1.先贴出整个项目目录
1.pom中加入mybatis的依赖
<!-- spring-boot整合mybatis --> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.1.1</version> </dependency> <!-- mysql驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.6</version> </dependency>
2.按项目目录添加文件
application.properties
server.port=8080
logging.level.org.springframework=DEBUG
#springboot mybatis
#jiazai mybatis peizhiwenjian
mybatis.mapper-locations = classpath:mapper/*.xml
mybatis.config-location = classpath:mapper/config/sqlMapConfig.xml
mybatis.type-aliases-package = com.hhf.springboot.demo01.bean
#shujuyuan
spring.datasource.driver-class-name= com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/youxiake?useUnicode=true&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = 123456
tip:注意端口包名

UserMapper.class
@Mapper public interface UserMapper { public List<User> findAll(); }
