    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();
    
        }
    }
