Lombok

网上优缺点：

优点缺点能通过注解的形式自动生成构造器、getter/setter、equals、hashcode、toString等方法，提高了一定的开发效率JDK版本升级（但我司的可能性不大）让代码变得简洁，不用过多的去关注相应的方法降低代码可读性（巨型构造器的存在）属性做修改时，也简化了维护为这些属性所生成的getter/setter方法等不支持多种参数构造器的重载

public class Student{
    private Long id;
    private String name;
    private int age;
    private int gender;
 
    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 int getAge(){
        return age;
    }
    public void setAge(int age){
        this.age = age;
    }
    public int getGender(){
        return gender;
    }
    public void setGender(int gender){
        this.gender = gender;
    }
 
    @Override
    public boolean equals(Object o){
        if(this == o){
            return true;
        }
        if(o == null || getClass() != o.getClass()){
            return false;
        }
        Student obj =  (Student) o;
        return age = obj.age &&
            gender = obj.gender &&
            Objects.equals(id,obj.id) &&
            Objects.queals(name,obj.name);
    }
 
    @Override
    public int hashCode(){
        return Objects.hash(id,name,age,gender);
    }
 
    @Override
    public String toString(){
        return "Student{"+
            "id="+id+
            "name="+name+
            "age="+age+
            "gender="+gander+
            "}";
    }
}

使用注解后

@Data
@Builder
public class Student{
    private Long id;
    private String name;
    private int age;
    private int gender;

}

Lombok注解

 

但其实就我们项目而言，个人建议

@Data

@AllArgsConstructor

@NoArgsConstructor

@Builder

@NonNull
