1，要求

四种框架中的一种来实现企业工单管理系统，Oracle 10g/11g 或 MySQL 5 作为后台数据

库。该系统包括查看所有的项目信息、选择项目后进行工单添加、添加完毕后显示添加后的工单

信息三大功能，具体要求如下：

打开企业工单管理系统首页，下拉框列出所有项目，如图-1 所示。

选择需要添加工单的项目，点击“确定”按钮，进入工单录入界面，级别下拉列表正确显示 1

级，2 级，3 级。如图-2 所示：

添加工单界面，需要输入执行人和任务描述，在点击“提交”时，需要执行非空验证，如果

执行人为空，提示“执行人不能为空！”，如果任务描述为空，则提示“任务描述不能为空！”，

页面效果如图-3 所示。

输入执行人和任务描述后点击“提交”， 注意 ： 此工单需要添加到所选择的项目中 。 请在保

存记录的同时 ， 自动保存记录的生成时间 。保存成功或者失败都跳转到工单信息列表，列表

下方显示“保存成功”或“保存失败”提示语句，列表按照工单编号降序排列，级别需要根据数

据库值做对应显示(1-1 级，2-2 级，3-3 级),创建时间按年-月-日显示，列表采用隔行变色样

式。如图-4 所示。

2，我的数据库

3，使用 idea 工具和 mybatis 框架实现以上功能

(1)我的项目最终形成的样式：

(2)下面详细介绍我的项目

entity实体类

Project

package cn.happy.entity;

public class Project {

private int id;//工单编号

private String projectName;//项目名字

public Project() {

}

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getProjectName() {

return projectName;

}

public void setProjectName(String projectName) {

this.projectName = projectName;

}

}

workorder

package cn.happy.entity;

import java.util.Date;

public class Workorder {

private int id;//工单编号

private int projectId;//项目编号

private String executor;//执行人名单

private String discription;//任务描述

private int orderLevel;//工单等级

private Date createDate;//添加时间

private Project project;

public Workorder(int id, int projectId, String executor, String discription, int orderLevel, Date createDate, Project project) {

this.id = id;

this.projectId = projectId;

this.executor = executor;

this.discription = discription;

this.orderLevel = orderLevel;

this.createDate = createDate;

this.project = project;

}

public int getProjectId() {

return projectId;

}

public void setProjectId(int projectId) {

this.projectId = projectId;

}

public Workorder() {

}

public Project getProject() {

return project;

}

public void setProject(Project project) {

this.project = project;

}

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getExecutor() {

return executor;

}

public void setExecutor(String executor) {

this.executor = executor;

}

public String getDiscription() {

return discription;

}

public void setDiscription(String discription) {

this.discription = discription;

}

public int getOrderLevel() {

return orderLevel;

}

public void setOrderLevel(int orderLevel) {

this.orderLevel = orderLevel;

}

public Date getCreateDate() {

return createDate;

}

public void setCreateDate(Date createDate) {

this.createDate = createDate;

}

}

我的 util 层

package cn.happy.util;

import org.apache.ibatis.io.Resources;

import org.apache.ibatis.session.SqlSession;

import org.apache.ibatis.session.SqlSessionFactory;

import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import java.io.InputStream;

/**

* SqlSessionFactory的单列类

* 工具类的目的就是创建sqlSession对象

*/

public class sessionFactory {

//01.创建需要单例的对象实例

private static SqlSessionFactory sessionFactory;

//02.私有化构造

public sessionFactory() {

}

/**

* 对外提供访问的接口

* 001.SqlSession的创建依赖SqlSessionFactory

* 002.SqlSessionFactory依赖于SqlSessionFactoryBuilder

* 003.SqlSessionFactoryBuilder依赖于配置文件

* 004.获取配置文件

*/

public static synchronized SqlSession getSqlSession(){

try {

InputStream stream= Resources.getResourceAsStream("mybatis-config.xml");

//判断sqlSessionFactory是否为空

if(sessionFactory==null){

sessionFactory=new SqlSessionFactoryBuilder().build(stream);

}

} catch (Exception e) {

e.printStackTrace();

} /**

* 之前还需要写一个finally用来关闭流！ 现在不需要 为什么不需要??

* 01.查询源码build(stream)

* 02.SqlSessionFactoryBuilder类中已经关闭reader.close()

* 03.所以我们如果关闭流 会报错！

*/

return sessionFactory.openSession(true);//创建session返回

}

}

我的dao层

IProjectDAO

package cn.happy.dao;

import cn.happy.entity.Project;

import java.util.List;

public interface IProjectDAO {

//01查询所有项目

public List findAll();

}

IProjectDAO。xml 文件

/p>

PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

SELECT * from project

IWorkorderDAO接口

package cn.happy.dao;

import cn.happy.entity.Workorder;

import java.util.List;

public interface IWorkorderDAO {

//添加工单

public int addWork(Workorder work);

//查询所有工单

public List findAllWork();

}

IWorkorderDAO.xml 文件

/p>

PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

"http://mybatis.org/dtd/mybatis-3-mapper.dtd">

INSERT into workorder(projectId,executor,discription,orderLevel,createDate) VALUES (#{projectId},#{executor},#{discription},#{orderLevel},#{createDate})

