filenotfoundexception.ClassPath资源在Spring Osgi Jar中找不到

Question

我创建了一个示例OSGI插件并将其部署在WSO2-ESB容器中。
现在，我想在OSGI捆绑包中用户弹簧进行bean管理。因此，我创建了一个 springs.xml 文件，如下所示。

<beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://www.springframework.org/schema/beans
                            http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
                            http://www.springframework.org/schema/context
                            http://www.springframework.org/schema/context/spring-context-3.2.xsd">

    <!--  Add DAO Impl bean entry here and Add bean reference as required -->
    <bean id="xyzDAO" class="x.y.z.ABCImpl">
    </bean>
    <!-- Add Service Impl bean entry here and attach DAO reference -->
    <bean id="abcService" class="x.y.z.ABCServiceImpl">
        <property name="xyzDAO" ref="xyzDAO"/>
    </bean>

然后，我创建了一个类，并使用 classpathxmlapplicationContext 用于加载XML文件，如下所示

ApplicationContext appContext = new ClassPathXmlApplicationContext("spring-beans.xml");

我从 bundleactivator 中拨打了此类，该在捆绑启动上运行。
当我将此插件部署到 [WSO2-HOME]/repository/components/dropins/strong>我有以下例外。

当我从Eclipse运行此插件时，它运行平稳。
我无法弄清楚它为什么会发生的问题。如果您有任何建议或解决方案，请让我知道，以便我可以解决。
预先感谢。

Answer 1

而不是部署到[WSO2-home]/repository/components/dropins，

部署在[WSO2-home]/repository/components/lib。

中

必须重新启动服务器并再次检查。

，还要检查一下。
