mybatis-plus 代码生成器,直接复制可用_mybatis-plus代码怎么拷贝-优快云博客

引入依赖包，要保证你使用的是mybatis-plus而不是mybatis

<!-- 代码生成器 -->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.5.3</version>
</dependency>
<!--模板引擎有Velocity-->
<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity-engine-core</artifactId>
    <version>2.3</version>
</dependency>

实现代码，可在test包下创建test.java，要先在src/main/resources 下创建 mapper 包

package com.hzs.mall;

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.config.rules.DateType;

import java.util.Arrays;
import java.util.Collections;
import java.util.List;
import java.util.Scanner;

public class test {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.println("=================数据库配置==================");
        System.out.println("请输入 URL");
        String url = scan.next();
        System.out.println("请输入 username");
        String username = scan.next();
        System.out.println("请输入 password");
        String password = scan.next();

        FastAutoGenerator.create(url, username, password)
                // 全局配置
                .globalConfig((scanner, builder) -> builder.author(scanner.apply("==================全局配置===================\n请输入作者名称？"))
                        .outputDir(System.getProperty("user.dir") + "/src/main/java")
                        .commentDate("yyyy-MM-dd hh:mm:ss")
                        .dateType(DateType.TIME_PACK)
                        .disableOpenDir()
                )
                // 包配置
                .packageConfig((scanner, builder) -> builder.parent(scanner.apply("==================包配置====================\n请输入包名？"))
                        .moduleName(scanner.apply("请输入父包模块名？"))
                        .entity("entity")
                        .service("service")
                        .serviceImpl("service.impl")
                        .mapper("mapper")
                        .xml("mapper")
                        .pathInfo(Collections.singletonMap(OutputFile.xml, System.getProperty("user.dir")+"/src/main/resources/mapper"))
                )
                // 策略配置
                .strategyConfig((scanner, builder) -> {
                    builder.addInclude(getTableNames(scanner.apply("==================策略配置====================\n请输入表名，多个英文逗号分隔？所有输入 all")))
                            .serviceBuilder()
                            .controllerBuilder()
                            .enableRestStyle()
                            .enableHyphenStyle()
                            .entityBuilder()
                            .enableLombok()
                            .enableChainModel();
                })
                .execute();
    }

    // 处理 all 情况
    protected static List<String> getTableNames(String tableNames) {
        return "all".equals(tables) ? Collections.emptyList() : Arrays.asList(tables.split(","));
    }
}
