Hessian+Maven Demo 一個簡單的例項(有問題，可以提問，經常線上，原始碼會粘上連線，可下載)

1:這個小Demo是我在IOS系統上搞起來的，MAVEN、JDK、TOMCAT、ECLIPSE安裝都不一一說了，可以自己嘗試一下，有問題，可以線上問我

2：這是一個Hessian入門級別的專案，專案是Maven專案、方便管理和以後整合SpringMVC。

==================================把環境搞起來，先跑一下，就知道Hessian Demo作為一個輕量級的remoting onhttp工具的大概原理了＝＝＝＝＝

1Maven的Pom.xml檔案  依賴的包（hessian的jar包，會報異常，到時候可以注意一下這個問題）

3：類，原始碼：HelloHessian.java

package com.shenhl.hession;

import java.util.List;

import java.util.Map;

public interface HelloHessian {

String sayHello();

List myLoveFruit();

Map myBabays();

MyCar getMyCar();

}

4:HelloHessianImpl介面的實現類

public void setCarModel(String carModel) {

this.carModel =carModel;

}

@Override

public String toString() {

return"my car name:[" + this.carName +"] model:[" + this.carModel +"].";

}

}
