使用IDEA构建Spring boot2.0+版本+MyBatis（properties文件配置）

最近项目从SSM转SpringBoot,但是不是用MyBatis而是用Spring JDBC
这篇博文也算记录我SpringBoot的搭建

1、Intellij idea菜单栏File->new->project
选择左侧栏中spring initializr，右侧选择jdk版本，以及默认的Service URL，点击next。

2、然后填写项目的Group、Artifact等信息，然后点击next

3、我这边是选择了Web->Web和Core->Aspects ,然后点击next

4、填写Project name 等信息，然后点击Finish。

maven web项目就这样创建好了

配置pom.xml:

<!-- Springboot jar-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-aop</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

<!-- mybatis jar -->
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.1</version>
</dependency>

<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>

</dependency>

</dependencies>

application.properties

spring.datasource.url:jdbc:mysql://数据库地址:3306/test?useUnicode=true&characterEncoding=utf-8&noDatetimeStringSync=true&serverTimezone=Hongkong
spring.datasource.driverClassName:com.mysql.jdbc.Driver
spring.datasource.username:root
spring.datasource.password:root
server.port=8081

mybatis.mapper-locations:classpath:mapper/*.xml
#配置模型路径
mybatis.type-aliases-package=com.

然后把项目的entity,mapper,service,controller创建出来，整体架构如图:

entity里面User：

public class User {

private int id;

private String userName;

public int getId() {
return id;
}

public User setId(int id) {
this.id = id;
return this;
}

public String getUserName() {
return userName;
}

public User setUserName(String userName) {
this.userName = userName;
return this;
}
}

mapper里面的UserMapper：

@Mapper
public interface UserMapper {

void add(User user);

List<User> listAll(User user);
}

service里面的UserService：

@Service
public class UserService {

@Autowired
private UserMapper userMapper;

public List<User> listAll(User user) {
return userMapper.listAll(user);
}

public void add(User user){
userMapper.add(user);
}
}

controller里面的UserController:

@Controller
@RequestMapping(value = "/user")
public class UserController {

@Autowired
private UserService userService;

@RequestMapping(value = "index")
@ResponseBody
public List<User> index(User user){

return userService.listAll(user);
}
}

resoures->mappe文件里面的UserMapper.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://www.mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.lwj.springboot.mapper.UserMapper">

<resultMap id="UserResultMap" type="com.lwj.springboot.entity.User">
<id column="id" property="id"/>
<result column="user_name" property="userName"/>
</resultMap>

<insert id="add" parameterType="com.lwj.springboot.entity.User">
insert into user(user_name)
values (#{userName})
</insert>

<select id="listAll" parameterType="com.lwj.springboot.entity.User" resultMap="UserResultMap">
select * from user
</select>
</mapper>

SpringBoot整合Mybatis主要是在prop文件配置：

最后运行结果:

第一次写技术博文不足之处还请大家多多指正！这也算是我2018年的工作总结吧！
