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 vopythonid 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
SCJKqqopring 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China编程图渲染的问题。
