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"

<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="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"> <html> <head> </head> <body> <a href="userAdd.jsp" rel="external nofollow" >添加用户</a><br> <a href="query.jsp" rel="external nofollow" >查询/管理用户</a> </body> </html>
2、query.jsp查询页面

<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());
}
%>
<table border="1">
