工具—IDEA代码自动生成插件EasyCode

简介

官网简介

• 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。

背景

枯燥繁琐的CRUD，不如自动生成自己喜欢的代码风格

教程

1、安装EasyCode插件

二、 配置代码模板

模板配置路径

1、Type Mapper类型映射

根据自己实际情况对应数据表结构类型与Java类型

2、Template代码模板

这里使用的是默认模板Defaul，可保留原插件默认模板，新建自己Group Name组名

2.1、Template代码模板：controller.java.vm

##引入宏定义
$!{define.vm}

##定义初始变量
#set($controllerName = $tool.append($tableInfo.name, "Controller"))
##实体类名
#set($entityName = $tool.append($tableInfo.name, "Entity"))
#set($queryPage = $tool.append("query", $tableInfo.name, "Page"))
#set($queryList = $tool.append("query", $tableInfo.name, "List"))
#set($queryById = $tool.append("query", $tableInfo.name, "ById"))
#set($save = $tool.append("save", $tableInfo.name))
#set($update = $tool.append("update", $tableInfo.name))
#set($delete = $tool.append("delete", $tableInfo.name, "ById"))

##设置回调
$!callback.setFileName($tool.append($controllerName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/controller"))
##拿到主键
#if(!$tableInfo.pkColumn.isEmpty())
    #set($pk = $tableInfo.pkColumn.get(0))
#end

#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}controller;

import $!{tableInfo.savePackageName}.entity.$entityName;

2.5、Template代码模板：service.java.vm

##引入宏定义

##设置回调

##拿到主键

##使用宏定义实现类注释信息

    Boolean $delete($!pk.shortType $!pk.name);
}

2.6、Template代码模板：serviceImpl.java.vm

##引入宏定义
$!{define.vm}
$!{init.vm}

##定义初始变量
#set($serviceImplName = $tool.append($tableInfo.name, "ServiceImpl"))
##实体类名
#set($entityName = $tool.append($tableInfo.name, "Entity"))
#set($serviceName = $tool.append($tableInfo.name, "Service"))
#set($daoName = $tool.append($tableInfo.name, "Dao"))
#set($queryPage = $tool.append("query", $tableInfo.name, "Page"))
#set($queryList = $tool.append("query", $tableInfo.name, "List"))
#set($queryById = $tool.append("query", $tableInfo.name, "ById"))
#set($save = $tool.append("save", $tableInfo.name))
#set($update = $tool.append("update", $tableInfo.name))
#set($delete = $tool.append("delete", $tableInfo.name, "ById"))

##设置回调
$!callback.setFileName($tool.append($serviceImplName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/service/impl"))

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

#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}service.impl;

}

3、Column Config配置

4、Global Config配置

4.1、Global Config配置：autoImport.vm

##自动导入包（仅导入实体属性需要的包，通常用于实体类）
#foreach($import in $importList)
import $!import;
#end

4.2、Global Config配置：define.vm

##（Velocity宏定义）

##定义设置表名后缀的宏定义，调用方式：#setTableSuffix("Test")
#macro(setTableSuffix $suffix)
    #set($tableName = $!tool.append($tableInfo.name, $suffix))
#end

##定义设置包名后缀的宏定义，调用方式：#setPackageSuffix("Test")
#macro(setPackageSuffix $suffix)
#if($suffix!="")package #end#if($tableInfo.savePackageName!="")$!{tableInfo.savePackageName}.#{end}$!suffix;
#end

##定义直接保存路径与文件名简化的宏定义，调用方式：#save("/entity", ".java")
#macro(save $path $fileName)
    $!callback.setSavePath($tool.append($tableInfo.savePath, $path))
    $!callback.setFileName($tool.append($tableInfo.name, $fileName))
#end

##定义表注释的宏定义，调用方式：#tableComment("注释信息")
#macro(tableComment $desc)
/**
 * $!{tableInfo.comment}--$desc
 * @Author: ClancyLv
 * @Date: $!time.currTime()
 * @Description: $!{tableInfo.comment}
 */
#end

