寻找标准库或技术来获得漂亮的Java OBJECT表示形式 [英] Look for standard library or technique to get pretty-printed representation of OBJECT for Java

问题描述

为了理解某些代码的内部结构或因错误而打印转储，我在pp 的函数 rel = nofollow noreferrer> Python 和Emacs lisp。

In order to understand internals of some code or print dumps on errors I use pp-like functions in Python and Emacs lisp.

现在，我来到Java，寻找标准库或tecnique以获得漂亮的印刷品

Now I come to to Java and look for standard library or tecnique to get pretty-printed representation of OBJECT for Java.

似乎当前的Java规范允许在运行时对Java对象进行自省。但是内省可能没有那么强大。 m（对象o）不能用新对象[] arg调用吗？

Seems that current Java specification allow introspection of Java object at runtime. But introspection may be not so powerful. m(Object o) can not be called with new Object [] arg?

注意我不正在寻找美化源代码！我正在寻找运行时漂亮的打印Java对象转储。

NOTE I am NOT looking to source code beautifier! I am looking for runtime pretty print Java object dumping.

NOTE2 这些问题相似但不完全相同：

• Java转储对象

• What's the simplest way to print a Java array?
• Best pretty-printing library for Java?
• Java dump an object

推荐答案

您可以使用 Apache Commons Lang 库中的ReflectionToStringBuilder 。

You could use the ReflectionToStringBuilder from the Apache Commons Lang library.

示例：

String dump = ReflectionToStringBuilder.toString(object);

关于您的问题：

m（Object o）不能用新对象[] arg调用吗？

m(Object o) can not be called with new Object [] arg?

当然可以，数组对象的子类型是对象的子类型。

Sure it can, arrays of Object is a subtype of Object.
