1、创建表
DROP TABLE IF EXISTS `user_info`;
CREATE TABLE `user_info` (
`id` int(64) NOT NULL AUTO_INCREMENT,
`name` varchar(32) DEFAULT NULL,
`password` varchar(64) DEFAULT NULL,
`salt` varchar(64) DEFAULT NULL,
`state` varchar(8) DEFAULT NULL,
`username` varchar(32) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;
2、POM.xml
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

3、在resources下创建 generator文件夹，并创建generator.xml文件
4、generator.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!-- 数据库驱动:选择你的本地硬盘上面的数据库驱动包-->
<classPathEntry location="D:\Maven\repository\repo\mysql\mysql-connector-java\5.1.45\mysql-connector-java-5.1.45.jar"/>
<!-- 表设计时有联合主键时， 不需要单独主键实体类时 把defaultModelType设置为flat -->
<context id="DB2Tables" targetRuntime="MyBatis3" defaultModelType="flat">
<!-- JavaBean 实现 序列化 接口 -->
<plugin type="org.mybatis.generator.plugins.SerializablePlugin" />
<!-- 生成toString -->
<plugin type="org.mybatis.generator.plugins.ToStringPlugin" />
<!-- optional，旨在创建class时，对注释进行控制 -->
<commentGenerator>
<property name="suppressDate" value="true"/>
<!-- <property name="suppressAllComments" value="true"/>-->
</commentGenerator>
<!--数据库链接URL，用户名、密码 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://127.0.0.1:3306/library"
userId="root"
password="root">
</jdbcConnection>
<!-- 类型转换 -->
<javaTypeResolver >
<!-- 是否使用bigDecimal,
false: 把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer(默认)
true: 把JDBC DECIMAL 和 NUMERIC 类型解析为java.math.BigDecimal
-->
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 生成模型的包名和位置-->

<property name="trimStrings" value="true" />
</javaModelGenerator>
<!-- 生成映射文件的包名和位置-->
<sqlMapGenerator targetPackage="mappers" targetProject="src/main/resources">

<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
<table tableName="user_info"></table>
</context>
</generatorConfiguration>
5、Run->Edit Configurations->+号Maven 选择Working directory,项目所在路径，在Command line输入:mybatis-generator:generate -e
或者 右键 run mybatis-generator 生成文件
6、application.properties
#数据源配置
spring.datasource.driver-class-name = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/library?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai
spring.datasource.username = root
spring.datasource.password = root
## Mybatis 配置
# 配置为 com.example.restfuldemo.domain 指向实体类包路径。
mybatis.typeAliasesPackage=com.example.restfuldemo.domain
# 配置为 classpath 路径下 mapper 包下，* 代表会扫描所有 xml 文件。
mybatis.mapperLocations=classpath:/mappers/*.xml
7、UserInfoService与Impl
package com.example.restfuldemo.service;
import com.example.restfuldemo.domain.UserInfo;
import java.util.List;
public interface UserInfoService {
/**
* 新增用户
* @param userInfo
* @return
*/
int addUser(UserInfo userInfo);
/**
* 修改用户
* @param userInfo
* @return
*/
int updateUser(UserInfo userInfo);
/**
* 删除用户
* @param id
* @return
*/
int delUser(int id);
/**
* 查询所有用户
* @return
*/
List<UserInfo> findAll();
}
package com.example.restfuldemo.service;
import com.example.restfuldemo.dao.UserInfoMapper;
import com.example.restfuldemo.domain.UserInfo;
import com.example.restfuldemo.domain.UserInfoExample;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class UserInfoServiceImpl implements UserInfoService{
@Autowired
UserInfoMapper userInfoMapper;
@Override
public int addUser(UserInfo userInfo) {
int result = 0;
result = userInfoMapper.insert(userInfo);
return result;
}
@Override
public int updateUser(UserInfo userInfo) {
int result = 0;
result = userInfoMapper.updateByPrimaryKey(userInfo);
return result;
}
@Override
public int delUser(int id) {
int result = 0;
result = userInfoMapper.deleteByPrimaryKey(id);
return result;
}
@Override
public List<UserInfo> findAll() {
UserInfoExample example = new UserInfoExample();
//有查询条件框时这样写
// UserInfoExample.Criteria criteria = example.createCriteria();
// criteria.andUsernameLike("%"+username+"%");
List<UserInfo> userInfos = userInfoMapper.selectByExample(example);
return userInfos;
}
}
8、controller
package com.example.restfuldemo.controller;
import com.example.restfuldemo.domain.UserInfo;
import com.example.restfuldemo.service.UserInfoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
@RestController
@RequestMapping("/api")
public class UserInfoController {
@Autowired
UserInfoService userInfoService;
@PostMapping
@GetMapping("/POST/users")
public int addUser(UserInfo userInfo){
return userInfoService.addUser(userInfo);
}
@PutMapping
@GetMapping("/PUT/users")
public int updateUser(UserInfo userInfo){
return userInfoService.updateUser(userInfo);
}
@DeleteMapping
@GetMapping("/DELETE/users")
public int delUser(int id){
return userInfoService.delUser(id);
}
@GetMapping("/GET/users/userAll")
public List<UserInfo> findAll(){
return userInfoService.findAll();
}
}
