一、前言

此文将分享我个人使用的一个easycode生成方法,生成之后可以直接运行,这也就意味着,生成的代码会更加规范化。规范化就意味着会有更多的约束。

二、正文

2.1 基础前提

2.1.1springboot配置

引入所需jar包
pom.xml加入一下依赖

application.yml配置

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://ip:3306/dbname?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
    username: xxx
    password: xxx

mybatis:
  type-aliases-package: xxx.entity
  mapper-locations: classpath:mapper
public class PageRequest {
    
    private int pageNum;
    
    private int pageSize;

    public PageRequest(int start, int limit) {
        pageNum=start;
        pageSize=limit;
    }

    public int getPageNum() {
        return pageNum;
    }
    public void setPageNum(int pageNum) {
        this.pageNum = pageNum;
    }
    public int getPageSize() {
        return pageSize;
    }
    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }
}

在page目录新建类PageResult.java

package xxx.common.page;

import java.util.List;


public class PageResult {
    
    private int pageNum;
    
    private int pageSize;
    
    private long totalSize;
    
    private int totalPages;
    
    private List<?> content;

    public int getPageNum() {
        return pageNum;
    }

    public void setPageNum(int pageNum) {
        this.pageNum = pageNum;
    }

    public int getPageSize() {
        return pageSize;
    }

    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    public long getTotalSize() {
        return totalSize;
    }

    public void setTotalSize(long totalSize) {
        this.totalSize = totalSize;
    }

    public int getTotalPages() {
        return totalPages;
    }

    public void setTotalPages(int totalPages) {
        this.totalPages = totalPages;
    }

    public List<?> getContent() {
        return content;
    }

    public void setContent(List<?> content) {
        this.content = content;
    }
}

在util目录下新建工具类PageUtils.java

package xxx.common.util;

import com.github.pagehelper.PageInfo;
import xxx.common.page.PageRequest;
import xxx.common.page.PageResult;


public class PageUtils {

    
    public static PageResult getPageResult(PageRequest pageRequest, PageInfo<?> pageInfo) {
        PageResult pageResult = new PageResult();
        pageResult.setPageNum(pageInfo.getPageNum());
        pageResult.setPageSize(pageInfo.getPageSize());
        pageResult.setTotalSize(pageInfo.getTotal());
        pageResult.setTotalPages(pageInfo.getPages());
        pageResult.setContent(pageInfo.getList());
        return pageResult;
    }
}

统一返回体
在common目录下新建Status.java

package xxx.common;


public enum Status {

    FAIL("101", "失败")
    ,GET_FAIL("111", "查询失败")
    ,ADD_FAIL("121", "添加失败")
    ,DELETE_FAIL("131", "删除失败")
    ,UPDATE_FAIL("141", "修改失败")
    ,SUCCESS("100", "成功")
    ,GET_SUCCESS("110", "查询成功")
    ,ADD_SUCCESS("120", "添加成功")
    ,DELETE_SUCCESS("130", "删除成功")
    ,UPDATE_SUCCESS("140", "修改成功")
    ,ERROR("201", "错误")
    ,USER_NOFOUND("211", "用户不存在")
    ,ERROR_ACCOUNT("212", "账号或密码错误")
    ,USER_EXIST("213", "用户已存在")
    ,USER_LOCK("214", "账号被锁定,请联系管理员")
    ,IP_LOCK("215", "IP 被锁定,请联系管理员")
    ,PARAM_ERROR("303", "参数错误")
    ,Token_Expired("1044", "token Invalid expired");

    public String status; // 状态码
    public String msg; // 提示语

    Status(String status, String msg) {
        this.status = status;
        this.msg = msg;
    }

