我正在尝试在 Spring 中使用 SwitchUserFilter 实现模拟，但出现错误。没有这个实现，项目运行良好。此外，该项目使用的是 Java 注释而不是 xml 配置，并且具有 SecureAuth 身份验证。而进入SecurityConfig类的代码涉及到的部分是:

@Configuration
@ComponentScan(basePackages = {"com.project.*"})
@EnableWebMvcSecurity
@EnableGlobalMethodSecurity(securedEnabled = true)
@PropertySource("classpath:app.properties")
@Import({TransactionManagersConfig.class, MailConfig.class})
public class SecurityConfig extends WebSecurityConfigurerAdapter {

  @Autowired
  private SwitchUserFilter switchUserFilter;

  @Autowired
  protected AuthenticationSuccessHandler authenticationSuccessHandler;

  @Bean
  public UserDetailsService userDetailsServiceBean() {
    try {
        return super.userDetailsServiceBean();
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
  }

  @Bean
  public SwitchUserFilter switchUserFilter() {
    SwitchUserFilter switchUserFilter = new SwitchUserFilter();
    switchUserFilter.setUserDetailsService(userDetailsServiceBean());
    switchUserFilter.setUsernameParameter("username");
    switchUserFilter.setSwitchUserUrl("/switch");
    switchUserFilter.setExitUserUrl("/exit");
    switchUserFilter.setTargetUrl("/");

    return switchUserFilter;
  }

  //more beans

  @Override
  protected void configure(HttpSecurity http) throws Exception {
        http
                .headers().disable();
        http    //SAML CONFIG
                .httpBasic()
                .authenticationEntryPoint(samlEntryPoint()).and()
                .addFilterBefore(metadataGeneratorFilter(), ChannelProcessingFilter.class)
                .addFilterAfter(samlFilter(), BasicAuthenticationFilter.class);
        http    //DISABLE CROSS-SITE REQUEST FORGERY
                .csrf()
                .disable();
                //Impersonate Interceptor
        http
                .addFilterAfter(switchUserFilter(), FilterSecurityInterceptor.class);
        http
                .authorizeRequests()
                .antMatchers("/impersonate").permitAll()
                .antMatchers("/api/**").permitAll()
                .antMatchers("/#/**").permitAll()
                .antMatchers("/switch").permitAll()
                .antMatchers("/login").permitAll()
                .anyRequest().authenticated()
                .and()
                .formLogin().loginPage("/index")
                .permitAll().successHandler(authenticationSuccessHandler);
        http
                .logout().logoutSuccessUrl(env.getProperty("realm.url.restart"));
        http
                .exceptionHandling().accessDeniedPage("/error?code=403&error=Access Denied&detail=You are not authorized to access.");

     }    

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
    }    

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
                .authenticationProvider(samlAuthenticationProvider());
    }

    @Override
    public void configure(WebSecurity webSecutity) throws Exception {
        webSecutity
                .ignoring().antMatchers("/resources/**");
    }
}

错误:

如果您需要更多部分代码，很高兴分享。

最佳答案

您能否尝试将userDetailsS​​ervice 实现设置为配置，如this 中所示？ ？

我在你的配置中没有看到:

auth.userDetailsService(userService);

关于java - 模拟 java.lang.IllegalStateException : UserDetailsService is required，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43530277/
