1.問題:

要添加一个自定义处理Token的问题,现在实现了方法,却发现拦截器没有被调用。 我是在自定义的HandlerInterceptorAdapter里面重写了preHandle方法。并把这个自定义的HandlerInterceptorAdapter添加到了自定义的WebMvcConfigurerAdapter,在WebMvcConfigurerAdapter添加@Configuration注解,但是却没有被调用!

2.程式碼:
自訂的HandlerInterceptorAdapter的AccessTokenVerifyInterceptor:

@Component public class AccessTokenVerifyInterceptor extends HandlerInterceptorAdapter { private Logger logger = LoggerFactory.getLogger(AccessTokenVerifyInterceptor.class); @Autowired private FFAccessTokenService tokenService; @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { // TODO Auto-generated method stub logger.info("AccessToken executing ..."); return true; } }

自訂的WebMvcConfigurerAdapter類別FFWebMvcConfigurer:

@Configuration public class FFWebMvcConfigurer extends WebMvcConfigurerAdapter { @Override public void addViewControllers(ViewControllerRegistry registry) { // TODO Auto-generated method stub registry.addViewController("/error").setViewName("404.html"); registry.setOrder(Ordered.HIGHEST_PRECEDENCE); super.addViewControllers(registry); } @Override public void configurePathMatch(PathMatchConfigurer configurer) { configurer.setUseSuffixPatternMatch(false); super.configurePathMatch(configurer); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new AccessTokenVerifyInterceptor()) .addPathPatterns("/**") .excludePathPatterns("/access-token"); super.addInterceptors(registry); System.out.println("开始开始咯。。。。"); } }

3.希望各路大神,幫小弟指點指點,感謝感謝!

/**去掉一個*試試

    扔个三星炸死你

    在啟動類別中加上
    @ServletComponentScan

      阿神

      那你應該把 HandlerInterceptorAdapter 貼出來看看
      還有就是 2 中那個 @Component 註解 是沒有意義的。

        学霸

        不會啊,按照你的程式碼寫了一個簡單的Demo,攔截器是可以呼叫的。

        @Configuration public class FFWebMvcConfigurer extends WebMvcConfigurerAdapter { @Override public void addViewControllers(ViewControllerRegistry registry) { registry.addViewController("/error").setViewName("404.html"); registry.setOrder(Ordered.HIGHEST_PRECEDENCE); super.addViewControllers(registry); } @Override public void configurePathMatch(PathMatchConfigurer configurer) { configurer.setUseSuffixPatternMatch(false); super.configurePathMatch(configurer); } @Override public void addInterceptors(InterceptorRegistry registry) { registry.addInterceptor(new AccessTokenVerifyInterceptor()) .addPathPatterns("/**") .excludePathPatterns("/access-token"); super.addInterceptors(registry); System.out.println("开始开始咯。。。。"); } }
        public class AccessTokenVerifyInterceptor extends HandlerInterceptorAdapter { @Override public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception { System.out.println("preHandle..."); return true; } }
