在項目中使用了為了使用spring security的token方式進行鑒權，繼承了AbstractAuthenticationProcessingFilter來對請求攔截處理，如下：

public class JwtAuthenticationTokenFilter extends AbstractAuthenticationProcessingFilter {private SelectUserInfoWebService selectUserInfoWebService;private CacheClient cacheClient;public void setCacheClient(CacheClient cacheClient) {this.cacheClient = cacheClient;}public void setSelectUserInfoWebService(SelectUserInfoWebService selectUserInfoWebService) {this.selectUserInfoWebService = selectUserInfoWebService;}public JwtAuthenticationTokenFilter() {super("/auth/**");}@Overridepublic Authentication attemptAuthentication(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws AuthenticationException, IOException, ServletException { //部分代碼

另外需要一個集成WebSecurityConfigurerAdapter的配置類，如下，一開始是這樣寫的：

@EnableGlobalMethodSecurity(prePostEnabled = true) @Configuration public class WebSecurityConfig extends WebSecurityConfigurerAdapter {/*** 根據用戶id獲取用戶信息*/@HSFConsumer(serviceGroup = Constants.AUTHORITY_SERVICE_GROUP,serviceVersion = Constants.SERVICE_VERSION)private SelectUserInfoWebService selectUserInfoWebService;@Autowiredprivate JwtAuthenticationEntryPoint entryPoint;@Autowiredprivate CacheClient cacheClient;@Beanpublic JwtAuthenticationTokenFilter authenticationTokenFilter() throws Exception {JwtAuthenticationTokenFilter filter = new JwtAuthenticationTokenFilter();filter.setAuthenticationManager(authenticationManager());filter.setAuthenticationSuccessHandler(new AuthenticationSuccessHandlerImpl());filter.setAuthenticationFailureHandler(new AuthenticationFailureHandlerImpl());filter.setCacheClient(cacheClient);filter.setSelectUserInfoWebService(selectUserInfoWebService);return filter;}@Overrideprotected void configure(HttpSecurity http) throws Exception {http.csrf().disable().authorizeRequests().antMatchers("/auth/**").authenticated().and().exceptionHandling().authenticationEntryPoint(entryPoint).and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);http.addFilterBefore(authenticationTokenFilter(), UsernamePasswordAuthenticationFilter.class);http.headers().cacheControl();} }

問題出現了，AuthenticationSuccessHandlerImpl是
AbstractAuthenticationProcessingFilter成功后的執行方法，如下：

public class AuthenticationSuccessHandlerImpl implements AuthenticationSuccessHandler {@Overridepublic void onAuthenticationSuccess(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Authentication authentication) throws IOException, ServletException {System.out.println("Successfully Authentication");} }

發現，每次都執行了兩次

后來發現是@Bean注解導致的，繼承了AbstractAuthenticationProcessingFilter的JwtAuthenticationTokenFilter本來就會被加載，加了bean注解，會被加載兩次，刪除后就好了。。。。

總結

以上是生活随笔為你收集整理的记一次继承了AbstractAuthenticationProcessingFilter 的过滤器被执行了两次问题的全部內容，希望文章能夠幫你解決所遇到的問題。
