ssh+json标准的结构Demo

ssh整合+json实现增删改查，一个标准的Demo，可以按这个模式开发，感觉蛮方便的，记录下来，避免忘记。

数据库：Oracle；平台：myeclipse

项目结构：

POJO类和映射文件：

package org.jvsun.pojo;

/**

public class UserInfo implements java.io.Serializable {

	// Fields

	private Integer userId;

	private String userTel;

	// Constructors

	public UserInfo() {
	}

	/** full constructor */
	public UserInfo(String userName, String userPassword, String userRemark,

		this.userName = userName;
		this.userPassword = userPassword;
		this.userRemark = userRemark;
		this.userEmail = userEmail;
		this.userTel = userTel;
	}

	// Property accessors

大部分人有了ssh所需的包，这里是Json包的下载地址：http://download.csdn.net/detail/weixin_36380516/9851590

改进一下，部分html页面在action中写让代码看起来有点乱，现在把他扔回jsp里，可以这样写：

action中

public String findAll() {  
        int count = this.services.findCountById(buyId);  
        List<Buy> list = this.services.findById(buyId, currentPage, pageSize);
        jsonA = new JSONArray();
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("count", count);
        jsonA.add(jsonObject);
        for (int i = 0; i < list.size(); i++) {
			Buy pojo = list.get(i);
			JSONObject jsonO = new JSONObject();
			jsonO.put("buyId", pojo.getBuyId());
			jsonO.put("userid",pojo.getUserId());
			jsonO.put("buyDate",DataConverter.dataToString(DataConverter.toShortDate(pojo.getBuyDate()), "yyyy-MM-dd"));
			jsonA.add(jsonO);
		}
        
        return "succ";  
    }  

$(document).ready(function (){
		$.post("<%=path%>/buy_findAll",{buyId:bid,currentPage:pagecur,pageSize:pagesize},
			function(data){//Servlet执行完之后执行方法，data表示的servlet返回数据内容
	 				var object = eval(data);//将字符串转换成json类型
	 				var showT = "<table>  <tr> <th>采购单编号</th> <th>采购员</th> <th>采购时间</th> <th>操作</th> </tr>";
	 				for(var i = 1;i<object.length;i++){
	 					var item = object[i];
	 					showT = showT+"<tr><td>"+item.buyId+"</td><td >"+item.userid+"</td><td>"+item.buyDate+"</td><td><a href='#' onclick='goUpd(" + item.buyId + ")'>更新</a><a href='#' onclick='goDel("
					+ item.buyId + ")'>删除</a></td></tr>";
	 				}
	 				showT = showT + "</table>";
	 				$("#showTable").html(showT);
	 				count=object[0].count;
	 				calc();//计算总页数，控制按钮是否可用
	 			});
			
		});
