将Spring Integration与Spring MVC结合使用时发生部署错误

标签： spring spring-mvc spring-integration

我已经在Spring Boot应用程序中对SI进行了poc验证，在那里我能够从TcpOutBoundGateway发送和接收消息。现在，我正在尝试将示例Spring集成模块合并到实际的企业Spring应用程序中。

为此，我在企业应用程序中添加了spring-integration.xml并将其导入spring-core.xml 

  <import resource="classpath:rx/spring-integration.xml" />

还添加了spring-integration-ip和spring-integration-core到build.gradle文件。 在我的服务类中，将我的SI bean自动接线

<bean id="rxService" class="com.api.services.RxService"/>

将创建要发送到网关的有效负载，并接收响应并解析结果并返回模型对象。 但是在启动tomcat时，出现以下错误。

这是我的SI配置，这是一个请求响应模型，其中客户端是我的应用程序

仅供参考-我们使用的是一个普通的jar，其中有一个名为buildDetails的bean，带有apiVersion属性。这是gradle multiflat项目，我正在处理的模块具有buildDetails.properties文件，该文件具有key-apiVersion和值。

现在令人困惑的部分是-仅当我仅在spring-core.xml中导入SI xml时，我才会收到此部署错误，甚至不必自动装配其服务bean。

如果您可以验证将SI集成到应用程序中的正确步骤，将很有帮助。

1 个答案:

答案 0 :(得分：0)

Web上下文是根应用程序上下文的子级；如果属性位于Web上下文中，则根上下文中的bean无法使用它们。

将属性移动到根上下文，以便它们对两者均可见。
