如何修复 ApplicationResources_fr.properties 损坏
How to fix ApplicationResources_fr.properties getting corrupted
我写的 class 有问题。 class 的目的是 add/remove/update applicationResource.properties 文件，<spring:message code="key" /> 使用这些文件为网站提供双语支持。手动与属性文件交互工作正常，但我有更大的需求，所以我构建了一种允许从数据库进行更改的方法。这给了我一个非常动态和灵活的系统，我可以从中工作。
但是，有一个问题。在某个时候，即使使用它进行一次更改后，法语字符也会发生变化。比如Déconnexion变成Déconnexion。在 notepad++ 中查看时，它的第一个 Déconnexion 然后损坏为 D\u00C3\u00A9connexion。此示例是原始属性文件的一部分。
原始（非临时）属性文件将 text file encoding 设置为 other: UTF-8。项目属性 text file encoding 设置为 inherited from container (Cp1252)。我尝试更改为 Other: UTF-8，但没有任何更改。
所以我的问题是，是什么导致我的法语字符损坏，我该如何解决？ 我在下面提供了完整的 class .
更新： 在 StephaneM 的回答中提供帮助后，我能够准确找到导致损坏的原因，但尚未修复。 AR Class 中的 loadProperties() 函数。一旦加载了临时 AP 文件，法语字符就会损坏。这让我怀疑创建临时 AP 文件的原始过程使用了不同的编码。所以我将不得不追踪它。

关于这个问题："what is causing the corruption to my French characters and how can I fix it?"，答案在文档中（Properties.store()）：
public void store(OutputStream out,
String comments)
throws IOException
Writes this property list (key and element pairs) in this Properties
table to the output stream in a format suitable for loading into a
Properties table using the load(InputStream) method.
Properties from the defaults table of this Properties table (if any)
are not written out by this method.
This method outputs the comments, properties keys and values in the
same format as specified in store(Writer), with the following
differences:
- The stream is written using the ISO 8859-1 character encoding.
- Characters not in Latin-1 in the comments are written as \uxxxx for their appropriate unicode hexadecimal value xxxx.
- Characters less than \u0020 and characters greater than \u007E in property keys or values are written as \uxxxx for the appropriate hexadecimal value xxxx.
