bean拒绝的原因以及没有标识URL路径意味着什么

Question

我使用的是spring:3.0：我在下面的xml文件中做了一些更改，以更新这个问题。

<servlet>
    <servlet-name>spring</servlet-name>
           <servlet-class>
           org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
    <load-on-startup>2</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
      </servlet-mapping>

我有更新的spring-servlet.xml：

    <bean id="localeChangeInterceptor"
            class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
            <property name="paramName" value="lang" />
        </bean>
        <bean id="localeResolver"
            class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
            <property name="defaultLocale" value="en" />
        </bean>
        <bean id="handlerMapping"
            class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
            <property name="interceptors">
                <ref bean="localeChangeInterceptor" />
            </property>
                </bean>
        <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
        <mvc:resources mapping="/images/**"  location="/images/"/>
        <mvc:resources location="/css/**" mapping="/css/"/>
        <mvc:resources location="/css/**" mapping="/css/"/>
        <mvc:default-servlet-handler/>
        <mvc:annotation-driven />
      <context:component-scan base-package="com.dz.hrportal.controller" />
    <bean       class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/jsp/" />
            <property name="suffix" value=".jsp" />
        </bean>
        <bean id="messageSource"
            class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
            <property name="basename" value="classpath:messages" />
            <property name="defaultEncoding" value="UTF-8" />
        </bean>

现在，我的网络应用程序似乎正在运行问题，我可以在服务器日志上看到：

为什么bean被拒绝，有人知道解决它的方法吗？

Answer 1

在春季文档中，它说

如果要定义自定义HandlerMappings或HandlerAdapters，则您需要确保相应的自定义DefaultAnnotationHandlerMapping和/或AnnotationMethodHandlerAdapter也被定义了——前提是您打算使用@RequestMapping。

由于您正在定义DefaultAnnotationHandlerMapping，因此还需要定义适配器：

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
