People.java实体类：

package com.cy.entity;


public class People {

    private String name;
    private int age;
    private String className;
    
    
    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() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getClassName() {
        return className;
    }
    public void setClassName(String className) {
        this.className = className;
    }
    
    
    @Override
    public String toString() {
        return "People [> age
                + ", className=" + className + "]";
    }
