拦截器

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {



    @Override
    public void addInterceptors(InterceptorRegistry registry) {

        //  /**表示拦截所有请求
        String[] addPath = {"/**"};
        // 放行getStudent和getUser两个请求：其中getUser请求没有对应的处理器
        String[] excludePath = {"/getStudent","/getUser"};
        registry.addInterceptor(new InterceptorByInterface()).addPathPatterns(addPath).excludePathPatterns(excludePath);
    }

}

//通过实现HandlerInterceptor接口实现拦截,这个类需要注册
public class InterceptorByInterface implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {




        return true;
    }
}
