未能在Spring webapp中注入Activiti framework服务

Question

我试图使用Activiti和Spring MVC框架在我的web应用程序中创建一个工作流，因此我必须通过applicationContext.xml文件注入Activiti服务，然后autowire这些服务。

这就是JUnit测试后consol中的问题

Grave：允许TestExecutionListener[org.springframework.test.context.support.DependencyInjectionTestExecutionListener@14c8743]准备测试实例[tds_erp.testspring@144719c]org.springframework.beans.factory.beanCreationException：创建名为'tds_erp.testspring'的bean时出错：注入autowired依赖项失败；嵌套异常是org.springframework.beans.factory.beanCreationException：不能autowire字段：org.activiti.engine.repositoryservice tds_erp.testspring.repositoryservice；嵌套异常是org.springframework.beans.factory.nosuchBeanDefinitionException：没有找到用于依赖项的类型[org.activiti.engine.RepositoryService]的合格bean：预期至少有1个bean可以作为此依赖项的autowire候选bean。依赖注释：{@org.springframework.beans.factory.annotation.autowire(required=true)}

原因：org.springframework.beans.factory.beanCreationException：无法autowire字段：org.activiti.engine.repositoryservice tds_erp.testspring.repositoryservice；嵌套异常是org.springframework.beans.factory.nosuchBeanDefinitionException：没有找到用于依赖项的类型[org.activiti.engine.RepositoryService]的合格bean：预期至少有1个bean可以作为此依赖项的autowire候选bean。依赖注释：{@org.springframework.beans.factory.annotation.autowire(required=true)}

由：org.springframework.beans.factory.nosuchBeanDefinitionException引起：没有找到符合依赖项类型[org.activiti.engine.RepositoryService]的bean：预期至少有1个bean符合此依赖项的autowire候选项。依赖注释：{@org.springframework.beans.factory.annotation.autowire(required=true)}

求求你帮帮我！

看起来您希望在测试用例中使用applicatiocontext.xmllikerepositoryservice等中定义的bean。但是您在@contextconfiguration中声明的只是Activiti的默认配置文件activiti.cfg.xml您可以在测试中尝试以下操作吗：

@ContextConfiguration("classpath:applicatioContext.xml")

只是一个建议：为测试上下文创建一个单独的applicatiocontext.xml可能是一个好主意，类似于WebApplicationContext中的上下文。这将有助于保存不同的数据等，在那里您可以比正常的开发DB实例更好地管理数据的前/后条件。您甚至可能希望为测试本身生成一个DB实例，并在测试结束后拆除。

编辑：可以给出多个conf文件，如下所示-@contextconfiguration(locations={“classpath:applicatiocontext.xml”,“classpath*:activiti.cfg.xml”}）。查查这个帖子。
