如何使用 Java 漂亮地打印现有的 JSON 数据?

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，而不必先反序列化它——例如就像 jsonlint.org 一样.有没有提供这个的库?

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?

类似的 XML 解决方案也不错.

A similar solution for XML would also be nice.

推荐答案

我认为对于打印漂亮的东西，了解它的结构非常有帮助.

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

要获得结构，您必须 解析它.正因为如此，我认为这并不比首先解析您拥有的 JSON 字符串然后使用漂亮的打印方法容易得多 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，你可以对任何你喜欢的 JSON 库做类似的事情.

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