通过fastjson将一个对象序列化为json，同时加入指定的序列化逻辑

主函数:

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.serializer.ValueFilter;
import com.google.common.base.Preconditions;

public class xiaomi {
    public static void main(String[] args) {
        A a = new A();
        String json =ok.object2Json(a);
        System.out.println(json);
    }
}

实体类：

class A{
    int a;
    int b=1;
    String des ="wuhan";
    String dep ="xiantao";
    public String getDes() {
        return des;
    }
    public void setDes(String des) {
        this.des = des;
    }
    public String getDep() {
        return dep;
    }
    public void setDep(String dep) {
        this.dep = dep;
    }
    public int getA() {
        return a;
    }
    public void setA(int a) {
        this.a = a;
    }
    public int getB() {
        return b;
    }
    public void setB(int b) {
        this.b = b;
    }
}
