我有一个集成测试在子实体上执行删除操作，但是在日志中看不到delete语句，当然测试失败。
日志说：

测试本身不是交易性的：
@Test
public void testDeleteByUserRoleId() {
UserRole loadedUserRole = userRoleRepository.findOne(userRole0.getId());
assertNotNull(loadedUserRole);
loadedUserRole = userRoleRepository.deleteById(userRole0.getId());
UserRole myloadedUserRole = userRoleRepository.findOne(userRole0.getId());
assertNull(myloadedUserRole);
}
域名是：

如果我将它与一个非常相似的集成测试进行比较，这个删除用户实体而不是用户角色，日志显示它正在调用delete语句：

请注意，deleteById方法是事务性的，并且由用户和用户角色删除集成测试使用：
@Override
@Transactional
public T deleteById(ID id) throws EntityNotFoundException {
T entity = findOne(id);
if (entity != null) {
delete(entity);
} else {
throw new EntityNotFoundException("The entity could not be found and was not deleted");
}
return entity;
}

在删除陈述
后添加entityManager.flush()
@PersistenceContext
EntityManager em;
@Test
public void testDeleteByUserRoleId() {
UserRole loadedUserRole = userRoleRepository.findOne(userRole0.getId());
assertNotNull(loadedUserRole);
loadedUserRole = userRoleRepository.deleteById(userRole0.getId());
em.flush();
UserRole myloadedUserRole = userRoleRepository.findOne(userRole0.getId());
assertNull(myloadedUserRole);
}
答案 1 :(得分：0)
这并不是真正的解决方案，而是更多有关此问题的更新。
将项目升级到Spring Boot 2 2.0.3.RELEASE并使用assertEquals(Optional.empty(),myloadedUserRole);后，测试成功通过。
@Test
public void testDeleteById() {
Optional<UserRole> loadedUserRole = userRoleRepository.findById(userRole0.getId());
assertNotNull(loadedUserRole.get());
UserRole deletedUserRole = userRoleRepository.deleteByUserRoleId(userRole0.getId());
Optional<UserRole> myloadedUserRole = userRoleRepository.findById(userRole0.getId());
assertEquals(Optional.empty(),myloadedUserRole);
}
