### mybatisplus分頁外掛MybatisPlusConfig：
```java
package com.example.conf;
import com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
/**
* 配置分頁外掛
*
*/
@Configuration
public class MybatisPlusConfig {
/**
* 分頁外掛
*/
@Bean
public PaginationInterceptor paginationInterceptor() {
return new PaginationInterceptor();
}
}
```
### mybatisplus自動生成程式碼GeneratorCodeConfig.java：
```java
package com.example.conf;
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.*;
import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import java.util.Scanner;
/**
* 自動生成mybatisplus的相關程式碼
*/
public class GeneratorCodeConfig {
public static String scanner(String tip) {
Scanner scanner = new Scanner(System.in);
StringBuilder help = new StringBuilder();
help.append("請輸入" + tip + "：");
System.out.println(help.toString());
if (scanner.hasNext()) {
String ipt = scanner.next();
if (StringUtils.isNotEmpty(ipt)) {
return ipt;
}
}
throw new MybatisPlusException("請輸入正確的" + tip + "！");
}
public static void main(String[] args) {
// 程式碼生成器
AutoGenerator mpg = new AutoGenerator();
// 全域性配置
GlobalConfig gc = new GlobalConfig();
String projectPath = System.getProperty("user.dir");
gc.setOutputDir(projectPath + "/src/main/java");
gc.setAuthor("astupidcoder");
gc.setOpen(false);
//實體屬性 Swagger2 註解
gc.setSwagger2(false);
mpg.setGlobalConfig(gc);
// 資料來源配置
DataSourceConfig dsc = new DataSourceConfig();
dsc.setUrl("jdbc:mysql://127.0.0.1:3306/demo?serverTimezone=UTC&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true");
dsc.setDriverName("com.mysql.cj.jdbc.Driver");
dsc.setUsername("root");
dsc.setPassword("lyja");
mpg.setDataSource(dsc);
// 包配置
PackageConfig pc = new PackageConfig();
// pc.setModuleName(scanner("模組名"));
pc.setParent("com.example");
pc.setEntity("model.auto");
pc.setMapper("mapper.auto");
pc.setService("service");
pc.setServiceImpl("service.impl");
mpg.setPackageInfo(pc);
// 自定義配置
// InjectionConfig cfg = new InjectionConfig() {
// @Override
// public void initMap() {
// // to do nothing
// }
// };
// 如果模板引擎是 freemarker
// String templatePath = "/templates/mapper.xml.ftl";
// 如果模板引擎是 velocity
// String templatePath = "/templates/mapper.xml.vm";
// 自定義輸出配置
//
