一... 设计实体类/表
1. 写实体类Department.java:
package cn.itcast.oa.domain; public class Department { private Long id; private String name; private String description; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } }
2. 写映射文件Department.hbm.xml
<?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="cn.itcast.oa.domain"> <class name="Department" table="itcast_department"> <id name="id"> <generator class="native"></generator> </id> <property name="name" /> <property name="description" /> </class> </hibernate-mapping>
3. 把实体类加入到hibernate.cfg.xml
<?xml version=‘1.0‘ encoding=‘utf-8‘?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="dialect">org.hibernate.dialect.MySQLDialect</property> <!-- 2. other configuration --> <property name="show_sql">true</property> <property name="hbm2ddl.auto">update</property> <property name="connection.pool_size">1</property> <!--3. mapping --> <mapping resource="cn/itcast/oa/domain/User.hbm.xml" /> <mapping resource="cn/itcast/oa/domain/Role.hbm.xml" /> <mapping resource="cn/itcast/oa/domain/Department.hbm.xml" /> </session-factory> </hibernate-configuration>
4. 测试类生成表:SpringTest.java
package cn.itcast.oa.test; import org.hibernate.SessionFactory; import org.junit.Test; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class SpringTest { private ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml"); @Test public void testSessionFactory() throws Exception{ SessionFactory sessionFactory = (SessionFactory)ac.getBean("sessionFactory"); System.out.println(sessionFactory); } }
确认生成表成功!!!
二.. 分析有几个功能, 对应几个请求
1. 搭action框架
注意: @Controller @Scope("prototype")
package cn.itcast.oa.view.action; import javax.annotation.Resource; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Controller; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; @Controller @Scope("prototype") public class DepartmentAction extends ActionSupport{ /*列表*/ public String list() throws Exception { return "list"; } /*删除*/ public String delete() throws Exception { return "toList"; } /*添加页面*/ public String addUI() throws Exception { return "saveUI"; } /*添加*/ public String add() throws Exception { return "toList"; } /*修改页面*/ public String editUI() throws Exception { return "saveUI"; } /*修改*/ public String edit() throws Exception { return "toList"; } }
2. 配置struts.xml:
<!-- 部门管理 --> <action name="department_*" class="departmentAction" method="{1}"> <result name="list">/WEB-INF/jsp/departmentAction/list.jsp</result> <result name="saveUI">/WEB-INF/jsp/departmentAction/saveUI.jsp</result> <result name="toList" type="redirectAction">department_list</result> </action>
3. 写两个简单的jsp文件, 验证成功
4. 开始完善action:
package cn.itcast.oa.view.action; import java.util.List; import javax.annotation.Resource; import org.springframework.context.annotation.Scope; import org.springframework.stereotype.Controller; import cn.itcast.oa.domain.Department; import cn.itcast.oa.service.DepartmentService; import com.opensymphony.xwork2.ActionContext; import com.opensymphony.xwork2.ActionSupport; import com.opensymphony.xwork2.ModelDriven; @Controller @Scope("prototype") public class DepartmentAction extends ActionSupport implements ModelDriven<Department>{ @Resource private DepartmentService departmentService; private Department model = new Department(); /*列表*/ public String list() throws Exception { List<Department> departmentList = departmentService.findAll(); ActionContext.getContext().put("departmentList", departmentList); return "list"; } /*删除*/ public String delete() throws Exception { departmentService.delete(model.getId()); return "toList"; } /*添加页面*/ public String addUI() throws Exception { return "saveUI"; } /*添加*/ public String add() throws Exception { departmentService.save(model); return "toList"; } /*修改页面*/ public String editUI() throws Exception { /*准备回显数据*/ Department department = departmentService.getById(model.getId()); ActionContext.getContext().getValueStack().push(department); return "saveUI"; } /*修改*/ public String edit() throws Exception { // 1. 从数据库取出原对象 Department department = departmentService.getById(model.getId()); //2. 设置要修改的属性 department.setName(model.getName()); department.setDescription(model.getDescription()); //3. 更新到数据库 departmentService.update(department); return "toList"; } public Department getModel() { // TODO Auto-generated method stub return model; } }
5. 写service接口, DepartmentService.java, 是在action里调用方法的时候ctrl+1创建的方法
package cn.itcast.oa.service; import java.util.List; import cn.itcast.oa.domain.Department; public interface DepartmentService { List<Department> findAll(); void delete(Long id); void save(Department model); Department getById(Long id); void update(Department department); }
6. 创建DepartmentService接口的实现类, DepartmentServiceImpl.java
注意@Service, @Transactional, 用Dao的时候用@Resource
