I'm not understanding how to do something that is probably very easy to do. I have a table named "Composer". A "Composer" can have many compositions ("Composition" table). I get the following error when I run this through Spring Boot:
19:11:40 web.1 | Caused by: org.hibernate.AnnotationException:
mappedBy reference an unknown target entity property:
com.zack.music.domain.Composition.composition in com.zack.music.domain.Composer.compositions
Below are my entity classes. What am I doing wrong here?
package com.zack.music.domain;
import javax.persistence.*;
import java.io.Serializable;
import java.sql.Date;
import java.util.*;
#Entity
public class Composer implements Serializable {
#Id
private String name;
private Date birth;
private Date death;
#OneToMany(mappedBy="composition")
private List<Composition> compositions;
protected Composer() { }
public Composer(String name, Date birth, Date death) {
this.name = name;
this.birth = birth;
this.death = death;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Date getBirth() {
return birth;
}
public void setBirth(Date birth) {

}
public Date getDeath() {
return death;
}
public void setDeath(Date death) {
this.death = death;
}
public List<Composition> getCompositions() {
return compositions;
}
public void setCompositions(List<Composition> compositions) {
this.compositions = compositions;
}
}
#Entity

private Composer composer;
protected Composition() { }
public Composition(String name, Composer composer) {
this.name = name;
this.composer = composer;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Composer getComposer() {
return composer;
}
public void setComposer(Composer composer) {
this.composer = composer;
}
}
mappedBy is telling hibernate the property name on the related entity that owns the relationship. There is no property named 'composition' on the related entity: Composition. You probably just meant for the value of mappedBy to be "composer".
I was able to solve it using #ElementCollection. Java Persistence/ElementCollection helped me figure it out. I also filled in the "name" attributes on all of my tables and columns which I think helped identify everything. Here are the updated entities that are working:
package com.zack.music.domain;

I am trying to create a REST service in Java with Spring Boot.
I have 2 tables Topic and Course and i want to retrieve NAME and DESCRIPTION from Topic and PRICE from Course.
The connection between these 2 tables is made with TOPIC_ID from Course.
Result MUST be a JSON.
[
{
"id": "course1",
"name": "name course1",
"description": "course1"
},
{
"id": "course2",
"name": "course2 name",
"description": "course2"
},
{
"id": "course3",
"name": "course3 name",
"description": "course3"
}
]
The query is below.
I know it's possible with DTO and JPA but I need to write a lot of code for a simple database query.
Thank you.

}
select t.name, t.description, c.price as course_price
from topic.course c
inner join topic.topic t on t.id = c.topic_id
Take advantage of the projection interface offered by Spring Data JPA:
public interface TopicDescDTO{
Integer getPrice();
String getName();
String getDescription();
}
and then just land a proper method in one of your repositories:
#Query(select t.name, t.description, c.price
from Course c
inner join c.topic t)
List<TopicDescDTO> getTopicDescs();
Spring will do the mapping for you.
I have a spring boot application which exposes resources using Spring HATEOAS. All the method GET, POST, PATCH works fine except DELETE. When I send a delete request to a resource, it returns 204 No content response but when I request for all resource, the item which I deleted appears again. No exception is logged on the console. No error in postman request.
The resource I am trying to delete is having many-to-one association with another POJO. But those resources which doesn't have many-to-one(some have one-to-many) is getting deleted.

