我使用，
我使用的地方，
org.springframework.security.authentication.dao.DaoAuthenticationProvider
用于身份验证。我的spring-security.xml文件如下所示。

UserDetailsService的实现如下。
@Service(value="userDetailsService")
public final class UserDetailsImpl implements UserDetailsService {
@Autowired
private final transient UserService userService = null;
@Autowired
private final transient AssemblerService assemblerService = null;
@Override
@Transactional(readOnly = true, propagation = Propagation.REQUIRED)
public UserDetails loadUserByUsername(String userName) throws UsernameNotFoundException {
UserTable userTable = userService.findUserByName(userName);
if (userTable == null) {
throw new UsernameNotFoundException("User name not found.");
} else if (!userTable.getEnabled()) {
throw new DisabledException("The user is disabled.");
} else if (!userTable.getVarified()) {
throw new LockedException("The user is locked.");
}
//Password expiration and other things may also be implemented as and when required.
return assemblerService.buildUserFromUserEntity(userTable);
}
}
并且以下只是帮助服务，该服务将转换将由Spring User对象使用的用户实体。
@Service(value="assembler")
@Transactional(readOnly = true, propagation=Propagation.REQUIRED)
public final class AssemblerDAO implements AssemblerService {
@Override
public User buildUserFromUserEntity(UserTable userTable) {
String username = userTable.getEmailId();
String password = userTable.getPassword();
boolean active = userTable.getEnabled();
boolean enabled = active;
boolean accountNonExpired = active;
boolean credentialsNonExpired = active;
boolean accountNonLocked = userTable.getVarified();
Collection<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
for (UserRoles role : userTable.getUserRolesSet()) {
authorities.add(new SimpleGrantedAuthority(role.getAuthority()));
}
return new User(username, password, enabled, accountNonExpired, credentialsNonExpired, accountNonLocked, authorities);
}
}
没有必要引用这些类。
我的问题是使用时，
org.springframework.security.provisioning.JdbcUserDetailsManager
[UserDetailsManager可以注入控制器及其
public void changePassword(String oldPassword, String newPassword) throws AuthenticationException {
//...
}
方法可用于更改密码。我从没有尝试过，但是可以像下面这样大致实现。
<bean id="jdbcUserService" class="org.springframework.security.provisioning.JdbcUserDetailsManager">
<property name="dataSource" ref="datasource" />
<property name="authenticationManager" ref="authenticationManager" />
</bean>
并且在控制器中，应按如下所示进行注入。
@Autowired
@Qualifier("jdbcUserService")
public UserDetailsManager userDetailsManager;
Spring安全提供了我正在使用的方法中的任何功能，还是仅是我自己在DAO中使用的简单方法来更改当前登录用户的密码就足够了？请建议，如果我在任何地方做错了！
此内容可能太大，无法回答这个问题，但我问这个是因为这是完全实验性的。
更改密码的方法是一个很好的解决方案，因为在Spring Security中没有特殊的功能。
Spring安全中为此没有特殊功能的原因是，如果使用会话，则不需要它。
我同意@jhadesdev的回答；
