1.Bmob云服务

Bmob云服务实现简易增删改查代码

Person.java

package com.example.bmobtest;import cn.bmob.v3.BmobObject;public class Person extends BmobObject{private String name;    private String address;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getAddress() {        return address;    }    public void setAddress(String address) {        this.address = address;    }@Overridepublic String toString() {return "Person [name=" + name + ", address=" + address + "]";}    }
