Spring Data doesn't update with save() method

Spring Data doesn't update with save() method - java

I'm currently working on an application for an university project. For this project, my team and I are using a Vaadin/Spring/Maven configuration. With this we also include a database connected with repositories.
The repositories are build the following way. First a class for objects:
import javax.persistence.*;
import java.util.Set;
#Entity
#Table (name = "component")
public class Component {
#Id #GeneratedValue(strategy = GenerationType.AUTO)
long id;
String name;
float price;
boolean isVegetarian;
#OneToMany(mappedBy = "component", cascade = {CascadeType.PERSIST, CascadeType.REFRESH}, fetch = FetchType.EAGER)
Set<InvoicePosition> Positions;
#ManyToOne(cascade = CascadeType.PERSIST, fetch = FetchType.EAGER)
ComponentCategory category_id;
String path;
public Component() {
}
public Component(String name, float price, boolean isVegetarian, ComponentCategory category, String path) {
this.name = name;
this.price = price;
this.isVegetarian = isVegetarian;
this.category_id = category;
this.path = path;
}
Then the additional repository:
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface ComponentRepository extends JpaRepository<Component, Long>{}
Then there is a repository for component category, in which we should be able to store a list of components:
import javax.persistence.*;
import java.util.ArrayList;
import java.util.List;
#Entity
#Table(name = "componentCategory")
public class ComponentCategory {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
Long id;
String name;
#OneToMany(mappedBy = "category_id", cascade = CascadeType.PERSIST, fetch = FetchType.EAGER)
List<Component> components;
public ComponentCategory() { }
public ComponentCategory(String name) {
this.name = name;
components = new ArrayList<>();
}
public void addComponentToCategory(Component component) {
if(!components.contains(component))
{
components.add(component);
component.category_id = this;
}
}
And then the same repository:
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;
#Repository
public interface ComponentCategoryRepository extends JpaRepository<ComponentCategory, Long> {}
I am able to create new entries and they are also properly stored in the database. This is all stored in the Application.Java file to start the Vaadin application
ComponentCategory cat1 = new ComponentCategory("examp1");
Component test1 = new Component("example1", 1.25f, true, cat1, "");
Component test2 = new Component("example2", 0.89f, true, cat1, "");
cat1.addComponentToCategory(test1);
cat1.addComponentToCategory(test2);
compcatrep.saveAndFlush(comp); // compcatrep is the ComponentCategoryRepository, which is passed on to the init() function
Now I'm trying to update the entries in the database with the following logic:
Component test11 = new Component("Test", 2.15f, true, compcatrep.getOne((long)4), "");
ComponentCategory comp = compcatrep.getOne((long)4);
comp.addComponentToCategory(test11);
compcatrep.saveAndFlush(comp);
I made sure that there is an entry with the ID (long) 4. It does work and does not show me any error, when I execute the application. Also if I check the length of the stored list in the ComponentCategory after the saveAndFlush():
System.out.println(comp.getComponents().size());
System.out.println(compcatrep.getOne((long)4).getComponents().size());
I do receive different length of the lists. The second Syso does show one less then the first. I tried a lot and did not find the error. Some more information about my issue:

Postman Get request returns duplicate results

When I issue a Postman Get request, it returns duplicate result. Even when I had only three records in my database, Postman returns hundreds of same record duplicated.

The issue you are facing is quite abstract. "Postman returns hundreds of same record duplicated." does not tell us much. Still, I guess that the issue is your bi-directional relationship. Try adding #JsonManagedReference and #JsonBackReference to your bi-directional relationship in your model as follows:
#JsonManagedReference
#OneToOne(mappedBy = "question",cascade = CascadeType.ALL)
private ChemistryAnswer answer = new ChemistryAnswer();
#OneToOne
#JsonBackReference
#JoinColumn(name = "question_id")
private Chemistry question;

