最近我开始听说"POJO"(Plain Old Java Objects).我用Google搜索,但仍然不理解这个概念.任何人都可以给我一个明确的POJO描述吗？

考虑具有变量"id,name,address,salary"的类"Person" - 我将如何为此场景创建POJO？代码是否低于POJO？

public class Person {
    //variables
    People people = new People();
    private int id;
    private String name;
    private String address;
    private int salary;


    public int getId() {
        return id;
    }

    public String getName() {
        return name;
    }

    public String getAddress() {
        return address;
    }

    public int getSalary() {
        return salary;
    }

    public void setId() {
        this.id = id;
    }

    public void setName() {
        this.name = name;
    }

    public void setAddress() {
        this.address = address; …
