Java Web Service error: com.ctc.wstx.exc.WstxEOFException: prolog 中意外的 EOF
2022-09-03 01:28:04
我在创建 Java 客户端并将其连接到正在运行的 Web 服务时遇到问题。
我使用以下代码:
Service myService = null;
URL wsdlLocation = new URL("http://myservice?wsdl");
QName serviceName = new QName(wsdlLocation, "MyService");
Service myService = new Service(wsdlLocation, serviceName);
其中,服务类是使用以下命令创建的:
wsimport -d gen -keep http://myservice?wsdl
我也尝试过使用Apache cxf 2.4的wsdl2java生成的客户端,但得到了相同的结果。
(我只为这篇文章更改了WSDL位置和服务类名称,在代码中我使用原始代码。
但是,当我使用新的 Service() 命令创建服务时,调用应用程序服务器上部署的 Web 服务时,我会遇到异常。但是:我已经使用SOAP UI测试了wsdl位置,它工作得很好。另外,我使用 Soap UI 创建了一个 Mock Service,我的 Java 客户端可以连接到它,调用它并获取结果。当我想调用在应用程序服务器上运行的Web服务时,问题出现了。
