[Java知识库]springboot集成mybatis-plus

1.导入依赖

        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.3.1</version>
        </dependency>

2.编写配置文件

spring:
  application:
    name: keep-learning-business
  datasource:
    url: jdbc:mysql://localhost:3306/keep_learning?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
mybatis-plus:
  mapper-locations: classpath*:/mapper/**/*.xml
  global-config:
    db-config:
      id-type: auto

3.在启动类添加注解扫描
@MapperScan(“com.keep.learning.business.mapper”)

4.编写service与mapper

public interface StudentService extends IService<StudentEntity> {
}

@Service
public class StudentServiceImpl extends ServiceImpl<StudentMapper, StudentEntity> implements StudentService {
}

public interface StudentMapper extends BaseMapper<StudentEntity> {
}

<?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.keep.learning.business.mapper.StudentMapper">

</mapper>
