EasyCode, a must-have development artifact for IDEA

Table of contents

1 Introduction

2. Install (EasyCode)

3. Create a database

4. Configure the connection database in IDEA

5. Start generating code

6、pom.xml

7、Application.yml

8. Start the project

1 Introduction

Easycode is a plug-in of idea, which can directly generate entity, controller, service, dao, mapper for the data table, without any coding, simple and powerful.

2. Install (EasyCode)

Open Plugins–>Marketplace in Sittings of idea, search for EasyCode, click Install and restart

What I say here is that it is already installed.

It is recommended that you install a plugin called Lombok.
Lombok can automatically generate constructors, getter/setter, equals, hashcode, and toString methods for attributes at compile time through annotations. The magic that appears is that there are no getter and setter methods in the source code, but there are getter and setter methods in the compiled bytecode file.

3. Create a database

-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL,
  `username` varchar(20) DEFAULT NULL,
  `sex` varchar(6) DEFAULT NULL,
  `birthday` date DEFAULT NULL,
  `address` varchar(20) DEFAULT NULL,
  `password` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
SET FOREIGN_KEY_CHECKS = 1;

4. Configure the connection database in IDEA

Before this, create a new Springboot project, which should be relatively simple.

After building the SpringBoot project, as shown in the figure below, find the Database

Take oracle as an example:

Configure database connection information:

5. The code generator generates code

Right-click the table that needs to generate code, select EasyCode–>Generate Code

Make the following selections in the pop-up box, remember to select your corresponding Package

The corresponding class has been generated in the right directory

The above is how to install easy code and how to automatically generate code and mapper in idea. Let's introduce the detailed configuration of easy code

5. Introduction to the configuration of esay code

Open Other Settings–>Easy Code

6, Type Mapper arrangement

7. Template Setting configuration

** Default**

Template Setting里面 生成的类和mapper的配置脚本，根据本人的开发习惯，整理出一套集成lombok和swagger的脚本，仅供参考

7.1、entity.java.vm

##引入宏定义
$!{define.vm}

##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.vm}
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})/**
     * ${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

}

7.2、mapper.java.vm

##定义初始变量

##设置回调

##拿到主键
#if(!$tableInfo.pkColumn.isEmpty())
    #set($pk = $tableInfo.pkColumn.get(0))
#end

8、Global Config配置

去掉表前缀设置

去掉表的t_前缀

!tableInfo.setName(tool.getClassName($tableInfo.obj.name.replaceFirst("T_","")))

这里只是简单的一些模板配置，如果你对EasyCode很感兴趣的话，可以尝试在官网多进行了解：

地址：

gitee：EasyCode: EasyCode是基于IntelliJ IDEA开发的代码生成插件，支持自定义任意模板(Java，html，js，xml)。只要是与数据库相关的代码都可以通过自定义模板来生成。支持数据库类型与java类型映射关系配置。支持同时生成生成多张表的代码。每张表有独立的配置信息。完全的个性化定义，规则由你设置。
