我是Spring的新手，从一开始就开始自学，因为我想开发基于Spring-WS的Web服务。
我在schemas.xsd, spring-ws-servlet.xml文件夹中创建了web.xml和WEB-INF个文件。
还实现了使用@Endpoint注释的端点。
在我的scehmas.xsd我有以下元素
<xsd:element name="SimpleRequest">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="reName" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
并在web.xml中指定spring-ws消息调度程序servlet，如下所示。
<servlet>
<servlet-name>spring-ws</servlet-name>
<servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-ws-servlet.xml</param-value>
</init-param>
<init-param>
<param-name>transformWsdlLocations</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>spring-ws</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
在spring-ws-servlet.xml中我定义了端点
<context:component-scan base-package="com.test" />
<sws:annotation-driven />
<sws:dynamic-wsdl id="form" portTypeName="GUIForm"
locationUri="/forms/">
<sws:xsd location="/WEB-INF/schemas.xsd" />
</sws:dynamic-wsdl>
<bean id="formsEndpoint" class="com.test.FormsEndpoint" />
<bean
class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping">
<property name="defaultEndpoint" ref="formsEndpoint" />
</bean>
在我的FormsEndpoint课程中，我有以下方法，
@PayloadRoot(namespace = NAMESPACE_URI, localPart = "SimpleRequest")
@ResponsePayload
public Element handleFormsRequest(@RequestPayload Element simpleRequest) throws JDOMException, ParserConfigurationException
{
System.out.println("================ Hit on Endpoint ========================");
String formId = formIdExpression.valueOf(simpleRequest);
}
在formIdExpression.valueOf(simpleRequest);行，它总是抛出

我在eclipse中使用soapUI插件测试了一个请求。关于为什么发生这种情况的任何想法都将受到高度赞赏。

您必须首先生成与“SimpleRequest”对应的类。您可以使用JAXB。
然后，
public Element handleFormsRequest(@RequestPayload Element simpleRequest)
应该是
public Element handleFormsRequest(@RequestPayload **clazz** simpleRequest)
其中clazz是生成的类

当我开始使用Jdom而非Jdom2问题得到解决时，Jdom出现问题。
