Properties files are as per specification read using ISO-8859-1. 属性文件根据ISO-8859-1读取的规范 。
... the input/output stream is encoded in ISO 8859-1 character encoding.
So, any character which is not covered by the ISO-8859-1 range needs to be escaped in the Unicode escape sequences \\uXXXX . 因此，任何未被ISO-8859-1范围覆盖的字符都需要在Unicode转义序列 \\uXXXX进行转义。 You can use the JDK-supplied native2ascii tool to convert them. 您可以使用JDK提供的native2ascii工具进行转换。 You can find it in JDK's /bin folder. 您可以在JDK的/bin文件夹中找到它。
Here's an example assuming that foo_utf8.properties is the one which you saved using UTF-8 and that foo.properties is the one which you'd like to use in your application: 这是一个例子，假设foo_utf8.properties是你使用UTF-8保存的那个，而foo.properties是你想在你的应用程序中使用的那个：
native2ascii –encoding UTF-8 foo_utf8.properties foo.properties
In your particular case, the property in question would then be converted to: 在您的特定情况下，相关财产将转换为：
login = \u041B\u043E\u0433\u0438\u043D
This can then be successfully read and displayed in a JSP page with the below minimum @page configuration: 然后可以成功读取并显示在具有以下最小@page配置的JSP页面中：
<%@ page pageEncoding="UTF-8" %>
(the remainder you had is irrelevant as those are the defaults already when above is set) （你所拥有的余数是无关紧要的，因为这些是上面设置时的默认值）
If you're using a Java-aware IDE such as Eclipse, then you can just use its builtin properties file editor which should automatically be associated with .properties files in a Java-faceted project. 如果您使用的是Java感知IDE（如Eclipse），那么您可以使用其内置属性文件编辑器，该编辑器应自动与Java面向项目中的.properties文件相关联。 If you use this editor instead of the plain text editor / source editor, then it'll automatically escape the characters which are not covered by the ISO-8859-1 range. 如果您使用此编辑器而不是纯文本编辑器/源编辑器，那么它将自动转义ISO-8859-1范围未涵盖的字符。

Since Java SE properties files are loaded in UTF-8 encoding. 由于Java SE属性文件以UTF-8编码加载。
