2、jndi配置

<?xml version="1.0" encoding="UTF-8"?>
<context>
<Resource
name="jdbc/hss"
type="javax.sql.DataSource"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://localhost:5432/mydb"
validationQuery="select version()"
username="postgres"
password="123456"
maxWait="50"
maxIdle="2"
maxActive="4" />
</context>

3、spring-config.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-3.0.xsd">

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName" value="java:comp/env/jdbc/hss" />
</bean>

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
</bean>

<bean id="txTemplate" class="org.springframework.transaction.support.TransactionTemplate">
<property name="transactionManager" ref="transactionManager"></property>
<property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"></property>
</bean>

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.guorui.mybatis.dao" />
</bean>

<bean id="fooService" class="com.guorui.app.FooService">
<property name="tbUserMapper" ref="tbUserMapper" />
<property name="txTemplate" ref="txTemplate" />
</bean>

</beans>

4、得到的service

package com.guorui.app;

import org.springframework.transaction.TransactionStatus;
import org.springframework.transaction.support.TransactionCallback;
import org.springframework.transaction.support.TransactionTemplate;

import com.guorui.mybatis.dao.TbUserMapper;
import com.guorui.mybatis.model.TbUser;

public class FooService {

private TransactionTemplate txTemplate;
private TbUserMapper tbUserMapper;

public void setTbUserMapper(TbUserMapper tbUserMapper) {
this.tbUserMapper = tbUserMapper;
}

public void setTxTemplate(TransactionTemplate txTemplate) {
this.txTemplate = txTemplate;
}

// spring的手动事务管理
public void doSomeBusinessStuff_man(final Long userId) {
txTemplate.execute(new TransactionCallback<Boolean>(){
public Boolean doInTransaction(TransactionStatus status){
try {
TbUser record = new TbUser();
record.setTu002("0003");
record.setTu003("郭一鸣22"+userId);
FooService.this.tbUserMapper.insert(record);
System.out.println(record.getTu001());
} catch (Exception e) {
status.setRollbackOnly();//
e.printStackTrace();
return false;
}
return true;
}
});
}
// spring的自动事务管理
public void doSomeBusinessStuff_auto(final Long userId) {
TbUser record = new TbUser();
record.setTu002("0003");
record.setTu003("郭一鸣22"+userId);
FooService.this.tbUserMapper.insert(record);
System.out.println(record.getTu001());

}
}

5、在servlet中调研spring中的service

package com.guorui.app;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Calendar;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

import com.guorui.mybatis.dao.TbUserMapper;

public class GuoTestBS extends HttpServlet {

private static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
queryTest(response);
}

private void queryTest(HttpServletResponse response) throws IOException {
response.setCharacterEncoding("UTF8");
response.setContentType("text/html; charset=UTF-8");
PrintWriter writer = response.getWriter();
ServletContext application;
WebApplicationContext wac;
application = getServletContext();
wac = WebApplicationContextUtils.getWebApplicationContext(application);
FooService fooService = (FooService)wac.getBean("fooService");
fooService.doSomeBusinessStuff_man(Long.valueOf(2));
writer.print(Calendar.getInstance().toString());
writer.close();
}

}

===============================开始struts整合spring============================================

6、在web.xml里面配置struts2用到的核心过滤器。

<filter>  
    <filter-name>struts2</filter-name>  
    <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>  
</filter>  
<filter-mapping>  
    <filter-name>struts2</filter-name>  
    <url-pattern>/*</url-pattern>  
</filter-mapping>  

7、测试struts2和spring整合对不对?
写一个jsp页面index.jsp来测试:

Html代码  
<%@ 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>  
    <s:form action="Login" method="post">  
        <s:textfield name="userName" label="userName"></s:textfield>  
        <s:password name="password" label="password"></s:password>  
        <s:submit label="submit"></s:submit>  
    </s:form>  
</body>  
</html>  

第二个jsp页面result.jsp来测试结果:

Html代码  
<%@ 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>  <s:property value="result"/>
 
</body>  
</html>  

8、struts2的action

package com.guorui.struts.action;

import com.guorui.app.FooService;
import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

private static final long serialVersionUID = -829916501012605182L;
// input
private String userName;
private String password;
// output
private String result;
// tools
private FooService fooService;

public void setFooService(FooService fooService) {
this.fooService = fooService;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
@Override
public String execute() throws Exception {
if(fooService.doSomeBusinessStuff_man(Long.valueOf(100))) {
result = "goooooood";
return SUCCESS;
} else {
result = "nooooooot";
return INPUT;
}
}
}

9、在spring-config..xml里面配置:

<bean id="loginActionBean" class="com.guorui.struts.action.LoginAction" scope="prototype">
<property name="fooService" ref="fooService"></property>
</bean>

10、在struts.xml里面配置: 
Xml代码  
<package name="struts2" extends="struts-default">  
    <action name="Login" class="loginActionBean">  // 这里的class就是上面的bean id
        <result name="success">/result.jsp</result>  
        <result name="input">/login.jsp</result>  
    </action>  
</package>
