高复用服务响应对象实现

    最近在整理自己做过的项目，项目采用前后端完全分离的方式进行开发，使用json进行前后端数据传输，后端针对接口进行编写。项目使用了高复用服务响应对象设计，自我感觉大大提高了开发的效率和代码的复用率，故在此做记录。

//保证序列化的时候，如果为null，key也会消失
@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)
public class ServerResponse<T> implements Serializable{

    private int status;
    private String msg;
    private T data;

    private ServerResponse(int status){
        this.status = status;
    }
    private ServerResponse(int status, String msg){
        this.status = status;
        this.msg = msg;
    }
    private ServerResponse(int status, T data){
        this.status = status;
        this.data = data;
    }
    private ServerResponse(int status, String msg, T data){
        this.status = status;
        this.msg = msg;
        this.data = data;
    }

    //使之不在json序列化结果当中
    @JsonIgnore
    public boolean isSuccess(){
        return this.status == ResponseCode.SUCCESS.getCode();
    }

    public int getStatus(){
        return status;
    }
    public T getData(){
        return data;
    }
    public String getMsg(){
        return msg;
    }

    public static <T> ServerResponse<T> createBySuccess(){
        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode());
    }
    public static <T> ServerResponse<T> createBySuccessMassage(String msg){
        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(), msg);

        return new ServerResponse<T>(ResponseCode.SUCCESS.getCode(), msg, data);

    }
    public static <T> ServerResponse<T> createByErrorCodeMessage(int errorcode, String msg){
        return new ServerResponse<T>(errorcode, msg);
    }
}
