无法在Spring Webapp中注入Activiti框架服务
我试图使用Activiti和Spring
MVC框架在Web应用程序中创建工作流，因此我必须通过applicationContext.xml文件注入Activiti
Services，然后自动装配这些服务。
这是JUnit测试后的consol中的问题
GRAVE：在允许TestExecutionListener
[org.springframework.test.context.support.DependencyInjectionTestExecutionListener@14c8743]准备测试实例[tds_erp.testSpring@144719c]
org.springframework.beans.factory.BeanCreationException时捕获了异常：创建名称为’tds_erp的bean时出错.testSpring’：自动连接的依赖项注入失败；嵌套的异常是org.springframework.beans.factory.BeanCreationException：无法自动连线字段：org.activiti.engine.RepositoryService
tds_erp.testSpring.repositoryService;
嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有找到类型为[org.activiti.engine.RepositoryService]的合格Bean作为依赖项：预计至少有1个Bean可以作为此依赖项的自动装配候选。依赖注释：

请帮帮我 ！
回答：
看来您想在测试用例中使用applicatioContext.xmllike repositoryService等定义的bean
。但是您要声明的the @ContextConfiguration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：
@ContextConfiguration("classpath:applicatioContext.xml")只是一个建议：创建一个单独applicatioContext.xml的测试上下文类似于webapplicationContext中的上下文可能是一个好主意。这将有助于保留其他数据等，与常规开发数据库实例相比，您可以在其中更好地管理数据的前后条件。您甚至可能想为测试本身生成一个数据库实例，并在测试后将其拆除。
编辑：您可以给多个conf文件，例如- @ContextConfiguration(locations = {
"classpath:applicatioContext.xml" ,
"classpath*:activiti.cfg.xml"})。检查这篇文章。
除非您更改了默认位置，否则通常定义为“ <bean id="processEngineConfiguration"
class="org.activiti.spring.SpringProcessEngineConfiguration">”的内容应在activiti.cfg.xml内部加载。
