本文整理了Java中java.net.URL.getPath()方法的一些代码示例，展示了URL.getPath()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。URL.getPath()方法的具体详情如下：
包路径：java.net.URL
类名称：URL
方法名：getPath

URL.getPath介绍

[英]Returns the path part of this URL.
[中]返回此URL的路径部分。

代码示例

代码示例来源：origin: spring-projects/spring-framework

/**
 * Determine whether the given URL points to a jar file itself,
 * that is, has protocol "file" and ends with the ".jar" extension.
 * @param url the URL to check
 * @return whether the URL has been identified as a JAR file URL
 * @since 4.1
 */
public static boolean isJarFileURL(URL url) {
  return (URL_PROTOCOL_FILE.equals(url.getProtocol()) &&
      url.getPath().toLowerCase().endsWith(JAR_FILE_EXTENSION));
}

@VisibleForTesting

  } catch (URISyntaxException e) { // URL.toURI() doesn't escape chars.
   return new File(url.getPath()); // Accepts non-escaped chars like space.
  }
 }
}
