我的Referer是：https://portaldecustas.tjsp.jus.br/portaltjsp/login.jsp
我的目标是： https://portaldecustas.tjsp.jus.br/portaltjsp/
我GET配置： [expectContinueEnabled =虚假，代理= NULL，将localAddress = NULL，cookieSpe c = null，redirectsEnabled = true，relativeRedirectsAllowed = true，maxRedirects = 50，circularRedirectsAllowed = false，authenticationEnabled = true，targetPreferredAuthSchemes = null，proxyPreferredAuthSchemes = null，connectionRequestTimeout = 1000，connectTimeout = 60000，socketTimeout = 60000，contentCompressionEnabled = true]
（我已搜查这个错误，但我没有找到一个soluction对于这种特殊情况下）
它是代码：
HttpGet get = newGetMethod(getTarget(), getTimeoutHandler());
HtmlNode htmlNode = requestHtml(get);
...当newGetMethod这是一个methos从我公司的框架：
/**
* Cria um get
*
* @param target Endere?o acessado
* @param timeoutHandler Controla o timeout
* @return Get
* @throws HarvestException Quando ocorre um erro com o tempo a ser usado
*/
public static HttpGet newGetMethod(URI target, TimeoutHandler timeoutHandler) throws HarvestException {
HttpGet method = newGetMethod(target, timeoutHandler.calculate());
method.getParams().setParameter(TIMEOUT_HANDLER_PARAM, timeoutHandler);
return method;
}
问题不清楚！ B类的定义是什么？你也可以把整个堆栈跟踪？ – nagendra547
是的，我发送整个堆栈跟踪... –
它与此类似：https：//stackoverflow.com/questions/14022602/java-lang-classcastexception-b-cannot-be-cast-to-java-lang-string 但在我的情况下，它有点不同...真的很难发现 –
