如何用Java打印现有的JSON数据？ [英] How do I pretty-print existing JSON data with Java?

问题描述

我有一个紧凑的JSON字符串，我想在Java中很好地格式化它，而不必首先反序列化它 - 就像 jsonlint.org 一样。是否有任何图书馆提供这个？

I have a compact JSON string, and I want to format it nicely in Java without having to deserialize it first -- e.g. just like jsonlint.org does it. Are there any libraries out there that provides this?

一个类似的XML解决方案也会很好。

A similar solution for XML would also be nice.

推荐答案

我认为打印漂亮的东西，知道它的结构是非常有帮助的。

I think for pretty-printing something, it's very helpful to know its structure.

要获得结构，必须解析它。正因为如此，我不认为它比首先解析你的JSON字符串，然后使用漂亮的打印方法 toString 在上面的评论中提到。

To get the structure you have to parse it. Because of this, I don't think it gets much easier than first parsing the JSON string you have and then using the pretty-printing method toString mentioned in the comments above.

当然，你可以做任何类似的任何JSON库你喜欢。

Of course you can do similar with any JSON library you like.
