java - 为什么这个解码器会抛出 MalformedURLException？

Question

• 网络逻辑 11g (10.3.5)
• Spring 框架 3.1.3
• Spring 网络服务 2.1.1

在 Weblogic 上运行的 Spring-ws Web 服务。相同的 Web 服务在 Tomcat 和 Spring vFabric 中运行良好，但在 Weblogic 下会抛出这些神秘的异常。 Weblogic 上从未达到我的实现代码，而是请求处理在解码期间的某个时刻中断。我试图通过这个问题进行调试，但有两个因素使问题复杂化。首先，解码器来自 Weblogic，这意味着我没有源代码。其次，主要异常来自 java.net.URL，Eclipse 调试器似乎无法检查局部变量值。

这是堆栈跟踪，跟踪级别的日志指向它。

问题是 WLS 10.3.5 附带了它自己的 Spring 版本 2.5.6.SEC01。所以默认情况下，WLS 始终使用该版本，因为它是由更高级别的类加载器加载的。这可能会导致您看到 UnmarshalException。

你的spring库是在WebLogic Application APP-INF/lib 还是你的web application WEB-INF/lib？如果spring 3.1.3是在application级别，你需要创建一个weblogic-application.xml，入口如下

<?xml version="1.0" encoding="UTF-8"?>
<weblogic-application>
    <prefer-application-packages>
        <package-name>org.apache.*</package-name>
        <package-name>org.springframework.*</package-name>
    </prefer-application-packages>
</weblogic-application>

如果是web应用层，在weblogic.xml中添加如下条目

<prefer-web-inf-classes>true<prefer-web-inf-classes>
