Question

我有一个从wsdl创建的Web服务，并没有更改任何内容，所以我只有一个空的应用程序。

部署应用后，只要我点击“停止”即可。（即我甚至没有打电话给它），我得到了严重的＆＃39;来自Tomcat的消息和泄漏测试报告我的应用程序有多个实例，并且每次停止/启动时都会增加。

我正在使用CXF 3.1.0，甚至尝试下载最新的JAXB（网站上的参考实现）。

错误如下：

    cWorkQueueImpl.java:353)

Answer 1

这似乎是known limitation of the JAXB API。问题声明你可以通过明确关闭Unmarshaller来避免这个问题，但我自己没有尝试过。
