Origin of need:

In the previous two chapters, I introduced lombok and how to install Lombok in Eclipse under indow . Since I use a Mac computer at work and the development tool is an idea , this article introduces the installation and use of the idea on a Mac computer .

Imprint

(1) spring boot: 1.5.8;
(2) lombok: 1.16.20;
(3) OS: Mac
(4) Development tools: idea ultimate 2017.2

1. Introduction to Lombok

Lombok has been introduced in the previous two articles, so I won't state it too much here.

2. Installation of Lombok under idea

It is very simple to install lombok under the idea , and it can be done in the idea tool. The specific operations are as follows (note the version of the idea , the version is different, and the menu item names are different):

【打开idea软件】--在左上角的菜单【IntelLIJ IDEA】--【Preferences…】--【Plugins】--点击【Browse repositories…】--【在左上角搜索输入lombok】--【选中Lombok Plugin】--【在右边点击Install】，接下来根据提示进行操作就可以了。

三、Lombok在idea下的使用

3.1 新增依赖

在项目的pom.xml文件中新增lombok的依赖：

<dependency> 
         <groupId>org.projectlombok</groupId> 
         <artifactId>lombok</artifactId> 
         <scope>provided</ scope> 
</dependency>

也可以指定版本号： <version>1.16.20</version>

3.2 新增一个Girl实体类

（1）未使用Lombok的代码

public class Girl {
       private int id;//主键.
       private String name;//姓名.
       private int age;//年龄，女孩的年龄怎么能随便告诉你呢!
       private double weight;//体重. 这个问女孩，女孩会￣へ￣的.
       public int getId() {
              return id;
       }
       public void setId(int id) {
              this.id = id;
       }
       public String getName() {
              return name;
       }
       public void setName(String name) {
              this.name = name;
       }
       public int getAge() {
              returnage;
       }
       public void setAge(int age) {
              this.age = age;
       }
       public double getWeight() {
              return weight;
       }
       public void setWeight(double weight) {
              this.weight = weight;
       }
}

在之前的代码中需要手动生成getter and setter代码。

（2）使用Lombok的代码

import lombok.Data;
 
@Data
public class Girl {
       private int id;//主键.
       private String name;//姓名.
       private int age;//年龄，女孩的年龄怎么能随便告诉你呢!
       private double weight;//体重. 这个问女孩，女孩会￣へ￣的.
}

这是什么鬼，好干净好简单哦，这就是Lombok带给我们的。这里在也看不到长长的getter and setter方法了。

3.3 Girl调用

那么使用Lombok之后的属性是否能被getter和setter呢？好想看看那个女孩的体重哦（你想看的不是体重吧，老实说是不是Cup Size），看下调用的代码：

Girl girl = new Girl();
girl.setId(1);
girl.setName("Angelababy");
girl.setAge(29);
girl.setWeight(45);//单位：千克
System.out.println("姓名："+girl.getName()+"，年龄："+girl.getAge()+"，体重："+girl.getWeight());

可以获取到，这样使用Lombok之后，就会使得代码变得清爽很多。对于Lombok到这里就结束了，但是Lombok的还需要大家自己去挖掘，这艰巨的任务还是留给你们吧，我还是去new girl()。