but when i run my project through Boot Dashboard with right click and start my project it run normally. and my api work fine. i do some try.
first trying my code is looked like below, i have mapper file that looked like this :
#Mapper(componentModel = "spring")
public interface ICategoryBpsjMapper {
ICategoryBpsjMapper INSTANCE = Mappers.getMapper(ICategoryBpsjMapper.class);
#Mappings({
#Mapping(target = "createdDate", dateFormat = "dd-MM-yyyy HH:mm:ss"),
#Mapping(target = "modifiedDate",dateFormat = "dd-MM-yyyy HH:mm:ss")})
CategoryBpsjResponseDto entityToDto(CategoryBPSJ entity);
CategoryBPSJ DTOEntity(CategoryBPSJDto dto);
CategoryBPSJ updateEntityFromDto(CategoryBPSJDto dto, #MappingTarget CategoryBPSJ entity);
List<CategoryBpsjResponseDto> entityToDto(List<CategoryBPSJ> entityList);
List<CategoryBPSJ> DTOEnity(List<CategoryBPSJDto> dtoList);
}
and here is my entity :
#Data
#Entity
#Audited
#EntityListeners(AuditingEntityListener.class)
#EqualsAndHashCode(of = "id")
#ToString(of = {"id"})
#Table(name = "msCategoryBPSJ", uniqueConstraints = {
#UniqueConstraint(name = "uk_categoryBPSJName", columnNames = { "categoryBPSJName" })})
public class CategoryBPSJ extends AuditField implements Serializable {
private static final long serialVersionUID = 8062436315663828938L;
#Schema(description = "Id merupakan primary key dan harus disertakan ketika edit, tipe datanya Long", example = "0", required = true)

#GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
#Schema(description = "kode kategori pengiriman", example = "BPSJCTH1", required = true)
#NotBlank(message = "Tidak Boleh Kosong")
private String categoryBPSCode;
#Schema(description = "nama kategori pengiriman", example = "Toko/Gudang Tujuan Tutup", required = true)
#NotBlank(message = "Tidak Boleh Kosong")
private String categoryBPSJName;
}
and here is my extended AuditField class :
#MappedSuperclass
#Data
#Audited
#EntityListeners(AuditingEntityListener.class)
#JsonIgnoreProperties(value = { "createdDate", "modifiedDate", "isDeleted" }, allowGetters = true, allowSetters = false)
public class AuditField implements Serializable {
private static final long serialVersionUID = 6025082509703710749L;
#Schema(description = "Status di hapus", example = "false", required = false)
public Boolean isDeleted = false;
#Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
public String reasonDeleted = "";
#CreatedDate
private Date createdDate;
#LastModifiedDate
private Date modifiedDate;
#CreatedBy
private String createdBy;
#LastModifiedBy
private String modifiedBy;
}
and here is my DTO AuditFieldDto class :
#Data
public class CategoryBpsjResponseDto extends AuditFieldDto implements Serializable {
private static final long serialVersionUID = -422185482845439241L;
#Schema(description = "Id merupakan primary key dan harus disertakan ketika edit, tipe datanya Long", example = "0", required = true)
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
public Long id;
#Schema(description = "kode kategori pengiriman", example = "BPSJCTH1", required = true)
#NotBlank(message = "Tidak Boleh Kosong")
public String categoryBPSCode;
#Schema(description = "nama kategori pengiriman", example = "Toko/Gudang Tujuan Tutup", required = true)
#NotBlank(message = "Tidak Boleh Kosong")
public String categoryBPSJName;
}
and here is my AuditFieldDto class :
#Data
public class AuditFieldDto implements Serializable {
private static final long serialVersionUID = 3758121148184815303L;
#Schema(description = "Status di hapus", example = "false", required = false)
public Boolean isDeleted = false;
#Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
public String reasonDeleted = "";
private String createdDate;
private String modifiedDate;
private String createdBy;
private String modifiedBy;
}
As you can see the AuditField and AuditFieldDto have the same field, but when i do run mvn clean package it give me COMPILATION ERROR like the top of my question mentioned. in the error message it seems to mapstruct cannot find the field properly. Then i try to remove #Mappings and #Mapping annotation line, the build is success. seems fishy.. because when i run with Boot Dashboard is working fine with those annotation.
here is my pom.xml :

