在使用maven集成两个不同的项目时，我面临着这个问题

SpringHibernateAnnotationExample

是一个包含服务和dao相关内容的项目

Test是一个基于web的项目，包含jsf和primefaces相关的jar

现在我的问题是，在将

SpringHibernateAnnotationExample

集成到测试（Web）中时，我遇到了一些问题，我将对此进行详细阐述

SpringHibernateAnnotationExample

有BeanLocation.xml，它具有spring配置

测试具有单独的applicationContext文件

现在我正在web.xml中配置BeanLocation，但是当我运行带有jsf页面的应用程序时，我遇到了一些我无法理解的异常：

Hello World JSF示例
你好，世界第一

我知道这不是一个很好的例子，但我唯一的目的是将spring相关bean的依赖注入jsf/web应用程序，其中我在web项目（Test）中有applicationContext，在不同的项目中有其他applicationContext（BeanLocation.xml）

尝试在bean HelloWorld.java中添加

@Component

，并首先将所有

标记放在web中。xml

@Autowired

在

@ManagedBean

上不起作用，您必须在JSf bean上使用

@ManagedProperty

。这就是我在中尝试使用@Component时得到的结果HelloWorld这就是当我尝试在HelloWorld:：org.springframework.beans.factory.BeanCreationException中使用@component时得到的结果：创建名为“HelloWorld”的bean时出错[C:\apache-tomcat-7.0.64\webapps\WebPrrimeFaces-0.0.1-SNAPSHOT\WEB-INF\classes\com\java\view\HelloWorld.class]：bean实例化失败；嵌套异常为org.springframework.beans.beanstantiationException:未能实例化[com.java.view.HelloWorld]：构造函数引发异常；嵌套的异常是java.lang。NullPointerException@Component（value=“helloWorld”）@范围
