springboot整合mybatisPlus代码生成器 快速生成controller service mapper

1：引入依赖

       
        <dependency>
            <groupId>com.baomidougroupId>
            <artifactId>mybatis-plus-generatorartifactId>
            <version>3.3.1.tmpversion>
        dependency>
        
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <scope>runtimescope>
            <version>8.0.19version>
        dependency>

            <artifactId>lombokartifactId>
            <optional>trueoptional>
        dependency>

2：编写启动类

3 使用

3.1 启动 输入模块名 输入表面（多个表需要生成时候，英文逗号分割）

4 效果

4.1 生成的目录

4.2 生成的代码

4.2.1 entity

package cloud.xingzhe.generator.test.entity;

import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableId;
import java.io.Serializable;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.experimental.Accessors;

/**
 * 

 * 
 * 
 *
 * @author 行者
 * @since 2020-05-02
 */
@Data
@EqualsAndHashCode(callSuper = false)
@Accessors(chain = true)
@ApiModel(value="SysUser对象", description="")
public class SysUser implements Serializable {

    private static final long serialVersionUID = 1L;

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

    @ApiModelProperty(value = "用户名")
    private String username;

    @ApiModelProperty(value = "地址")
    private String address;
}

4.2.2 controller

package cloud.xingzhe.generator.test.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * 

 *  前端控制器
 * 
 *
 * @author 行者
 * @since 2020-05-02
 */
@RestController
@RequestMapping("/test/sys-user")
public class SysUserController {

}

4.2.3 service

package cloud.xingzhe.generator.test.service;
import cloud.xingzhe.generator.test.entity.SysUser;
import com.baomidou.mybatisplus.extension.service.IService;
/**
 * 

 *  服务类
 * 
 * @author 行者
 * @since 2020-05-02
 */
public interface ISysUserService extends IService<SysUser> {

}

4.2.4 serviceImpl

package cloud.xingzhe.generator.test.service.impl;
import cloud.xingzhe.generator.test.entity.SysUser;
import cloud.xingzhe.generator.test.mapper.SysUserMapper;
import cloud.xingzhe.generator.test.service.ISysUserService;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import org.springframework.stereotype.Service;
/**
 * 

 *  服务实现类
 * 
 * @author 行者
 * @since 2020-05-02
 */
@Service
public class SysUserServiceImpl extends ServiceImpl<SysUserMapper, SysUser> implements ISysUserService {

}

4.2.5 mapper.java

package cloud.xingzhe.generator.test.mapper;

import cloud.xingzhe.generator.test.entity.SysUser;
import com.baomidou.mybatisplus.core.mapper.BaseMapper;

/**
 * 

 *  Mapper 接口
 * 
 *
 * @author 行者
 * @since 2020-05-02
 */
public interface SysUserMapper extends BaseMapper<SysUser> {

}

4.2.5 mapper.xml

<mapper namespace="cloud.xingzhe.generator.test.mapper.SysUserMapper">

mapper>
