使用idea15搭建基于maven的springmvc-mybatis框架
我这边使用的是intellij idea15
1.new maven webapp project
2.添加groupId和artifactId
3.选择maven路径和maven仓库路径
最后确定之后，等1分钟左右时间，maven会自动补全项目结构。如果没有，自己新建src/main/java等结构吧
4.pom.xml中添加依赖包

然后在src/main/resoures目录下分别新建配置文件目录：spring、mybatis、springmvc、properties
配置spring文件：在sping目录下新建applicationContext.xml：

添加数据源类com.mlxs.mvc.common.MutipleDataSource：
package com.mlxs.mvc.common; import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource; /**

dataSourceKey.set(dataSource);
} @Override
protected Object determineCurrentLookupKey() {
return dataSourceKey.get();
} }
在mybatis目录下添加mybatis-config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC

<mappers>
<!--这里不需要添加mapper.xml文件，在spring的sqlSessionFactory中已经配置了自动扫描-->
</mappers>
</configuration>
在spingmvc目录下添加spring-mvc.xml:

在properties目录下添加jdbc.properties和log4j.properties文件：

好了，现在所有的配置都完成了，下面就是写model、dao(我这里是mapper，对应mybatis的mapper类)、service、controller类：
1.com.mlxs.mvc.model.User：
package com.mlxs.mvc.model; /**
* User:
*
* @author yangzhenlong
* @since 2016/7/13
*/
public class User {
private int id;
private String loginName;
private String loginPwd;
private String realName;
private int sex;
private int age;
private String phone;
private String address;
private String remark; public int getId() {
return id;
} public void setId(int id) {
this.id = id;
} public String getLoginName() {
return loginName;
} public void setLoginName(String loginName) {
this.loginName = loginName;
} public String getLoginPwd() {
return loginPwd;
} public void setLoginPwd(String loginPwd) {
this.loginPwd = loginPwd;
} public String getRealName() {
return realName;
} public void setRealName(String realName) {
this.realName = realName;
} public int getSex() {
return sex;
} public void setSex(int sex) {
this.sex = sex;
} public int getAge() {
return age;
} public void setAge(int age) {
this.age = age;
} public String getPhone() {
return phone;
} public void setPhone(String phone) {
this.phone = phone;
} public String getAddress() {
return address;
} public void setAddress(String address) {
this.address = address;
} public String getRemark() {
return remark;
} public void setRemark(String remark) {
this.remark = remark;
}
}
2.com.mlxs.mvc.mapper.UserMapper：
package com.mlxs.mvc.mapper; import com.mlxs.mvc.model.User; import java.util.List; /**
* UserMapper:
*
* @author yangzhenlong
* @since 2016/7/13
*/
public interface UserMapper {
public int save(User user);
public int delete(int id);
public int update(User user);
public User queryByUser(User user);
public List<User> queryAll();
}
3.com.mlxs.mvc.service.UserService
package com.mlxs.mvc.service; import com.mlxs.mvc.model.User; import java.util.List; /**
* UserService:
*
* @author yangzhenlong
* @since 2016/7/13
*/
public interface UserService { public List<User> queryAll();
}
3.1com.mlxs.mvc.service.impl.UserServiceImpl
package com.mlxs.mvc.service.impl; import com.mlxs.mvc.mapper.UserMapper;
import com.mlxs.mvc.model.User;
import com.mlxs.mvc.service.UserService;
import org.springframework.stereotype.Service; import javax.annotation.Resource;
import java.util.List; /**

*/
@Service
public class UserServiceImpl implements UserService { @Resource
UserMapper userMapper;
public List<User> queryAll() {
return userMapper.queryAll();
}
}
4.com.mlxs.mvc.controller.UserController：
package com.mlxs.mvc.controller; import com.mlxs.mvc.model.User;
import com.mlxs.mvc.service.UserService;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod; import javax.annotation.Resource;
import java.util.List; /**
* UserController:
*
* @author yangzhenlong
* @since 2016/7/13
*/
@Controller
@RequestMapping("/user")
public class UserController {
@Resource
UserService userService; @RequestMapping(value = "/list", method = {RequestMethod.GET, RequestMethod.POST})
public String list(ModelMap modelMap){
List<User> userList = userService.queryAll();
modelMap.addAttribute("userList", userList);
return "userlist";
}
}
然后要添加mapper类对应的maper.xml文件：在resources/mybatis目录下添加：com.mlxs.mvc.mapper目录，然后新建：UserMapper.xml：
<?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.mlxs.mvc.mapper.UserMapper">
<insert id="save" parameterType="com.mlxs.mvc.model.User">
INSERT INTO `test`.`user`(`id`,`login_name`,`login_pwd`,`real_name`,`sex`,`age`,`phone`,`address`,`remark`)
VALUES ( NULL,
#{loginName},#{loginPwd},#{realName},#{sex},#{age},#{phone},#{address},#{remark});
</insert> <select id="queryAll" resultType="com.mlxs.mvc.model.User">
SELECT id,
login_name loginName,
login_pwd loginPwd,
real_name realName,
sex,
age,
phone,
address,
remark
FROM test.user
</select>
</mapper>
对应的数据表DDL语句：
CREATE TABLE `user` (
`id` int(8) NOT NULL AUTO_INCREMENT,
`login_name` varchar(64) DEFAULT NULL,
`login_pwd` varchar(64) DEFAULT NULL,
`real_name` varchar(64) DEFAULT NULL,
`sex` tinyint(2) DEFAULT NULL COMMENT '性别（1男，2女）',
`age` int(3) DEFAULT NULL COMMENT '年龄',
`phone` varchar(11) DEFAULT NULL COMMENT '电话',
`address` varchar(128) DEFAULT NULL COMMENT '地址',
`remark` text COMMENT '备注',
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8
表中添加数据：
最后，在WEB-INF目录下新建jsp目录，再新建userlist.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
<title>用户列表</title>
<style>
table tr td{
width:100px;
}
</style>
</head>
<body>
用戶列表頁面
<table style="border:1px solid red;background-color:#eee;"> <tr width="100%">
<td>Id</td>
<td>登录名</td>
<td>密码</td>
<td>姓名</td>
<td>性别</td>
<td>年龄</td>
<td>电话</td>
<td>地址</td>
<td>备注</td>
</tr>
<c:forEach items="${userList}" var="user">
<tr>
<td>${user.id}</td>
<td>${user.loginName}</td>
<td>${user.loginPwd}</td>
<td>${user.realName}</td>
<td>${user.sex==1?'男':'女'}</td>
<td>${user.age}</td>
<td>${user.phone}</td>
<td>${user.address}</td>
<td>${user.remark}</td>
</tr>
</c:forEach>
</table>
</body>
</html>
配置server，启动tomcat，访问controller地址：http://localhost:8080/user/list，查看结果：
