我编写了自己的SpringSecurity UserDetailsService。我使用了this教程。 我的配置与该教程之间的唯一区别是，我有一个用于spring框架的xml文件。但我的申请不起作用：
问题是，userDao.load(email);（在下面观察UserDetailsService）返回null而不是userObject。但是，如果我将SpringSecurity的配置切换到inMemoryAuthentication并在另一个上下文中使用userDao.load(email);，该服务将返回正确的用户。
堆栈跟踪：

您需要启用事务管理支持。在您使用的指南中，通过AppConfig类上的@EnableTransactionManagement注释完成了它。在您的情况下，您使用xml配置，因此您应该在spring-config.xml
中添加<tx:annotation-driven transaction-manager="txManager" />
