers the standard java naming convention.
Your Entity should look like this.
#Entity
#Table(name = "topics")
public class TopicBean implements Serializable {
#Id
#Column(name = "id")
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Column(name = "topic_id")
private String topicId;
#Column(name = "title")
private String title;
#Column(name = "details")
private String details;
#Column(name = "username")
private String username;
#Column(name = "user_image")
private String userImage;
#Column(name = "day_posted")
private String dayPosted;
//getter and setters
}
And based on the above property names create your repository and service method.
Ref: http://docs.spring.io/spring-data/jpa/docs/current/reference/html/#repositories.query-methods.query-property-expressions

I had similar issue and removing _ in the variable name worked for me. I think Spring Data ignores _ in variable names. Even from the error its trying to find the property topic instead of topic_id. Remove _ and try, i believe it should work

Initialization of an object via #Query request

I have StateArchiveDTO class with field Collection<StatePropertyEntity> stateProperties.
Now I'm trying to create page of objects StateArchiveDTO from MySQL database. But I can't deal with the collection.
public interface StateArchiveRepository extends JpaRepository<StateArchiveEntity,Long>{
#Query(value = "SELECT new com.MyProject.endpoints.dto.StateArchiveDTO(stateArchive.id, stateArchive.type, stateArchive.created, stateArchive.updated, stateArchive.version, stateArchive.stateProperties) " +
"FROM StateArchiveEntity stateArchive "
)
Page<StateArchiveDTO> getStateArchive(Pageable pageable);
}
Response from controller:
{
"timestamp": 1478599659554,
"status": 500,
"error": "Internal Server Error",
"exception": "org.springframework.dao.InvalidDataAccessResourceUsageException",
"message": "could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet",
"path": "/statistics/states-history"
}
When I initialize all fields except Collection<StatePropertyEntity> all works fine:
public interface StateArchiveRepository extends JpaRepository<StateArchiveEntity,Long>{
#Query(value = "SELECT new com.MyProject.endpoints.dto.StateArchiveDTO(stateArchive.id, stateArchive.type, stateArchive.created, stateArchive.updated, stateArchive.version) " +
"FROM StateArchiveEntity stateArchive "
)
Page<StateArchiveDTO> getStateArchive(Pageable pageable);
}
How to initialize all fields of StateArchiveDTO in #Query?

You need to add default constructors to your DTO class because you are trying to create a new instance for DTO in the Repository Query.
The below is applicable for Entity class (StateArchiveEntity), which you already have.
The default constructor only exists for the sake of JPA. You won’t use
it directly, so it is designated as protected.
You can look at here

How to join two tables using JPA Criteria Builder?

I have an sql table called school, and another called student. Every school has an ID, and every student has a "school ID", which is the ID of the school they belong to.
Now I want to find all schools in which there is a student called "John".
The SQL syntax would be something like :
SELECT * FROM school
INNER JOIN student
on student.school_id = school.id
where student.name = "John"
However, I have to use the Spring Boot Specification to make my Query (ie use it like) :
schoolDao.findAll(new mySpecification("John"));
I have to use that because there is already a Specification and I just want to add a new on top of it :
schoolDao.findAll(
(Specification) Specifications.where(new oldSpecification(), new mySpecification("John"));
So how can I do that ?
I tried
public Predicate toPredicate(Root<T> root, CriteriaQuery<?> query, CriteriaBuilder cb) {
if (this.filterTag == "") {
return null;
}
Class clazz = query.getResultType();
if (clazz.equals(Long.class) || clazz.equals(long.class)) {
return null;
}
Join<School,Student> tags = root.join("student", JoinType.LEFT);
return cb.equal(tags.get("name"), "John");
}
but it doesn't work. Anyone can help ?
EDIT : The Student class
#Entity
#Table(name = "student")
public class Student implements Serializable {
private static final long serialVersionUID = 1L;
#ManyToOne
private Long schoolId;
private String name;
public Long getSchoolId() {
return schoolId;
}
public void setSchoolId(Long schoolId) {
this.schoolId = schoolId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
and the School class :
#Entity
#Table(name = "school")
public class School implements Serializable {
private static final long serialVersionUID = 1L;
//other fields
#OneToMany(targetEntity = Student.class, mappedBy = "schoolId")
#Transient
private List<Student> students = new ArrayList<Student>();
//all getters and setters
}
EDIT 2 :
The error is
java.lang.IllegalArgumentException: Unable to locate Attribute with the the given name [student] on this ManagedType [School]

Thanks

This is how I do it
EntityManager em = emf.createEntityManager();
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Object> cq = cb.createQuery();
Root<Item> ri = cq.from(School.class);
// joins
Join<Object, Object> h = ri.join("Student");
Query query = em.createQuery(cq);
List<Object[]> result = query.getResultList();
But as you have your Entities setup, which not just use JPA?
