因为这是只学习项目，所以我没有使用数据库了，直接在Action模式几条数据了。如果使用数据库，那代码量就大了，而这个项目只是学习整合Struts2，所以不用，大家自己确定，

?

数据我是使用static来完成，只要服务器不重新启动，数据就会在，哈哈，方便呀……

?

如何大家真不想自己输入代码，就下载吧。见附件。

?

实际后台代码也是非常的简单，只有几个类User/Dept/UserAction/DeptAction

大家自己建立相应的包

?

?

代码如下：

?

1、Dept类

package com.wjt276.extjs.model;
public class Dept {

	private int id;
	
	private String name;
	
	private String description;

	public Dept(int id, String name, String description) {
		super();
		this.id = id;
		this.name = name;
		this.description = description;
	}

	public Dept() {
		super();
	}

 //……我省了getter/setter方法，在项目中大家自己生成------		
}

?2、User

?

package com.wjt276.extjs.model;

public class User {

	private int id;
	
	private String username;
	
	private String name;
	
	private String password;
	
	private boolean sex;
	
	private String phone;
	
	private String tel;
	
	private String url;
	
	private String email;
	
	private Dept dept;
	
	private String address;
	
	private String description;	

	public User() {	}
	
	public User(int id, String username, String name, String password,
			String phone, String tel, String url, String email,
			String address, boolean sex, String description) {
		super();
		this.id = id;
		this.username = username;
		this.name = name;
		this.password = password;
		this.phone = phone;
		this.tel = tel;
		this.url = url;
		this.email = email;
		this.address = address;
		this.sex = sex;
		this.description = description;
	}

   //……我省了getter/setter方法，在项目中大家自己生成------	
}

?

3、DeptAction

数据也是在这里生成的，我多加了几个对象，是为了在前台观查数据，可以不是太好，大家不要管它

package com.wjt276.extjs.action;

import java.security.SecureRandom;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import com.opensymphony.xwork2.ActionSupport;
import com.wjt276.extjs.model.Dept;

@SuppressWarnings("serial")
public class DeptAction extends ActionSupport {
	
	static SecureRandom random = new SecureRandom();  

	private Dept dept;

	private String msg;
	
	private boolean success;
	
	private int totalProperty;


	private List<Dept> depts = new ArrayList<Dept>();

	private Map<Integer, Dept> deptsMap = new HashMap<Integer, Dept>();

	private static List<Dept> lists = new ArrayList<Dept>();
	private static Map<Integer, Dept> maps = new HashMap<Integer, Dept>();

	static {
		Dept temp = new Dept(random.nextInt(100), "技术部", "技术……");
		Dept temp1 = new Dept(random.nextInt(100), "技术部5", "技术…55…");

		lists.add(temp);
		lists.add(temp1);
		maps.put(temp.getId(), temp);
		maps.put(temp1.getId(), temp1);
	}

	@Override
	public String execute() throws Exception {
		this.depts = lists;
		this.deptsMap = maps;
		this.success = true;
		this.totalProperty = this.depts.size();

		return SUCCESS;

	}

	public String add() throws Exception {
		
		System.out.println(dept.getName() + "," + dept.getDescription());
		
		Dept deptTemp = new Dept(random.nextInt(100),dept.getName(),dept.getDescription()); 
		
		lists.add(deptTemp);
		maps.put(deptTemp.getId(),deptTemp);
		
		this.success = true;
		return this.execute();
	}

	public String findDeptById(){
		this.dept = maps.get(dept.getId());
		this.success = this.dept != null;
		return SUCCESS;
	}
	
	public String delete() {
		return SUCCESS;
	}

	public String modify() throws Exception {
		if(this.dept == null){
			this.success = false;
			this.msg = "数据不合法……";
		} else {
			Dept tempDept = maps.get(dept.getId());
			this.success = tempDept != null;
			if(this.success){
				maps.put(this.dept.getId(), this.dept);
				for(int i = 0; i < lists.size(); i++){
					Dept dept3 = (Dept)lists.get(i);
					if(this.dept.getId() == dept3.
