idea--springboot的增删改查的代码以及配置文件之代码（实体类，mapper文件，service和control，启动类）

实体类：

package com.zdc.entity;

public class GgCzyb {
    private String id;
    private String mc;
    private String dlh;
    private String name;
    private String phone;
    private String email;
    private Integer type;

    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getMc() {
        return mc;
    }
    public void setMc(String mc) {
        this.mc = mc;
    }
    public String getDlh() {
        return dlh;
    }
    public void setDlh(String dlh) {
        this.dlh = dlh;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPhone() {
        return phone;
    }
    public void setPhone(String phone) {
        this.phone = phone;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public Integer getType() {
        return type;
    }
    public void setType(Integer type) {
        this.type = type;
    }
}

mapper接口

package com.zdc.mapper;

import com.zdc.entity.GgCzyb;

import java.util.List;

public interface GgCzybMapper {

    int create(GgCzyb ggCzyb);

    int delete(String ggCzybId);

    int update(GgCzyb ggCzyb);

    List<GgCzyb> query(GgCzyb ggCzyb);

    GgCzyb detail(String ggCzybId);

}

mapper.xml文件（增删改查sql片段等）

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper  PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

    </sql>

    <select id="detail" resultMap="ggczyb">

    </select>

</mapper>

service文件

package com.zdc.service;

import com.zdc.entity.GgCzyb;
import com.zdc.mapper.GgCzybMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

    }

    public GgCzyb detail(String ggCzybId){
        return  ggCzybMapper.detail(ggCzybId);
    }

}

@SpringBootApplication
@MapperScan({"com.zdc.mapper"})
