struts2+spring+ibatis框架整合实现增删改查

初步学习SSI框架，做的struts2+spring+ibatis框架整合的小实例，实现增删改查操作。

项目框架如下所示：

准备工作：导入需要的struts2、spring、ibatis的jar包，这里不一一列举了。

下面直接上完整的配置文件内容和代码，不说明先后步骤了

一、配置文件

1、spring配置文件applicationContext.xml（业务逻辑层）

<?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"
  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-2.5.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

<!-- 引入参数配置文件，数据库配置信息 -->
 <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
 <property name="locations">
 <list>
 <value>classpath*:jdbc.properties</value>
 </list>
 </property>
 </bean>

<!-- 数据源配制 -->
 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
 destroy-method="close">
 <property name="driverClassName" value="${jdbc.driverClassName}" />
 <property name="url" value="${jdbc.url}" />
 <property name="username" value="${jdbc.username}" />
 <property name="password" value="${jdbc.password}" />
 <property name="maxActive" value="20" />
 <property name="maxWait" value="1000" />
 <property name="testOnBorrow" value="true"/>
 <property name="testWhileIdle" value="true"/>
 <property name="validationQuery" value="select 1 from dual"/>
 <property name="poolPreparedStatements" value="true" />
 <property name="defaultAutoCommit" value="true" />
 </bean>

<!-- 注入ibatis配置文件 -->
 <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
 <property name="configLocations">
 <list>
 <value>classpath*:/sqlMapConfig.xml</value>
 </list>
 </property>
 <property name="dataSource" ref="dataSource" />
 </bean>
<!-- action -->
 <bean id="userAction" class="com.user.action.userAction" scope="prototype">
 <property name="userService" ref="userSI"></property>
 </bean>

<!-- service -->
 <bean id="userSI" class="com.user.service.impl.UserServiceImpl">
 <property name="userdao" ref="userDI" />
 </bean>

<!-- dao -->
 <bean id="userDI" class="com.user.dao.impl.UserDaoImpl">
 <property name="sqlMapClient" ref="sqlMapClient" />
 </bean>

 </beans>

2、数据库参数配置文件jdbc.properties

jdbc.driverClassName=oracle.jdbc.OracleDriver
jdbc.url=jdbc:oracle:thin:@198.10.3.138:1521:fapdb
jdbc.username=fapdb
jdbc.password=fapdb

3、ibatis配置文件sqlMapConfig.xml（持久层）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMapConfig PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
 "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<sqlMapConfig>
 <settings cacheModelsEnabled="true"
    enhancementEnabled="true"
    lazyLoadingEnabled="false"
    maxTransactions="32"
   maxRequests="512"
   maxSessions="128"
    useStatementNamespaces="false"/>

 <sqlMap resource="com/user/model/sqlmap/User.xml" /> 

</sqlMapConfig>

4、实体类sql配置文件User.xml（持久层）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap
  PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"
  "http://ibatis.apache.org/dtd/sql-map-2.dtd">
 <!-- 定义配置名 -->
<sqlMap namespace="User">
 <!-- <typeAlias alias="User" type="com.user.model.User"> </typeAlias> -->
 <resultMap id="userResultMap" class="com.user.model.User">
 <result property="userid" column="USERID" />
 <result property="username" column="USERNAME" />
 <result property="password" column="PASSWORD" />
 </resultMap>

<!-- 插入数据 -->
 <insert id="insertUser" parameterClass="com.user.model.User">
 insert into gy_user(USERID,USERNAME,PASSWORD) values(#userid#,#username#,#password#)
 </insert>
<!-- 查询数据 -->
 <select id="queryUser" parameterClass="com.user.model.User" resultClass="com.user.model.User">
 select USERID,USERNAME,PASSWORD from gy_user
 <dynamic prepend="where">
 <isNotEqual prepend="and" property="userid" compareValue="0">
 USERID=#userid#
 </isNotEqual>
 </dynamic>
 order by USERID
 </select>
<!-- 查询by id -->
 <select id="queryUserById" parameterClass="int" resultClass="com.user.model.User">
 select USERID,USERNAME,PASSWORD from gy_user where USERID=#id#
 </select>
<!-- 删除数据 -->
 <delete id="deleteUser" parameterClass="int">
 delete from gy_user where USERID=#id#
 </delete>
<!-- 更新数据 -->
 <update id="updateUser" parameterClass="com.user.model.User">
 update gy_user set USERID=#userid#,USERNAME=#username#,PASSWORD=#password# where USERID=#userid#
 </update>
</sqlMap>

