Thread.currentThread().getContextClassLoader().getResource

This code snippet returns a URL object representing the resource specified by the given name. The resource is searched for in the classpath of the current thread's context class loader.
For example, if you have a file named "sample.txt" in the "resources" directory of your project, you can load it using the following code:
```
URL resourceUrl = Thread.currentThread().getContextClassLoader().getResource("resources/sample.txt");
```
This will return a URL object representing the location of the "sample.txt" file. You can then use this URL to read the contents of the file or perform other operations on it.

Thread.currentThread().getContextClassLoader().getResource)
This code snippet returns a URL object representing a resource file that is located in the classpath of the current thread's context class loader.
The getResource() method is called on the context class loader of the current thread, which is responsible for loading classes and resources for that thread. The method takes a relative path to a resource file as its argument and returns a URL object that represents the location of the resource file in the classpath.
For example, if the resource file "myFile.txt" is located in the root directory of the classpath, you can obtain its URL as follows:
URL url = Thread.currentThread().getContextClassLoader().getResource("myFile.txt");
The returned URL can be used to read the contents of the resource file, or to pass as an argument to other methods that expect a URL representing a resource.
Thread.currentThread().getContextClassLoader().getResource("")为null
这可能是因为在当前线程的上下文类加载器中找不到资源的原因。可以尝试使用以下代码来获取资源:
```
ClassLoader classLoader = getClass().getClassLoader();
URL resource = classLoader.getResource("");
```
这个代码片段中获取的是当前类的类加载器。如果你在其他类中使用这段代码,记得将getClass()替换为你自己的类。另外,如果你需要获取的是某个特定文件的URL,可以在getResource()方法的参数中指定文件名。
