Question

我對測試工作的例子通過創建配置並創建了所有必要的文件spring3寧靜project.i但是當我開始我的服務器我得到下面的錯誤-----

揭露擴展在@jbnizet評論... 「實現類必須通過宣佈它是一個Spring bean。無論是XML文件，或通過使用Spring註釋進行註釋（例如組件或服務）「。

您可以添加這appContext：

<context:component-scan base-package="com.yourbasepackage"/> 

，將允許您添加annoation

@Service("uniservService") 
public class UniservServiceJPAImpl implements UniservSearchInterface { 
} 

，然後你可能也希望這些爲更全面的註釋處理：

<!--Indicates that transaction configuration is defined by Java 5 
    annotations on bean classes --> 
<tx:annotation-driven transaction-manager="yourtransactionManager"/> 

<!-- Activates various annotations to be detected in bean classes: Spring's @Required and 
    @Autowired, as well as JSR 250's @PostConstruct, @PreDestroy and @Resource (if available) --> 
    <context:annotation-config/>