5、struts参数配置文件struts.properties

### 默认编码
struts.i18n.encoding=UTF-8
### 使用spring装配工厂
struts.objectFactory = spring
struts.objectFactory.spring.autoWire = name
struts.objectFactory.spring.useClassCache = true
struts.multipart.parser=jakarta
struts.multipart.saveDir=/tmp
struts.multipart.maxSize=209715200
struts.action.extension=do
struts.serve.static=true
struts.serve.static.browserCache=true
struts.enable.DynamicMethodInvocation = true
struts.enable.SlashesInActionNames = false
struts.tag.altSyntax=true
struts.devMode = false
struts.i18n.reload=true
struts.ui.templateDir=template
struts.ui.templateSuffix=ftl
struts.configuration.xml.reload=ture
struts.ui.theme=simple
struts.velocity.configfile = velocity.properties
struts.url.http.port = 80
struts.url.https.port = 443
struts.url.includeParams = get
struts.dispatcher.parametersWorkaround = false
struts.freemarker.templatesCache=false
struts.freemarker.beanwrapperCache=false
struts.freemarker.wrapper.altMap=true
struts.xslt.nocache=false
struts.configuration.files=struts-default.xml,struts-plugin.xml,struts.xml
struts.mapper.alwaysSelectFullNamespace=false

6、struts配置文件struts.xml（控制层）

<?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>
 <span style="white-space:pre"> </span><package name="default" extends="struts-default">
 <span style="white-space:pre"> </span><!-- index_开头的action，调用action类中的*方法 -->
 <span style="white-space:pre"> </span><action name="index_*" class="userAction" method="{1}">
 <span style="white-space:pre"> </span><result name="success">/success.jsp</result>
 <span style="white-space:pre"> </span><result name="userResult">/userResult.jsp</result>
 <span style="white-space:pre"> </span><result name="successdelete">/success.jsp</result>
 <span style="white-space:pre"> </span><result name="querybyidRes">/userUpdate.jsp</result>
 <span style="white-space:pre"> </span><result name="successupdate">/success.jsp</result>
 <span style="white-space:pre"> </span></action>
 <span style="white-space:pre"> </span></package>
 </struts>

7、web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4"
 xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
 http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
 <welcome-file-list>
 <welcome-file>index.jsp</welcome-file>
 </welcome-file-list>

 <!-- 配置Spring -->
 <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath*:applicationContext.xml</param-value>
 </context-param>
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>

 <!-- 配置Struts -->
 <filter>
 <filter-name>struts</filter-name>
 <filter-class>
 org.apache.struts2.dispatcher.FilterDispatcher
 </filter-class>
 </filter>
 <filter-mapping>
 <filter-name>struts</filter-name>
 <url-pattern>*.do</url-pattern>
 </filter-mapping>
 <filter-mapping>
 <filter-name>struts</filter-name>
 <url-pattern>*.action</url-pattern>
 </filter-mapping>
 <filter-mapping>
 <filter-name>struts</filter-name>
 <url-pattern>*.jsp</url-pattern>
 </filter-mapping>
</web-app>

二、model模型层

实体类User.java

package com.user.model;

public class User {
 private int userid;
 private String username;
 private String password;

 public int getUserid() {
 return userid;
 }
 public String getUsername() {
 return username;
 }
 public String getPassword() {
 return password;
 }
 public void setUserid(int userid) {
 this.userid = userid;
 }
 public void setUsername(String username) {
 this.username = username;
 }
 public void setPassword(String password) {
 this.password = password;
 }

}

三、Action控制层

userAction.java类

package com.user.action;

import java.util.List;
import javax.servlet.http.HttpServletRequest;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.user.model.User;
import com.user.service.UserService;

public class userAction extends ActionSupport{
 HttpServletRequest request;
 private User user;
 private UserService userService;
 int id;

 public int getId() {
 return id;
 }

 public void setId(int id) {
 this.id = id;
 }

 public User getUser() {
 return user;
 }

 public void setUser(User user) {
 this.user = user;
 }

 public UserService getUserService() {
 return userService;
 }

 public void setUserService(UserService userService) {
 this.userService = userService;
 }

 public String insertUser() throws Exception{
 userService.insertUser(user);
 return "success";
 }
 //查询用户
 public String queryUser() throws Exception{
 List<User> userlist=userService.queryUser(user);
 System.out.println("userAction--size--"+userlist.size());
 for(int i=0;i<userlist.size();i++) {
  System.out.println("userAction--"+userlist.get(i).getUserid()+"-"+userlist.get(i).getUsername()+"-"+userlist.get(i).getPassword());
 }
 ActionContext.getContext().getSession().put("userresult", userlist);
 System.out.println("*****");
 return "userResult";
 }
 //删除用户
 public String deleteUser() throws Exception{
 System.out.println("userid:"+id);
 userService.deleteUser(id);
 return "successdelete";
 }
 //查询用户by id
 public String queryUserById() throws Exception{
 System.out.println("userid:"+id);
 User user=userService.queryUserById(id);
 System.out.println("--userAction--"+user.getUserid()+"--"+user.getUsername()+"--"+user.getPassword());
 ActionContext.getContext().getSession().put("result", user);
 return "querybyidRes";
 }
 //修改用户
 public String updateUser() throws Exception{
 userService.updateUser(user);
 return "successupdate";
 }

}

四、Service接口+实现（业务逻辑层）

1、Service接口

UserService.java类

package com.user.service;

import java.util.List;
import com.user.model.User;

public interface UserService {
 //添加用户
 public void insertUser(User user) throws Exception;
 //查询用户
 public List<User> queryUser(User user) throws Exception;
 //查询用户by id
 public User queryUserById(int id) throws Exception;
 //删除用户
 public void deleteUser(int id) throws Exception;
 //修改用户
 public void updateUser(User user) throws Exception;
}

