org.hibernate.PersistentObjectException : 메모리 데이터베이스에 H2로 지속되도록 전달 된 분리 된 엔티티

나는 테스트를 위해 메모리 데이터베이스에 H2를 사용하고 있으며 구성은 다음과 같습니다.

1- SpringTestingConfig :

@Configuration
@ComponentScan(basePackages = "com.myapp.data", excludeFilters = { @Filter(Configuration.class) })
@PropertySource("classpath:/test.properties")
@Profile("test")
public class SpringTestingConfig {
   @Bean
   public DataSource dataSource() {
      DriverManagerDataSource dataSource = new DriverManagerDataSource();
      dataSource.setDriverClassName("org.h2.Driver");
      dataSource.setUrl("jdbc:h2:mem:test;MODE=Mysql;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS MYAPP");
      dataSource.setUsername("sa");
      dataSource.setPassword("");
      return dataSource;
   }
}

2 - MyTestClass :

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({ WebContextTestExecutionListener.class,
        DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class })
@ActiveProfiles("test")
@DirtiesContext
@ContextConfiguration(loader = AnnotationConfigContextLoader.class, classes = {
        SpringConfig.class, SpringTestingConfig.class,
        SpringLocalContainerJPAConfig.class, CustomConfiguration.class })
@PrepareForTest({ FacesContext.class })
@PowerMockIgnore({ "javax.management.*", "javax.xml.parsers.*",
    "com.sun.org.apache.xerces.internal.jaxp.*", "ch.qos.logback.*",
    "org.slf4j.*" })
public class MyTestClass{

   private Company company;
   private User user;


   @Test
    public void signup(){

       User user = new User();
    Company company = new Company();
    company.setName("Test");
    company = usService.saveCompany(company);
    user.setFirstName("Test");
    user.setLastName("User");
    user.setEmail("test@test.com");
    user.setPassword("verySecret");
    user.setCompany(company);
    user = usService.saveUser(user); // gives exception

   }

}

3- 방법 저장 :

@Transactional(propagation = Propagation.REQUIRED)
    public User saveUser(User user) {
        return userRepository.saveAndFlush(user); //JpaRepository
    }

@Transactional(propagation = Propagation.REQUIRED)
    public Company saveCompany(Company company) {
        return companyRepository.saveAndFlush(company); //JpaRepository
    }

4- JPA 구성

  Properties jpaProperties = getHibernateProperties();
  jpaProperties.put(HIBERNATE_TRANSACTION_JTA_PLATFORM, SpringJtaPlatform.class.getName().toString());
  bean.setJpaProperties(jpaProperties);

  puManager.afterPropertiesSet();
  bean.afterPropertiesSet();
  return bean.getObject();
}

protected String getDefaultSchema() {
  String ds = ConfigurationUtil.config().getString("db.schema.name");
  if (ds != null) defaultSchema = ds;
  return defaultSchema;

  return showSql;
}

protected String getUseSqlComments() {
  return useSqlComments;
}

protected String packagesToScan() {
      return packagesToScan;
   }

@Bean
protected JtaTransactionManager transactionManager() {
  SpringBeanFactory.setApplicationContext(applicationContext);
  JtaTransactionManager manager = new JtaTransactionManager();
  manager.setTransactionManagerName("java:jboss/TransactionManager");
  manager.setUserTransactionName("java:jboss/UserTransaction");
  manager.afterPropertiesSet();
  return manager;
}

}

5- 사용자 엔티티 :

@Entity
@Table(name = "User", uniqueConstraints = { @UniqueConstraint(columnNames = {
        "CompanyGID", "MPath" }) })
public class User extends PersistableEntity implements UserDetails {
    /**
     * 
     */
    private static final long serialVersionUID = -6520416613985790209L;

    @ManyToOne(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
    @JoinColumn(name = "CompanyGID")
    private Company company;

문제 : Jboss에서 응용 프로그램 (로컬 데이터베이스)을 실행하고 bean bean 메소드에서 코드를 호출 할 때 테스트 메소드의 코드는 매우 잘 작동하지만 테스트 (메모리 데이터베이스)에서 실행하면 회사를 저장하고 사용자를 저장하려고 할 때 예외를 준다 :

해결법

==============================

1.나는이 문제가 여기 있다고 생각한다.

나는이 문제가 여기 있다고 생각한다.

 @Test
    public void signup(){

    User user = new User();
    Company company = new Company();
    company.setName("Test");
    company = usService.saveCompany(company); //object is saved and transaction is closed, so company is detached here. 
    user.setFirstName("Test");
    user.setLastName("User");
    user.setEmail("test@test.com");
    user.setPassword("verySecret");
    user.setCompany(company); //u are setting this detached object to user, NOTE user object's company attr is cascade.all which means this company will be saved as well when you save user. 
    user = usService.saveUser(user); // gives exception, because you are saving new user object with detached company object. 

   }

어떻게 해결할 수 있을까요? 사용자가 회사 개체를 저장하도록 할 수 있으므로 명시 적으로 회사를 저장하지 않습니다. cascade.all이 사용자의 회사 개체에 대해 사용 중이므로 사용자가 저장 될 때 회사도 저장해야합니다.

@Test
    public void signup(){

    User user = new User();
    Company company = new Company();
    company.setName("Test");
    user.setFirstName("Test");
    user.setLastName("User");
    user.setEmail("test@test.com");
    user.setPassword("verySecret");
    user.setCompany(company);
    user = usService.saveUser(user); // gives exception

   }
