mybites 生成代码配文件 generatorConfig.xml 路径(插件指定的位置)

    </context>
</generatorConfiguration>

运行插件

我是点击idea maven按钮的

添加配置 application.yml

server:
  port: 8080
spring:
  datasource:
    url: jdbc:mysql://192.168.1.12/jpa?characterEncoding=utf-8
    username: root
    password: pass
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true
    #不加这句则默认为myisam引擎
    database-platform: org.hibernate.dialect.MySQL5InnoDBDialect

实战查询

单元测试,好习惯

@Slf4j
public class Test01 extends BootGameApplicationTests {
    @Resource
    private UsersGameBetDetailService usersGameBetDetailService;

    @Test
    public void test(){
        UsersGameBetDetailExample usersGameBetDetailExample = new UsersGameBetDetailExample();
        PageParameter pageParameter = new PageParameter();
        pageParameter.setPageNum(0);
        pageParameter.setPageSize(10);
        String date = "2018-09-20 18:51:55";
        Instant instant = Instant.ofEpochMilli(1537468800000L);
        Date from = Date.from(instant);
        // Mybatis查询方法
        usersGameBetDetailExample.createCriteria().andBettimeLessThan(from);
        PageInfo<UsersGameBetDetail> usersGameBetDetailPageInfo = usersGameBetDetailService.pageQuery(usersGameBetDetailExample, pageParameter);
        //UsersGameBetDetail usersGameBetDetail = usersGameBetDetailMapper.selectByPrimaryKey(1925881);
        log.info("");
    }
}
