本文整理了Java中java.net.URLConnection.setDefaultUseCaches()方法的一些代码示例，展示了URLConnection.setDefaultUseCaches()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。URLConnection.setDefaultUseCaches()方法的具体详情如下：
包路径：java.net.URLConnection
类名称：URLConnection
方法名：setDefaultUseCaches

URLConnection.setDefaultUseCaches介绍

[英]Sets the default value for the flag indicating whether this connection allows to use caches. Existing URLConnections are unaffected.
[中]设置标志的默认值，该标志指示此连接是否允许使用缓存。现有的URL连接不受影响。

  1. @Override
  2. public void setDefaultUseCaches(boolean defaultusecaches) {
  3.   jarFileURLConnection.setDefaultUseCaches(defaultusecaches);
  4. }

  14.   
  15.   if (log.isDebugEnabled()) {
  16.     log.debug("Creating new OpenmrsClassLoader instance with parent: {}", parent);
  17.   }
  18.   
  19.   //disable caching so the jars aren't locked
  20.   //if performance is effected, this can be disabled in favor of
  21.   //copying all opened jars to a temp location
  22.   //(ala org.apache.catalina.loader.WebappClassLoader antijarlocking)
  23.   URLConnection urlConnection = new OpenmrsURLConnection();
  24.   urlConnection.setDefaultUseCaches(false);
  25. }
