- 好处：有了lombok，就免去了实体类写get/set等通用方法的麻烦
- 缺点：降低了代码的可读性

- 示例：
之前：
package com.binge.entity;
import java.io.Serializable;
import java.util.List;
public class User implements Serializable{
private static final long serialVersionUID = 707985171749658644L;
private Long id;
private String name;
private List<String> friends;
public User() {
}
public User(Long id, String name, List<String> friends) {
this.id = id;
this.name = name;
this.friends = friends;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<String> getFriends() {
return friends;
}
public void setFriends(List<String> friends) {
this.friends = friends;
}
}
现在：
- jar包依赖
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.10</version>
<scope>provided</scope> <!--声明周期为编译，打包的时候jar包不会打入目标包中-->
</dependency>
- 实体类
