Hello all.
PLease help me understand me what is wrong.
I use auto generated entity from mysql db by spring-tool-suite->eclipselink with DALI installed
For tables with compound key it generate embedded class and use it as a key
@Entity
@NamedQuery(name="Customer.findAll", query="SELECT c FROM Customer c")
public class Customer implements Serializable {
private static final long serialVersionUID = 1L;
@EmbeddedId
private CustomerPK id;
also I use EclipseLinkJpaVendorAdapter for LocalContainerEntityManagerFactoryBean
and when factory begin generating repository for this entity,
at the moment
@Autowired
CustomerRepository customerRepository;
I got an error
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scanner': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: home.abel.PhotoHub.Domain.CustomerRepository home.abel.PhotoScan.fileScanner.customerRepository; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customerRepository': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalArgumentException: Expected id attribute type [class home.abel.PhotoHub.Domain.CustomerPK] on the existing id attribute [SingularAttributeImpl[EntityTypeImpl@768981123:Department [ javaType: class home.abel.PhotoHub.Domain.Department descriptor: RelationalDescriptor(home.abel.PhotoHub.Domain.Department --> [DatabaseTable(DEPARTMENT)]), mappings: 3],org.eclipse.persistence.mappings.ManyToOneMapping[department]]] on the identifiable type [EntityTypeImpl@92917455:Customer [ javaType: class home.abel.PhotoHub.Domain.Customer descriptor: RelationalDescriptor(home.abel.PhotoHub.Domain.Customer --> [DatabaseTable(CUSTOMER)]), mappings: 3]] but found attribute type [class home.abel.PhotoHub.Domain.Department].
But when i remove compound key class, and use single variable like
@Entity
@NamedQuery(name="Customer.findAll", query="SELECT c FROM Customer c")
public class Customer implements Serializable {
private static final long serialVersionUID = 1L;
@id
private String id;
It work good.
Here is my simple code for check this situationsituation
Customet.java
@Entity
@NamedQuery(name="Customer.findAll", query="SELECT c FROM Customer c")
public class Customer implements Serializable {
private static final long serialVersionUID = 1L;
@EmbeddedId
private CustomerPK id;
//bi-directional many-to-one association to Department
@ManyToOne
private Department department;
public Customer() {
}
public CustomerPK getId() {
return this.id;
}
public void setId(CustomerPK id) {
this.id = id;
}
public Department getDepartment() {
return this.department;
}
public void setDepartment(Department department) {
this.department = department;
}
}
-------------- CustomerPK.java ------------
@Embeddable
public class CustomerPK implements Serializable {
//default serial version id, required for serializable classes.
private static final long serialVersionUID = 1L;
private String id;
@Column(name="department_id", insertable=false, updatable=false)
private String departmentId;
. . .
}
Department.java
@Entity
@NamedQuery(name="Department.findAll", query="SELECT d FROM Department d")
public class Department implements Serializable {
private static final long serialVersionUID = 1L;
@Id
private String id;
. . .
}
CustomerRepository.java
import org.springframework.data.repository.CrudRepository;
public interface CustomerRepository extends CrudRepository<Customer, CustomerPK> {
}
fileScanner.java
public class fileScanner {
@Autowired
CustomerRepository customerRepository;
. . .
}
Spring config
@Configuration
@ComponentScan
@EnableJpaRepositories
@EnableTransactionManagement
public class Config {
@Bean
EclipseLinkJpaVendorAdapter vendorAdapter() {

va.setShowSql(true);
va.setDatabasePlatform("org.eclipse.persistence.platform.database.MySQLPlatform");
va.setGenerateDdl(false);
va.setDatabase(Database.MYSQL);
return va;
}
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
Map<String, String> jpaProperties = new HashMap<String, String>();
jpaProperties.put("eclipselink.weaving", "static");
factory.setJpaPropertyMap(jpaProperties);
factory.setJpaVendorAdapter(vendorAdapter());
factory.setJpaDialect(new EclipseLinkJpaDialect());
factory.setPackagesToScan("home.abel.PhotoHub.Domain");
factory.setDataSource(dataSource());
return factory;
}
@Bean
public PlatformTransactionManager transactionManager() {
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory(entityManagerFactory().getObject());
return txManager;