What i missed in my project if i want to use #Mappings and #Mapping when i build my project to .jar files with mvn clean package?

i found the culprit here, but i am not sure why and is this the right things to do, since when i do this code, it worked. okay lets start, you can check my mapstruct version at my question, and here is how i fixed this :
first of all, in my AuditField and AuditFieldDto, as you can see i have 2 field that written in "public" data type, at first i write all of my field in public but then my friend come and refer me to make it private, but i accidentally i don't make all of it private, the two fields named public Boolean isDeleted; and public String reasonDeleted; is public, that's why the error go through them, they work fine and the error go to my another line that written in private.
and i just random miserably changed their data type back into public, as you can see there is 4 field that written in private fields, they are
#CreatedDate
private Date createdDate;
#LastModifiedDate
private Date modifiedDate;
#CreatedBy
private String createdBy;
#LastModifiedBy
private String modifiedBy;
so i changed all of them into public in my AuditFieldDto and AuditField class, the complete of code of my AuditField class is looked like this :
#MappedSuperclass
#Data
#Audited
#EntityListeners(AuditingEntityListener.class)
#JsonIgnoreProperties(value = { "createdDate", "modifiedDate", "isDeleted" }, allowGetters = true, allowSetters = false)
public class AuditField implements Serializable {
private static final long serialVersionUID = 6025082509703710749L;
#Schema(description = "Status di hapus", example = "false", required = false)
public Boolean isDeleted;
#Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
public String reasonDeleted;
#CreatedDate
public Date createdDate;
#LastModifiedDate
public Date modifiedDate;
#CreatedBy
public String createdBy;
#LastModifiedBy
public String modifiedBy;
}
it's apply the same for my AuditFieldDto class, which is looked like this :
#Data
public class AuditFieldDto implements Serializable {
private static final long serialVersionUID = 3758121148184815303L;
#Schema(description = "Status di hapus", example = "false", required = false)
public Boolean isDeleted = false;
#Schema(description = "Alasan di hapus", example = "apa pun alasannya", required = false)
public String reasonDeleted = "";
public String createdDate;
public String modifiedDate;
public String createdBy;
public String modifiedBy;
}
and when i do run mvn clean package the build is a success! and i ran the .jar files, it working! i guess why??? i stuck for days because of this. then i try to look into the generated files, you can find the generated files in your project located at target/generated-sources/annotations and fine the mapper class file. And here is mine, i only take one example of the generated code, since the other seems doesn't have any problem.
here is what inside the GENERATED FILE (we shouldn't edit this file, just for view) :
#Component
public class ICategoryBpsjMapperImpl implements ICategoryBpsjMapper {
#Override
public CategoryBpsjResponseDto entityToDto(CategoryBPSJ entity) {
if ( entity == null ) {
return null;
}
CategoryBpsjResponseDto categoryBpsjResponseDto = new CategoryBpsjResponseDto();
if ( entity.createdDate != null ) {
categoryBpsjResponseDto.createdDate = new SimpleDateFormat( "dd-MM-yyyy HH:mm:ss" ).format( entity.createdDate );
}
if ( entity.modifiedDate != null ) {
categoryBpsjResponseDto.modifiedDate = new SimpleDateFormat( "dd-MM-yyyy HH:mm:ss" ).format( entity.modifiedDate );
}
categoryBpsjResponseDto.isDeleted = entity.isDeleted;
categoryBpsjResponseDto.reasonDeleted = entity.reasonDeleted;
categoryBpsjResponseDto.createdBy = entity.createdBy;
categoryBpsjResponseDto.modifiedBy = entity.modifiedBy;
return categoryBpsjResponseDto;
}
}
you see they access the property without get and set (i mean getter setter), i think this is the culprit that cause my error since when i marked the field as private, and if the code is written like that, they won't can be accessed. for now this is the way i solved it.
if someone have better answer, i will take their answer as accepted answer, if mine code not right or appropriate, waiting for it.

I think you're missing the lombok-mapstruct-binding.

