Hessian一直出现' is an unknown code，开启重载了也没有解决

Question

在使用spring整合hessian的项目中，一直出现 ' is an unknown code,网上搜索结果给出的方案是方法进行启用方法重载
给出的解决方法如下：

HessianProxyFactory factory = new HessianProxyFactory();
factory.setOverloadEnabled(true);

或者spring配置文件在客户端调用的配置文件中加入如下属性：

<property name="overloadEnabled" value="true" />

以上方法均不能解决，但依旧还在报错报错内容如下：

        <property name="serviceInterface" value="com.bzqll.service.interfaces.IDdService"/>
    </bean>
</beans>

client的beans

<bean id="accountService" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
        <property name="serviceUrl" value="http://127.0.0.1:82/remoting/ddServiceHessian"/>

        <property name="overloadEnabled" value="true"/>
    </bean>

client的调用如下：

//IDdService iDdService;已经注入accountService
iDdService.test();

调用就报错，求大佬解决，如果可以的话能不能加一下QQ347784533

Answer 1

已经解决了，由于Struts2的过滤器规则中匹配所有的请求，当进行hessian请求时struts2会进行拦截，导致转发错误，只需要将过滤规则中排除hessian的请求接口

Answer 2

只需要将什么？

Answer 3

我cao，我折腾了一天，一个ssm项目做客户端，springboot项目做服务端，客户端访问一直是 '{' is an unknown code,设置了
<property name="overloadEnabled" value="true"/>
也不管用，然后我浏览器直接访问了，返回401没带token，我蒙了，一直觉得是服务端没弄好，直到你说的strus2拦截，我又想起401，跑去开放了springboot的shiro权限，然后完美运行。为了感谢你，特地注册评论。但是又要面临新的问题，因为我开放了shiro，但是没有鉴权，所以这个接口存在很大风险，但是.......管不了太多，先做出来再说。再次谢谢。
