Understanding Thread.currentThread().getContextClassLoader().getResourceAsStream()
提问by Tony
I am looking at a code example, and I am not sure what this means.
我正在查看代码示例，但不确定这意味着什么。
Thread.currentThread().getContextClassLoader()
.getResourceAsStream("MyProperty.properties");
It appears that it looking to read a property file but I am not sure where MyProperty.properties is located.
看起来它想读取一个属性文件，但我不确定 MyProperty.properties 所在的位置。
I appreciate for any help, thanks.
我感谢任何帮助，谢谢。

MyProperty.properties。
As you currently have it there, that will look for the MyProperty.propertiesfile at the top of your classpath. The could be in your src/main/resourcesdirectory or other src folder -- it would depend on how your application (jar/war) is built.
正如您目前拥有的那样，它将MyProperty.properties在您的类路径顶部查找文件。可能在您的src/main/resources目录或其他 src 文件夹中——这取决于您的应用程序 (jar/war) 的构建方式。
If you are building a jar then you should be able to unpack it and see your properties file at the top level of the jar. If you are building a war, maybe it should be in the WEB-INF/classesdirectory. Again, it depends on how it was built.
如果您正在构建一个 jar，那么您应该能够解压缩它并在 jar 的顶层查看您的属性文件。如果您正在构建War，也许它应该在WEB-INF/classes目录中。同样，这取决于它是如何构建的。
Typically the log4j.propertiesfile is also at the top of the classpath so you may want to look for that file and put your property file alongside it.
通常该log4j.properties文件也位于类路径的顶部，因此您可能需要查找该文件并将您的属性文件放在它旁边。
