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

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

/** * @Description: * @Author: rongyu * @CreateDate: 2018/10/10$ 14:37$ * @Remark: */ @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(""); } }
