java - 您的处理程序是否实现了像 Controller 这样受支持的接口(interface)？

Question

添加mvc:resource后，我的应用程序抛出如下错误

"javax.servlet.ServletException: No adapter for handler [com.test.web.controller.AppController@190cf5c]: Does your handler implement a supported interface like Controller?"

当我使用以下配置时，它工作正常，

          <?xml version="1.0" encoding="UTF-8"?>
       <beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"       xsi:schemaLocation="http://www.springframework.org/schema/beans       http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

     http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd">

 <mvc:resources mapping="/help/**" location="/help/" />
<!-- View Resolver -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/jsp/" p:suffix=".jsp" />

<bean id="xmlFileViewResolver" class="org.springframework.web.servlet.view.XmlViewResolver">
    <property name="location">
        <value>/WEB-INF/views.xml</value>
    </property>
    <property name="order">
        <value>1</value>
    </property>
</bean> 

但是当我添加 Controller 时出现错误。请检查以下配置

 <?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

    <property name="location">

    </property>
    <property name="order">
        <value>1</value>
    </property>
</bean>


<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <!-- one of the properties available; the maximum file size in bytes -->
    <!-- maximum file size (1 megabyte) -->
    <property name="maxUploadSize" value="6048576" />
</bean>

<bean id="urlMapping"   class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">


    <property name="mappings">
        <props>
            <!-- Login -->
            <prop key="/login.htm">appController</prop> 
            <prop key="/index.htm">appController</prop>

            </props>
    </property>
</bean>


<bean name="appController" class="com.test.web.controller.AppController" >
    </bean>

但如果我删除

<mvc:resources mapping="/help/**" location="/help/" />

这个标签，工作正常。我花了很多时间来解决这个问题:(提前致谢

Answer 1

添加这两个标签后，终于成功了..

<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/> 
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
    <property name="order" value="0"/>
</bean>          

谢谢大家:)