package cn.itcast.oa.service.impl; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import cn.itcast.oa.dao.DepartmentDao; import cn.itcast.oa.domain.Department; import cn.itcast.oa.service.DepartmentService; @Service @Transactional public class DepartmentServiceImpl implements DepartmentService{ @Resource private DepartmentDao departmentDao; public List<Department> findAll() { return departmentDao.findAll(); } public void delete(Long id) { departmentDao.delete(id); } public void save(Department model) { departmentDao.save(model); } public Department getById(Long id) { return departmentDao.getById(id); } public void update(Department department) { departmentDao.update(department); } }
三.. 创建Dao接口和实现类
1. Dao接口, DepartmentDao.java, 注意要继承BaseDao接口
package cn.itcast.oa.dao; import cn.itcast.oa.base.BaseDao; import cn.itcast.oa.domain.Department; public interface DepartmentDao extends BaseDao<Department>{ }
2. 实现类DepartmentDaoImpl.java,
注意1. 继承BaseDaoImpl, 2. 实现DepartmentDao 3. @Repository
package cn.itcast.oa.dao.impl; import org.springframework.stereotype.Repository; import cn.itcast.oa.base.BaseDaoImpl; import cn.itcast.oa.dao.DepartmentDao; import cn.itcast.oa.domain.Department; @Repository public class DepartmentDaoImpl extends BaseDaoImpl<Department> implements DepartmentDao{ }
四.. 写jsp页面:
新建jsp路径下的departmentAction文件夹, 创建两个jsp文件夹, list.jsp,和 saveUI.jsp
list.jsp:
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <%String path = request.getContextPath();%> <html> <head> <title>部门列表</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script language="javascript" type="text/javascript" src=<%=path%>/script/jquery.js"></script> <script language="javascript" type="text/javascript" src=<%=path%>/script/pageCommon.js"></script> <script language="javascript" type="text/javascript" src=<%=path%>/script/PageUtils.js"></script> <link type="text/css" rel="stylesheet" href="<%=path%>/style/blue/pageCommon.css"/> <script type="text/javascript"> </script> </head> <body> <div id="Title_bar"> <div id="Title_bar_Head"> <div id="Title_Head"></div> <div id="Title"><!--页面标题--> <img border="0" width="13" height="13" src="<%=path%>/style/images/title_arrow.gif"/> 部门管理 </div> <div id="Title_End"></div> </div> </div> <div id="MainArea"> <table cellspacing="0" cellpadding="0" class="TableStyle"> <!-- 表头--> <thead> <tr align=center valign=middle id=TableTitle> <td width="150px">部门名称</td> <td width="150px">上级部门名称</td> <td width="200px">职能说明</td> <td>相关操作</td> </tr> </thead> <!--显示数据列表--> <tbody id="TableData" class="dataContainer" datakey="departmentList"> <s:iterator value="#departmentList"> <tr class="TableDetail1 template"> <td>${name} </td> <td>${parent.name} </td> <td>${description} </td> <td> <s:a action="department_delete?id=%{id}" onclick="return window.confirm(‘这将删除所有的下级部门,您确定要删除吗?‘)">删除</s:a> <s:a action="department_editUI?id=%{id}">修改</s:a> </td> </tr> </s:iterator> </tbody> </table> <!-- 其他功能超链接 --> <div id="TableTail"> <div id="TableTail_inside"> <s:a action="department_addUI"><img src="<%=path%>/style/images/createNew.png" /></s:a> </div> </div> </div> <!--说明--> <div id="Description"> 说明:<br /> 1,列表页面只显示一层的(同级的)部门数据,默认显示最顶级的部门列表。<br /> 2,点击部门名称,可以查看此部门相应的下级部门列表。<br /> 3,删除部门时,同时删除此部门的所有下级部门。 </div> </body> </html>
saveUI.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <%String path = request.getContextPath();%> <html> <head> <title>部门设置</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script language="javascript" type="text/javascript" src=<%=path%>/script/jquery.js"></script> <script language="javascript" type="text/javascript" src=<%=path%>/script/pageCommon.js"></script> <script language="javascript" type="text/javascript" src=<%=path%>/script/PageUtils.js"></script> <link type="text/css" rel="stylesheet" href="<%=path%>/style/blue/pageCommon.css"/> </head> <body> <!-- 标题显示 --> <div id="Title_bar"> <div id="Title_bar_Head"> <div id="Title_Head"></div> <div id="Title"><!--页面标题--> <img border="0" width="13" height="13" src="<%=path%>/style/images/title_arrow.gif"/> 部门信息 </div> <div id="Title_End"></div> </div> </div> <!--显示表单内容--> <div id=MainArea> <s:form action="department_%{id == null ? ‘add‘ : ‘edit‘}"> <s:hidden name="id"></s:hidden> <div class="ItemBlock_Title1"><!-- 信息说明<DIV CLASS="ItemBlock_Title1"> <IMG BORDER="0" WIDTH="4" HEIGHT="7" SRC="${pageContext.request.contextPath}/style/blue/images/item_point.gif" /> 部门信息 </DIV> --> </div> <!-- 表单内容显示 --> <div class="ItemBlockBorder"> <div class="ItemBlock"> <table cellpadding="0" cellspacing="0" class="mainForm"> <tr><td width="100">上级部门</td> <td><select name="parentId" class="SelectStyle"> <option value="">请选择部门</option> <option value="7">┠总经理室</option> <option value="1">┠市场部</option> <option value="2"> ┠咨询部</option> <option value="3"> ┠招生部</option> <option value="4">┠教学部</option> <option value="5">┠后勤部</option> </select> </td> </tr> <tr><td>部门名称</td> <td><s:textfield name="name" cssClass="InputStyle"/> *</td> </tr> <tr><td>职能说明</td> <td><s:textarea name="description" cssClass="TextareaStyle"></s:textarea></td> </tr> </table> </div> </div> <!-- 表单操作 --> <div id="InputDetailBar"> <input type="image" src="<%=path%>/style/images/save.png"/> <a href="javascript:history.go(-1);"><img src="<%=path%>/style/images/goBack.png"/></a> </div> </s:form> </div> <div class="Description"> 说明:<br /> 1,上级部门的列表是有层次结构的(树形)。<br/> 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 /> </div> </body> </html>
