spring mvc+dwr 1的一个奇怪的问题

最近在搞的一个应用,用spring 1的MVC+hibernate 3+DWR1的,结果发现个奇怪的问题.其中用DWR1的地方也就是

在用户注册的时候,判断这个用户是否存在,这个用DWR1去做的,代码如下

  dwr的配置

    
<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN" "http://www.getahead.ltd.uk/dwr/dwr10.dtd">

<dwr>

 <allow>

  <convert converter="bean" match="liao.*"/>

  <create creator="spring" javascript="MemberManager">

          <param name="beanName" value="userFacade"/>

        </create>

 </allow>

</dwr>

   但运行的时候老说Dwr找不到userFacade这个方法,我再次检查了所有环节,根本没错,与以前的程序代码都是一样的,查了很久,最后终于给我发现问题了.

原来我的这个应用,将保存DAO和配置facade等的配置文件没有命名为applicationContext!,以mode-config.xml命明了，虽然我在WEB.XML中另外

指定了对应的新的名称,但估计DWR不收货!(起码是DWR1不收货,所以错了!),一般来说,应该这样的结构吧,建议

applicationContext.xml:存放DAO及facade模式配置的xml,比如

  

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN"

 "http://www.springframework.org/dtd/spring-beans.dtd">

 <beans>

    <!-- 要设定您的数据库相关消息 -->

   <!--  <bean name="openSessionInViewInterceptor" class="org.springframework.orm.hibernate3.support.OpenSessionInViewInterceptor">

    <property name="sessionFactory">

          <ref bean="mysessionFactory"/> 

            </property> 

         </bean>-->

    <bean id="dataSource"

          class="org.springframework.jdbc.datasource.DriverManagerDataSource">

        <property name="driverClassName">

            <value>com.mysql.jdbc.Driver</value>

        </property>

        <property name="url">

            <value>jdbc:mysql://localhost:3306/springlover</value>

        </property>

        <property name="username">

            <value>root</value>

        </property>

        <property name="password">

            <value>2222</value>

        </property>

    </bean> 

 

    <bean id="mysessionFactory"

          class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"

          destroy-method="close">

        <property name="dataSource">

            <ref bean="dataSource"/>

        </property>

        <property name="mappingResources">

          <list>

      <value>liao/domain/User.hbm.xml</value>

      <value>liao/domain/Photo.hbm.xml</value>

      <value>liao/domain/Comment.hbm.xml</value>

      <value>liao/domain/Admin.hbm.xml</value>

            </list>

        </property>

        <property name="hibernateProperties">

            <props>

                <prop key="hibernate.dialect">

                    org.hibernate.dialect.MySQLDialect

                </prop>

            </props>

        </property>

    </bean>

            

    <bean id="userDao"

           class="liao.dao.hibernate.UserDAO">

        <property name="sessionFactory">

   <ref local="mysessionFactory" />

  </property>      

     </bean>

        <bean id="photoFacade" class="liao.domain.logic.impl.PhotoFacadeImpl">

  <property name="photoDao">

   <ref bean="photoDao"/>

  </property>

 </bean>

   </beans>

而要再搞个应用名-servlet.xml,比如springlover-servlet.xml,里面的是controller等的设置,如

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN/EN"

 "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>

    <bean id="urlMapping"

          class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

           <property name="mappings">

            <props>

             <prop key="/login.do">loginController</prop>

                <prop key="/register.do">registerController</prop>

             <bean id="viewResolver"

          class="org.springframework.web.servlet.view.InternalResourceViewResolver">

      <property name="viewClass">

            <value>org.springframework.web.servlet.view.JstlView</value>

        </property>       

        <property name="prefix">

            <value>/</value>

        </property>

        <property name="suffix">

            <value>.jsp</value>

        </property>

    </bean>

  

<bean id="voteController" class="liao.web.VoteController">

  <property name="photoFacade">

   <ref bean="photoFacade" />

  </property>

  <property name="successView">

   <value>/index</value>

  </property>

</bean>

</beans>

最后是web,xml

 

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
