MyBatis-Plus Generator代码生成器

1.加入mybatis-plus相关依赖

<dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>3.5.1</version>
</dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-generator</artifactId><version>3.5.1</version>
</dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId>
</dependency>

2.加入mysql数据库连接的驱动

<dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId>
</dependency>

3.交互式生成

GlobalConfig config = GeneratorBuilder.globalConfigBuilder().author("******") // 作者.outputDir("F:\\java") // 生成路径.fileOverride()  // 文件覆盖.dateType(DateType.TIME_PACK).commentDate("yyyy-MM-dd").enableSwagger().build();//生成基本的SQL片段//mysql数据源配置
DataSourceConfig dsc =  new DataSourceConfig.Builder("jdbc:mysql://***.***.***.***:3306/database?useUnicode=true&characterEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai&allowPublicKeyRetrieval=true&allowMultiQueries=true", "***", "***").dbQuery(new MySqlQuery()).build();// 策略配置
StrategyConfig strategy = GeneratorBuilder.strategyConfigBuilder().addInclude("t_user")    //表名.addTablePrefix("t_")    //表前缀//Entity配置.entityBuilder().naming(NamingStrategy.underline_to_camel).columnNaming(NamingStrategy.underline_to_camel).versionColumnName("version").logicDeleteColumnName("isDelete").enableLombok()//开启 lombok 模型，默认值:false.enableChainModel()//开启链式模型，默认值:false.enableRemoveIsPrefix()//开启 Boolean 类型字段移除 is 前缀，默认值:false.enableTableFieldAnnotation()//开启生成实体时生成字段注解，默认值:false.enableActiveRecord()//开启 ActiveRecord 模型，默认值:false.idType(IdType.AUTO)//全局主键类型//.superClass(BaseEntity.class).addSuperEntityColumns("create_by","create_time","update_by","update_time","remark")//Controller配置.controllerBuilder().enableHyphenStyle().enableRestStyle().formatFileName("%sController")//.superClass(BaseController.class)//Service配置.serviceBuilder().formatServiceFileName("%sService").formatServiceImplFileName("%sServiceImpl")//Mapper配置.mapperBuilder()//mapper 策略配置.enableBaseResultMap()//启用 BaseResultMap 生成，默认值:false.enableBaseColumnList()//启用 BaseColumnList，默认值:false.formatMapperFileName("%sMapper")//转换 mapper 接口文件名称后缀，mapper目录下的，例如：UserLoginMapper（有@Mapper）.formatXmlFileName("%sMapper").build();String basePackage = "com.sf.uimp.report";   //包名// 包名策略配置
PackageConfig pkConfig = GeneratorBuilder.packageConfigBuilder().parent(basePackage).mapper("dao").service("service").controller("controller").entity("model").xml("mapper")//.pathInfo(Collections.singletonMap(OutputFile.mapperXml, "src/main/resources/mapper")).build();TemplateConfig templateConfig = GeneratorBuilder.templateConfigBuilder().build();// 代码生成器
AutoGenerator mpg = new AutoGenerator(dsc).global(config).strategy(strategy).template(templateConfig).packageInfo(pkConfig);
mpg.execute();

4.连接clickhouse自动生成代码

<dependency><groupId>ru.yandex.clickhouse</groupId><artifactId>clickhouse-jdbc</artifactId><version>0.3.2</version>
</dependency>

//clickhouse数据源配置
DataSourceConfig dsc =  new DataSourceConfig.Builder("jdbc:clickhouse://***.***.***.***:8123/database", "***", "***").dbQuery(new ClickHouseQuery()).typeConvert(new ClickHouseTypeConvert(){@Overridepublic IColumnType processTypeConvert(GlobalConfig globalConfig, String fieldType) {if(fieldType.toLowerCase().contains("int")){return DbColumnType.LONG;} else {return super.processTypeConvert(globalConfig, fieldType);}}}).build();