SELECT id,projectId,executor,discription,orderLevel,createDate from workorder ORDER BY id DESC

select * from project where id=#{projectId}

我的service层

IProjectService接口

package cn.happy.service;

import cn.happy.entity.Project;

import java.util.List;

public interface IProjectService {

//01查询所有项目

public List findAll();

}

ProjectServiceImpl 实现类文件

package cn.happy.service.impl;

import cn.happy.dao.IProjectDAO;

import cn.happy.entity.Project;

import cn.happy.service.IProjectService;

import cn.happy.util.sessionFactory;

import org.apache.ibatis.session.SqlSession;

import java.util.List;

public class ProjectServiceImpl implements IProjectService{

IProjectDAO dao;

SqlSession session;

public ProjectServiceImpl() {

session= sessionFactory.getSqlSession();

dao=session.getMapper(IProjectDAO.class);

}

public List findAll() {

return dao.findAll();

}

}

IWorkorderService接口

package cn.happy.service;

import cn.happy.entity.Workorder;

import java.util.List;

public interface IWorkorderService {

//添加工单

public int addWork(Workorder work);

//查询所有工单

public List findAllWork();

}

WorkorderServiceImpl实现类文件

package cn.happy.service.impl;

import cn.happy.dao.IWorkorderDAO;

import cn.happy.entity.Workorder;

import cn.happy.service.IWorkorderService;

import cn.happy.util.sessionFactory;

import org.apache.ibatis.session.SqlSession;

import java.util.List;

public class WorkorderServiceImpl implements IWorkorderService{

IWorkorderDAO dao;

SqlSession session;

public WorkorderServiceImpl() {

session= sessionFactory.getSqlSession();

dao=session.getMapper(IWorkorderDAO.class);

}

public int addWork(Workorder work) {

return dao.addWork(work);

}

public List findAllWork() {

return dao.findAllWork();

}

}

我的servilet层

先看看ProjectServlet层

package cn.happy.servlet;

import cn.happy.entity.Project;

import cn.happy.service.IProjectService;

import cn.happy.service.impl.ProjectServiceImpl;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.util.List;

@WebServlet("/showAll")

public class ProjectServlet extends HttpServlet {

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

doGet(request,response);

}

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

request.setCharacterEncoding("utf-8");

IProjectService service=new ProjectServiceImpl();

List all= service.findAll();

request.setAttribute("all",all);

System.out.println("==============="+all);

request.getRequestDispatcher("index.jsp").forward(request,response);

}

}

addProjectServlet

package cn.happy.servlet;

import org.apache.log4j.helpers.FileWatchdog;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

@WebServlet("/addProjectServlet")

public class addProjectServlet extends HttpServlet {

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

doGet(request,response);

}

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

request.setCharacterEncoding("utf-8");

String projectId = request.getParameter("projectId");

request.setAttribute("projectId",projectId);

request.getRequestDispatcher("add.jsp").forward(request,response);

System.out.println("=========addproject=========");

}

}

在看看addWorkorderServilet

package cn.happy.servlet;

import cn.happy.entity.Workorder;

import cn.happy.service.IWorkorderService;

import cn.happy.service.impl.WorkorderServiceImpl;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.util.Date;

@WebServlet( "/addWorkorderServlet")

public class addWorkorderServlet extends HttpServlet {

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

doGet(request,response);

}

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

System.out.println("========开始添加工单===========");

request.setCharacterEncoding("utf-8");

String id = request.getParameter("id");

String executor = request.getParameter("name");

String description = request.getParameter("description");

String orderLevel = request.getParameter("orderLevel");

System.out.println("========获取添加内容===========");

Workorder work=new Workorder();

work.setCreateDate(new Date());//日期

work.setProjectId(Integer.parseInt(id));

work.setExecutor(executor);

work.setDiscription(description);

work.setOrderLevel(Integer.parseInt(orderLevel));

IWorkorderService service=new WorkorderServiceImpl();

System.out.println("========加入方法中===========");

int num=service.addWork(work);

System.out.println("----------"+num);

if (num>0){

System.out.println("======if>0=======");

String add="添加成功！";

request.setAttribute("add",add);

}else {

System.out.println("======if<0=======");

String add="添加失败！";

request.setAttribute("add",add);

}

System.out.println("======结束=======");

request.getRequestDispatcher("/findWorkorderServlet").forward(request,response);

}

}

最后findWorkorderServlet

package cn.happy.servlet;

import cn.happy.entity.Workorder;

import cn.happy.service.IWorkorderService;

import cn.happy.service.impl.WorkorderServiceImpl;

import javax.servlet.ServletException;

import javax.servlet.annotation.WebServlet;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import java.io.IOException;

import java.util.List;

@WebServlet("/findWorkorderServlet")

public class findWorkorderServlet extends HttpServlet {

public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

doGet(request,response);

}

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

request.setCharacterEncoding("utf-8");

IWorkorderService service=new WorkorderServiceImpl();

List allWork = service.findAllWork();

request.setAttribute("allWork",allWork);

request.getRequestDispatcher("show.jsp").forward(request,response);

}
