试图对用户进行身份验证时发生内部错误

Question

我已经创建了UserDetailsServiceImpl。在这里我得到了这个用户的用户名和角色。但我不明白问题出在哪里。我已经在数据库中尝试了sql查询。

securityconfig.java

@EnableWebSecurity
@ComponentScan("com")
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Autowired
private UserDetailsService userDetailsService;

@Bean
public BCryptPasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder();
};

@Autowired
protected void configureGlobalSecurity(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder());
}


@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests().antMatchers("/login", "/", "/veteriner").permitAll().antMatchers("/**")
            .hasRole("ADMIN").and().formLogin().loginPage("/login").defaultSuccessUrl("/login/login-status-success")
            .failureUrl("/login/login-status-error").permitAll().usernameParameter("username")
            .passwordParameter("password").and().logout().logoutSuccessUrl("/logout-success")
            .invalidateHttpSession(true).permitAll().and().csrf();
}

LoginController.java

 @Controller
 @RequestMapping(value = "/login", method = RequestMethod.GET)
 public class LoginController {

 @GetMapping
 public ModelAndView home() throws Exception {
    ModelAndView mv = new ModelAndView();
    mv.setViewName("login");
    return mv;
}

@RequestMapping(path="/login-status-error",method = RequestMethod.GET)
@ResponseBody
public ModelAndView erorLogin() throws Exception {
    ModelAndView mv = new ModelAndView();
    mv.setViewName("main");
    return mv;
}

@RequestMapping(path="/login-status-succes",method = RequestMethod.GET)
@ResponseBody
public ModelAndView succesLogin() throws Exception {
    ModelAndView mv = new ModelAndView();
    mv.setViewName("veteriner");
    return mv;
}

}

@Service("userDetailsService")
public class UserDetailsServiceImpl implements UserDetailsService {

@Autowired
private UserService userService;

@Transactional(readOnly = true)
@Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {

    com.model.User user = userService.findByUsername(username);
    if (user == null) {
        throw new UsernameNotFoundException("User not found.");
    }

    User securityUser = new User(user.getUsername(), user.getPassword(), true, true, true, true,
            buildUserAuthority(user.getUserRoles()));
    return securityUser;
}

private List<GrantedAuthority> buildUserAuthority(List<User_role> userRoles) {
    Set<GrantedAuthority> setAuths = new HashSet<GrantedAuthority>();

    for (User_role userRole : userRoles) {
        setAuths.add(new SimpleGrantedAuthority(userRole.getRole().getRoleName()));
    }

    List<GrantedAuthority> results = new ArrayList<GrantedAuthority>(setAuths);
    return results;
}

有太多的事情让我无法理解，但我认为这是一个简单的情况，您不能同时在同一个类中创建和注入同一个bean。

即。

@Configuration
public class SecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public UserDetailsService userDetailsService() {...}
}

行不通。想想看，您需要UserDetailsService来创建应该创建UserDetailsService的类。那怎么行？

您可以改为这样做：

@EnableWebSecurity
@ComponentScan("com")
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Bean
    public UserDetailsService userDetailsService() {
        return super.userDetailsService();
    }

    @Bean
    public DaoAuthenticationProvider getDaoAuthenticationProvider() {
        DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();
        //call the userDetailsService() method here
        authProvider.setUserDetailsService(userDetailsService());
        authProvider.setPasswordEncoder(this.passwordEncoder());
        return authProvider;
    }

    ...

}

虽然这看起来很奇怪，但它做了正确的事情。Spring代理所有方法调用，所以当您看似直接调用userdetailsservice()时，实际上它会注入适当的bean。
