Question

我有一个应用程序需要httpclient-4.2.5.jar库才能正确运行。我也想使用HtmlUnit库（版本2.12）。由于库冲突（在httpclient-4.2.5.jar和htmlunit-2.12.jar之间），它失败了（我认为）

这是我的日志输出，但是我没有太多地记录它对我说的内容，因为我没有在日志中调用任何这些方法......

Answer 1

这一切都很简单。 HtmlUnit通过反思在HttpClient代码中使用私有方法：

http://sourceforge.net/p/htmlunit/code/8377/tree/trunk/htmlunit/src/main/java/com/gargoylesoftware/htmlunit/HtmlUnitSSLSocketFactory.java#l113

版本4.2.4中删除了相关方法。见HTTPCLIENT-1320

Answer 2

嗯，对我有用的唯一解决方案是降级到httpclient 4.2 - http://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient/4.2

Answer 3

将htmlunit版本提升为2.15可以解决问题。为我工作

Answer 4

快速检查“org.apache.http.conn.ssl.SSLSocketFactory”类文档，那里没有这样的“createDefaultSSLContext（）”方法。

Answer 5

我有这个问题，因为我想在Selenium中使用WebClient。

我将Selenium从2.33.0升级到2.45.0，之后WebClient运行良好。

Java - .jar库方法有冲突吗？
