以下是通過eclipse創(chuàng)建基于maven的ssm web項(xiàng)目完整步驟
File -> New->Maven Project(沒有選項(xiàng)，參照：eclipse右鍵New添加Maven Project)
2. 生成結(jié)果如下：
3. 配置Maven
添加Source文件夾
接下來需要添加
src/main/java
src/test/java
src/test/resources三個(gè)文件夾
右鍵項(xiàng)目根目錄點(diǎn)擊New -> Source Folder，
建出這三個(gè)文件夾。注意不是建普通的Folder，而是Source Folder。
項(xiàng)目或者文件加上右鍵 new sourceFolder,正常情況下是沒有問題的
如果出現(xiàn)了下面的這情況,其實(shí)是真的存在的只是我們看不到
項(xiàng)目右鍵屬性->Java Build Path
Apply -> Apply and Close-> Ok
設(shè)置好了之后發(fā)現(xiàn), 發(fā)現(xiàn) src/main/java就可以看到了
4. 搭建Spring + SpringMVC +MyBatis框架
修改pom.xml后保存會(huì)自動(dòng)下載, Maven引入項(xiàng)目用到的jar包
pom.xml文件如下：

6. 創(chuàng)建數(shù)據(jù)庫(kù)及表格
CREATE DATABASE `ssmone` CHARACTER SET 'utf8' COLLATE 'utf8_general_ci'; CREATE TABLE `user` ( `uid` tinyint(2) NOT NULL, `uname` varchar(20) DEFAULT NULL, `usex` varchar(10) DEFAULT NULL, PRIMARY KEY (`uid`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
7. 創(chuàng)建一個(gè)持久化類
在src/main/java/下創(chuàng)建一個(gè)名為com.ncyteng.po的包, 并在該包中創(chuàng)建一個(gè)MyUser類
代碼如下：
package com.ncyteng.po;
public class MyUser {
private Integer uid;
private String uname;
private String usex;
public Integer getUid() {
return uid;
}
public void setUid(Integer uid) {
this.uid = uid;
}
public String getUname() {
return uname;
}
public void setUname(String uname) {
this.uname = uname;
}
public String getUsex() {
return usex;
}
public void setUsex(String usex) {
this.usex = usex;
}
@Override
public String toString() { // 為了方便查看結(jié)果，重寫了toString方法
return "User[uid=" + uid + ",uname=" + uname + ",usex=" + usex + "]";
}
}8. 創(chuàng)建dao層
在src/main/java/下創(chuàng)建一個(gè)名為com.ncyteng.dao的包, 并在該包中創(chuàng)建一個(gè)UserDao的接口
代碼如下：
package com.ncyteng.dao;
import java.util.List;
import org.apache.ibatis.annotations.Mapper;
import org.springframework.stereotype.Repository;
import com.ncyteng.po.MyUser;
@Repository("userDao")
@Mapper
/*
* 使用Spring自動(dòng)掃描MyBatis的接口并裝配 （Spring將指定包中所有被注解標(biāo)注的接口自動(dòng)裝配為Mybatis的映射接口
*/
public interface UserDao {
/**
* 接口方法對(duì)應(yīng)的SQL映射文件UserMapper.xml中的id
*/
public MyUser selectUserById(Integer uid);
public List<MyUser> selectAllUser();
public int addUser(MyUser user);
public int updateUser(MyUser user);
public int deleteUser(Integer uid);
}9. 在src/main/resources下創(chuàng)建mybatis.mapper包, 并在里面創(chuàng)建UserMapper.xml，內(nèi)容如下
<?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.ncyteng.dao.UserDao">
<!--根據(jù)uid查詢一個(gè)用戶信息 -->
<select id="selectUserById" parameterType="Integer" resultType="com.ncyteng.po.MyUser">
select * from user where uid = #{uid}
</select>
<!-- 查詢所有用戶信息 -->
<select id="selectAllUser" resultType="com.ncyteng.po.MyUser">
select * from user
</select>
<!-- 添加一個(gè)用戶，#{uname}為 com.mybatis.po.MyUser 的屬性值 -->
<insert id="addUser" parameterType="com.ncyteng.po.MyUser">
insert into user (uname,usex) values(#{uname},#{usex})
</insert>
<!--修改一個(gè)用戶 -->
<update id="updateUser" parameterType="com.ncyteng.po.MyUser">
update user set uname = #{uname},usex = #{usex} where uid = #{uid}
</update>
<!-- 刪除一個(gè)用戶 -->
<delete id="deleteUser" parameterType="Integer">
delete from user where uid = #{uid}
</delete>
</mapper>10. 在src/main/java/下創(chuàng)建com.ncyteng.controller包，并創(chuàng)建控制器UserController, 代碼如下：
package com.ncyteng.controller;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import com.ncyteng.dao.UserDao;
import com.ncyteng.po.MyUser;
@Controller("userController")
public class UserController {
@Autowired
private UserDao userDao;
@RequestMapping("/select")
public String test(Model model) {
// 查詢一個(gè)用戶
MyUser auser = userDao.selectUserById(1);
System.out.println(auser);
System.out.println("============================");
// 添加一個(gè)用戶
MyUser addmu = new MyUser();
addmu.setUname("莊子");
addmu.setUsex("男");
int add = userDao.addUser(addmu);
System.out.println("添加了" + add + "條記錄");
System.out.println("============================");
// 修改一個(gè)用戶
MyUser updatemu = new MyUser();
updatemu.setUid(1);
updatemu.setUname("老子");
updatemu.setUsex("男");
int up = userDao.updateUser(updatemu);
System.out.println("修改了" + up + "條記錄");
System.out.println("============================");
// 刪除一個(gè)用戶
int dl = userDao.deleteUser(1);
System.out.println("刪除了" + dl + "條記錄");
System.out.println("============================");
// 查詢所有用戶
List<MyUser> list = userDao.selectAllUser();
for (MyUser myUser : list) {
System.out.println(myUser);
}
List<MyUser> list1 = userDao.selectAllUser();
model.addAttribute("userList", list1);
return "user/userList";
}
}11. 在src/main/webapp/WEB-INF/下建views/user文件夾，并在下面建userList.jsp文件，內(nèi)容如下
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<br>
<c:forEach items="${userList }" var="user">
${user.uid }
${user.uname }

</body>
</html>12. 最終結(jié)構(gòu)如下：
