spring 3.1註釋了獨立應用程序的自動裝配

我用eclipse編寫了這個應用程序，它的工作原理。但是當我將它作爲獨立/控制檯應用程序部署時，它找不到我注入的StartApp bean。這裏的代碼：spring 3.1註釋了獨立應用程序的自動裝配

主要應用：

@Component 
public class StartApp { 
    @Autowired 
    private Processor proc; 

    public StartApp() { 
     System.out.println("Starting App!"); 
    } 
    private void say() { 
     proc.say(); 
    } 
    public static void main(String[] args) { 
     ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml"); 
     StartApp app = ctx.getBean(StartApp.class); 
     app.say(); 
    } 
}

服務：

@Service 
public class Processor { 
    public Processor() { 
     System.out.println("Processor initialized!"); 
    } 
    public void say() { 
     System.out.println("hello!"); 
    } 
}

和applicationContext.xml中：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:p="http://www.springframework.org/schema/p" 
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-3.1.xsd 
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-3.1.xsd"> 

    <context:component-scan base-package="test.spring.desktop"/> 
</beans>

我沒有把所有的彈簧庫和記錄，包括SLF4J庫。和控制檯命令我把這些：

java -cp lib/*:lib/spring-3.1/*:test-spring-desktop.jar test.spring.desktop.StartApp

然後我得到了這些錯誤消息：

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [test.spring.desktop.StartApp] is defined: expected single bean but found 0: 
     at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBean(DefaultListableBeanFactory.java:271) 
     at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1101) 
     at test.spring.desktop.StartApp.main(StartApp.java:24)

哪裏又是怎樣的你的'StartApp' bean已定義？ – bvulaj 2012-04-05 14:48:35

它在同一個文件夾上。這裏的結構： /lib/spring-3.1/{all-spring3.1-lib} /lib目錄/ {SLF4J-庫} /test-spring-desktop.jar /啓動測試彈簧桌面.sh – 2012-04-09 03:04:30

抱歉我的評論亂七八糟，我仍然試圖在評論中獲得正確的格式。至於StartApp的 – 2012-04-09 03:07:24

嘗試把在applicationCntext.xml此配置：

<context:annotation-config />
