java - 未找到此类 Bean 定义 - 异常

Question

我有一个外部 jar 文件，它作为另一个 Web 应用程序的依赖项添加。当我独立运行此 Jar 文件时，它工作正常。

当我将其包含在我的网络应用程序中时，我收到以下错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'inviteAuditService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.trunym.certificateserver.datajpa.repository.InviteAuditRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

这是我的 Web 应用程序的应用程序上下文:

<import resource="classpath*:certificate-server-context.xml" />

<bean
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="ignoreUnresolvablePlaceholders" value="false" />

        <property name="placeholderPrefix" value="%{" />

Answer 1

我设法解决了这个问题，问题是我的网络应用程序和外部 jar 中的包名称存在冲突。

上下文组件扫描给出了问题。
