dwr3与spring mvc的整合。

Question

在进行spring mvc 和dwr的整合中：

web.xml的配置为：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns="http://java.sun.com/xml/ns/javaee"
 xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

  </listener-class>

 <servlet-mapping>
  <servlet-name>sample</servlet-name>
  <url-pattern>/dwr/*</url-pattern>
 </servlet-mapping>

 

 <filter>

 </filter>

 <filter-mapping>
  <filter-name>Spring character encoding filter</filter-name>
  <url-pattern>/*</url-pattern>
 </filter-mapping>

</web-app>

 

对应的spring的配置文件为：

<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:dwr="http://www.directwebremoting.org/schema/spring-dwr"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
    http://www.directwebremoting.org/schema/spring-dwr
    http://www.directwebremoting.org/schema/spring-dwr-3.0.xsd">

 <dwr:configuration></dwr:configuration>

 <dwr:controller id="dwrController" debug="true" />

 <bean id="dwrUrlMapping" name="dwrUrlMapping"
  class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="alwaysUseFullPath" value="true" />
  <property name="mappings">
   <props>
    <prop key="/dwr/*">dwrController</prop>
    <prop key="/dwr/**/*">dwrController</prop>
   </props>
  </property>
 </bean>

</beans>

 

启动tomcat 就报错了。

 

 

 

Answer 1

dwr:configuration/dwr:configuration
这里没数据么？
搜一下spring与dwr整合
web.xml里面也没有配置上dwr

<servlet-name>dwr-invoker</servlet-name>  

<servlet-class>  

    org.directwebremoting.spring.DwrSpringServlet   

</servlet-class>  

<init-param>  

    <param-name>debug</param-name>  

    <param-value>true</param-value>  

</init-param>  

<servlet-name>dwr-invoker</servlet-name>  

<url-pattern>/dwr/*</url-pattern>  

配置applicationContext.xml文件
引入

<dwr:configuration></dwr:configuration><!-- 必须要configuration -->  

<dwr:controller id="dwrController" debug="true" />  

<!-- DWR 配置结束 -->