#EnableJpaRepositories is not present in spring boot 2.1.4.RELEASE

I created a project using spring boot 2.1.4.RELEASE with the following dependencies:
<dependencies>
<dependency>
<groupId>com.h2database</groupId>
<artifactId>h2</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
</dependencies>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.1.4.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
I have the following entity and repository:
#Entity
public class Person {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#Column(name = "name")
private String name;
#Column(name = "last_name")
private String lastName;
#Column(name = "age")
private Integer age;
#Column(name = "createdAt")
#Temporal(TemporalType.TIMESTAMP)
private Date createdAt;
...
}
PersonRepository.java
#Repository
public interface PersonRepository extends CrudRepository<Person, Integer> {
}
The following is my Application class:
#SpringBootApplication
public class SpringDataApplication {
public static void main(String[] args) throws Exception {
ConfigurableApplicationContext context = SpringApplication.run(SpringDataApplication.class, args);
PersonRepository personRepository = context.getBean(PersonRepository.class);
Person p1 = new Person("Juan", "Camaney", 55);
Person p2 = new Person("Arturo", "Lopez", 33);
Person p3 = new Person("Pancho", "Coscorin", 22);
personRepository.save(p1);
personRepository.save(p2);
personRepository.save(p3);
Iterator<Person> people = personRepository.findAll().iterator();
while (people.hasNext()) {
Person temp = people.next();
System.out.println(temp);
}
}
}
If i execute my application i get the following error:
Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.devs4j.spring.data.repositories.PersonRepository' available
The solution of it is add the following configuration class:
#Configuration
#EnableJpaRepositories("com.devs4j.spring.data.repositories")
public class JpaConfiguration {
}
But I get the error :
EnableJpaRepositories cannot be resolved to a type
If i downgrade to 2.0.5.RELEASE everything works fine.
I'm confused because when i check the following spring documentation https://docs.spring.io/spring-data/jpa/docs/2.1.6.RELEASE/reference/html/ I see that it is still using #EnableJpaRepositories("com.acme.repositories")
Am i doing something wrong ?

In your configuration.java, have you added the import:
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

Error executing DDL via JDBC Statement in Spring-MVC project

I'm trying to run my Java Spring MVC project application, but I get the following error (I have connectted my MySql database to the project):
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement
which is caused by:
Caused by: java.sql.SQLException: Cannot add foreign key constraint
The foreign key problem above is about the "OrderItems" Entity in my database, here is its code:
package com.example.WebAppProcess20.Entities;
import javax.persistence.*;
import java.util.Objects;
#Entity
#Table(name = "ordersitems", schema = "theprocess")
#IdClass(OrdersitemsEntityPK.class)
public class OrdersitemsEntity {
private String orderId;
private String productId;
private Integer qunatity;
private OrdersEntity ordersByOrderId;
#Id
#Column(name = "orderId")
public String getOrderId() {
return orderId;
}
public void setOrderId(String orderId) {
this.orderId = orderId;
}
#Id
#Column(name = "product_id")
public String getProductId() {
return productId;
}
public void setProductId(String productId) {
this.productId = productId;
}
#Basic
#Column(name = "qunatity")
public Integer getQunatity() {
return qunatity;
}
public void setQunatity(Integer qunatity) {
this.qunatity = qunatity;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
OrdersitemsEntity that = (OrdersitemsEntity) o;
return Objects.equals(orderId, that.orderId) &&
Objects.equals(productId, that.productId) &&
Objects.equals(qunatity, that.qunatity);
}
#Override
public int hashCode() {
return Objects.hash(orderId, productId, qunatity);
}
#ManyToOne
#JoinColumn(name = "orderId", referencedColumnName = "orderId", nullable = false, updatable = false, insertable = false)
public OrdersEntity getOrdersByOrderId() {
return ordersByOrderId;
}
public void setOrdersByOrderId(OrdersEntity ordersByOrderId) {
this.ordersByOrderId = ordersByOrderId;
}
}
This Entity specifies the products included in each order, therefore it has two foreign keys - productId and OrderId.
also adding the pom.xml and hibernate.cfg.xml files if necessary:
hibernate.cfg.xml:
<?xml version='1.0' encoding='utf-8'?>
