mybatis-plus自动生成模板

1.依赖pom

2.生成代码

   String url = "jdbc:mysql://xx:3306/xx?serverTimezone=GMT%2B8&zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8&useSSL=false";

FastAutoGenerator.create(url, "username", "passsword")
	.globalConfig(builder -> {
	    builder.author("fuhao") // 设置作者
	            .enableSwagger() // 开启 swagger 模式
	            .fileOverride() // 覆盖已生成文件
	            .outputDir("D://workspace/xx/src/main/java"); // 指定输出目录
	})
	.dataSourceConfig(builder -> builder.typeConvertHandler((globalConfig, typeRegistry, metaInfo) -> {
	    int typeCode = metaInfo.getJdbcType().TYPE_CODE;
	    if (typeCode == Types.SMALLINT) {
	        // 自定义类型转换
	        return DbColumnType.INTEGER;
	    }
	    return typeRegistry.getColumnType(metaInfo);
	
	}))
	.packageConfig(builder -> {
	    builder.parent("com.xx.xx")
	            .entity("entity")
	            .service("service")
	            .serviceImpl("service.impl")
	            .mapper("mapper")
	            .xml("mapper.xml")
	            .controller("controller")
	            .pathInfo(Collections.singletonMap(OutputFile.xml, "D://workspace/xx/src/main/resources/mapper")) //mapper.xml生成路径设置
	            ;
	})
	.strategyConfig(builder -> {
	    builder
	            .addInclude("xx") // 指定要生成的表，不定项参数，可指定多个
	            .likeTable(new LikeTable("xx_"))//模糊匹配要生成的表
	            .addTablePrefix("xx_")  //生成类、mapper时，忽略、删除的前缀
	            .addFieldPrefix("xx") //生成类字段时，忽略、删除的前缀
	            .addFieldSuffix("")  //生成类字段时，忽略、删除的后缀
	    ; // 设置过滤表前缀
	})
	.templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
	.execute();
