mysql注意点:
1.有关编码 create table user( id int primary key auto_increment, `name` varchar(255), `password` varchar(255) )ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8; 需要加上引擎的注释和默认数据库编码
application.properties的默认写法
#数据源 spring.datasource.url=jdbc:mysql://120.78.206.78:3306/testMybatisClient?useUnicode=true&characterEncoding=utf8 spring.datasource.username=root spring.datasource.password=Root123.. #用来实例化mapper接口 mybatis.type-aliases-package=com.littlepage.mapper #对应的sql映射 mybatis.mapper-locations=classpath:mybatis/mapper/*.xml #首页 server.servlet.context-path=/ #日志级别 logging.level.com.littlepage.mybatis.mapper=debug #连接池 spring.datasource.hikari.minimum-idle=3 spring.datasource.hikari.maximum-pool-size=10 spring.datasource.hikari.max-lifetime =30000 spring.datasource.hikari.connection-test-query=SELECT 1
MapperScan
@SpringBootApplication @MapperScan("com.littlepage.mapper") public class MybatisApplication { public static void main(String[] args) { SpringApplication.run(MybatisApplication.class, args); } } 启动类进行mapper的扫描
