MyBatis 3章 MyBatis Spring Struts2 整合应用

1、技术目标

为项目添加Struts2框架
整合Spring与strtus2
为项目添加jsp页面，操作影片CRUD

注意：关于strtus2框架其他方面的应用细节不在本文讨论范围

2、使用准备

2.1） 在项目(Web)中新增如下jar包，struts版本2.2.1.1(本文已提供下载)：

commons-fileupload-1.2.1.jar

commons-io-1.3.2.jar

commons-logging-1.1.1.jar

freemarker-2.3.16.jar

javassist-3.12.0.GA.jar

ognl-3.0.jar

struts2-core-2.2.1.1.jar

struts2-spring-plugin-2.2.1.1.jar

xwork-core-2.2.1.1.jar

2.2）创建如下包，放置struts控制器(Action)代码：

com.xxx.web.struts.action

2.3）在src下创建Spring配置文件applicationContext-actions.xml ，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
	<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<!-- 这里配置Action -->
	
</beans>

2.4）在src下创建struts2配置文件struts.xml ，内容如下：

<?xml version="1.0" encoding="UTF-8" ?>
	<!DOCTYPE struts PUBLIC
	    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
	    "http://struts.apache.org/dtds/struts-2.0.dtd">
	
	<struts>
		<constant name="struts.enable.DynamicMethodInvocation" value="true" />
		<constant name="struts.devMode" value="true" />
		<constant name="struts.i18n.encoding" value="UTF-8" />
		<constant name="struts.objectFactory" value="spring" />
		<constant name="struts.objectFactory.spring.autoWire" value="type" />
		<constant name="struts.ui.theme" value="simple"></constant>
		<package name="film" namespace="/film" extends="struts-default">
			<!-- 设置Action -->
		</package>
</struts>

2.5）web.xml 中配置struts2

<?xml version="1.0" encoding="UTF-8"?>
	<web-app version="2.5" 
		xmlns="http://java.sun.com/xml/ns/javaee" 
		xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
		xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
		http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	  <welcome-file-list>
	    <welcome-file>index.jsp</welcome-file>
	  </welcome-file-list>
	  
	  	<context-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>
		</context-param>
		
		<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>
		
		<listener>
			<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
		</listener>
	  
	</web-app>

3、在com.xxx.web.struts.action包下创建类FilmAction，如下：

package com.xxx.web.struts.action;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
import com.xxx.pojo.Film;
import com.xxx.service.FilmService;

@SuppressWarnings("serial")
public class FilmAction extends ActionSupport implements ModelDriven<Film> {

	//业务逻辑对象
	@Autowired
	private FilmService filmService;
	
	//封装查询结果
	private List<Film> filmList;
	
	//封装页面提交的表单数据
	private Film film = new Film();
	
	/**
	 * 获取所有的电影
	 * @return
	 * @throws Exception
	 */
	public String findFilm() throws Exception {
		
		this.filmList = this.filmService.getAllFilm();
		return SUCCESS;
	}
	
	/**
	 * 根据影片ID获取影片信息
	 * @return
	 * @throws Exception
	 */
	public String detailFilm() throws Exception {

		int id = film.getId().intValue();
		Film film = this.filmService.getFilmById(id);
		this.film.setFname(film.getFname());
		return SUCCESS;
	}
	
	/**
	 * 添加影片
	 * @return
	 * @throws Exception
	 */
	public String insertFilm() throws Exception {

		this.filmService.insertFilm(film);
		return SUCCESS;
	}
	
	/**
	 * 修改影片
	 * @return
	 * @throws Exception
	 */
	public String updateFilm() throws Exception {

		this.filmService.updateFilm(film);
		return SUCCESS;
	}
	
	/**
	 * 删除影片
	 * @return
	 * @throws Exception
	 */
	public String deleteFilm() throws Exception {

		int id = film.getId().intValue();
		this.filmService.deleteFilm(id);
		return SUCCESS;
	}
	
	public Film getModel() {
		return film;
	}

	public List<Film> getFilmList() {
		return filmList;
	}

	public void setFilmList(List<Film> filmList) {
		this.filmList = filmList;
	}

}

4、在applicationContext-actions.xml中配置FilmAction

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<!-- 创建FilmAction -->
	<bean id="filmAction"	
		class="com.xxx.web.struts.action.FilmAction"
		scope="prototype"/>
	