##定义GET，SET方法的宏定义，调用方式：#getSetMethod($column)
#macro(getSetMethod $column)

    public $!{tool.getClsNameByFullName($column.type)} get$!{tool.firstUpperCase($column.name)}() {
        return $!{column.name};
    }

    public void set$!{tool.firstUpperCase($column.name)}($!{tool.getClsNameByFullName($column.type)} $!{column.name}) {
        this.$!{column.name} = $!{column.name};
    }
#end

4.3、Global Config配置：init.vm

##初始化区域

##去掉表的t_前缀
$!tableInfo.setName($tool.getClassName($tableInfo.obj.name.replaceFirst("book_","")))

##参考阿里巴巴开发手册，POJO 类中布尔类型的变量，都不要加 is 前缀，否则部分框架解析会引起序列化错误
#foreach($column in $tableInfo.fullColumn)
#if($column.name.startsWith("is") && $column.type.equals("java.lang.Boolean"))
    $!column.setName($tool.firstLowerCase($column.name.substring(2)))
#end
#end

##实现动态排除列，这里排除了通用类BaseEntity中的字段
#set($temp = $tool.newHashSet("delFlg", "createId", "updateId", "createTime", "updateTime", "remark"))
#foreach($item in $temp)
    #set($newList = $tool.newArrayList())
    #foreach($column in $tableInfo.fullColumn)
        #if($column.name!=$item)
            ##带有反回值的方法调用时使用$tool.call来消除返回值
            $tool.call($newList.add($column))
        #end
    #end
    ##重新保存
    $tableInfo.setFullColumn($newList)
#end

##对importList进行篡改
#set($temp = $tool.newHashSet())
#foreach($column in $tableInfo.fullColumn)
    #if(!$column.type.startsWith("java.lang."))
        ##带有反回值的方法调用时使用$tool.call来消除返回值
        $tool.call($temp.add($column.type))
    #end
#end
##覆盖
#set($importList = $temp)

4.4、Global Config配置：mybatisSupport.vm

##针对Mybatis 进行支持，主要用于生成xml文件
#foreach($column in $tableInfo.fullColumn)
    ##储存列类型
    $tool.call($column.ext.put("sqlType", $tool.getField($column.obj.dataType, "typeName")))
    #if($tool.newHashSet("java.lang.String").contains($column.type))
        #set($jdbcType="VARCHAR")
    #elseif($tool.newHashSet("java.lang.Boolean", "boolean").contains($column.type))
        #set($jdbcType="BOOLEAN")
    #elseif($tool.newHashSet("java.lang.Byte", "byte").contains($column.type))
        #set($jdbcType="BYTE")
    #elseif($tool.newHashSet("java.lang.Integer", "int", "java.lang.Short", "short").contains($column.type))
        #set($jdbcType="INTEGER")
    #elseif($tool.newHashSet("java.lang.Long", "long").contains($column.type))
        #set($jdbcType="INTEGER")
    #elseif($tool.newHashSet("java.lang.Float", "float", "java.lang.Double", "double").contains($column.type))
        #set($jdbcType="NUMERIC")
    #elseif($tool.newHashSet("java.util.Date", "java.sql.Timestamp", "java.time.Instant", "java.time.LocalDateTime", "java.time.OffsetDateTime", "	java.time.ZonedDateTime").contains($column.type))
        #set($jdbcType="TIMESTAMP")
    #elseif($tool.newHashSet("java.sql.Date", "java.time.LocalDate").contains($column.type))
        #set($jdbcType="TIMESTAMP")
    #else
        ##其他类型
        #set($jdbcType="VARCHAR")
    #end
    $tool.call($column.ext.put("jdbcType", $jdbcType))
#end

##定义宏，查询所有列
#macro(allSqlColumn)#foreach($column in $tableInfo.fullColumn)$column.obj.name#if($velocityHasNext), #end#end#end

三、 使用

1、连接数据库

2、选择

3、配置

补充包基础路径（不用到具体dao或entity或…层）
选择组名，与配置模板选定的组名一致
选择要生成代码的模板
点击OK
