OA项目7:系统管理之部门管理
首注：本学习教程为传智播客汤阳光讲师所公布的免费OA项目视频的文字版，本人用此来加强巩固自己开发知识，如有网友转载，请注明。谢谢。
一 根据需求，根据前台页面功能设计实体，创建javabean。Department.java，内容如下（先不处理上下级部门）：
1 package cn.clear.oa.domain; 2 3 public class Department { 4 5 private Long id; 6 private String name; 7 private String description; 8 9 public Long getId() {10 return id;11 }12 public void setId(Long id) {13 this.id = id;14 }15 public String getName() {16 return name;17 }18 public void setName(String name) {19 this.name = name;20 }21 public String getDescription() {22 return description;23 }24 public void setDescription(String description) {25 this.description = description;26 }27 28 29 }
二 根据实体创建映射文件Department.hbm.xml，内容如下：
1 <?xml version="1.0"?> 2 <!DOCTYPE hibernate-mapping PUBLIC 3 "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 4 "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 5 6 <hibernate-mapping package="cn.clear.oa.domain"> 7 <class name="Department" table="oa_department"> 8 <id name="id"><generator class="native"/></id> 9 <property name="name"/>10 <property name="description"/>11 </class>12 </hibernate-mapping>
三 在hibernate.cfg.xml中配置映射文件，内容为：
<mapping resource="cn/clear/oa/domain/Department.hbm.xml" />
四 分析功能及有几个请求：（详情见OA项目5文章中对增删改查的分析及列表，以后增删改查就采用那套模板）
五 建立DepartmentAction.java，内容如下：
1 package cn.clear.oa.view.action; 2 3 import java.util.List; 4 5 import javax.annotation.Resource; 6 7 import org.springframework.context.annotation.Scope; 8 import org.springframework.stereotype.Controller; 9 10 import cn.clear.oa.domain.Department;11 import cn.clear.oa.service.DepartmentService;12 13 import com.opensymphony.xwork2.ActionContext;14 import com.opensymphony.xwork2.ActionSupport;15 import com.opensymphony.xwork2.ModelDriven;16 17 @Controller18 @Scope("prototype")19 public class DepartmentAction extends ActionSupport implements ModelDriven<Department>{20 21 @Resource22 private DepartmentService departmentService; 23 private Department model = new Department();24 25 public Department getModel() {26 // TODO Auto-generated method stub27 return model;28 }29 30 31 public String list() throws Exception {32 33 List<Department> departmentList = departmentService.findAll();34 ActionContext.getContext().put("departmentList", departmentList);35 return "list";36 }37 public String delete() throws Exception {38 39 departmentService.delete(model.getId());40 41 return "toList";42 }43 public String add() throws Exception {44 departmentService.save(model);45 return "toList";46 }47 public String addUI() throws Exception {48 49 return "saveUI";50 }51 public String edit() throws Exception {52 53 Department department = departmentService.findById(model.getId());54 department.setName(model.getName());55 department.setDescription(model.getDescription());56 departmentService.update(department);57 return "toList";58 }59 public String editUI() throws Exception {60 61 Department department = departmentService.findById(model.getId());62 //将对象放在栈顶63 ActionContext.getContext().getValueStack().push(department);64 65 return "saveUI";66 }67 68 }
根据action添加struts.xml的action，具体如下：
1 <!-- 部门管理 -->2 <action name="department_*" class="departmentAction" method="{1}">3 <result name="list">/WEB-INF/jsp/departmentAction/list.jsp</result>4 <!-- 类型为重定向 -->5 <result name="toList" type="redirectAction">department_list</result>6 <result name="saveUI">/WEB-INF/jsp/departmentAction/saveUI.jsp</result>7 </action>
