## mybatisplus自动生成代码 ##

入口类：

package com.mbpnj.codegenerator;
    
    import com.baomidou.mybatisplus.annotation.DbType;
    import com.baomidou.mybatisplus.annotation.IdType;
    import com.baomidou.mybatisplus.generator.AutoGenerator;
    import com.baomidou.mybatisplus.generator.config.DataSourceConfig;
    import com.baomidou.mybatisplus.generator.config.GlobalConfig;
    import com.baomidou.mybatisplus.generator.config.PackageConfig;
    import com.baomidou.mybatisplus.generator.config.StrategyConfig;
    import com.baomidou.mybatisplus.generator.config.rules.DateType;
    import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
    import org.junit.jupiter.api.Test;
    
    public class CodeGenerator {
        
        @Test
        public void test() {
        
            // 1、创建代码生成器
            AutoGenerator mpg = new AutoGenerator();
    
            // 2、全局配置
            GlobalConfig gc = new GlobalConfig();
            String projectPath = System.getProperty("user.dir");
            gc.setOutputDir(projectPath + "/src/main/java");
            gc.setAuthor("作者");
            gc.setOpen(false); //生成后是否打开资源管理器
            gc.setFileOverride(false); //重新生成时文件是否覆盖
            gc.setServiceName("%sService"); //去掉Service接口的首字母I
            gc.setIdType(IdType.AUTO); //主键策略
            gc.setDateType(DateType.ONLY_DATE);//定义生成的实体类中日期类型
            gc.setSwagger2(false);//开启Swagger2模式
    
            mpg.setGlobalConfig(gc);
    
            // 3、数据源配置
            DataSourceConfig dsc = new DataSourceConfig();
            dsc.setUrl("jdbc:mysql://ip地址:端口/数据库名");
            dsc.setDriverName("com.mysql.jdbc.Driver");
            dsc.setUsername("账户");
            dsc.setPassword("密码");
            dsc.setDbType(DbType.MYSQL);
            mpg.setDataSource(dsc);
    
            // 4、包配置
            PackageConfig pc = new PackageConfig();
            pc.setModuleName(null); //模块名
            pc.setParent("包的全路径");
            pc.setEntity("entity");
            pc.setService("service");
            pc.setMapper("repository");
            mpg.setPackageInfo(pc);
    
            // 5、策略配置
            StrategyConfig strategy = new StrategyConfig();
            strategy.setInclude("要生成的数据库表");//对那一张表生成代码
            strategy.setNaming(NamingStrategy.underline_to_camel);//数据库表映射到实体的命名策略
            strategy.setTablePrefix(pc.getModuleName() + "_"); //生成实体时去掉表前缀
            strategy.entityTableFieldAnnotationEnable(true);//实体属性上添加表字段映射
            strategy.setColumnNaming(NamingStrategy.underline_to_camel);//数据库表字段映射到实体的命名策略
    //        strategy.setEntityLombokModel(true); // lombok 模型 @Accessors(chain = true) setter链式操作
    
            strategy.setRestControllerStyle(true); //restful api风格控制器
            strategy.setControllerMappingHyphenStyle(true); //url中驼峰转连字符
    
            mpg.setStrategy(strategy);
    
            // 6、执行
            mpg.execute();
        }
    }

我们在IDE里面直接创建一个maven工程，把依赖和类直接建成，就可以直接使用的，开箱即用
