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）
<&＃63;xml version="1.0" encoding="UTF-8"&＃63;>
classpath*:jdbc.properties
classpath*:/sqlMapConfig.xml
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）
<&＃63;xml version="1.0" encoding="UTF-8"&＃63;>
4、实体类sql配置文件User.xml（持久层）
<&＃63;xml version="1.0" encoding="UTF-8"&＃63;>insert into gy_user(USERID,USERNAME,PASSWORD) values(#userid#,#username#,#password#) delete from gy_user where USERID=#id# update gy_user set USERID=#userid#,USERNAME=#username#,PASSWORD=#password# where USERID=#userid#
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）
<&＃63;xml version="1.0" encoding="UTF-8" &＃63;>/success.jsp /userResult.jsp /success.jsp /userUpdate.jsp /success.jsp
7、web.xml配置文件
<&＃63;xml version="1.0" encoding="UTF-8"&＃63;>index.jsp contextConfigLocation classpath*:applicationContext.xml org.springframework.web.context.ContextLoaderListener struts org.apache.struts2.dispatcher.FilterDispatcher struts *.do struts *.action struts *.jsp
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 userlist=userService.queryUser(user);
System.out.println("userAction--size--"+userlist.size());
for(int i=0;i
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 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 queryUser(User user) throws Exception{
System.out.println("查询数据User开始--->UserService");
List userlist=userdao.queryUser(user);
System.out.println("UserService--size--"+userlist.size());
for(int i=0;iUserService");
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 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 queryUser(User user){
System.out.println("查询数据User开始--->UserDao"+"---"+user.getUserid()+"-"+user.getUsername()+"-"+user.getPassword());
List userlist=(List)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
2、query.jsp查询页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 用户ID：
3、userAdd.jsp添加用户页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
| 用户ID： | |
| 用户名： | |
| 密码： | |
4、userUpdate.jsp修改用户页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="com.user.model.User" ;%>
<%
User user=(User)session.getAttribute("result");
%>
| 用户ID： | |
| 用户名： | |
| 密码： | |
5、userResult.jsp用户列表
京公网安备 11010802041100号
