Базовый DAO имеет метод
</p>
<pre><code>public void create(M model) throws DAOException {
try {
entityManager.persist(model);
} catch (RollbackException rollBackExp) {
ErrorCode errorCode = new ErrorCode();
// SQLException sqle = (SQLException) pExp.getCause().getCause();
// errorCode = errorHandler.getErrorCode(sqle);
// errorCode.setCode(sqle.getErrorCode() + "");
throw new DAOException(errorCode, rollBackExp);
} catch (PersistenceException pExp) {
ErrorCode errorCode = new ErrorCode();
// SQLException sqle = (SQLException) pExp.getCause().getCause();
// errorCode = errorHandler.getErrorCode(sqle);
// errorCode.setCode(sqle.getErrorCode() + "");
throw new DAOException(errorCode, pExp);
}finally{
entityManager.flush();
}
}
, и сервисы просто делегируют его dao, а пока обернуты в транзакцию к весне.когда я запускаю свой тест для сохранения пользователя, только он работает нормально, но когда я добавляю userRoles для пользователя
</p>
<pre><code> if(roles.size() == 0){
Role arole = initRole(RoleType.ADMIN.name(),
CREATION_DATE_YESTERDAY, MODIFICATION_DATE_TODAY);
Role srole = initRole(RoleType.SUPER_USER.name(),
CREATION_DATE_YESTERDAY, MODIFICATION_DATE_TODAY);
Role urole = initRole(RoleType.USER.name(),
CREATION_DATE_YESTERDAY, MODIFICATION_DATE_TODAY);
roles.put(arole.getRoleName(), arole);
roles.put(srole.getRoleName(), srole);
roles.put(urole.getRoleName(), urole);
}
User user_one = initUser("user" + (i+1) , "user" + (i+1), "user" + (i+1) + "@user.com",
CREATION_DATE_YESTERDAY, MODIFICATION_DATE_TODAY);
user_one.setUserRoles(new HashSet<Role>(roles.values()));
Enumeration<String> roleKeys = roles.keys();
while(roleKeys.hasMoreElements()){
String key = roleKeys.nextElement();
Role role = roles.get(key);
role.setUser(user_one);
}
try {
userService.create(user_one);
Set<Role> urole = user_one.getUserRoles();
for (Role role : urole) {
roles.put(role.getRoleName(), role);
}
//logger.debug(user_one);
} catch (ServiceException e) {
e.printStackTrace();
}
Это вызывает исключение в секундуитерация
java.sql.BatchUpdateException: Duplicate entry '3' for key 'ROLE_ID'
ERROR: org.hibernate.util.JDBCExceptionReporter - Duplicate entry '3' for key 'ROLE_ID'

Может кто-нибудь подсказать, что не так с этим битом кода.
Невозможно использовать аннотации, поскольку это отображение используемого старого кодав различных приложениях
