从Java7上的SpringWS客户端向Java6上的服务器发送SOAP消息时，左尖括号被删除

这对我来说真的很沮丧，所以我现在会尝试解释我知道什么和不知道什么。请确保在帖子底部看到我的更新

首先，我们有一个war，它使用SpringWS来处理消息。我们还有一个客户端，它使用WebServiceTemplate发送消息。我们部署在Tomcat7上

在我们当前的开发环境中，Tomcat7服务器使用JRE 6u24。在本地，当我使用客户端发送SOAP消息时，我正在运行相同的版本。一切正常

当我制作本地JRE 7u04时，得到500响应，服务器看到以下错误：

当我使用带有JRE 6的客户端发送时，createMessage调用后的inputStream开始如下：

[60, 101, 110, 118, 58, 69, 110, 118, 101, 108, 111, 112, 101, 32, 120, 109, 108, 110, 115, 58, 101, 110, 118, 61, 34, 104, 116

[101, 110, 118, 58, 69, 110, 118, 101, 108, 111, 112, 101, 32, 120, 109, 108, 110, 115, 58, 101, 110, 118, 61, 34, 104, 116

转换为：

也许checkForUtf8ByteOrderMark有一些副作用
方法

我想你可能是对的

升级到2.0.4.RELEASE以某种方式修复了此问题。checkForUtf8ByteOrderMark方法没有更改，但由于随后传入的流看起来有所不同，因此肯定有其他内容发生了更改。
您可以从openjdk项目中获取jdk的源代码。@jtahlborn我确实访问了此页面并在那里下载了源代码。但是，我没有找到任何这些内部类，所以可能那不是正确的位置？我确实设法在网上找到了许多这样的文件，所以我只是制作了自己的小源jar并将其与我的项目关联起来。不是很好，但是还可以。不是所有的源文件都在主下载中。这有点烦人。您可以运行附带的ant脚本来下载一些辅助包（jaxws、jaxb等）。我对正在使用的流有点困惑，它实际上就是我更新中的那个流（对不起）。所以，现在真正的问题不是缺少60字节，而是其中有两个0字节。不过，感谢您为我指出了一个好的方向。顺便问一下，您使用的是哪个Spring WS版本？我目前使用的是2.0.2.RELEASE。我知道2.0.5是最新版本，但我不确定是否/何时能升级。事实上，我越深入研究，我越觉得这确实是一个副作用，哈哈。我认为，我必须扩展该类或实现其接口，并尝试一些更改。这真的让我心烦意乱。是的，是的，是的！因为buf完成了它所做的工作，所以PushbackInputStream中有一段代码，首先添加缓冲区，然后读取字节。因此，它读入这三个字节，然后读取其余的字节。这确实是一个副作用！你把这篇文章贴在这里让我再次审视了这一连串的事件，这让我重新审视了它。我必须看看2.0.5是否有更好的版本。我们有同样的问题。“SpringWS2.0.2”Web服务通过http工作，但不能通过https工作。在SpringWS2.0.4上升级解决了我们的问题。谢谢