六 建立DepartmentService.java与DepartmentServiceImpl.java：
1 package cn.clear.oa.service; 2 3 import java.util.List; 4 5 import cn.clear.oa.domain.Department; 6 7 public interface DepartmentService { 8 9 List<Department> findAll();10 11 void delete(Long id);12 13 void save(Department department);14 15 Department findById(Long id);16 17 void update(Department department);18 19 }
1 package cn.clear.oa.service.impl; 2 3 import java.util.List; 4 5 import javax.annotation.Resource; 6 7 import org.springframework.stereotype.Service; 8 import org.springframework.transaction.annotation.Transactional; 9 10 import cn.clear.oa.dao.DepartmentDao;11 import cn.clear.oa.domain.Department;12 import cn.clear.oa.service.DepartmentService;13 @Service14 @Transactional15 public class DepartmentServiceImpl implements DepartmentService{16 17 @Resource18 private DepartmentDao departmentDao;19 20 public List<Department> findAll() {21 22 return departmentDao.findAll();23 }24 25 public void delete(Long id) {26 27 departmentDao.delete(id);28 29 }30 31 public void save(Department department) {32 33 departmentDao.save(department);34 }35 36 public Department findById(Long id) {37 38 return departmentDao.findById(id);39 }40 41 public void update(Department department) {42 43 departmentDao.update(department);44 }45 46 }
七 建立DepartmentDao.java与DepartmentDaoImpl.java：
1 package cn.clear.oa.dao;2 3 import cn.clear.oa.base.BaseDao;4 import cn.clear.oa.domain.Department;5 6 public interface DepartmentDao extends BaseDao<Department>{7 8 }
1 package cn.clear.oa.dao.impl; 2 3 import org.springframework.stereotype.Repository; 4 5 import cn.clear.oa.base.BaseDaoImpl; 6 import cn.clear.oa.dao.DepartmentDao; 7 import cn.clear.oa.domain.Department; 8 9 @Repository10 public class DepartmentDaoImpl extends BaseDaoImpl<Department> implements DepartmentDao {11 12 }
八 建立前台列表页面list.jsp：
1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 2 <%@ taglib prefix="s" uri="/struts-tags"%> 3 4 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 5 <html> 6 <head> 7 <title>部门列表</title> 8 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 9 <script language="javascript" src="${pageContext.request.contextPath}/script/jquery.js"></script>10 <script language="javascript" src="${pageContext.request.contextPath}/script/pageCommon.js" charset="utf-8"></script>11 <script language="javascript" src="${pageContext.request.contextPath}/script/PageUtils.js" charset="utf-8"></script>12 <link type="text/css" rel="stylesheet" href="${pageContext.request.contextPath}/style/blue/pageCommon.css" />13 <script type="text/javascript">14 </script>15 </head>16 <body>17 18 <div id="Title_bar">19 <div id="Title_bar_Head">20 <div id="Title_Head"></div>21 <div id="Title"><!--页面标题-->22 <img border="0" width="13" height="13" src="${pageContext.request.contextPath}/style/images/title_arrow.gif"/> 部门管理23 </div>24 <div id="Title_End"></div>25 </div>26 </div>27 28 <div id="MainArea">29 <table cellspacing="0" cellpadding="0" class="TableStyle">30 31 <!-- 表头-->32 <thead>33 <tr align=center valign=middle id=TableTitle>34 <td width="150px">部门名称</td>35 <td width="150px">上级部门名称</td>36 <td width="200px">职能说明</td>37 <td>相关操作</td>38 </tr>39 </thead>40 41 <!