MyBatis-Plus之程式碼生成器

一、引入pom依賴

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

  <artifactId>mp01</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  
  <dependencies>
  		<!-- mp依賴
  			 mybatisPlus 會自動的維護Mybatis 以及MyBatis-spring相關的依賴
  		 -->
		<dependency>

</project>

二、配置測試

	public void  testGenerator() {
		//1. 全域性配置
		GlobalConfig config = new GlobalConfig();
		config.setActiveRecord(true) // 是否支援AR模式
			  .setAuthor("Tanghoa") // 作者
			  .setOutputDir("XXXX")
			  //XXX:為程式碼路徑地址：直接複製過來即可  D:\\workspace
			  .setFileOverride(true)  // 檔案覆蓋
			  .setIdType(IdType.AUTO) // 主鍵策略
			  .setServiceName("%sService")  // 設定生成的service介面的名字的首字母是否為I
			  					   // IEmployeeService
 			  .setBaseResultMap(true)
 			  .setBaseColumnList(true);
		
		//2. 資料來源配置
		DataSourceConfig  dsConfig  = new DataSourceConfig();
		dsConfig.setDbType(DbType.MYSQL)  // 設定資料庫型別
				.setDriverName("com.mysql.jdbc.Driver")
				.setUrl("jdbc:mysql://localhost:3306/mp")
				.setUsername("root")
				.setPassword("123456");
		 
		//3. 策略配置
		StrategyConfig stConfig = new StrategyConfig();
		stConfig.setCapitalMode(true) //全域性大寫命名
				.setDbColumnUnderline(true)  // 指定表名 欄位名是否使用下劃線
				.setNaming(NamingStrategy.underline_to_camel) // 資料庫表對映到實體的命名策略
				.setTablePrefix("tbl_")
				.setInclude("tbl_user");  // 生成的表
		
		//4. 包名策略配置 
		PackageConfig pkConfig = new PackageConfig();
		pkConfig.setParent("com.XXX.xx")
				.setMapper("mapper")
				.setService("service")
				.setController("controller")
				.setEntity("beans")
				.setXml("mapper");
		
		//5. 整合配置
		AutoGenerator  ag = new AutoGenerator();
		
		ag.setGlobalConfig(config)
		  .setDataSource(dsConfig)
		  .setStrategy(stConfig)
		  .setPackageInfo(pkConfig);
		
		//6. 執行
		ag.execute();
	}