2、Service接口实现

UserServiceImpl.java类

package com.user.service.impl;

import java.util.List;
import com.user.model.User;
import com.user.service.UserService;
import com.user.dao.UserDao;

public class UserServiceImpl implements UserService{
 private UserDao userdao=null;
 public UserDao getUserdao() {
 return userdao;
 }

 public void setUserdao(UserDao userdao) {
 this.userdao = userdao;
 }
 //添加用户
 public void insertUser(User user) throws Exception {
 // TODO Auto-generated method stub
 System.out.println("插入数据User开始--->UserService");
 userdao.insertUser(user);
 System.out.println("插入数据User结束--->UserService");
 }
 //查询用户
 public List<User> queryUser(User user) throws Exception{
 System.out.println("查询数据User开始--->UserService");
 List<User> userlist=userdao.queryUser(user);
 System.out.println("UserService--size--"+userlist.size());
 for(int i=0;i<userlist.size();i++) {
  System.out.println("UserService--"+userlist.get(i).getUserid()+"-"+userlist.get(i).getUsername()+"-"+userlist.get(i).getPassword());
 }
 System.out.println("查询数据User结束--->UserService");
 return userlist;
 }
 //删除用户
 public void deleteUser(int id) throws Exception {
 // TODO Auto-generated method stub
 System.out.println("删除数据User开始--->UserService");
 userdao.deleteUser(id);
 System.out.println("删除数据User开始--->UserService");
 }
 //查询用户by id
 public User queryUserById(int id) throws Exception {
 // TODO Auto-generated method stub
 System.out.println("查询数据BY ID开始--->UserService"+"---"+id);
 User user=userdao.queryUserById(id);
 System.out.println("查询数据BY ID结束--->UserService"+"---"+id);
 return user;
 }
 //修改用户
 public void updateUser(User user) throws Exception {
 // TODO Auto-generated method stub
 System.out.println("更新数据User开始--->UserService");
 userdao.updateUser(user);
 System.out.println("更新数据User开始--->UserService");
 }

}

五、DAO接口+实现（持久层）

1、DAO接口

UserDao.java类

package com.user.dao;
import java.util.List;
import com.user.model.User;;

public interface UserDao {
 //添加用户
 public void insertUser(User user);
 //查询用户
 public List<User> queryUser(User user);
 //查询用户by id
 public User queryUserById(int id);
 //删除用户
 public void deleteUser(int id);
 //修改用户
 public void updateUser(User user);
}

2、DAO接口实现

UserServiceImpl.java类

package com.user.dao.impl;

import java.util.List;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;
import com.user.dao.UserDao;
import com.user.model.User;

public class UserDaoImpl extends SqlMapClientDaoSupport implements UserDao{
 //添加用户
 public void insertUser(User user ){
 System.out.println("插入数据User开始--->UserDao"+"---"+user.getUserid()+"-"+user.getUsername()+"-"+user.getPassword());
 this.getSqlMapClientTemplate().insert("insertUser",user);
 System.out.println("插入数据User结束--->UserDao");
 }
 //查询用户
 public List<User> queryUser(User user){
 System.out.println("查询数据User开始--->UserDao"+"---"+user.getUserid()+"-"+user.getUsername()+"-"+user.getPassword());
 List<User> userlist=(List<User>)this.getSqlMapClientTemplate().queryForList("queryUser", user);
 System.out.println("查询数据User结束--->UserDao");
 return userlist;
 }
 //删除用户
 public void deleteUser(int id) {
 System.out.println("删除数据User开始--->UserDao"+"---"+id);
 this.getSqlMapClientTemplate().delete("deleteUser", id);
 System.out.println("删除数据User结束--->UserDao"+"---"+id);
 }
 //查询用户by id
 public User queryUserById(int id) {
 System.out.println("查询数据BY ID开始--->UserDao"+"---"+id);
 User user=(User)this.getSqlMapClientTemplate().queryForObject("queryUserById", id);
 System.out.println("查询数据BY ID结束--->UserDao"+"---"+id);
 return user;
 }
 //修改用户
 public void updateUser(User user) {
 System.out.println("更新数据User开始--->UserDao"+"---"+user.getUserid());
 this.getSqlMapClientTemplate().update("updateUser", user);
 System.out.println("更新数据User结束--->UserDao"+"---"+user.getUserid());
 }
}

六、JSP文件（表示层）

1、index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

5、userResult.jsp用户列表

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="com.user.model.User" ;%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
 </head>

 <body>
 <%
 List<User> userlist=(List<User>)session.getAttribute("userresult");
 System.out.println("userResult.jsp--size--"+userlist.size());
 for(int i=0;i<userlist.size();i++) {
 System.out.println("userResult.jsp--"+userlist.get(i).getUserid()+"-"+userlist.get(i).getUsername()+"-"+userlist.get(i).getPassword());
