java - 发送无效的xml时如何修复websphere上的java堆空间

Question

当我向 websphere 服务器上的 web 服务发送无效的 xml 时，我得到了 java 堆空间:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/">
   <soap:Header/>
   <soap:Body>
       <MyElementsomething</MyElement>

   </soap:Body>
</soap:Envelope>

与元素

   <MyElement>something</MyElement>

一切正常

异常(exception):

编辑:

没人知道吗？

PS:spring validation 没有帮助，因为它是在 websphere 之后。当我再次向 xsd 发送无效的 xml(例如字符串而不是数字)时，它会起作用:

2015-02-18 10:12:46.128 [WebContainer : 8] WARN  cz.isvs.ais3.ws.interceptor.ServerPayloadValidatingInterceptor - XML validation error on request: cvc-datatype-valid.1.2.1: 'b' is not a valid value for 'integer'.
2015-02-18 10:12:46.128 [WebContainer : 8] WARN  cz.isvs.ais3.ws.interceptor.ServerPayloadValidatingInterceptor - XML validation error on request: cvc-type.3.1.3: The value 'b' of element 'urn1:Ais' is not valid.

因为WebServiceMessageReceiverObjectSupport.class:

86            WebServiceMessage request = connection.receive(getMessageFactory()); // here occurs out of memory
87            MessageContext messageContext = new DefaultMessageContext(request, getMessageFactory());
88            receiver.receive(messageContext); // and in this method are interceptor which validate request

PS2:

当我尝试将堆空间从 2gb 增加到 4gb 时，同一位置出现另一个异常:

java.lang.IndexOutOfBoundsException
        at java.io.PushbackInputStream.read(PushbackInputStream.java:181) ~[?:1.7.0]

这是 sun java 的正确行为:

Answer 1

这看起来像一个 Websphere 错误。使用 Spring-WS 我得到了一些错误:

java.lang.OutOfMemoryError: Java heap space at com.ibm.ws.webservices.utils.BAIS.create(BAIS.java:74)

我设法以这种方式解决:放入/AppServer/lib/ext 这个库:axis2-saaj-1.6.2.jar(在 Websphere v8.5 和 Spring-WS v2.2.0 上为我工作，但你可能必须更改版本)。

解释

当 Spring-WS 请求 javax.xml.soap.MessageFactory 实现时，它获得 com.ibm.ws.webservices.engine.soap.MessageFactoryImpl 实例(来自 Websphere 运行时)而不是 com.sun.xml.internal .messaging.saaj.soap.MessageFactoryImpl 实例(来自 JVM)，这会导致上述错误。axis2-saaj 库还包含一个 javax.xml.soap.MessageFactory 实现:org.apache.axis2.saaj.MessageFactoryImpl。当 axis2-saaj 在 lib/ext 文件夹中并且错误消失时，现在使用这个(我还配置了 PARENT LAST 类路径，不知道这里是否重要)

@hudi 你的解决方案是正确的，我刚刚测试过。遗憾的是，不能给你投票。
