Question

这些天我将DWR引入我的项目中。我的项目是使用Spring 4，我试图通过使用注释approch将DWR与Spring集成。以下是我的集成工作代码。当我在Tomcat服务器上执行项目时出现如下所示的错误。

错误：

java.lang.NoSuchMethodError: org.springframework.util.ClassUtils.forName(Ljava/lang/String;)Ljava/lang/Class;
at org.directwebremoting.spring.DwrAnnotationPostProcessor.getBeanDefinitionClass(DwrAnnotationPostProcessor.java:96)

at org.springframework.context.support.AbstractApplicationContext.invokeBeanFactoryPostProcessors(AbstractApplicationContext.java:609)

的web.xml

<servlet>
  <servlet-name>dwr-dispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>2</load-on-startup>
</servlet>

DWR-调度-servlet.xml中

</bean>

</beans>

我还没有找到任何解决方案。然后我尝试使用Spring 3.2，启动成功，没有任何错误。我不确定Spring 4遇到DWR3时是否存在问题。任何身体都能帮忙吗？谢谢〜

Answer 1

在Spring 4中，forName中没有方法ClassUtils只接受String作为参数。正如您在JavaDoc here中看到的那样，该方法已在Spring 3中弃用

似乎DWR尚未升级其代码库以支持Spring 4.看起来你必须等待这种情况发生（尽管该项目似乎不活跃所以我不会这样做依靠很快发生的事情。）

当我使用带有Spring的DWR3.0 RC2启动项目时发生错误
