1.引入pom依赖
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus-generator</artifactId>
<version>3.3.1.tmp</version>
</dependency>
<dependency>
<groupId>org.apache.velocity</groupId>
<artifactId>velocity-engine-core</artifactId>
<version>2.2</version>
</dependency>
2.Code
package com.wang.mybatisplus;
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.NamingStrategy;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class MybatisPlusGeneratorApplicationTests {
@Test
void codeGenerator () {
// 代码生成器
AutoGenerator mpg = new AutoGenerator();
// 1.全局配置
GlobalConfig gc = new GlobalConfig();
gc.setActiveRecord(true);//支持AR模式
String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
gc.setFileOverride(true);//文件覆盖
gc.setIdType(IdType.AUTO);//主键自增
gc.setServiceName("%sService");//设置接口名称是否有I
gc.setAuthor("王一宁");
gc.setBaseResultMap(true);//xml映射
gc.setBaseColumnList(true);//sql片段
mpg.setGlobalConfig(gc);
// 2.数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://localhost:3306/mp?serverTimeznotallow=UTC&useUnicode=true&useSSL=false&characterEncoding=utf8");
dsc.setDbType(DbType.MYSQL);
dsc.setDriverName("com.mysql.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("123456");
mpg.setDataSource(dsc);
// 3.策略配置
StrategyConfig strategyConfig = new StrategyConfig();
strategyConfig.setCapitalMode(true);//全局大小写命名
strategyConfig.setNaming(NamingStrategy.underline_to_camel);
strategyConfig.setColumnNaming(NamingStrategy.underline_to_camel);
strategyConfig.setTablePrefix("tbl_");
strategyConfig.setEntityLombokModel(true);//使用lombok
strategyConfig.setInclude("tbl_user");//生成使用的表
// 4.包配置
PackageConfig pc = new PackageConfig();
pc.setParent("com.wang.mybatisplus");
pc.setMapper("mapper");
pc.setService("service");
pc.setController("controller");
pc.setEntity("domain");
pc.setXml("mapper");
mpg.setPackageInfo(pc);
// 5.执行
mpg.execute();
}
