使用 EasyCode生成springboot+mybatis基礎程序的實現示例

Posted on by

一、前言

此文將分享我個人使用的一個easycode生成方法，生成之後可以直接運行，這也就意味著，生成的代碼會更加規范化。規范化就意味著會有更多的約束。

二、正文

2.1 基礎前提

2.1.1springboot配置

引入所需jar包
pom.xml加入一下依賴

application.yml配置

2.1.1 基礎工具類

以下是我個人封裝的pagehelper分頁工具類和統一的返回以及swagger配置

pagehelper工具類

在這裡插入圖片描述

如上圖所示，在啟動類所在目錄下新建目錄common.page/common.util
在page目錄新建類PageRequest.java

package xxx.common.page;

/**
 * @author Zhiwei Wang
 * @version $1.0
 * @description 分頁請求
 * @date 2022/1/19 9:25
 * @history
 */
public class PageRequest {
    /**
     * 當前頁碼
     */
    private int pageNum;
    /**
     * 每頁數量
     */
    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目錄新建類PageResult.java

package xxx.common.page;

import java.util.List;

/**
 * @author Zhiwei Wang
 * @version $1.0
 * @name PageResult
 * @description 分頁返回結果
 * @date 2022/1/19 9:25
 * @history
 */
public class PageResult {
    /**
     * 當前頁碼
     */
    private int pageNum;
    /**
     * 每頁數量
     */
    private int pageSize;
    /**
     * 記錄總數
     */
    private long totalSize;
    /**
     * 頁碼總數
     */
    private int totalPages;
    /**
     * 數據模型
     */
    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目錄下新建工具類PageUtils.java

package xxx.common.util;

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

/**
 * @author Zhiwei Wang
 * @version $
 * @name PageUtil
 * @description 
 * @date 2022/1/19 9:26
 * @history
 */
public class PageUtils {

    /**
     * 將分頁信息封裝到統一的接口
     * @param pageRequest
     * @param pageInfo
     * @return
     */
    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;
    }
}

統一返回體
在common目錄下新建Status.java

package xxx.common;

/**
 * @author Zhiwei Wang
 * @version $
 * @name Status
 * @description 返回信息枚舉
 * @date 2022/1/18 21:01
 * @history
 */
public enum Status {

    FAIL("101", "失敗")
    ,GET_FAIL("111", "查詢失敗")
    ,ADD_FAIL("121", "添加失敗")
    ,DELETE_FAIL("131", "刪除失敗")
    ,UPDATE_FAIL("141", "修改失敗")
    ,SUCCESS("100", "成功")
    ,GET_SUCCESS("110", "查詢成功")
    ,ADD_SUCCESS("120", "添加成功")
    ,DELETE_SUCCESS("130", "刪除成功")
    ,UPDATE_SUCCESS("140", "修改成功")
    ,ERROR("201", "錯誤")
    ,USER_NOFOUND("211", "用戶不存在")
    ,ERROR_ACCOUNT("212", "賬號或密碼錯誤")
    ,USER_EXIST("213", "用戶已存在")
    ,USER_LOCK("214", "賬號被鎖定，請聯系管理員")
    ,IP_LOCK("215", "IP 被鎖定，請聯系管理員")
    ,PARAM_ERROR("303", "參數錯誤")
    ,Token_Expired("1044", "token Invalid expired");

    public String status; // 狀態碼
    public String msg; // 提示語

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

}

在common目錄下新建ReturnData.java

package xxx.common;

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

/**
 * @author Zhiwei Wang
 * @version $
 * @name ReturnData
 * @description 響應數據結構封裝
 * @date 2022/1/18 20:59
 * @history
 */
public class ReturnData<T> {
    private String status; // 狀態碼

    private String msg; // 提示語

    private T data;  // 數據集合

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

    }

    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.ERROR.status, msg);
    }

    public static <T> ReturnData<T> ERROR() {
        return new ReturnData<T>(Status.ERROR.status, Status.ERROR.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) {

    public T getData() {

    /**

     */
    public String toAllString() {

swagger3配置
在common目錄下新建Swagger3Config.java

package xxx.common;

 */
@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接口文檔")
                .description("測試API")
                .contact(new Contact("測試API", "http://localhost:8080/swagger-ui/index.html", "[email protected]"))
                .version("1.0")
                .build();
    }
}

2.2 模板設置

2.2.1安裝idea插件:EasyCode

在這裡插入圖片描述

如圖所示，打開idea的設置界面，選擇插件，搜索EasyCode，點擊安裝即可

2.2.2 設置模板

在這裡插入圖片描述

如圖：依次打開idea設置-> 其他設置->EasyCode-MyBatisCodeHelper->Template Setting
右邊的就是生成代碼的模板，一次將下列模板粘貼到裡面即可:

entity

##引入宏定義
$!define

##使用宏定義設置回調（保存位置與文件後綴）
#save("/entity", ".java")

##使用宏定義設置包後綴
#setPackageSuffix("entity")

##使用全局變量實現默認包導入
$!autoImport
import java.io.Serializable;

##使用宏定義實現類註釋信息
#tableComment("實體類")
public class $!{tableInfo.name} implements Serializable {
    private static final long serialVersionUID = $!tool.serial();
#foreach($column in $tableInfo.fullColumn)
    #if(${column.comment})/**
    * ${column.comment}
    */#end

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

#foreach($column in $tableInfo.fullColumn)
    ##使用宏定義實現get,set方法
    #getSetMethod($column)
#end

    @Override
    public String toString(){
        return "$tableInfo.name {" +
        #foreach($column in $tableInfo.fullColumn)
    "$column.name : " + $column.name + ", " +
        #end        
'}';
    }

2.3 生成方法

首先使用idea連接數據庫，此處省略，如果有不知道怎麼連接的，請參考：mysql連接idea詳細教程 

在這裡插入圖片描述

在這裡插入圖片描述

如圖選擇需要生成代碼的表->右鍵->EasyCodeMybatisCodeHelper->Generate_Code,彈出如下窗口

在這裡插入圖片描述

Module：選擇要生成到那個模塊
Package：填寫自己的包名
Path:工程路徑

選擇要生成的類，點擊ok即可看到工程裡已經生成瞭相應的類

在這裡插入圖片描述

註意：使用mybatis需要在啟動類中加入註釋 

//掃描dao的路徑配置
@MapperScan(".dao")
