Spring Web服务抛出com.sun.xml.internal.messaging.saaj.soap.ver1_

Question

我对Spring完全陌生，从一开始我就开始自学，因为我想开发基于Spring- ws的web服务。我已经在WEB-INF文件夹下创建了schemas.xsd, spring-ws-servlet.xml和web.xml文件。还实现了用@Endpoint注释的端点。在我的scehmas.xsd中，我有下面的元素

<xsd:element name="SimpleRequest">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="reName" type="xsd:string" />                       
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>

和web.xml中，我指定了spring-ws消息分派器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类中，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);行总是抛出

我已经测试了一个请求使用soapUI插件在eclipse。

Answer 1

必须首先生成与"SimpleRequest"相对应的类。您可以使用JAXB。

,

public Element handleFormsRequest(@RequestPayload Element simpleRequest) 

应该

public Element handleFormsRequest(@RequestPayload **clazz** simpleRequest)

其中，clazz是生成的类

Answer 2

当我开始使用Jdom2而不是Jdom问题得到解决时，这是Jdom的问题。
