我要评论统一返回jsonresult踩坑
定义了一个统一返回类
但是没有给@data 导致没有get/set方法，请求一直报错
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);
}
}
在使用时，jsonresult没有get/set方法时
spring mvc 在序列化时无法将对象正确转换为 json，因此会被视为 视图名称，导致循环视图渲染的问题。

总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
