#### **SpringBoot2.x拦截器的写法：** ####

**自定义拦截器继承HandlerInterceptorAdapter**

import org.springframework.stereotype.Component;
    import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;
    
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    
    @Component
    public class AuthInterceptor extends HandlerInterceptorAdapter {
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
            // 拦截代码
            System.out.println("请求已经被拦截");
            return true;
        }
    }

**写一个类实现WebMvcConfiguration，重写addInterceptors方法**

添加自定义的拦截器（addInterceptor）；

配置需要拦截的请求（addPathPatterns）；

配置排除拦截的请求（excludePathPatterns）；

import com.sunruofei.gmall.interceptors.AuthInterceptor;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
    import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
    
    import javax.annotation.Resource;
    
    @Configuration
    public class WebMvcConfiguration implements WebMvcConfigurer {
    
        @Resource
        AuthInterceptor authInterceptor;
    
        @Override
        public void addInterceptors(InterceptorRegistry registry){
            registry.addInterceptor(authInterceptor).addPathPatterns("/**").excludePathPatterns("/error","/bootstrap/**","/css/**","/image/**","/img/**","/js/**","/scss/**");
        }
    }

### 注意：需要排除拦截的静态资源路径是static下面的目录，试过直接用/static/\*\*是不能能生效的； ###
