SpringBoot整合mybatis

1. 创建springboot项目，maven添加依赖

           
           
               org.mybatis.spring.boot
               mybatis-spring-boot-starter
               1.3.2
           
   
           
           
               mysql
               mysql-connector-java
           

    

2. 在配置文件application.yml中添加配置

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/ry?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
# MyBatis
mybatis:
  # 搜索指定包别名
  typeAliasesPackage: com.example.demo.entity
#  # 配置mapper的扫描，找到所有的mapper.xml映射文件
#  mapperLocations: classpath*:mapper/**/*Mapper.xml
  # 加载全局的配置文件
  configLocation: classpath:mapper/mybatis-config.xml

 

3. 在启动类中加@MapperScan注解

@SpringBootApplication
@MapperScan("com.example.demo.mapper")
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

4.mybatis-config.xml配置文件

 5.logback-spring.xml配置mybaits打印sql日志
