java - HandlerInterceptorAdaptarer Spring - Invalid content was found starting with element 'bean' -

i'm trying make handlerinterceptoradaptarer work.

my class extends handlerinterceptoradapter

package br.com.caelum.tarefas.interceptor;  import javax.servlet.http.httpservletrequest; import javax.servlet.http.httpservletresponse;  import org.springframework.web.servlet.handler.handlerinterceptoradapter;  public class autorizadorinterceptor extends handlerinterceptoradapter{      public boolean prehandle(httpservletrequest request,httpservletresponse response,object controller){         string uri = request.getrequesturi();         if(uri.endswith("loginform") || uri.endswith("efetualogin") || uri.contains("resources")){             return true;         }          if(request.getsession().getattribute("usuariologado") != null){             return true;         }          return false;            }  } 

after went servlet-context.xml , added

<interceptors>     <bean class="br.com.caelum.tarefas.interceptor.autorizadorinterceptor" /> </interceptors> 

the full servlet-context.xml became:

    <?xml version="1.0" encoding="utf-8"?> <beans:beans xmlns="http://www.springframework.org/schema/mvc"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns:beans="http://www.springframework.org/schema/beans"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemalocation="http://www.springframework.org/schema/mvc     http://www.springframework.org/schema/mvc/spring-mvc.xsd     http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans.xsd     http://www.springframework.org/schema/context     http://www.springframework.org/schema/context/spring-context.xsd">      <!-- dispatcherservlet context: defines servlet's request-processing infrastructure -->      <!-- enables spring mvc @controller programming model -->     <annotation-driven />      <!-- handles http requests /resources/** efficiently serving static resources in ${webapproot}/resources directory -->     <resources mapping="/resources/**" location="/resources/" />      <!-- resolves views selected rendering @controllers .jsp resources in /web-inf/views directory -->     <beans:bean class="org.springframework.web.servlet.view.internalresourceviewresolver">         <beans:property name="prefix" value="/web-inf/views/" />         <beans:property name="suffix" value=".jsp" />     </beans:bean>      <context:component-scan base-package="br.com.caelum" />       <interceptors>         <bean class="br.com.caelum.tarefas.interceptor.autorizadorinterceptor" />     </interceptors>   </beans:beans>

eclipse showing me:
