爲什麼我會收到以下錯誤？ 「沒有定義類型的唯一bean：期望單個匹配的bean但發現3」

我們使用Eclipse Kepler IDE來開發我們的GWT應用程序，並且已經使用Ant腳本長時間部署到Tomcat容器。我們最近決定改用Hudson CI服務器來簡化GWT編譯和部署過程。我們遇到的問題是，當我們允許Eclipse執行它自己的連續構建時，然後執行GWT編譯/部署，我們的應用程序按預期工作。然而，當我們使用外部的javac程序編譯，無論是從一個獨立的JDK或使用Eclipse的編譯器（org.eclipse.jdt.core.JDTCompilerAdapter），我們收到以下錯誤信息：爲什麼我會收到以下錯誤？ 「沒有定義類型的唯一bean：期望單個匹配的bean但發現3」

Error creating bean with name 'loginServiceImpl' defined in file [/opt/tomcat/webapps/ROOT##10616/WEB-INF/classes/com/company/ribeye/server/service/LoginServiceImpl.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.security.authentication.AuthenticationManager]: : No unique bean of type [org.springframework.security.authentication.AuthenticationManager] is defined: expected single matching bean but found 3: [org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0, org.springframework.security.authentication.ProviderManager#0, org.springframework.security.authenticationManager]; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [org.springframework.security.authentication.AuthenticationManager] is defined: expected single matching bean but found 3: [org.springframework.security.config.authentication.AuthenticationManagerFactoryBean#0, org.springframework.security.authentication.ProviderManager#0, org.springframework.security.authenticationManager]

我們沒有使用任何類型的依賴管理的，但Eclipse似乎處理java編譯沒有問題，我們不會遇到這個錯誤。當我們使用Ant任務和javac進行編譯時，我只想強調這個錯誤。同樣，即使使用Eclipse自己的捆綁編譯器，我們也會遇到問題。我還想補充一點，我不是Java開發人員，但是我是開發團隊的DevOps經理，所以CI服務器和部署策略屬於我的領域。我有一點Java知識，並且仍在學習，所以如果這是非常簡單的事情，我提前道歉。

這裏是我的相關代碼（未列出的所有進口，爲簡潔起見）：

您的LoginServiceImpl似乎是一個控制器，並且它沒有@Controller註釋 – RanPaul 2014-10-11 00:01:28

一番搜索後，我能找到解決辦法，有人在#spring（freenode上）給了我。我仍然不知道爲什麼這不是Eclipse內部的問題，但至少現在它正在工作。

雖然我不能在我們的應用程序，其中正在創建的另外兩個豆類發現，加入@Qualifier("authenticationManager")註釋LoginServiceImpl解決了這個問題：

@Autowired 
    public LoginServiceImpl(@Qualifier("authenticationManager") AuthenticationManager authenticationManager, UserDao userDao, 
      UserPreferenceDao userPreferenceDao) { 
     this.authenticationManager = authenticationManager; 
     this.userDao = userDao; 
     this.userPreferenceDao = userPreferenceDao; 
    }
