      	<url-pattern>/*</url-pattern>
      </filter-mapping>
      <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
      </welcome-file-list>
    </web-app>

四、配置applicationContext.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"

               http://www.springframework.org/schema/context/spring-context-3.2.xsd">
    	
    	<context:annotation-config />
    	
    	<context:component-scan base-package="com.frame"></context:component-scan>
    	
    	<bean id="propertyPlaceholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    		<property name="locations">
    			<list>

    	</bean>
    	
    	
    	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    		<property name="dataSource" ref="dataSource" />
    		<property name="configLocation" value="/WEB-INF/mybatis.xml"></property>
    	</bean>

    	</bean>
    	
    	
    	<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    		<property name="dataSource" ref="dataSource"/>
    	</bean>
    	
    	
    	<jdbc:initialize-database data-source="dataSource" ignore-failures="NONE" enabled="${jdbc.initializedatabase}">
    		<jdbc:script encoding="utf-8" location="/WEB-INF/db-init.sql"/>
    	</jdbc:initialize-database>
    </beans>

五、配置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.i18n.encoding" value="UTF-8"/>
    	
    	<constant name="struts.configuration.xmlreload" value="true"/>
    		
    	<constant name="struts.devMode" value="true"/>
    	
    	<constant name="struts.ui.theme" value="xhtml"/>
    	
    	<package name="test" namespace="/" extends="struts-default">
    		<action name="hello" class="com.frame.action.HelloAction">
    			<result name="success">/pages/hello.jsp</result>
    		</action>
    		<action name="demo" class="demoAction">
    		</action>
    	</package>
    </struts>

六、配置log4j.properties

log4j.rootLogger=info,A1
    log4j.logger.com.mchange=warn,A1
    log4j.additivity.com.mchange=false
    log4j.logger.org.hibernate=warn,A1
    log4j.additivity.org.hibernate=false
    log4j.logger.com.ibatis=warn,A1
    log4j.additivity.com.ibatis=false
    # ConsoleAppender
    log4j.appender.A1=org.apache.log4j.ConsoleAppender
    log4j.appender.A1.layout=org.apache.log4j.PatternLayout
    log4j.appender.A1.layout.ConversionPattern=%-d{yyyy-MM-dd HH\:mm\:ss,SSS} [%c]-[%p] %m%n
    # 打印sql
    log4j.logger.org.apache.ibatis=debug
    log4j.logger.java.sql.Connection=debug
    log4j.logger.java.sql.Statement=debug
    log4j.logger.java.sql.PreparedStatement=debug
    log4j.logger.java.sql.ResultSet=debug
    #com.frame
    log4j.logger.com.frame=debug

七、建表及序列sql文件db-init.sql内容

create table DEMO
    (
      ID          NUMBER,
      NAME        VARCHAR2(50),
      GENDER      VARCHAR2(1),
      AGE         NUMBER,
      CREATE_DATE DATE,
      UPDATE_DATE DATE
    );
    create sequence DEMO_SEQ
    minvalue 1
    maxvalue 999999999999999999999999999
    start with 21
    increment by 1
    cache 20;

八、配置mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
    <configuration>
    	<typeAliases>
    	</typeAliases>
    	<mappers>
    		<mapper resource="com/frame/dao/demoMapper.xml"/>
    	</mappers>
    </configuration>

九、数据库属性文件db.properties内容

#######################datasource config################################
    #for oracle
    database.driver=oracle.jdbc.driver.OracleDriver
    database.url=jdbc:oracle:thin:@127.0.0.1:1521:xe
    database.username=test
    database.password=test
    
    #######################pool config################################
    database.initialSize=2
    database.maxActive=10
    database.maxIdle=5
    database.minIdle=3
    database.maxWait=3000
    
    #######################jdbc:initialize-database enabled config################################
    jdbc.initializedatabase=false

**测试一下struts：**

一、建立一个类：com.frame.action.HelloAction，内容如下：

package com.frame.action;
    
    import java.io.IOException;
    import java.io.PrintWriter;
    
    import javax.servlet.http.HttpServletResponse;
    
    import org.apache.struts2.interceptor.ServletResponseAware;
    
    import com.opensymphony.xwork2.ActionSupport;
    
    public class HelloAction extends ActionSupport implements ServletResponseAware{
    	private static final long serialVersionUID = -6493858961444458651L;
    	private HttpServletResponse response;
    	@Override
    	public void setServletResponse(HttpServletResponse response) {
    		this.response = response;
    	}
    	@Override
    	public String execute() throws Exception {
    		System.out.println("HelloAction.execute is executing...");
    		return SUCCESS;
    	}
    	public void say() throws IOException{
    		System.out.println("HelloAction.say is executing....");
    		response.setContentType("text/html;charset=utf-8");
    		PrintWriter out = response.getWriter();
    		out.println("<span style='color:red;'>啊哈，We are here!</span>");
    		out.close();
    	}
    	
