MyBatisPlus--代码生成器

官网地址：代码生成器（新） | MyBatis-Plus (baomidou.com)

在pom.xml中引入

    com.baomidou
    mybatis-plus-generator
    3.5.1


    org.freemarker
    freemarker
    2.3.31

创建一个测试类，路径为src/test/java/com/mybatisplus_demo/FastAutoGeneratorTest.java

package com.mybatisplus_demo;

import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;
import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;

import java.util.Collections;

public class FastAutoGeneratorTest {
    public static void main(String[] args) {
        FastAutoGenerator.create("jdbc:mysql://127.0.0.1:3306/mybatis_plus?characterEncoding=utf-8&userSSL=false", "root", "123456")
                .globalConfig(builder -> {
                    builder.author("aiw") // 设置作者
                            //.enableSwagger() // 开启 swagger 模式
                            .fileOverride() // 覆盖已生成文件
                            .outputDir("E://IdeaProjects//MyBatis-Plus//mybatis_plus"); // 指定输出目录
                })
                .packageConfig(builder -> {
                    builder.parent("com.aiw") // 设置父包名
                            .moduleName("mybatisplus") // 设置父包模块名
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml, "E://IdeaProjects//MyBatis-Plus//mybatis_plus"));// 设置mapperXml生成路径
                })
                .strategyConfig(builder -> {
                    builder.addInclude("t_user") // 设置需要生成的表名
                            .addTablePrefix("t_", "c_"); // 设置过滤表前缀
                })
                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板，默认的是Velocity引擎模板
                .execute();
    }
}

运行完成后，自动打开输出目录：

将生成的项目使用IDEA打开，项目结构如下：

依次查看文件如下：

package com.aiw.mybatisplus.controller;


import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.stereotype.Controller;


@Controller
@RequestMapping("/mybatisplus/user")
public class UserController {

}

package com.aiw.mybatisplus.entity;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;
import java.io.Serializable;


@TableName("t_user")
public class User implements Serializable {

    private static final long serialVersionUID = 1L;

    
    @TableId(value = "id", type = IdType.AUTO)
    private Long id;

    
    private String name;

    
    private Integer age;

    
    private String email;

    
    private Integer sex;

    
    private Integer isDeleted;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
    public Integer getSex() {
        return sex;
    }

    public void setSex(Integer sex) {
        this.sex = sex;
    }
    public Integer getIsDeleted() {
        return isDeleted;
    }

    public void setIsDeleted(Integer isDeleted) {
        this.isDeleted = isDeleted;
    }

    @Override
    public String toString() {
        return "User{" +
            "id=" + id +
            ", name=" + name +
            ", age=" + age +
            ", email=" + email +
            ", sex=" + sex +
            ", isDeleted=" + isDeleted +
        "}";
    }
}

package com.aiw.mybatisplus.mapper;

import com.aiw.mybatisplus.entity.User;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;


public interface UserMapper extends BaseMapper {

}

package com.aiw.mybatisplus.service.impl;

import com.aiw.mybatisplus.entity.User;
import com.aiw.mybatisplus.mapper.UserMapper;
import com.aiw.mybatisplus.service.IUserService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;


@Service
public class UserServiceImpl extends ServiceImpl implements IUserService {

}

package com.aiw.mybatisplus.service;

import com.aiw.mybatisplus.entity.User;
import com.baomidou.mybatisplus.extension.service.IService;


public interface IUserService extends IService {

}

在IDEA中打开项目，仔细观察可以发现大部分代码爆红，一般来说将生成的代码拷贝到Maven项目中，然后导入相关依赖即可
