lombok @Accessors chained objects

@Accessors(chain=true)

For chained access, this annotation sets chain=true and generates a setter method that returns this ( that is, the object is returned ) instead of the default return void.

package com.pollyduan;

import lombok.Data;
import lombok.experimental.Accessors;

@Data
@Accessors(chain=true)
public class User {
    private Integer id;
    private String name;
    private Integer age;

    public static void main(String[] args) {
        //开起chain=true后可以使用链式的set
        User user=new User().setAge(31).setName("pollyduan");//返回对象
        System.out.println(user);
    }

}

@Accessors(fluent = true)

Similar to chain=true, the difference is that getter and setter do not have set and get prefixes.

package com.pollyduan;

import lombok.Data;
import lombok.experimental.Accessors;

@Data
@Accessors(fluent=true)
public class User {
    private Integer id;
    private String name;
    private Integer age;

    public static void main(String[] args) {
        //fluent=true开启后默认chain=true，故这里也可以使用链式set
        User user=new User().age(31).name("pollyduan");//不需要写set
        System.out.println(user);
    }

}

@Accessors(prefix = "f")

The set method ignores the specified prefix. I don’t recommend the great gods to name it like this.

package com.pollyduan;

import lombok.Data;
import lombok.experimental.Accessors;

@Data
@Accessors(prefix = "f")
public class User {
    private String fName = "Hello, World!";

    public static void main(String[] args) {
        User user=new User();
        user.setName("pollyduan");//注意方法名
        System.out.println(user);
    }

}