</beans>

5、在struts.xml中配置Action

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	<constant name="struts.enable.DynamicMethodInvocation" value="true" />
	<constant name="struts.devMode" value="true" />
	<constant name="struts.i18n.encoding" value="UTF-8" />
	<constant name="struts.objectFactory" value="spring" />
	<constant name="struts.objectFactory.spring.autoWire" value="type" />
	<constant name="struts.ui.theme" value="simple"></constant>
	
	<package name="film" namespace="/film" extends="struts-default">
		
		<!-- 获取所有影片 -->
		<action name="findFilm" class="filmAction" method="findFilm">
			<result name="success">/manager/films.jsp</result>
		</action>
		<!-- 添加影片 -->
		<action name="insertFilm" class="filmAction" method="insertFilm">
			<result name="success" type="redirectAction">findFilm</result>
		</action>
		<!-- 获取影片详情 -->
		<action name="detailFilm" class="filmAction" method="detailFilm">
			<result name="success">/manager/updateFilm.jsp</result>
		</action>
		<!-- 修改影片 -->
		<action name="updateFilm" class="filmAction" method="updateFilm">
			<result name="success" type="redirectAction">findFilm</result>
		</action>
		<!-- 删除影片 -->
		<action name="deleteFilm" class="filmAction" method="deleteFilm">
			<result name="success" type="redirectAction">findFilm</result>
		</action>
		
	</package>
	
</struts>

6、在WebRoot(页面路径下)创建文件夹manager，在manager下创建3个jsp文件：

films.jsp (查询页面)
insertFilm.jsp (添加影片页面)
updateFilm.jsp (修改影片页面)

6.1）films.jsp代码如下：

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%@taglib uri="/struts-tags" prefix="s" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>信息操作</title>
  </head>
  <body>
    <s:form action="/film/findFilm" method="post">
    	<s:submit value=" 获取所有影片信息 "></s:submit>
    </s:form>
    <a href="<%=basePath %>manager/insertFilm.jsp">添加影片信息</a><br />
    <s:if test="filmList != null">
    	<table border="1" width="40%">
    		<tr>
    			<th>序号</th><th>影片名</th><th>操作</th>
    		</tr>	
	    	<%-- 遍历影片信息 --%>
	    	<s:iterator var="film" value="filmList" status="st">
		    	<tr>
		    		<td><s:property value="#st.index+1" /></td>
		    		<td><s:property value="fname" /></td>
		    		<td>
		    			<s:url id="detailUrl" value="/film/detailFilm">
			                      		<s:param name="id" value="%{id}"/>
			                      	</s:url>
		    			<s:a href="%{detailUrl}">[修改]</s:a>&nbsp;
		    			<s:url id="deleteUrl" value="/film/deleteFilm">
			                      		<s:param name="id" value="%{id}"/>
			                      	</s:url>
		    			<s:a href="%{deleteUrl}">[删除]</s:a>
		    		</td>
		    	</tr>
			</s:iterator>
		</table>
    </s:if>
  </body>
</html>

6.2）insertFilm.jsp代码如下：

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%@taglib uri="/struts-tags" prefix="s" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>添加影片</title>
  </head>
  <body>
    <s:form action="/film/insertFilm" method="post">
    	<s:textfield name="fname" value="" />
    	<s:submit value=" 添加 "></s:submit>
    </s:form>
  </body>
</html>

6.3）updateFilm.jsp代码如下：

<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<%@taglib uri="/struts-tags" prefix="s" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>修改影片</title>
  </head>
  <body>
    <s:form action="/film/updateFilm" method="post">
    	<s:hidden name="id" />
    	<s:textfield name="fname" />
    	<s:submit value=" 修改 "></s:submit>
    </s:form>
  </body>
</html>
