1. Frage:

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. Code:
AccessTokenVerifyInterceptor des benutzerdefinierten HandlerInterceptorAdapter:

@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;    
    }
    
}

Angepasste WebMvcConfigurerAdapter-Klasse 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. Ich hoffe, dass mir alle Meister einen Rat geben können, danke!

/**去掉一个*试试

扔个三星炸死你

在启动类加上
@ServletComponentScan

阿神

那你应该把 HandlerInterceptorAdapter 贴出来看看
还有就是 2 中那个 @Component 注解 是没有意义的。

学霸

不会啊,按照你的代码写了一个简单的Demo,拦截器是可以调用到的。

@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;
    }

}
