无法使用不同的应用程序上下文重新初始化

Question

我正在使用Mule和Spring Integration实现发送短信功能，下面是spring xml配置：

    <?xml version="1.0" encoding="UTF-8"?>

似乎尝试初始化第二个 spring-integration context ，所以出现以下错误：

哪位高手可以帮忙分析一下这个问题？如果我不包括这个 xml ，那就没问题了。如何让 SI 和 Spring 协同工作？

Answer 1

这是根本原因

Cannot reinitialize with different application context: current one is
[org.mule.config.spring.MuleDomainContext@1825085: 
startup date [Tue Mar 22 17:21:29 CST 2016]; root of context hierarchy], 
passed-in one is [org.mule.config.spring.MuleArtifactContext@14f3da4: 
startup date [Tue Mar 22 17:21:33 CST 2016]; 
parent: org.mule.config.spring.MuleDomainContext@1825085] at 
org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:547)

检查您的 XML 命名空间。也许您只是错误地复制粘贴了它，然后您的上下文就发生了冲突。

还要检查您的 integrationRequestMappingHandlerMapping bean 定义。碰巧它是由不同的上下文初始化的。请附上它的定义。

Answer 2

发生这种情况是因为您将 mule spring 配置与 SI 混合在一起，其中某些组件无法识别。您可以尝试分离 SI 配置，然后将其导入 mule 配置吗？如下：

<?xml version="1.0" encoding="UTF-8"?>
  <mule xmlns=http://www.mulesoft.org/schema/mule/c... ....>
     <spring:beans>
        <spring:import resource="si-config.xml" />
     </spring:beans>

另外，请通过比较EE 3.7.2和你使用的SI使用的spring框架版本来检查你是否使用了正确的Spring Integration版本。
