创建Apache Abdera客户端失败
我的代码的一部分是
Abdera abdera = new Abdera();
AbderaClient abderaClient = new AbderaClient(abdera);
这把我丢了...

任何帮助!
最佳答案
显然看起来像下面AbderaClient方法中的错误；使用反射来查找LRUCacheFactory的构造函数:
private CacheFactory initCacheFactory() {
CacheFactory cacheFactory =
(CacheFactory)Discover.locate(
CacheFactory.class.getName(),
LRUCacheFactory.class.getName(),
abdera);
return cacheFactory;
}
检查您的
LRUCacheFactory版本中是否存在任何此类构造函数。建议切换到最新的Abdera版本(1.1.3)。但是，我也在论坛中找到了解决方法。尝试是否正常。
AbderaClient client;
ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
try {
ClassLoader cl = this.getClass().getClassLoader();
Thread.currentThread().setContextClassLoader(cl);
Abdera abdera = new Abdera();
client = new AbderaClient(abdera);
// Do something with client
} finally {
// Restore original classloader
Thread.currentThread().setContextClassLoader(originalClassLoader);
}
