我已经被这个问题困扰了一段时间，我需要你的帮助。我会尽量提供尽可能多的细节，并会根据需要进行编辑。
我正在尝试在 Spring 安全性的自定义 UserDetailsService 中的数据库中创建用户。场景是：当用户登录我的应用程序时，如果用户存在，我会检查我的数据库；如果不存在，我会调用 Web 服务来检查该用户是否存在并导入他的所有信息，以便将它们保存到我自己的数据库中并授予他对 Web 应用程序的访问权限。
我可以从数据库中读取信息（SELECT 查询），但是如果没有得到以下（美丽的）错误，我就无法进行任何插入：
org.springframework.security.authentication.AuthenticationServiceException: Could not commit JPA transaction; nested exception is javax.persistence.RollbackException: Error while committing the transaction
org.springframework.security.authentication.dao.DaoAuthenticationProvider.retrieveUser(DaoAuthenticationProvider.java:85)
在应用程序的其他部分（一旦经过身份验证），我可以使用来自控制器的任何服务。插入+选择工作正常。
关于我的配置，我有以下文件： spring security config (Spring security context) is in "applicationContext-security.xml" spring beans (Root Context) in "applicationContext.xml" spring mvc (DispatcherServlet) in webmvc-config.xml和一个 applicationContext-jpa.xml + persistence.xml
UserDetailsService 的实现：
@Transactional(propagation = Propagation.REQUIRES_NEW)
public class CustomUserDetailsService implements UserDetailsService {
@PersistenceContext
private EntityManager em;
[...Other Declarations...]
@Autowired
private userService userService;
@Override
public UserDetails loadUserByUsername(String login) throws UsernameNotFoundException {
User user = null; //extends spring security UserDetails
//If I try to find existing users in database here, it works perfectly
User user = userService.findUserByLogin(login);
List<GrantedAuthority> authorities = ...
Set<String> permissions = ...
if(user == null){
//Call webservice and get User if exists => newUser
//Save in user table
userService.saveUser(newUser);
//No error here, I can even try a userService.findUser(newUser.getId()); and I get the results. the commit is after returning the UserDetails from this method.
//I also tried the following solution... the entitymanager is well Autowired and I can access everything as usual
// em.getTransaction().begin(); // => Throw here 'nested exception is java.lang.IllegalStateException: Not allowed to create transaction on shared EntityManager - use Spring transactions or EJB CMT instead'
// em.persist(operator);
// em.getTransaction().commit();
// em.close();
user = newUser
}
else{
//Other things
}
}
return user; //if I tried a saveUser, commit is done after the return and the exception is thrown
}
}
我在类和方法本身上尝试了 @Transactional 的所有组合。
现在所有的配置文件[只有配置文件的有用部分]

我的事务管理器处于模式 =“aspectj”（我试过没有它，代理）我的所有 Aspectj 库都运行良好。加载时编织等等。我还在我的应用程序中使用 *.aj 文件。我还尝试在我的 customUserDetailsService 类上添加一个 aop:advisor
applicationContext-security.xml：

</beans:beans>
applicationContext-jpa.xml 只有基本的存储库声明：
<beans:beans xmlns:beans="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/data/jpa"

<repositories base-package="com.company.myApp.common.repository" />
</beans>
webmvc-config 有 context:component-scan 用于控制器和其他仅适用于 webapp 的东西。with<aop:aspectj-autoproxy/>和其他 aop:advisors。
