环境:

• 春季4.1.6
• Spring Security 4.0.1

我有2个身份验证提供程序 - 一个访问ActiveDirectory,然后一个命中我创建的自定义数据库提供程序.以这些环境中的任何一个用户身份登录都可以完美地运行.用户已通过身份验证,应用程序仍在继续.

但是,当输入无效用户且两个提供程序都无法进行身份验证时,我在页面上收到此异常:

java.lang.StackOverflowError
    org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter$UserDetailsServiceDelegator.loadUserByUsername(WebSecurityConfigurerAdapter.java:393)
    org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter$UserDetailsServiceDelegator.loadUserByUsername(WebSecurityConfigurerAdapter.java:394)
    org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter$UserDetailsServiceDelegator.loadUserByUsername(WebSecurityConfigurerAdapter.java:394)
    org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter$UserDetailsServiceDelegator.loadUserByUsername(WebSecurityConfigurerAdapter.java:394)

这是我的WebSecurityConfigurerAdapter配置:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http
            .csrf().disable()
            .formLogin().loginPage("/login").failureUrl("/login?error").defaultSuccessUrl("/overview").permitAll()
            .and()
                .logout().logoutSuccessUrl("/login?logout").permitAll()
            .and()
                .authorizeRequests()
                .antMatchers("/resources/**").permitAll()
                .antMatchers("/favicon.ico").permitAll()
                .antMatchers("/**").hasRole("AUTH");
}

@Override
protected void configure(AuthenticationManagerBuilder authManagerBuilder) throws Exception {
    authManagerBuilder
            .authenticationProvider(activeDirectoryLdapAuthenticationProvider())
            .userDetailsService(userDetailsService());

    authManagerBuilder
            .authenticationProvider(databaseAuthenticationProvider())
            .userDetailsService(userDetailsService());
}

@Bean
public ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
    ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider(DOMAIN, URL);
    provider.setConvertSubErrorCodesToExceptions(true);
    provider.setUseAuthenticationRequestCredentials(true);
    provider.setUserDetailsContextMapper(userDetailsContextMapper());
    return provider;
}

@Bean
public UserDetailsContextMapper userDetailsContextMapper() {
    UserDetailsContextMapper contextMapper = new MyUserDetailsContextMapper();
    return contextMapper;
}

@Bean …

我有一些Spring安全身份验证问题.在我的应用程序中,一切都很好(CRUD操作运行良好),但登录尝试失败.

这是我的代码(我在下面标注了注释,其中userDAO为null,这是验证失败的原因):

@Service
public class UserServiceImpl implements UserService, UserDetailsService {

    @Autowired
    UserDAO userDAO;

    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userDAO.getUserByUsername(username); //userDAO == null Causing NPE
        if (user == null)
            throw new UsernameNotFoundException("Oops!");

        List<SimpleGrantedAuthority> authorities = Arrays.asList(new SimpleGrantedAuthority(user.getRole()));

        return new org.springframework.security.core.userdetails
                .User(user.getLogin(), user.getPassword(), authorities);
    }

@Override
    public List<User> getUsers() {
        return userDAO.getUsers();//userDAO !=null
    }
//rest of code skipped

我的SecurityConfig看起来像这样

@Configuration
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

 UserServiceImpl userService = new UserServiceImpl();

    @Override …
