以idea 2020.1为例，首先介绍一下 easy code的安装和使用说明

1、easy code 安装

打开idea的Sittings中的Plugins–>Marketplace，搜索EasyCode 点击安装 安装后重启

2、DB连接说明

以oracle为例：

3 、代码生成器生成代码

右击需要生成代码的表，选择EasyCode–>Generate Code

 弹出的框做如下选择，记得选择你对应的Package

 右侧目录已经生成对应的类了

以上是如何安装easy code和怎么在idea里面自动生成代码和mapper，下面来介绍一下easy code的详细配置

4、esay code的配置介绍

打开Other Settings–>Easy Code

5、 Type Mapper配置

6、Template Setting配置

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

6.1、entity.java

##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
$!autoImport
import java.io.Serializable;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
import javax.persistence.Column;
import javax.persistence.Id;
import javax.persistence.Table;##使用宏定义实现类注释信息
#tableComment("实体类")
@Data
@Table(name = "$tableInfo.obj.name")
public class $!{tableInfo.name} implements Serializable {private static final long serialVersionUID = $!tool.serial();
#foreach($column in $tableInfo.fullColumn)#if(${column.name} == "id")@Id#end
#if(${column.comment})@ApiModelProperty(value = "${column.comment}")#end
@Column(name = "$column.obj.name")private $!{tool.getClsNameByFullName($column.type)} $!{column.name};
#end
}

6.2、dao.java

##定义初始变量
#set($tableName = $tool.append($tableInfo.name, "Dao"))
##设置回调
$!callback.setFileName($tool.append($tableName, ".java"))
$!callback.setSavePath($tool.append($tableInfo.savePath, "/dao"))##拿到主键，暂且认为第一个字段为id的话，作为主键
#if(!$tableInfo.fullColumn.isEmpty())#if($tableInfo.fullColumn.get(0).name == "id")#set($pk = $tableInfo.fullColumn.get(0))#end
#end#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}dao;import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import $!{tableInfo.savePackageName}.config.Mapper;
import org.springframework.stereotype.Component;/*** $!{tableInfo.comment}($!{tableInfo.name})表数据库访问层* @author $!author* @since $!time.currTime()*/
@Component
public interface $!{tableName} extends Mapper<$tableInfo.name> {/*** 通过ID查询单条数据* @param $!pk.name 主键* @return 实例对象*/$!{tableInfo.name} queryById($!pk.shortType $!pk.name);
}

6.3、service.java

##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($tableInfo.savePath, "/service"))##拿到主键，暂且认为第一个字段为id的话，作为主键
#if(!$tableInfo.fullColumn.isEmpty())#if($tableInfo.fullColumn.get(0).name == "id")#set($pk = $tableInfo.fullColumn.get(0))#end
#end#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}service;import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};/*** $!{tableInfo.comment}($!{tableInfo.name})表服务接口* @author $!author* @since $!time.currTime()*/
public interface $!{tableName} {/*** 通过ID查询单条数据* @param $!pk.name 主键* @return 实例对象*/$!{tableInfo.name} queryById($!pk.shortType $!pk.name);
}

 6.4、serviceImpl.java

##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($tableInfo.savePath, "/service/impl"))##拿到主键，暂且认为第一个字段为id的话，作为主键
#if(!$tableInfo.fullColumn.isEmpty())#if($tableInfo.fullColumn.get(0).name == "id")#set($pk = $tableInfo.fullColumn.get(0))#end
#end#if($tableInfo.savePackageName)package $!{tableInfo.savePackageName}.#{end}service.impl;import $!{tableInfo.savePackageName}.entity.$!{tableInfo.name};
import $!{tableInfo.savePackageName}.dao.$!{tableInfo.name}Dao;
import $!{tableInfo.savePackageName}.service.$!{tableInfo.name}Service;
import org.springframework.stereotype.Service;import org.springframework.beans.factory.annotation.Autowired;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;/*** $!{tableInfo.comment}($!{tableInfo.name})表服务实现类* @author $!author* @since $!time.currTime()*/
@Service
public class $!{tableName} implements $!{tableInfo.name}Service {/** logger:日志文件 */private Logger logger = LoggerFactory.getLogger($!{tableName}.class);@Autowiredprivate $!{tableInfo.name}Dao $!tool.firstLowerCase($!{tableInfo.name})Dao;/*** 通过ID查询单条数据* @param $!pk.name 主键* @return 实例对象*/@Overridepublic $!{tableInfo.name} queryById($!pk.shortType $!pk.name) {return this.$!{tool.firstLowerCase($!{tableInfo.name})}Dao.queryById($!pk.name);}
}

 6.5、controller.java

##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($tableInfo.savePath, "/controller"))
##拿到主键，暂且认为第一个字段为id的话，作为主键
#if(!$tableInfo.fullColumn.isEmpty())#if($tableInfo.fullColumn.get(0).name == "id")#set($pk = $tableInfo.fullColumn.get(0))#end
#end#if($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 io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;/*** $!{tableInfo.comment}($!{tableInfo.name})表控制层* @author $!author* @since $!time.currTime()*/
@RestController
@RequestMapping(value = "/$!tool.firstLowerCase($tableInfo.name)", method = {RequestMethod.POST, RequestMethod.GET})
@Api(value = "$!{tableName}", tags = {"$!{tableInfo.comment}($!{tableInfo.name})表控制层"})
public class $!{tableName} {/** logger:日志文件 */private Logger logger = LoggerFactory.getLogger($!{tableName}.class);@Autowiredprivate $!{tableInfo.name}Service $!tool.firstLowerCase($tableInfo.name)Service;/*** 通过主键查询单条数据* @param id 主键* @return 单条数据*/@RequestMapping(value = "/selectOne")@ApiOperation(value = "通过主键查询单条数据")public $!{tableInfo.name} selectOne($!pk.shortType id) {return this.$!{tool.firstLowerCase($tableInfo.name)}Service.queryById(id);}
}

 6.6、mapper.xml

##引入mybatis支持
$!mybatisSupport##设置保存名称与保存位置
$!callback.setFileName($tool.append($!{tableInfo.name}, "Dao.xml"))
$!callback.setSavePath($tool.append($modulePath, "/src/main/resources/mapper"))##拿到主键，暂且认为第一个字段为id的话，作为主键
#if(!$tableInfo.fullColumn.isEmpty())#if($tableInfo.fullColumn.get(0).name == "id")#set($pk = $tableInfo.fullColumn.get(0))#end
#end<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="$!{tableInfo.savePackageName}.dao.$!{tableInfo.name}Dao"><resultMap type="$!{tableInfo.savePackageName}.entity.$!{tableInfo.name}" id="$!{tableInfo.name}Map">

#end</resultMap><!--查询单个--><select id="queryById" resultMap="$!{tableInfo.name}Map">select#allSqlColumn()from $!{tableInfo.obj.parent.name}.$!tableInfo.obj.namewhere $!pk.obj.name = #{$!pk.name}</select>
</mapper>

7、Global Config配置

 去掉表前缀设置
