역할 (기존) 역할이있는 사용자 개체가 삽입됩니다. 이 user_role.id 나에게없는 삽입 널 (null)을주고있다ORA-01400 : @manytomany unidierctional에 NULL을 삽입 할 수 없습니다.
스키마 : 이제

나는 그것이 나에게 예외 java.sql.SQLIntegrityConstraintViolationException: ORA-01400: cannot insert NULL into ("USER_ROLE"."ID")
사용자를 생성하려면 아래와 같이 스프링 저장소 코드를 사용합니다.
@Override
@Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
public User createUser(User user) throws BusinessException {
List<Error> errors = new ArrayList<Error>();
validateUserRoles(user ,errors);
if (errors.size() > 0)
{
throw new BusinessException(errors);
}
user.setUserIdentifier(user.getUserIdentifier().trim());
logger.info("Creating User with username: " + user.getUserIdentifier());
return this.userRepositotry.save(user);
}
private void validateUserRoles(User user ,List<Error> errors) {
Set<Role> roles = new HashSet<Role>();
if (user.getRoles() != null)
{
for(Role role : user.getRoles())
{
Role r = null;
if(role.getId() != null)
{
r = this.roleRepository.findOne(role.getId());
} else if(role.getName() != null)
{
r = this.roleRepository.findByName(role.getName());
}
if(r == null)
{
errors.add(new Error(ErrorCode.INVALID_ARGUMENTS,"Invalid user Role.",r));
} else
{
roles.add(r);
}
}
}
user.setRoles(roles);
}
