項目結構:

所需jar包:或使用mysql，只需在c3p0連接池更改爲mysql數據庫即可

一、數據表設計:

--------------------------------------------------------

-- 文件已創建 - 星期三-十一月-13-2013

-- DDL for Table ACCOUNT

--------------------------------------------------------

CREATETABLE"SCOTT"."ACCOUNT"

( "PID" VARCHAR2(20 BYTE),

"PNAME" VARCHAR2(20 BYTE),

"PDEPT" VARCHAR2(20 BYTE)

Insert into SCOTT.ACCOUNT (PID,PNAME,PDEPT)values ('735a','王六','技術部');

Insert into SCOTT.ACCOUNT (PID,PNAME,PDEPT)values ('41d8','小三','積澱');

二、C:Action

package com.test.action;

import java.sql.SQLException;

import java.util.List;

import javax.servlet.ServletContext;

import org.apache.struts2.ServletActionContext;

import javassist.expr.NewArray;

import com.opensymphony.xwork2.ActionSupport;

import com.test.dao.Account;

import com.test.dao.AccountDao;

public class AccountAction extends ActionSupport{

/**

private static final long serialVersionUID = -2380007467627219743L;

private static AccountDao accountDao=new AccountDao() ;

private Account account;

private String id;

private List<Account> all;

public String getId() {

return id;

}

public void setId(String id) {

this.id = id;

}

public List<Account> getAll() {

return all;

}

public void setAll(List<Account> all) {

this.all = all;

}

public Account getAccount() {

return account;

}

public void setAccount(Account account) {

this.account = account;

}

public String queryAll(){

all=accountDao.accountList();

return "list";

}

public String queryById(){

try {

account=accountDao.findAccountById(id);

} catch (SQLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return "update";

}

public String save(){

accountDao.insert(account);

return queryAll();

}

public String delete(){

accountDao.deleteAccount(id);

return queryAll();

}

public String update(){

String pid=ServletActionContext.getRequest().getParameter("pid");

System.out.println("account pid="+pid);

account.setPid(pid);

accountDao.update(account);

return queryAll();

}