    }

二、建一个响应jsp：/zframe/WebRoot/pages/hello.jsp，内容如下：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    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>
        <base href="<%=basePath%>">
        
        <title>My JSP 'hello.jsp' starting page</title>
        
    	<meta http-equiv="pragma" content="no-cache">
    	<meta http-equiv="cache-control" content="no-cache">
    	<meta http-equiv="expires" content="0">    
    	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    	<meta http-equiv="description" content="This is my page">
    	
    
      </head>
      
      <body>
      	<h1 style="color:#aabbff;">欢迎使用struts2。。。</h1>
      </body>
    </html>

三、测试结果：

![Image 1][]![SouthEast 1][]

![SouthEast 2][]

![Image 1][]

**测试一下mybatis：**  
一、建立一个action类

package com.frame.action;
    
    import java.util.HashMap;
    import java.util.Map;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.context.annotation.Scope;
    import org.springframework.stereotype.Controller;
    
    import com.frame.service.DemoService;
    import com.opensymphony.xwork2.ActionSupport;
    
    @Controller
    @Scope("prototype")
    public class DemoAction extends ActionSupport {
    	private static final long serialVersionUID = -3617424650852024180L;
    	@Autowired
    	private DemoService demoService;
    	private String name;
    	private String gender;
    	private int age;
    	
    	public void insert() {
    		System.out.println("开始执行插入数据。。。");
    		Map map = new HashMap();
    		map.put("name", name);
    		map.put("gender", gender);
    		map.put("age", age);
    		this.demoService.insert(map);
    		System.out.println("插入数据成功："+map);
    	}
    	
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public String getGender() {
    		return gender;
    	}
    	public void setGender(String gender) {
    		this.gender = gender;
    	}
    	public int getAge() {
    		return age;
    	}
    	public void setAge(int age) {
    		this.age = age;
    	}
    	
    }

二，建立一个service接口并建其实现类：

a.接口

package com.frame.service;
    
    import java.util.Map;
    
    public interface DemoService {
    
    	public void insert(Map map);
    
    }

b.实现类

package com.frame.service.impl;
    
    import java.util.Map;
    
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    
    import com.frame.dao.DemoDao;
    import com.frame.service.DemoService;
    
    @Service
    public class DemoServiceImpl implements DemoService {
    	@Autowired
    	private DemoDao demoDao;
    	
    	@Override
    	public void insert(Map map) {
    		this.demoDao.insert(map);
    	}
    }

三、建立Dao接口和其对应的mapper文件

a.dao接口

package com.frame.dao;
    
    import java.util.Map;
    
    import org.springframework.stereotype.Repository;
    import org.springframework.transaction.annotation.Transactional;
    
    @Repository
    @Transactional
    public interface DemoDao {
    
    	public void insert(Map map);
    
    }

b.demoMapper.xml内容

<?xml version="1.0" encoding="utf-8" ?>
    <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
    <mapper namespace="com.frame.dao.DemoDao">
    	<insert id="insert">
    		insert into demo (
    			id,
    			name,
    			gender,
    			age,
    			create_date) 
    		values(
    			demo_seq.nextval,
    			#{name,jdbcType=VARCHAR},
    			#{gender,jdbcType=VARCHAR},
    			#{age,jdbcType=NUMERIC},
    			sysdate)
    	</insert>
    </mapper>

c.demoMapper.xml说明

demoMapper.xml的路径配置在mybatis.xml文件中。其内的sql需要一个namespace，用来指定它是哪个dao的sql。如：其内id为insert的sql对应com.frame.dao.DemoDao接口的insert方法。当然这种配置是mybatis中的一种，如需要了解更多，请查询mybatis的文档。

四、jsp表单文件/zframe/WebRoot/pages/demo.jsp内容

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
    <%
    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>
        <base href="<%=basePath%>">
        
        <title>My JSP 'demo.jsp' starting page</title>
        
    	<meta http-equiv="pragma" content="no-cache">
    	<meta http-equiv="cache-control" content="no-cache">
    	<meta http-equiv="expires" content="0">    
    	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
    	<meta http-equiv="description" content="This is my page">
    	
    
      </head>
      
      <body>
        <form action="demo!insert.action">
        	姓名：<input name="name"><br>
        	性别：<input type="radio" name="gender" value="1">男<input type="radio" name="gender" value="2">女<br>
        	年龄：<input name="age" οnkeyup="this.value=this.value.replace(/[^0-9]/g,'');"><br>
        	<input type="submit" value="确定">
        </form>
      </body>
    </html>
