如何在spring-security的另一個過濾器之前添加過濾器？

Question

我的應用程序有兩種不同的安全配置。一個OAuth2SecurityConfiguration，另一個是LdapSecurityConfiguration。在OAuth2SecurityConfiguration我有以下2個filteres安全配置：

@Override 
protected void configure(HttpSecurity http) throws Exception { 
    http 
      .csrf().disable() 
      .exceptionHandling() 
      .authenticationEntryPoint(authenticationEntryPoint) 
      .and() 
       .authorizeRequests() 
       .antMatchers(OAUTH_ENDPOINT).permitAll() 
       .anyRequest().authenticated() 
      .and() 
       .logout() 
       .logoutUrl(LOGOUT_ENDPOINT) 
       .logoutSuccessUrl("/") 
       .addLogoutHandler(oAuthLogoutHandler) 
      .and() 
       .addFilterAfter(oAuth2ClientContextFilter, ExceptionTranslationFilter.class) 
       .addFilterBefore(oAuth2AuthenticationProcessingFilter, FilterSecurityInterceptor.class) 
       // anonymous login must be disabled, 
       // otherwise an anonymous authentication will be created, 
       // and the UserRedirectRequiredException will not be thrown, 
       // and the user will not be redirected to the authorization server 
       .anonymous().disable(); 
} 

LdapSecurityConfiguration安全配置：

@Override 
protected void configure(HttpSecurity http) throws Exception { 
    http 
      .csrf().disable() 
      .exceptionHandling() 
      .authenticationEntryPoint(restAuthenticationEntryPoint) 
      .and() 
       .authorizeRequests() 
       .antMatchers(AUTH_ENDPOINT).permitAll() 
       .anyRequest().authenticated() 
      .and() 
       .logout() 
      .and() 
       .addFilterBefore(authenticationFilter, OAuth2ClientContextFilter.class); 
} 

但是，當過濾器鏈被初始化我得到這個錯誤：

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.servlet.Filter]: Factory method 'springSecurityFilterChain' threw exception; nested exception is java.lang.IllegalArgumentException: Cannot register after unregistered Filter class org.springframework.security.oauth2.client.filter.OAuth2ClientContextFilter

Answer 1

How to add filter before my another filter in spring-security?

與addFilterBefore

Cannot register after unregistered Filter

，但只有當你試圖之前將其添加到一個實際上是有

問題是你有兩個不同的配置。您需要確保以正確順序應用它們（使用Ordered或@Order），或者將它們合併到單個配置中。

另請注意，您的配置嘗試配置logout()和exceptionHandling()的方式不同。你不能這樣做。

答案幫了我：https://stackoverflow.com/a/32227901/1110253。我用自定義過濾器「打包」了OAuth2AuthenticationProcessingFilter。
