我一直在努力让@AuthenticationPrincipal与自定义User类一起正常工作.不幸的是,用户始终为空.这是代码:

调节器

@RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView index(@AuthenticationPrincipal User user) {
    ModelAndView mav= new ModelAndView("/web/index");
    mav.addObject("user", user);
    return mav;
}

安全配置

@Configuration
@EnableWebMvcSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    CustomUserDetailsService customUserDetailsService;

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
            auth.userDetailsService(customUserDetailsService).passwordEncoder(passwordEncoder());
    }

}

CustomUserDetailsS​​ervice

@Component
public class CustomUserDetailsService implements UserDetailsService {

@Autowired
UserRepository userRepository;

@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
    // Spring Data findByXY function
    return userRepository.findByUsername(username);
}

用户实体

public class User implements UserDetails{
    private …

问题: 我想从authenticate.getName()中获取/提取用户名/电子邮件...如果可能,不要使用解析字符串.

authentication.getName()或principal.getName()值:

[username]: org.springframework.security.core.userdetails.User@21463e7a: Username: butitoy@iyotbihagay.com; Password: [PROTECTED]; Enabled: true; AccountNonExpired: true; credentialsNonExpired: true; AccountNonLocked: true; Not granted any authorities

在这个例子中,我只想获得Username的值,即butitoy@iyotbihagay.com

解:

由于我只想获得用户名/电子邮件(butitoy@iyotbihagay.com),并且它返回了整个主要内容/文本(上图),我将主题中设置的值从主要值...替换为电子邮件价值..它现在有效.

    AuthenticatedUser loginUser = new AuthenticatedUser(email);
    loginUser.setToken(token);
    String jsonUser = Util.objectToJsonResponseAsString(loginUser, "user");
    res.addHeader(SecurityConstants.HEADER_STRING, SecurityConstants.TOKEN_PREFIX …
