MyBatisPlus 自动生成

根据数据表自动生成实体类、Mapper、Service、
ServiceImpl、Controller

1、pom.xml 导⼊ MyBatis Plus Generator

<dependency>
 <groupId>com.baomidou</groupId>
 <artifactId>mybatis-plusgenerator</artifactId>
 <version>3.3.1.tmp</version>
</dependency> <dependency>
 <groupId>org.apache.velocity</groupId>
 <artifactId>velocity</artifactId>
 <version>1.7</version>
</dependency>

Velocity（默认）、Freemarker、Beetl

2、启动类

rator;

ules.NamingStrategy;
public class Main {
 public static void main(String[] args) {
 //创建generator对象
 AutoGenerator autoGenerator = new
AutoGenerator();
 //数据源
 DataSourceConfig dataSourceConfig =
new DataSourceConfig();
 
dataSourceConfig.setDbType(DbType.MYSQL);
 
dataSourceConfig.setUrl("jdbc:mysql://ip:3
306/db?
useUnicode=true&characterEncoding=UTF-8");
 
dataSourceConfig.setUsername("root");
 
dataSourceConfig.setPassword("root");
 
dataSourceConfig.setDriverName("com.mysql.
cj.jdbc.Driver");
 
autoGenerator.setDataSource(dataSourceConf
ig);
 //全局配置
 GlobalConfig globalConfig = new
GlobalConfig();
 
globalConfig.setOutputDir(System.getProper
ty("user.dir")+"/src/main/java");
 globalConfig.setOpen(false);
 
globalConfig.setAuthor("southwind");
 
globalConfig.setServiceName("%sService");
 
autoGenerator.setGlobalConfig(globalConfig
);
 //包信息
 PackageConfig packageConfig = new
PackageConfig();
 
packageConfig.setParent("com.southwind.myb
atisplus");
 
packageConfig.setModuleName("generator");
 
packageConfig.setController("controller");
 
packageConfig.setService("service");
 
packageConfig.setServiceImpl("service.impl
");
 packageConfig.setMapper("mapper");
 packageConfig.setEntity("entity");
 
autoGenerator.setPackageInfo(packageConfig
);
 //配置策略
 StrategyConfig strategyConfig = new
StrategyConfig();
 
strategyConfig.setEntityLombokModel(true);
 
strategyConfig.setNaming(NamingStrategy.un
derline_to_camel);
 
strategyConfig.setColumnNaming(NamingStrat
egy.underline_to_camel);
 
autoGenerator.setStrategy(strategyConfig);
 autoGenerator.execute();
 }
