Spring WS DefaultWsdl11Definition 错误

Question

我正在使用 Spring WS 并声明 DefaultWsdl11Definition bean 来动态生成 W​​SDL 文件。

但是，当我启动网络服务器（tomcat）时，我收到一个 bean 实例化错误，原因是：

    Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: javax/wsdl/extensions/ExtensibilityElement

SpringWS-Servlet.xml 中的 Bean

<bean id="beanWS" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
        <property name="schema">
            <bean class="org.springframework.xml.xsd.SimpleXsdSchema">
                <property name="xsd" value="/WEB-INF/somexsd.xsd"/>
            </bean>
        </property>
        <property name="portTypeName" value="beanWS"/>
        <property name="locationUri"
                  value="http://localhost:8080/springws"/>
    </bean>

任何想法可能是什么问题..

PS：Spring 版本是 3.0.5 ，Spring WS 版本是 2.0.0-M3

谢谢

Answer 1

Spring-WS 依赖于 WSDL4J 库，您似乎缺少该库。

Answer 2

我遇到了同样的错误。然后我意识到缺少 wsdl4j 依赖项。

<dependency>
    <groupId>wsdl4j</groupId>
    <artifactId>wsdl4j</artifactId>
</dependency>

如果您升级 Spring-ws 版本，您可以使用下面的 pom.xml

<properties>
    <spring.version>4.2.5.RELEASE</spring.version>
    <spring.ws.version>2.2.4.RELEASE</spring.ws.version>
    <log4j.version>1.2.16</log4j.version>

Answer 4

您需要包含 WSDL 库。 Spring WS Core 2.0.0-M1 的 POM 包含此参考：

http://mvnrepository.com/artifact/org.springframework.ws/spring-ws-core/2.0.0-M1
