自创的安卓代码生成器-生成SpringBoot工程文件
大家好，我是飞刀，这次我来讲一下生成SpringBoot工程文件的功能。
首先打开界面看一下：
这个功能也不是安卓使用的，而是我自己开发SpringBoot项目时使用的。
输入一个实体类：
public class Feedback {
private String phone;
private String content;
private Date createDatetime;
}
点击生成，结果如下：
输出框生成的代码：
package com.zheng.boot.entity;
import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;
import java.util.Date;
@Data
public class Feedback {
private String phone;
private String content;
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
private Date createDatetime;
}
package com.zheng.boot.controller;
import com.zheng.boot.common.JsonResult;
import com.zheng.boot.entity.Feedback;
import com.zheng.boot.service.FeedbackService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.Date;
import java.util.List;
@RestController
@RequestMapping("feedback")
public class FeedbackController {
@Autowired
FeedbackService feedbackService;
/**
* 插入
*/
@RequestMapping(value = {"/insert"})
public JsonResult<Feedback> insert(String phone, String content) {
if (content == null) {
return new JsonResult(-1, "content不能为空");
}
Feedback feedback = new Feedback();
feedback.setPhone(phone);
feedback.setContent(content);
feedback.setCreateDatetime(new Date());
int count = feedbackService.insert(feedback);
if (count > 0) {
return new JsonResult(0, "插入成功");
} else {
return new JsonResult(-1, "插入失败");
}
}
/**
* 删除
*/
@RequestMapping(value = {"/delete"})
public JsonResult<Feedback> delete(String phone) {
if (phone == null) {
return new JsonResult(-1, "phone不能为空");
}
int count = feedbackService.deleteByPrimaryKey(phone);
if (count > 0) {
return new JsonResult(0, "删除成功");
} else {
return new JsonResult(-1, "删除失败");
}
}
/**
* 更新
*/
@RequestMapping(value = {"/update"})
public JsonResult<Feedback> update(String phone, String content) {
if (phone == null) {
return new JsonResult(-1, "phone不能为空");
}
Feedback feedback = new Feedback();
feedback.setPhone(phone);
feedback.setContent(content);
feedback.setCreateDatetime(new Date());
int count = feedbackService.updateByPrimaryKey(feedback);
if (count > 0) {
return new JsonResult(0, "更新成功");
} else {
return new JsonResult(-1, "更新失败");
}
}
/**
* 查询
*/
@RequestMapping(value = {"/select"})
public JsonResult<Feedback> select(String phone) {
if (phone == null) {
return new JsonResult(-1, "phone不能为空");
}
Feedback feedback = feedbackService.selectByPrimaryKey(phone);
if (feedback == null) {
return new JsonResult(-1, "查询信息不存在");
}
return new JsonResult(0, feedback);
}
/**
* 查询全部
*/
@RequestMapping(value = {"/selectAll"})
public JsonResult<List<Feedback>> selectAll() {
List<Feedback> feedbackList = feedbackService.selectAll();
return new JsonResult(0, feedbackList);
}
/**
* 查询分页
*/
@RequestMapping(value = {"/selectPage"})
public JsonResult<List<Feedback>> selectPage(Integer pageNum, Integer pageSize) {
List<Feedback> feedbackList = feedbackService.selectPage(pageNum, pageSize);
return new JsonResult(0, feedbackList);
}
}
package com.zheng.boot.service;
import com.zheng.boot.entity.Feedback;
import java.util.List;
public interface FeedbackService {
int insert(Feedback feedback);
int deleteByPrimaryKey(String phone);
int updateByPrimaryKey(Feedback feedback);
Feedback selectByPrimaryKey(String phone);
List<Feedback> selectAll();
List<Feedback> selectPage(Integer pageNum, Integer pageSize);
}
package com.zheng.boot.serviceImpl;
import com.github.pagehelper.PageHelper;
import com.zheng.boot.entity.Feedback;
import com.zheng.boot.mapper.FeedbackMapper;
import com.zheng.boot.service.FeedbackService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service
public class FeedbackServiceImpl implements FeedbackService {
@Autowired
FeedbackMapper feedbackMapper;
@Override
public int insert(Feedback feedback) {
return feedbackMapper.insert(feedback);
}
@Override
public int deleteByPrimaryKey(String phone) {
return feedbackMapper.deleteByPrimaryKey(phone);
}
@Override
public int updateByPrimaryKey(Feedback feedback) {
return feedbackMapper.updateByPrimaryKey(feedback);
}
@Override
public Feedback selectByPrimaryKey(String phone) {
return feedbackMapper.selectByPrimaryKey(phone);
}
@Override
public List<Feedback> selectAll() {
return feedbackMapper.select();
}
@Override
public List<Feedback> selectPage(Integer pageNum, Integer pageSize) {
PageHelper.startPage(pageNum,pageSize);
return feedbackMapper.select();
}
}
package com.zheng.boot.mapper;
import com.zheng.boot.entity.Feedback;
import java.util.List;
public interface FeedbackMapper {
int insert(Feedback feedback);
int deleteByPrimaryKey(String phone);
int updateByPrimaryKey(Feedback feedback);
Feedback selectByPrimaryKey(String phone);
List<Feedback> select();
}
<?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" >
<mapper namespace="com.zheng.boot.mapper.FeedbackMapper">
<resultMap id="BaseResultMap" type="Feedback">

<result column="phone" property="phone"/>
<result column="content" property="content"/>
<result column="create_datetime" property="createDatetime"/>
</resultMap>
<sql id="Base_Column_List">
phone, content, create_datetime
</sql>
<insert id="insert">
insert into feedback (phone, content, create_datetime)
values (#{phone}, #{content}, #{createDatetime})
</insert>
<delete id="deleteByPrimaryKey">
delete from feedback where phone = #{phone}
</delete>
<update id="updateByPrimaryKey">
update feedback set
content = #{content},
create_datetime = #{createDatetime}
where phone = #{phone}
</update>
<select id="selectByPrimaryKey" resultMap="BaseResultMap">
select <include refid="Base_Column_List"/> from feedback where phone = #{phone}
</select>
<select id="select" resultMap="BaseResultMap">
select * from feedback order by created desc
</select>
</mapper>
自动生成了SpringBoot各个层的增删改查代码，同样不需要复制这些代码，因为代码已经自动写入项目工程中了，看看截图:
首先实体类entity自动添加了lombok注解:
然后是Controller:
Service:
serviceImpl：
mapper:
以及mapper.xml:
最后再根据自己的需要稍微调整一下就可以了。