I use MySQL as database and use Postman to test the URL
Try Changing from the cascade cascade = CascadeType.ALL)
and set cascade = CascadeType.REMOVE, orphanRemoval = true it should work

I am building an order tracking system in Spring Boot, using Hibernate annotations and Repositories. I have an Order class, which can have a list of OrderItems. These map to a ORDER and ORDER_ITEMS table respectively. The code I have representing the two is below.

this.lastDeliveryName = lastDeliveryName;
this.firstDeliveryName = firstDeliveryName;
this.deliveryAddress = deliveryAddress;
this.status = status;
this.createDate = createDate;
this.updateDate = updateDate;
}

}
public void setStatus(String status) {
this.status = status;

public Date getCreateDate() {

}
public void setCreateDate(Date createDate) {
this.createDate = createDate;
}
}
OrderItem.java
package net.township.order;
import com.fasterxml.jackson.annotation.JsonBackReference;
import org.hibernate.annotations.Cascade;
import javax.persistence.*;
#Entity
#Table(name = "order_items")
public class OrderItem {

}
public void setDescription(String description) {
this.description = description;
}
public Long getQuantity() {
return quantity;
}
public void setQuantity(Long quantity) {
this.quantity = quantity;
}
}
When I POST a new Order from my front-end, it is mapped to an Order object correctly. All OrderItems that were provided in the JSON are present in the object as a List as well. However, after I save it to the database using my OrderRepository's save method (it's just a CrudRepository), my database contains a new Order object with the correct fields, but nothing is ever created in ORDER_ITEMS.
I've poked around the documentation for both Hibernate and JPA OneToMany annotations, and I don't see where I'm going wrong here. I'll also add that I'm doing no manual schema creation, letting SpringBoot handle setting up everything in H2 for me.
This is what ultimately worked for me.

Add CascadeType.ALL to your mapping.
I have the following code that is not working properly.
testprovincia exist on data base and the partidos variable is a list that I am sure is not empty but is never persisted too.
mgr = getPersistenceManager();
Query query = mgr.newQuery(Provincia.class);
query.setFilter("name == nameParam");
query.declareParameters("String nameParam");
List<Provincia> results = (List<Provincia>) query.execute("testprovincia");
Provincia prov = results.get(0);
insertPartidos(partidos);
prov.setPartidos(partidos);
mgr.makePersistent(prov);
query.closeAll();
mgr.close();
InsertPartidos method:
private void insertPartidos(List<Partido> partidos){
for (Partido partido : partidos) {
log.info(partido.getName());
mgr.makePersistent(partido);
}
}
The question is why I never see the list I added to prov variable on the database? Is allways empty.
Here are my classes:
#PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Provincia {
public Provincia(String name) {
super();
this.name = name;
}
#PrimaryKey
#Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
#Persistent
private String name;
#Persistent(mappedBy = "provincia")
#Order(extensions = #Extension(vendorName="datanucleus",key="list-ordering", value="name asc"))
private List<Partido> partidos;
public Key getId() {
return id;
}
public void setId(Key id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Partido> getPartidos() {
return partidos;
}
public void setPartidos(List<Partido> partidos) {
this.partidos = partidos;
}
}
#PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Partido {
#PrimaryKey
#Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
#Persistent
private String name;
#Persistent
private Provincia provincia;
public Partido(){
}
public Partido(Key id) {
super();
this.id = id;
}
public Partido(Key id, String name, Provincia prov) {
super();
this.id = id;
this.name = name;
this.provincia = prov;
}
public Partido(String name, Provincia prov) {
super();
this.name = name;
this.provincia = prov;
}
public Key getId() {
return id;
}
public void setId(Key id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Provincia getProvincia() {
return provincia;
}
public void setProvincia(Provincia provincia) {
this.provincia = provincia;
}
}
Maybe using the other way of updating. If testprovincia already exists, using the method described here might do the trick for you. Instead of using makepersistent, grab your data with the persistence manager and straight update it.
That or use standard datastore's db (or ndb) puts, as explained here? Do you REALLY need the JDO?
I'm just learning to develop a REST application using JAXB and JPA. I'm stuck in weird problem and I have no clue what to search for.

When I have a patient entry in the database, the service is able to map entities into XML/JSON. But when I add an associating prescription entry, Glassfish throws error 500.
What could be the problem?
I'm using GlassFish 4.0 and EclipseLink 2.5.1. IDE is Eclipse Luna.

The exception can be seen if a string is returned instead of the POJO object and the marshaling is done manually.
