[JAVA Spring SOAP WSDL]

Question

我尝试使用 spring/soap/wsdl 连接到 Web 服务。我收到这样的堆栈跟踪：

Exception in thread "main" org.springframework.ws.soap.SoapMessageCreationException: Could not create message from InputStream: Unable to create envelope from given source: ; nested exception is com.sun.xml.internal.messaging.saaj.SOAPExceptionImpl: Unable to create envelope from given source:

我已使用本教程：https://spring.io/guides/gs/consuming-web-service/#initial 来了解自己。

我发现一些信息表明我的命名空间有问题？

ps。对不起我的英语

Answer 1

我遇到了同样的问题，原因是这样的：

WebServiceTemplate template = new WebServiceTemplate(messageFactory());
...    
template.setDefaultUri("http://host:2121/portal/service?wsdl");

解决方案是删除?wsdl

Answer 2

我遇到了同样的问题。我不知道究竟是什么在您的来源中导致了这种情况，因为您没有添加任何特定信息，但我可以告诉它，当我将 fop 添加到我的 pom 时，它开始在我的项目中出现此错误：

    <dependency>
        <groupId>org.apache.xmlgraphics</groupId>
        <artifactId>fop</artifactId>
        <version>1.1</version>
        <!-- some exclusions needed because of inexistent "avalon" packages in maven repositories -->
    </dependency>

我可以通过 maven 找到的每个版本的 fop 都发生了这种情况。

我找到了solution here。显然，fop 中包含的 xalan 和 xerces 需要升级。

我对这个解决方案不满意，但它确实有效。我留下了一些我不确定是否需要或可能会损坏其他东西的排除项，因为截止日期很快就会到来（哈哈哈）。我稍后再讨论（或希望其他人可以评论他们）。

我在这里添加我的 pom 片段：

    <dependency>
        <groupId>org.apache.xmlgraphics</groupId>
        <artifactId>fop</artifactId>
        <version>1.1</version>
        <exclusions>
            <!--

                as dependencies for fop 1.1 are not found 
                through maven:
