                zuulHandlerMapping.setInterceptors(myInterceptor);

这个针对路由的url可以起拦截作用，但是我原本的Controller缺不受此拦截器控制

所以打算通过切面控制权限入手。

通过下面配置全局拦截器（SpringMVC配置模式）是起作用了的：

如下拦截器，既能拦截自定义Controller，又能拦截Zuul路由的请求（底层是ZuulController）

<mvc:interceptors>
    		<mvc:interceptor>
    			<mvc:mapping path="/**"/>
    			<mvc:exclude-mapping path="/opa/login"/>
    			<bean class="com.mortals.iot.module.common.AuthJsonInterceptor"/>
    		</mvc:interceptor>
    	</mvc:interceptors>
