Hessain调用expected end of map ('z') at '?'错误原因

调用的接口与实际的接口参数个数、类型不一样

hessain接口方法不能重载（方法名一样参数不一样）会报找不到方法

 

hessain方法重载解决的办法：

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

 

另外一种异情况：

Caused by: com.caucho.hessian.io.HessianProtocolException: expected integer at 0x63    
    at com.caucho.hessian.io.Hessian2Input.error(Hessian2Input.java:2705)

请检查接口编写端与调用端Hessian版本是否一致
