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。

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;
    }

}
