春のセキュリティコンテキストからアプリケーションコンテキストにアクセスする

承認にSpringセキュリティを使用するSpringMVCアプリケーションがあります。

ユーザーを承認するカスタムAuthenticationProviderを実装しました。

このカスタムAuthenticationProviderで、アプリケーションコンテキストで定義されたBeanにアクセスしたいと思います。

これは可能ですか？もしそうなら、どのように？

web.xml：

 ...
 <context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>WEB-INF/spring-security.xml</param-value>
 </context-param>
  ...
 <listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>
  ...
 <servlet>
  <servlet-name>dispatcher</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
 </servlet>

 <servlet-mapping>
  <servlet-name>dispatcher</servlet-name>
  <url-pattern>/</url-pattern>
 </servlet-mapping>

spring-security.xml：

  ...
  <authentication-manager>
    <authentication-provider ref="customAuthenticationProvider"/>
  </authentication-manager>

  <beans:bean class="com.example.davvstest.CustomAuthenticationProvider" id="customAuthenticationProvider">
    <beans:property name="loginService" ref="loginService" />
  </beans:bean>
  ...

ディスパッチャー-servlet.xml：

  <bean class="com.example.davvstest.LoginService" name="loginService">
  </bean>

CustomAuthenticationProvider.java：

package com.example.davvstest;

import org.springframework.security.authentication.AuthenticationProvider;
import org.springframework.security.core.Authentication;
import org.springframework.security.core.AuthenticationException;

public class CustomAuthenticationProvider implements AuthenticationProvider {

    private LoginService loginService;

    public LoginService getLoginService() {
        return loginService;
    }

    public void setLoginService(LoginService loginService) {
        this.loginService = loginService;
    }

    @Override
    public Authentication authenticate(Authentication authentication)
            throws AuthenticationException {
        if (!loginService.checkAuth(authentication.getName())){
            throw new BadUserNameException("Bad username");
        }
        return authentication;
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return true;
    }

}

LoginService.java：

package com.example.davvstest;

public class LoginService {

    public LoginService() {
    }

    public boolean checkAuth(String username){
        return true;
    }
}

私が得るエラーは次のとおりです。
