统一返回JsonResult踩坑的记录

public class jsonresult<t> {

    private int code;
    private string message;
    private t data;

    public jsonresult() {}

    public jsonresult(int code, string message, t data) {
        this.code = code;
        this.message = message;
        this.data = data;
    }

    public int getcode() {
        return code;
    }

    public void setcode(int code) {
        this.code = code;
    }

    public string getmessage() {
        return message;
    }

    public void setmessage(string message) {
        this.message = message;
    }

    public t getdata() {
        return data;
    }

    public void setdata(t data) {
        this.data = data;
    }

    public static <t> jsonresult<t> success(t data) {
        return new jsonresult<>(200, "success", data);
    }
}
