无法使用不同的应用程序上下文重新初始化

Question

我使用Mule with 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上下文，因此低于错误：

任何大师都可以帮助分析这个问题？如果我不包含这个xml，那就没问题。如何让SI和Spring一起工作？

Answer 1

所以这是根本原因

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XML命名空间。也许你只是错误地复制粘贴它然后你的背景发生了冲突。

另请检查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

发生了这种情况，因为你将mule spring配置与SI混合，其中一些组件无法识别。你能尝试分离SI配置，然后将其导入到mule配置吗？如下所示：

import pandas as pd
reader = pd.read_stata('file.dta', iterator = True)

另外，请通过比较EE 3.7.2使用的弹簧框架版本和您使用的SI来检查您是否使用了正确版本的Spring Integration。
