1、pom文件添加依赖
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>

</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<fork>true</fork>
</configuration>
</plugin>
</plugins>
</build>
2、修改resources包下的application.properties文件
#mapper自动扫描
mybatis.type-aliases-package=com.huaxun.springboot.mapper
#数据库信息
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/test1?useUnicode=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = root
#添加jsp支持，制定页面跳转的文件加和文件后缀
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
3、在entity包下新建User类，并在数据新建对应的表
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
`id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT '主键id',
`userName` varchar(32) DEFAULT NULL COMMENT '用户名',
`passWord` varchar(32) DEFAULT NULL COMMENT '密码',
`user_sex` varchar(32) DEFAULT NULL,
`nick_name` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=50 DEFAULT CHARSET=utf8;
public class User {
private int id;
private String userName;
private String passWord;
private String userSex;
private String nickName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
public String getUserSex() {
return userSex;
}
public void setUserSex(String userSex) {
this.userSex = userSex;
}
public String getNickName() {
return nickName;
}
public void setNickName(String nickName) {
this.nickName = nickName;
}
}
4、在resouces包下新建mybatis包，并在mybatis包下新建mybatis-config.xml文件
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<typeAliases>
<typeAlias alias="Integer" type="java.lang.Integer" />
<typeAlias alias="Long" type="java.lang.Long" />
<typeAlias alias="HashMap" type="java.util.HashMap" />
<typeAlias alias="LinkedHashMap" type="java.util.LinkedHashMap" />
<typeAlias alias="ArrayList" type="java.util.ArrayList" />
<typeAlias alias="LinkedList" type="java.util.LinkedList" />
</typeAliases>
</configuration>
5、在刚刚新建的mybatis包下，再新建mapper包，并在mapper包下新建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.huaxun.springboot.mapper.UserMapper" >
<resultMap id="BaseResultMap" type="com.huaxun.springboot.entity.User" >
<id column="id" property="id" jdbcType="BIGINT" />
<result column="userName" property="userName" />
<result column="passWord" property="passWord" />
<result column="user_sex" property="userSex" />
<result column="nick_name" property="nickName" />
</resultMap>
<sql id="Base_Column_List" >
id, userName, passWord, user_sex, nick_name
</sql>
<select id="getAll" resultMap="BaseResultMap" >
SELECT
<include refid="Base_Column_List" />
FROM users
</select>
<select id="getOne" parameterType="java.lang.Long" resultMap="BaseResultMap" >
SELECT
<include refid="Base_Column_List" />
FROM users
WHERE id = #{id}
</select>
<insert id="insert" parameterType="com.huaxun.springboot.entity.User" >
INSERT INTO
users
(userName,passWord,user_sex)
VALUES
(#{userName}, #{passWord}, #{userSex})
</insert>
<update id="update" parameterType="com.huaxun.springboot.entity.User" >
UPDATE
users
SET
<if test="userName != null">userName = #{userName},</if>
<if test="passWord != null">passWord = #{passWord},</if>
nick_name = #{nickName}
WHERE
id = #{id}
</update>
<delete id="delete" parameterType="java.lang.Long" >
DELETE FROM
users
WHERE
id =#{id}
</delete>
</mapper>
6、在java代码目录里面新建mapper包，并创建UserMapper接口
public interface UserMapper {
List getAll();
User getOne(Long id);
void insert(User user);
void update(User user);
void delete(Long id);
}
7、在webapp目录下新建index.jsp文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
<form action="/user/save" method="post">
<table border="1">
<tr>
<td>姓名</td>
<td><input type="text" name="userName"/></td>
</tr>
<tr>
<td>密码</td>
<td><input type="text" name="passWord"/></td>
</tr>
<tr align="center">
<td colspan="2"><input type="submit" value="提交"/></td>
</tr>
</table>
</form>
</body>
</html>
8、在webapp目录下的WEB-INF目录下新建jsp文件夹，并新建success.jsp文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Title</title>
</head>
<body>
插入成功<br/>
${sessionScope.userName}<br/>
${requestScope.passWord}
</body>
</html>
9、运行启动SpringBoot的main方法，注意，需要加@MapperScan全局扫描，需和application.properties配置的mybatis.type-aliases-package一致
@SpringBootApplication
@MapperScan("com.huaxun.springboot.mapper")
public class SpringbootApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootApplication.class, args);
}
}
10、浏览器打开localhost:8080/index.jsp

11、填入数据，点击提交后成功跳转页面
