如何自動連接服務作為構造函數參數？

Question

我有以下服務：

public interface LogoutService {
    void logoutAllUsers();

    void dropUserSession(SessionInformation session);
}

以及以下實現：

@Service
public class LogoutServiceImpl implements LogoutService {
    ...

---

public class MyXmlBean extends ConcurrentSessionControlAuthenticationStrategy {
    ....

       public MyXmlBean (MySessionRegistry sessionRegistry,
                                                              LogoutService logoutService) {
             ....

以及以下xml配置：

<bean id="MyXmlBean" class="package.MyXmlBean">
    <constructor-arg name="sessionRegistry" ref="mySessionRegistry" />
    <constructor-arg name="logoutService" ref="logoutService"/>
    <property name="maximumSessions" value="1" />
</bean>

當我啟動應用程序時-我看到以下錯誤：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myXmlBean ' defined in class path resource [context-security.xml]: Cannot resolve reference to bean 'myXmlBean ' while setting constructor argument with key [1]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'MyXmlBean' defined in class path resource [context-security.xml]: Cannot resolve reference to bean 'logoutService' while setting constructor argument; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'logoutService' is defined

如何解決？

我發現

@Service注釋是從錯誤的包中導入的（非春季）
