客户端配置信息
<!-- hessian连接服务器接口地址 -->
     <bean id="apiService" class="org.springframework.remoting.caucho.HessianProxyFactoryBean">
        <property name="serviceUrl" value="http://192.168.1.57:8082/cms-web/cpsService" />
        <property name="serviceInterface" value="com.hessian.service.CpsService" />
      <!--  新增overloadEnabled属性,并把它的值设置为true,默认是false,则Hessian就能支持方法的重载了。   -->
        <property name="overloadEnabled" value="true" />
    </bean>

这是因为接口中出现方法重载,在调用时,服务器端会跑出异常。
在整合spring中,在客户端的配置里面加上如下代码可以解决:
Java代码 收藏代码

spring2.5.6 + hessian 4.0.1,采用remoting-servlet.xml的方式进行配置,客户端调用时出现如下错误,换成hessian 3.1.5就正常了。
