春季安全：無法解析參考豆，同時設置構造函數的參數

我實現記住我在春天security.And這裏是我的配置春季安全：無法解析參考豆，同時設置構造函數的參數

<bean id="rememberMeServices" 
      class="com.spring.security.service.WMPersistentTokenBasedRememberMeServices"> 
     <constructor-arg name="userDetailsService" ref="loginService"/> 
     <property name="tokenValiditySeconds" value="300"></property> 
</bean> 


<security:http auto-config="false" use-expressions="true" entry-point-ref="appAuthenticationEntryPoint"> 
     <!-- Interceptor urls --> 
     <security:remember-me user-service-ref="#{rememberMeServices.getUserDetailsServiceInstance()}" token-repository-ref="#{rememberMeServices.getTokenRepository()}" /> 
</security:http>

而且我WMPersistentTokenBasedRememberMeServices看起來像

public class WMPersistentTokenBasedRememberMeServices extends PersistentTokenBasedRememberMeServices { 

    private static final String key = "WM_APP_KEY"; 

    private static final PersistentTokenRepository tokenRepository = new InMemoryTokenRepositoryImpl(); 

    public WMPersistentTokenBasedRememberMeServices(UserDetailsService userDetailsService) { 
     super(key, userDetailsService, tokenRepository); 
    } 

    public PersistentTokenRepository getTokenRepository() { 
     return tokenRepository; 
    } 

    public UserDetailsService getUserDetailsServiceInstance() 
    { 
     return getUserDetailsService(); 
    } 
}

但是當我用以上配置部署應用程序，我是以下錯誤的獲取者

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#61fc8560': Cannot resolve reference to bean 'org.springframework.security.web.authentication.rememberme.PersistentTokenBasedRememberMeServices#0' while setting bean property 'logoutHandlers' with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.authentication.rememberme.PersistentTokenBasedRememberMeServices#0': Cannot resolve reference to bean '#{rememberMeServices.getTokenRepository()}' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinition 
Exception: No bean named 'org.springframework.security.web.authentication[email protected]' is defined 


Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.authentication.rememberme.PersistentTokenBasedRememberMeServices#0': Cannot resolve reference to bean '#{rememberMeServices.getTokenRepository()}' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.sec[email protected]2a13c5e' is defined

當我刪除使用

<security:remember-me ...>

標籤彈簧表達式語言，並提供有效的用戶參考實例，它工作正常。

但是，當我使用春天的表達語言，它與上述錯誤失敗。我懷疑與bean創建的順序。

任何人有關於這個錯誤的想法？

錯誤消息說明了一切：

Exception: No bean named 'org.springframework.sec[email protected]2a13c5e' is defined

令牌倉庫不是一個bean。事實上，如果你看看你的代碼，TokenRepository是一個靜態字段。而不是使用一個靜態字段，聲明爲一個bean：在你的XML配置，添加類似：

<bean id="tokenRepository" 
     class="org.springframework.security.web.authentication.rememberme.InMemoryTokenRepositoryImpl"/>

並且用類似替換靜態字段：

@Autowired 
private PersistentTokenRepository tokenRepository;

春天，作爲一個依賴注入框架提供了有用的機制來避免使用靜態引用：只使用這些機制。

即使按照您的建議進行更改，仍然會收到錯誤消息。設置構造函數參數時無法解析對bean＃{rememberMeServices.getTokenRepository（）}的引用;嵌套異常是org.springframework.beans.factory.NoSuchBeanDefinitionException：沒有名爲'org.springframework.sec[email protected]4d19bf23'的bean。豆類正在創建和自動裝配。我唯一關心的是表達式語言在春季安全標籤中沒有解決。 –
