解析 WSDL 失败

Question

我正在尝试使用以下教程从 wsdl 生成 src，但在 wsimport 时出现异常。

http://www.mkyong.com/webservices/jax-ws/jax-ws-wsgen-tool-example/

wsimport -keep -verbose http://localhost:7001/poc-war/ServerInfoService?wsdl

出现以下错误：

C:\Program Files\Java\jdk1.8.0_102\bin>wsimport -keep -verbose http://localhost:7001/poc-war/ServerInfoService?wsdl
parsing WSDL...


[ERROR] Server returned HTTP response code: 504 for URL: http://localhost:7001/poc-war/ServerInfoService?wsdl

Failed to read the WSDL document: http://localhost:7001/poc-war/ServerInfoService?wsdl, because 1) could not find the document; /2) the document could not be read; 3) the root element of the document is not <wsdl:definitions>.


[ERROR] Could not find wsdl:service in the provided WSDL(s):

 At least one WSDL with at least one service definition needs to be provided.

Answer 1

这是网络问题。您可以在浏览器中打开 wsdl，将文本复制并粘贴到新的 .wsdl 文件中，然后从硬盘 URL 与网络 URL.

重新生成它

我曾有过网络安全问题使我无法使用某些开发工具访问 WSDL 的情况，因此在本地保留一个副本可以奏效。我承认这充其量只是一种解决方法，但如果没有更多信息，502 问题就不容易解决。
