mybatisPlus代码生成
是使用Mybatis Plus代码生成器生成代码的例子:
首先,需要在pom.xml文件中添加Mybatis Plus的依赖:
```xml
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>mybatis-plus</artifactId>
<version>3.4.2</version>
</dependency>
```
然后,在application.yml文件中配置数据库连接信息:
```yaml
spring:
datasource:
url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8
username: root
password: root
driver-class-name: com.mysql.cj.jdbc.Driver
```
接下来,创建一个代码生成器类,例如:
```java
package com.example.demo.generator;
import com.baomidou.mybatisplus.annotation.DbType;import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import com.baomidou.mybatisplus.core.exceptions.MybatisPlusException;
import com.baomidou.mybatisplus.core.toolkit.StringUtils;
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 java.util.Scanner;
public class CodeGenerator {
public static void main(String[] args) {
// 代码生成器
AutoGenerator mpg = new AutoGenerator();
// 全局配置
GlobalConfig gc = new GlobalConfig();
String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
gc.setAuthor("yourname");
gc.setOpen(false);
gc.setFileOverride(false);
gc.setServiceName("%sService");
gc.setIdType(IdType.AUTO);
gc.setDateType(DateType.ONLY_DATE);
gc.setSwagger2(true);
mpg.setGlobalConfig(gc);
// 数据源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8");
dsc.setDriverName("com.mysql.cj.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("root");
dsc.setDbType(DbType.MYSQL);
mpg.setDataSource(dsc);
// 包配置
PackageConfig pc = new PackageConfig();
pc.setModuleName(scanner("模块名"));
pc.setParent("com.example.demo");
pc.setEntity("entity");
pc.setMapper("mapper");
pc.setService("service");
pc.setServiceImpl("service.impl");
pc.setController("controller");
mpg.setPackageInfo(pc);
// 策略配置
StrategyConfig strategy = new StrategyConfig();
strategy.setNaming(NamingStrategy.underline_to_camel);
strategy.setColumnNaming(NamingStrategy.underline_to_camel);
strategy.setEntityLombokModel(true);
strategy.setRestControllerStyle(true);
strategy.setControllerMappingHyphenStyle(true);
strategy.setInclude(scanner("表名,多个英文逗号分割").split(","));
strategy.setTablePrefix(pc.getModuleName() + "_");
mpg.setStrategy(strategy);
mpg.execute();
}
private static String scanner(String tip) {
Scanner scanner = new Scanner(System.in);
StringBuilder sb = new StringBuilder();
sb.append("请输入" + tip + ":");
System.out.println(sb.toString());
if (scanner.hasNext()) {
String ipt = scanner.next();
if (StringUtils.isNotBlank(ipt)) {
return ipt;
}
}
throw new MybatisPlusException("请输入正确的" + tip + "!");
}
}
```
在上面的代码中,我们可以看到Mybatis Plus代码生成器的主要配置,包括全局配置、数据源配置、包配置和策略配置。其中,我们需要根据实际情况修改数据库连接信息、模块名、表名等配置。
最后,运行CodeGenerator类即可生成代码。