}

在common目录下新建ReturnData.java

package xxx.common;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.SerializerFeature;


public class ReturnData<T> {
    private String status; // 状态码

        return new ReturnData<T>(Status.UPDATE_SUCCESS.status, Status.UPDATE_SUCCESS.msg);
    }

    public static <T> ReturnData<T> UPDATE_SUCCESS(T data) {
        return new ReturnData<T>(Status.UPDATE_SUCCESS.status, Status.UPDATE_SUCCESS.msg,data);
    }

    public static <T> ReturnData<T> FAIL(String msg) {
        return new ReturnData<T>(Status.FAIL.status, msg);
    }

    public static <T> ReturnData<T> FAIL() {
        return new ReturnData<T>(Status.FAIL.status, Status.FAIL.msg);
    }

    public static <T> ReturnData<T> GET_FAIL(String msg) {
        return new ReturnData<T>(Status.GET_FAIL.status, msg);
    }

    public static <T> ReturnData<T> GET_FAIL() {
        return new ReturnData<T>(Status.GET_FAIL.status, Status.FAIL.msg);
    }


    public static <T> ReturnData<T> ADD_FAIL() {
        return new ReturnData<T>(Status.ADD_FAIL.status, Status.ADD_FAIL.msg);
    }

    public static <T> ReturnData<T> DELETE_FAIL() {
        return new ReturnData<T>(Status.DELETE_FAIL.status, Status.DELETE_FAIL.msg);
    }

    public static <T> ReturnData<T> UPDATE_FAIL() {
        return new ReturnData<T>(Status.UPDATE_FAIL.status, Status.UPDATE_FAIL.msg);

    }


    public ReturnData(String status, String msg, T data) {
        this.status = status;
        this.msg = msg;
        this.data = data;
    }

    public ReturnData(String status, String msg) {
        this.status = status;
        this.msg = msg;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }

    
    @Override
    public String toString() {
        return JSON.toJSONString(this);
    }

    
    public String toAllString() {
        return JSON.toJSONString(this, SerializerFeature.WriteMapNullValue);
    }

}

swagger3配置
在common目录下新建Swagger3Config.java

package xxx.common;

import io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;


@Configuration
public class Swagger3Config {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.OAS_30)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("xxx.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Swagger3接口文档")
                .description("测试API")
                .contact(new Contact("测试API", "http://localhost:8080/swagger-ui/index.html", "1757895437@qq.com"))
                .version("1.0")
                .build();
    }
}

2.2 模板设置

2.2.1安装idea插件:EasyCode

在这里插入图片描述

如图所示,打开idea的设置界面,选择插件,搜索EasyCode,点击安装即可

2.2.2 设置模板

在这里插入图片描述

如图:依次打开idea设置-> 其他设置->EasyCode-MyBatisCodeHelper->Template Setting
右边的就是生成代码的模板,一次将下列模板粘贴到里面即可:

entity

##引入宏定义
$!define

##使用宏定义设置回调(保存位置与文件后缀)
#save("/entity", ".java")

##使用宏定义设置包后缀
#setPackageSuffix("entity")

##使用全局变量实现默认包导入
$!autoImport
import java.io.Serializable;

##使用宏定义实现类注释信息
#tableComment("实体类")
public class $!{tableInfo.name} implements Serializable {
    private static final long serialVersionUID = $!tool.serial();
#foreach($column in $tableInfo.fullColumn)
    #if(${column.comment})#end

    private $!{tool.getClsNameByFullName($column.type)} $!{column.name};
#end

#foreach($column in $tableInfo.fullColumn)
    ##使用宏定义实现get,set方法
    #getSetMethod($column)
#end

    @Override
    public String toString(){
        return "$tableInfo.name {" +
        #foreach($column in $tableInfo.fullColumn)

2.3 生成方法

首先使用idea连接数据库,此处省略,如果有不知道怎么连接的,请参考:mysql连接idea详细教程 

在这里插入图片描述

在这里插入图片描述

如图选择需要生成代码的表->右键->EasyCodeMybatisCodeHelper->Generate_Code,弹出如下窗口

在这里插入图片描述

Module:选择要生成到那个模块
Package:填写自己的包名
Path:工程路径

选择要生成的类,点击ok即可看到工程里已经生成了相应的类

在这里插入图片描述

注意:使用mybatis需要在启动类中加入注释 

//扫描dao的路径配置
@MapperScan(".dao")
