sonar质量检测 -- Fields in a "Serializable" class should either be transient or serializable

最近在使用sonar检查自己java代码的质量，也让我学习到了很多写法上的新东西，今天遇到了这样一个问题：

Fields in a "Serializable" class should either be transient or serializable

我的原代码这样的：这是个公共类，实现了序列化接口。     

@Data
public class PespResponse implements Serializable {

    private String message;

    private int code = ActionResultCode.SUCCESS.getValue();

    private T data;

    public PespResponse(){
        this.code = ActionResultCode.SUCCESS.getValue();
        this.message = "请求成功";
    }

    public PespResponse(int code,String msg){
        this();
        this.code = code;
        this.message = msg;
    }
    public PespResponse(int code,String msg,T data){
        this();
        this.code = code;
        this.message = msg;
        this.data = data;
    }
    public PespResponse(T data){
        this();
        this.data = data;
    }
}

但是在使用sonar质量分析的时候提示是：Fields in a "Serializable" class should either be transient or serializable  squid:S1948

 一时不知道怎么解决，查找了相关资料，于是有了下面这样的写法，特此做下笔记：

public class PespResponse implements Serializable {

    private String message;

    private int code = ActionResultCode.SUCCESS.getValue();

    private T data;

    public PespResponse(){
        this.code = ActionResultCode.SUCCESS.getValue();
        this.message = "请求成功";
    }
