SpringBoot之配置Mybatis

1、在pom.xml配置文件添加以下依赖

 <!--mybatis依赖-->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>2.3.0</version>
        </dependency>

2、在application.yml中添加以下配置

map-underscore-to-camel-case: true #将数据库表有下划线字段自动映射成小驼峰

type-aliases-package: com.example.springboot_mybatis.pojo #需要命别名的实体类所在的包全名

#配置mybatis
mybatis:
  configuration:
    map-underscore-to-camel-case: true 
  mapper-locations: classpath:/mapper/*.xml  #resources/mapper/xxx.xml
  type-aliases-package: com.example.springboot_mybatis.pojo
#以debug模式在后台打印sql语句
logging:
  level:
    com.example.springboot_mybatis: debug
