我试图评估Spring Integration,特别是将基于简单POJO的服务通过服务激活器暴露为基于SOAP的Web服务。目前我遇到了问题,无法生成动态WSDL。WSDL未加载,浏览器显示404错误。我尝试在本地使用以下URL进行访问:
http://localhost:8080/ws-inbound-gateway/echoService
http://localhost:8080/ws-inbound-gateway/echoService/echoService.wsdl
以下是配置信息:
inbound-gateway-config.xml
<int:channel id="inbound" />
<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.manish.schema.generated" />
</bean>
<int-ws:inbound-gateway id="empServiceGateway"
request-channel="inbound" marshaller="marshaller"
unmarshaller="marshaller" />
<int:service-activator input-channel="inbound"
requires-reply="true" ref="employeeServiceActivator" method="getEmployeeDetails">
</int:service-activator>
<bean id="employeeServiceActivator"
class="org.springframework.integration.samples.ws.EmployeeServiceResponder" />
<bean id="employeeService" class="com.manish.service.EmployeeService" />
EmployeeService是一个普通的pojo类,而EmployeeServiceResponder是一个服务激活器,它调用服务类上的方法。
用于动态wsdl生成。
spring-ws-config.xml
<import resource="classpath:/META-INF/spring/integration/inbound-gateway-config.xml" />
<sws:dynamic-wsdl id="echoService" portTypeName="empServiceGateway" locationUri="/echoService" targetNamespace="http://manish.niyati.com/echo">
<sws:xsd location="/WEB-INF/echo.xsd"/>
</sws:dynamic-wsdl>
<bean
class="org.springframework.ws.server.endpoint.mapping.UriEndpointMapping">
<property name="defaultEndpoint" ref="empServiceGateway"></property>
</bean>
web.xml
<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-config.xml</param-value>
</init-param>
<init-param>
<param-name>transformWsdlLocations</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring-ws</servlet-name>
<url-pattern>/echoService</url-pattern>
</servlet-mapping>
请告诉我还缺少哪些内容,以便将此服务作为Web服务通过SI访问。
另外,当我尝试使用WebService模板访问该服务时,我收到了SOAPFAULT错误。
