1、安装插件

Easycode是idea的一个插件，可以直接对数据的表生成entity、controller、service、dao、mapper无需任何编码，简单而强大。

2、在IDEA配置链接数据库

3、配置生成模板

controller层

$!init
##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Controller"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".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 $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import $!{tableInfo.savePackageName}.service.$!{tableInfo.name}Service;
import org.springframework.web.bind.annotation.*;
import java.util.List;
import javax.annotation.Resource;


/**
 * $!{tableInfo.comment}
 * Copyright (C), 2022, vivo
 * @Author: hou
 * @Date: $!time.currTime()
 * @version 1.0.0
 */
@RestController
@RequestMapping("$!tool.firstLowerCase($tableInfo.name)")
public class $!{tableName} {
    
    @Resource
    private $!{tableInfo.name}Service $!tool.firstLowerCase($tableInfo.name)Service;

}

entity实体

$!init
##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;
import lombok.Data;

/**
 * $!{tableInfo.comment}实体类
 * Copyright (C), 2022, vivo
 * @Author: hou
 * @Date: $!time.currTime()
 * @version 1.0.0
 */
@Data
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


}

service层

$!init
##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Service"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/service"))

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

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

import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import java.util.List;

/**
 * $!{tableInfo.comment}service层
 * Copyright (C), 2022, vivo
 * @Author: 72161681
 * @Date: $!time.currTime()
 * @version 1.0.0
 */
public interface $!{tableName} {

}

serviceImpl层

$!init
##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "ServiceImpl"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".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;

import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import $!{tableInfo.savePackageName}.mapper.$!{tableInfo.name}Mapper;
import $!{tableInfo.savePackageName}.service.$!{tableInfo.name}Service;
import org.springframework.stereotype.Service;
import java.util.List;
import javax.annotation.Resource;

/**

 */
@Service("$!tool.firstLowerCase($!{tableInfo.name})Service")
public class $!{tableName} implements $!{tableInfo.name}Service {
    @Resource
    private $!{tableInfo.name}Mapper $!tool.firstLowerCase($!{tableInfo.name})Mapper;

}

mapper层

$!init
##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Mapper"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/mapper"))

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

 */
public interface $!{tableName} {

数据表xml

##引入mybatis支持
$!{mybatisSupport.vm}

##设置保存名称与保存位置
$!callback.setFileName($tool.append($!{tableInfo.name}, "Mapper.xml"))
$!callback.setSavePath($tool.append($modulePath, "/src/main/resources/mapper"))

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