如何在Java中验证字符串是否为JSON? [英] How to validate a string is JSON or not in Java?

问题描述

我已经说过，我的问题有所不同...问题已经被问过

I've already said, my question is different...question is already asked here, but i want a predefined method in java which checksgiven string is json format or not.

如果没有预定义的方法，则至少告诉一个代码是否检查JSON格式，而不使用try catch块.

if there is no predefined method then at least tell a code which checks JSON Format or not, without using try catch block..

预先感谢...

推荐答案

使用String中的 JSONObject的构造函数

Use JSONObject's constructor from a String

    try {
        JSONObject o = new JSONObject(yourString);
    } catch (JSONException e) {
        LOGGER.error("No valid json");
    }
