承認にSpring Securityを使用するSpring MVC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 が、アプリケーション コンテキストで定義された Bean にアクセスできるようにしたいと考えています。

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>

春のセキュリティ.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>
  ...

ディスパッチャーサーブレット.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。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains': Cannot resolve reference to bean 'org.springframework.security.web.DefaultSecurityFilterChain#0' while setting bean property 'sourceList' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.DefaultSecurityFilterChain#0': Cannot resolve reference to bean 'org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0' while setting constructor argument with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter#0': Cannot resolve reference to bean 'org.springframework.security.authentication.ProviderManager#0' while setting bean property 'authenticationManager'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authentication.ProviderManager#0': Cannot resolve reference to bean 'org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authenticationManager': Cannot resolve reference to bean 'customAuthenticationProvider' while setting constructor argument with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'customAuthenticationProvider' defined in ServletContext resource [/WEB-INF/spring-security.xml]: Cannot resolve reference to bean 'loginService' while setting bean property 'loginService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'loginService' is defined

親コンテキストは、子コンテキストからの依存関係を持つことはできません。

この場合、customAuthenticationProvider Bean は親コンテキストの一部であり、子 Web コンテキスト loginService からの依存関係があります。

だからあなたはすべきです

  1. 別の services-context.xml を作成し、loginService Bean 定義を dispatcher-servlet.xml から services-context.xml に移動します。
  2. contextConfigLocationweb.xml の値リストにservices-context.xml を追加します
