4. 完成功能.
(1)com.atguigu.ssh.actions包下新建EmployeeAction.java
package com.atguigu.ssh.actions; import java.util.Map; import org.apache.struts2.interceptor.RequestAware; import com.atguigu.ssh.service.EmployeeService;
import com.opensymphony.xwork2.ActionSupport; public class EmployeeAction extends ActionSupport implements RequestAware{
/**
*
*/
private static final long serialVersionUID = 1L; private EmployeeService employeeService; public void setEmployeeService(EmployeeService employeeService){
this.employeeService=employeeService;
} public String list(){
request.put("employees", employeeService.getAll());
return "list";
} //放到页面里
private Map<String,Object> request;
@Override
public void setRequest(Map<String, Object> arg0) {
this.request=arg0;
} }
com.atguigu.ssh.dao包下新建EmployeeDao.java
package com.atguigu.ssh.dao; import java.util.List; import org.hibernate.Session;
import org.hibernate.SessionFactory; import com.atguigu.ssh.entities.Employee; public class EmployeeDao { private SessionFactory sessionFactory; public void setSessionFactory(SessionFactory sessionFactory){
this.sessionFactory=sessionFactory;
} public Session getSession(){
return this.sessionFactory.getCurrentSession();
} public List<Employee> getAll(){
String hql="FROM Employee e LEFT OUTER JOIN FETCH e.department";
return getSession().createQuery(hql).list();
}
}
com.atguigu.ssh.service包下新建EmployeeService.java
package com.atguigu.ssh.service; import java.util.List; import com.atguigu.ssh.dao.EmployeeDao;
import com.atguigu.ssh.entities.Employee; public class EmployeeService { private EmployeeDao employeeDao;
public void setEmployeeDao(EmployeeDao employeeDao){
this.employeeDao=employeeDao;
} public List<Employee> getAll(){
List<Employee> employees = employeeDao.getAll();
return employees;
}
}
(2)完善applicationContext-beans.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="employeeDao" class="com.atguigu.ssh.dao.EmployeeDao">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean> <bean id="employeeService" class="com.atguigu.ssh.service.EmployeeService">
<property name="employeeDao" ref="employeeDao"></property>
</bean> <bean id="employeeAction" class="com.atguigu.ssh.actions.EmployeeAction"
scope="prototype">
<property name="employeeService" ref="employeeService"></property>
</bean>
</beans>
(3)完善struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" /> <package name="default" namespace="/" extends="struts-default">
<action name="emp-*" class="employeeAction"
method="{1}">
<result name="list">/WEB-INF/views/emp-list.jsp</result>
</action>
</package> </struts>
(4)WebContent下新建index.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<a href="emp-list">显示所有员工信息List All Employees</a>
</body>
</html>
(5)WebContent-views-emp-list.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
</head>
<body>
<h3>Employee List Page</h3> <s:if test="#request.employees == null ||#request.size()==0">
没有员工信息
</s:if>
<s:else>
<table border="1" cellpadding="10" cellspacing="0">
<tr>
<td>ID</td>
<td>LASTNAME</td>
<td>EMAIL</td>
<td>BIRTH</td>
<td>CREATETIME</td>
<td>DEPT</td>
</tr>
<s:iterator value="#request.employees">
<tr>
<td>${id}</td>
<td>${lastName}</td>
<td>${email }</td>
<td>${birth}</td>
<td>${createTime}</td>
<td>${department.departmentName}</td>
</tr>
</s:iterator>
</table>
</s:else>
</body>
</html>
(6)修改下web.xml中的信息，注册Struts2
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <!-- 配置spring配置文件.xml的名称和位置路径 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext*.xml</param-value>
</context-param> <!-- Bootstraps the root web application context before servlet initialization -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener> <!-- 配置Struts的Filter -->
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping> </web-app>
