Question

我和骡子一起工作，我有一些问题。

我的mainflow.xml：

Tomcat中的一切正常。但之后我提交了对SVN的更改，检查了所有内容，包没有更改并在Tomcat中部署应用程序我的应用程序不起作用！

我的应用程序的Tomcat日志中的最新文本：

DEBUG 18.12.2014 15:12:08 997 - DisposableBeanAdapter.invokeCustomDestroyMethod - Invoking destroy method 'dispose' on bean with name '_muleSystemModel'
INFO 18.12.2014 15:12:08 997 - ModelLifecycleManager.fireDisposePhase - Disposing model: _muleSystemModel

并且没有任何关于错误的日志...... 当应用程序工作正常时，在这行后我看到

DEBUG 18.12.2014 10:59:53 765 - MuleXmlBuilderContextListener.initialize - Mule config file(s): WEB-INF/classes/mainflow.xml

如果我有此错误并从mx4j和notifications的mainflow.xml部分删除，则所有内容都会重复：

<?xml version="1.0" encoding="UTF-8"?><mule xmlns="http://www.mulesoft.org/schema/mule/core" mlns:vm="http://www.mulesoft.org/schema/mule/vm" xmlns:file="http://www.mulesoft.org/schema/mule/file" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" xmlns:core="http://www.mulesoft.org/schema/mule/core" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="CE-3.3.0" xsi:schemaLocation="http://www.mulesoft.org/schema/mule/vm http://www.mulesoft.org/schema/mule/vm/current/mule-vm.xsd http://www.mulesoft.org/schema/mule/file http://www.mulesoft.org/schema/mule/file/current/mule-file.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd http://www.mulesoft.org/schema/mule/http http://www.mulesoft.org/schema/mule/http/current/mule-http.xsd ">
</spring:beans>
<file:connector name="input" autoDelete="true" doc:name="File" />
<flow name="UnpackHandler" doc:name="UnpackHandler">
    ...
</flow>
<flow name="XmlToCsvTransformHandler" doc:name="XmlToCsvTransformHandler">
    ...
</flow>

在我逐步编写mx4j和notifications的部分后，不要粘贴我从SVN获取的文件的所有文本，它再次起作用！因此，当应用程序工作且不起作用时，mainflow.xml之间没有区别。

此行为在Linux服务器中。在Windows服务器和我的本地计算机中一切正常。我想到了斜杠之间的差异，但我不写斜线......

为什么应用程序表现得如此奇怪？

Answer 1

根据您提供的信息，我只能猜测，如果它们所依赖的某些内容尚未以某种方式初始化，那么挂起它们的通知中就会有一些逻辑。

以后它确实起作用的事实会以某种方式表明这一点。我建议你在bean中使用属性依赖，以确保它在你的bean依赖之后被初始化，以防万一。
