1、效能分析外掛，加入mybatis-puls 的元件

   //效能分析外掛
    @Bean
    @Profile({"dev","test"})
    public PerformanceInterceptor performanceInterceptor(){
        PerformanceInterceptor performanceInterceptor = new PerformanceInterceptor();
        performanceInterceptor.setMaxTime(2000);
        performanceInterceptor.setFormat(
 
true);
        return performanceInterceptor;
    }

3、Wapper條件構造器

@RunWith(SpringRunner.class)
@SpringBootTest
public class WapperTest {

    @Autowired
    private UserMapper userMapper;

    @Test
    public void testSelect() {
        Page<User> page = new Page<>(1,8);
        QueryWrapper
 
<User> wappper = new QueryWrapper<>();
        wappper.eq("name","edwin");
        IPage<User> userIPage = userMapper.selectPage(page, wappper);
        List<User> records = userIPage.getRecords();
        records.forEach(System.out::println);
    }
}

4、Mybatis-plus 的程式碼生成器

public
 
 static void main(String[] args) {
        // 需要構建一個 程式碼自動生成器 物件
        AutoGenerator mpg = new AutoGenerator();
        // 1、全域性配置
        GlobalConfig gc = new GlobalConfig();
        String projectPath = System.getProperty("user.dir").concat("/mybatis-plus");
        gc.setOutputDir(projectPath+"/src/main/java");
        gc.setAuthor("危存盛");
        gc.setOpen(false);
        gc.setFileOverride(false); // 是否覆蓋
        gc.setServiceName("%sService"); // 去Service的I字首
        gc.setIdType(IdType.ID_WORKER);
        gc.setDateType(DateType.ONLY_DATE);
        gc.setSwagger2(true);
        mpg.setGlobalConfig(gc);

        //2、設定資料來源
        DataSourceConfig dsc = new DataSourceConfig();
        dsc.setUrl("jdbc:mysql://8.129.215.115:3306/mybatis_plus? useSSL=false&useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8");
        dsc.setDriverName("com.mysql.cj.jdbc.Driver");
        dsc.setUsername("root");
        dsc.setPassword("root");
        dsc.setDbType(DbType.MYSQL);
        mpg.setDataSource(dsc);

        //3、包的配置
        PackageConfig pc = new PackageConfig();
        //pc.setModuleName("system");//如果有模組名就配置這個
        pc.setParent("com.wei.shun.mybatis.plus");
        pc.setEntity("entity");
        pc.setMapper("mapper");
        pc.setService("service");
        pc.setController("controller");
        mpg.setPackageInfo(pc);

        //4、策略配置
        StrategyConfig strategy = new StrategyConfig();
        strategy.setInclude("my_user"); // 設定要對映的表名
        strategy.setNaming(NamingStrategy.underline_to_camel);
        strategy.setColumnNaming(NamingStrategy.underline_to_camel);
        strategy.setEntityLombokModel(true); // 自動lombok；
        strategy.setLogicDeleteFieldName("deleted");

        // 自動填充配置
        TableFill gmtCreate = new TableFill("create_time", FieldFill.INSERT);
        TableFill gmtModified = new TableFill("update_time", FieldFill.INSERT_UPDATE);
        ArrayList<TableFill> tableFills = new ArrayList<>();
        tableFills.add(gmtCreate);
        tableFills.add(gmtModified);
        strategy.setTableFillList(tableFills);
        // 樂觀鎖
        strategy.setVersionFieldName("version");
        strategy.setRestControllerStyle(true);
        strategy.setControllerMappingHyphenStyle(true); // localhost:8080/hello_id_2
        mpg.setStrategy(strategy);
        mpg.execute(); //執行
    }
