RMI配置说明：
1：对象序列化：
public class Account implements Serializable{
private String name;
public String getName(){
return name;
}
public void setName(String name) {
this.name = name;
}
}
2：远程接口定义：
public interface RemoteCallExample extends Remote {
public String show() throws RemoteException;
}
3：远程接口实现：
public class RemoteCallExampleImpl implements RemoteCallExample {
@Override
public String show() throws RemoteException{
return "remote test";
}
}
4：Spring服务器端配置(使用RmiServiceExporter来)：
在WEB-INF目录下面新建remoting-servlet.xml文件，添加相关的配置。
<!- does not necessarily have to be the same name as the bean to be exported ->
<!- defaults to 1099 ->
5：服务器端类
public class RemoteCallRMI{
public String show() throws RemoteException{
return remoteCallExample.show();
}
private RemoteCallExample remoteCallExample;
public RemoteCallExample getRemoteCallExample() {
return remoteCallExample;
}
public void setRemoteCallExample(RemoteCallExample remoteCallExample) {
this.remoteCallExample = remoteCallExample;
}
}
6：服务器端配置
一些RMI问题说明：
1. RMI在启动配置中需要添加：-Djava.rmi.server.hostname=192.168.100.10
2. 需要制定相关的具体IP，把读取配置文件放到系统启动的时候处理。
Spring3.0后默认的HandlerMapping是DefaultAnnotationHandlerMapping，不是以前的BeanNameUrlHandlerMapping，所以配置Hessian和HttpInvoker的时候需要重新定义一下HandlerMapping.
在按照spring手册配置的时候需要添加定义(Spring文档有遗漏的地方)：
<!-Hessian 启动BeanNameMapping 映射功能,以httpRequest作为处理Adapter->
<!- Hessian 方式以Http进行传递 ->
测试结果
测试性能：RMI > Hessian > Http Invoker