--显示数据列表-->42 <tbody id="TableData" class="dataContainer" datakey="departmentList">43 <s:iterator value="#departmentList">44 <tr class="TableDetail1 template">45 <td><a href="_list_level2.html">${name}</a> </td>46 <td>${name} </td>47 <td>${description} </td>48 <td><s:a onClick="return window.confirm(‘这将删除所有的下级部门，您确定要删除吗？‘)" action="department_delete?id=%{id}">删除</s:a>49 <s:a action="department_editUI?id=%{id}">修改</s:a>50 </td>51 </tr>52 </s:iterator>53 </tbody>54 </table>55 56 <!-- 其他功能超链接 -->57 <div id="TableTail">58 <div id="TableTail_inside">59 <s:a action="department_addUI"><img src="${pageContext.request.contextPath}/style/images/createNew.png" /></s:a>60 </div>61 </div>62 </div>63 64 <!--说明--> 65 <div id="Description"> 66 说明：<br />67 1，列表页面只显示一层的（同级的）部门数据，默认显示最顶级的部门列表。<br />68 2，点击部门名称，可以查看此部门相应的下级部门列表。<br />69 3，删除部门时，同时删除此部门的所有下级部门。70 </div>71 72 </body>73 </html>
九 建立前台保存页面saveUI.jsp：
1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 2 <%@ taglib prefix="s" uri="/struts-tags"%> 3 4 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 5 6 <html> 7 <head> 8 <title>部门设置</title> 9 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />10 <script language="javascript" src="${pageContext.request.contextPath}/script/jquery.js"></script>11 <script language="javascript" src="${pageContext.request.contextPath}/script/pageCommon.js" charset="utf-8"></script>12 <script language="javascript" src="${pageContext.request.contextPath}/script/PageUtils.js" charset="utf-8"></script>13 <link type="text/css" rel="stylesheet" href="${pageContext.request.contextPath}/style/blue/pageCommon.css" />14 </head>15 <body>16 17 <!-- 标题显示 --> 18 <div id="Title_bar">19 <div id="Title_bar_Head">20 <div id="Title_Head"></div>21 <div id="Title"><!--页面标题-->22 <img border="0" width="13" height="13" src="${pageContext.request.contextPath}/style/images/title_arrow.gif"/> 部门信息23 </div>24 <div id="Title_End"></div>25 </div>26 </div>27 28 <!--显示表单内容-->29 <div id=MainArea>30 <s:form action="department_%{id == null ? ‘add‘:‘edit‘}">31 <div class="ItemBlock_Title1"><!-- 信息说明<DIV CLASS="ItemBlock_Title1">32 <IMG BORDER="0" WIDTH="4" HEIGHT="7" SRC="http://www.mamicode.com/${pageContext.request.contextPath}/style/blue/images/item_point.gif" /> 部门信息 </DIV> -->33 </div>34 <s:hidden name="id"></s:hidden>35 <!-- 表单内容显示 -->36 <div class="ItemBlockBorder">37 <div class="ItemBlock">38 <table cellpadding="0" cellspacing="0" class="mainForm">39 <tr><td width="100">上级部门</td>40 <td><select name="parentId" class="SelectStyle">41 <option value="0" selected="selected">请选择部门</option>42 <option value="7">┠总经理室</option>43 <option value="1">┠市场部</option>44 <option value="2"> ┠咨询部</option>45 <option value="3"> ┠招生部</option>46 <option value="4">┠教学部</option>47 <option value="5">┠后勤部</option>48 </select>49 </td>50 </tr>51 <tr><td>部门名称</td>52 <td><s:textfield name="name" cssClass="InputStyle"/> *</td>53 </tr>54 <tr><td>职能说明</td>55 <td><s:textarea name="description" cssClass="TextareaStyle"></s:textarea></td>56 </tr>57 </table>58 </div>59 </div>60 61 <!-- 表单操作 -->62 <div id="InputDetailBar">63 <input type="image" src="${pageContext.request.contextPath}/style/images/save.png"/>64 <a href="javascript:history.go(-1);"><img src="${pageContext.request.contextPath}/style/images/goBack.png"/></a>65 </div>66 </s:form>67 </div>68 69 <div class="Description">70 说明：<br />71 1，上级部门的列表是有层次结构的（树形）。<br/>72 2，如果是修改：上级部门列表中不能显示当前修改的部门及其子孙部门。因为不能选择自已或自已的子部门作为上级部门。<br />73 </div>74 75 </body>76 </html>
最后启动服务器，对增删改查功能逐个测试，完成部门功能的基础功能。
