mybatis-plus-generator實現代碼自動生成器

第一步：引入依賴

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.5.1</version>
</dependency>
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.5.3</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <scope>runtime</scope>
</dependency>

第二步：applicatio.yml配置

mybatis-plus:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    #開啟sql日志
    map-underscore-to-camel-case: true
    # 該配置就是將帶有下劃線的表字段映射為駝峰格式的實體類屬性
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/data0917?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=UTF-8
    username: root
    password: root

第三步：創建測試類并執行， 然后在設置的目錄下自動 生成 xml,service,mapper,controller文件

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.Collections;

@SpringBootTest
public class MyBatisPlusGenerator {
    @Test
    public  void fastAutoGeneratorTest(){
        String url="jdbc:mysql://localhost:3306/data0917?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=UTF-8";
        FastAutoGenerator.create(url, "root", "root")
                .globalConfig(builder -> {
                    builder.author("carl") // 設置作者
                           // .enableSwagger() // 開啟 swagger 模式
                            .outputDir("F://java//javaProject//batis-genteraor//src//main//java//"); // 指定輸出目錄
                })
                .packageConfig(builder -> {
                    builder.parent("com.zhuangzi") // 設置父包名
                            .moduleName("batisgenteraor") // 設置父包模塊名
                            .pathInfo(Collections.singletonMap(OutputFile.xml, "F://java//javaProject//batis-genteraor//src//main//resources//mapper//")); // 設置mapperXml生成路徑
                })
                .strategyConfig(builder -> {
                    builder.addInclude("users"); // 設置需要生成的表名
                    // .addTablePrefix("t_", "c_"); // 設置過濾表前綴
                })
                .templateEngine(new FreemarkerTemplateEngine())
                // 使用Freemarker引擎模板，默認的是Velocity引擎模板
                .execute();

    }
}
