spring与struts2整合案例

整合时两个框架各自的分工如下：

  Struts2负责流程，Spring负责对象的创建，Action和Service都由Spring框架负责创建。这是常用的集成合并方案。

1：首先导入相关jar包，见如下图片：

2:web.xml所有代码如下：

<?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"><!-- 用于指定Spring的配置文件路径 --><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext.xml</param-value></context-param><!--服务器启动时，通过监听器初始化Spring的配置环境 监听器，默认加载文件是：/WEB-INF/applicationContext.xml--><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><!-- 配置Struts2框架的核心调度器 --><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><!-- 默认主界面 --><welcome-file-list><welcome-file>index.jsp</welcome-file></welcome-file-list></web-app>

3：在src目录下直接创建配置文件：applicationContext.xml和struts.xml

applicationContext.xml详细代码如下：

<beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd "><bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="locations"><list><value>classpath:Oracle.properties</value></list></property></bean><bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"destroy-method="close"><property name="driverClass" value="${jdbc.driverClass}" /><property name="jdbcUrl" value="${jdbc.jdbcUrl}" /><property name="user" value="${jdbc.user}" /><property name="password" value="${jdbc.password}" /></bean><bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"autowire="default"><property name="dataSource"><ref local="dataSource" /></property></bean><!-- 配置一个NamedParameterJdbcTemplate模板 使用构造函数注入器 --><bean id="namedjdbcTemplate"class="org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate"><constructor-arg ref="dataSource" /></bean><bean id="loginAction" class="com.sjx.action.LoginAction"autowire="byName" scope="prototype">         <property name="iLoginService" ref="loginService"></property></bean><bean id="loginService" class="com.sjx.service.impl.LoginServiceImpl"><property name="iloginDao" ref="loginDao"></property></bean><bean id="loginDao" class="com.sjx.dao.impl.LoginDaoImpl"><property name="namedjdbcTemplate" ref="namedjdbcTemplate"></property></bean></beans>

struts.xml详细代码如下：

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "dtds/struts-2.3.dtd"><struts><package name="com.sjx" namespace="/" extends="struts-default"><action name="Login" class="loginAction" method="login"><result name="success" type="redirect">/success.jsp</result><result name="login" type="redirect">/login.jsp</result></action></package></struts>    

由于此套整合包含调用oracle数据库进行操作，故还需引入数据库配置文件Oracle.properties，同样直接写在src目录下：

Oracle.properties：

jdbc.driverClass = oracle.jdbc.driver.OracleDriverjdbc.jdbcUrl = jdbc:oracle:thin:@localhost:1521/ORCLjdbc.user = scottjdbc.password = tiger

4：Action类：

package com.sjx.action;import java.util.List;import java.util.Map;import com.sjx.service.ILoginService;public class LoginAction {private ILoginService iLoginService;  public ILoginService getiLoginService() {return iLoginService;}public void setiLoginService(ILoginService iLoginService) {this.iLoginService = iLoginService;}    public String login(){  List<Map<String, Object>> list = iLoginService.find();  System.out.println(list);  return "success";  }}

dao包：包含接口和实现类：

接口（ILoginDao）：

package com.sjx.dao;import java.util.List;import java.util.Map;import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;public interface ILoginDao {/** * @return the namedjdbcTemplate */public abstract NamedParameterJdbcTemplate getNamedjdbcTemplate();/** * @param namedjdbcTemplate *            the namedjdbcTemplate to set */public abstract void setNamedjdbcTemplate(NamedParameterJdbcTemplate namedjdbcTemplate);    public abstract void add(String str);    public abstract List<Map<String, Object>> find();}

实现类（LoginDaoImpl）：

package com.sjx.dao.impl;import java.util.List;import java.util.Map;import org.springframework.jdbc.core.namedparam.NamedParameterJdbcTemplate;import com.sjx.dao.ILoginDao;import com.sjx.model.DeptVO;public class LoginDaoImpl implements ILoginDao {private NamedParameterJdbcTemplate namedjdbcTemplate;public void add(String str) {System.out.println("struts2+spring");}public NamedParameterJdbcTemplate getNamedjdbcTemplate() {return namedjdbcTemplate;}public void setNamedjdbcTemplate(NamedParameterJdbcTemplate namedjdbcTemplate) {this.namedjdbcTemplate = namedjdbcTemplate;}public List<Map<String, Object>>find() {DeptVO deptvo = null;String sql = "select * from dept";List<Map<String, Object>> list = namedjdbcTemplate.getJdbcOperations().queryForList(sql);return list;}}

实体类（DeptVO）：

package com.sjx.model;public class DeptVO {  private String deptNo;  private String dName;  private String loc;public String getDeptNo() {return deptNo;}public void setDeptNo(String deptNo) {this.deptNo = deptNo;}public String getdName() {return dName;}public void setdName(String dName) {this.dName = dName;}public String getLoc() {return loc;}public void setLoc(String loc) {this.loc = loc;}}

service接口和实现类：

接口（ILoginService）：

package com.sjx.service;import java.util.List;import java.util.Map;public interface ILoginService {  public abstract void add(String str);  public abstract List<Map<String, Object>> find();}

实现类（LoginServiceImpl）：

package com.sjx.service.impl;import java.util.List;import java.util.Map;import com.sjx.dao.ILoginDao;import com.sjx.service.ILoginService;public class LoginServiceImpl implements ILoginService {public ILoginDao iloginDao;public void add(String str) {iloginDao.add(str);}public ILoginDao getIloginDao() {return iloginDao;}public void setIloginDao(ILoginDao iloginDao) {this.iloginDao = iloginDao;}public List<Map<String, Object>> find() {List<Map<String, Object>> list = iloginDao.find();return list;}}

该套整合框架除了可以使用tomcat容器启动并进行初始化，还可以独自写一个类，在该类的main方法中进行初始化：

代码如下：

package com.sjx.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.sjx.action.LoginAction;public class SpringTest {/** * @param args */public static void main(String[] args) {       ApplicationContext ac =        new ClassPathXmlApplicationContext("applicationContext.xml");       LoginAction la = (LoginAction) ac.getBean("loginAction");   String aa = la.login();   System.out.println(aa);}}
