linux - 为什么 Mule 应用程序在 Linux 服务器中表现异常？

Question

我和 Mule 一起工作，但遇到了一些问题。

我的 mainflow.xml:

<?xml version="1.0" encoding="UTF-8"?><mule xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:vm="http://www.mulesoft.org/schema/mule/vm"

在 Tomcat 中一切正常。但是在那之后我提交了对 SVN 的更改，检查了所有内容，打包没有更改并在 Tomcat 中部署应用程序我的应用程序不工作!

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，在这行之后我看到

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

如果我有这个错误并从 mainflow.xml 中删除 mx4j 和 notifications 的部分，一切都会再次运行:

<?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>

在我一步步编写了mx4j和notifications部分之后，不要粘贴我从SVN获取的文件的所有文本，它又可以工作了!因此，当应用程序工作和不工作时，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。我想过斜线之间的区别，但我不写斜线...

为什么应用程序的行为如此奇怪？

根据您提供的信息，我只能猜测您在通知中有一些逻辑可以挂起它们，如果它们所依赖的东西尚未以某种方式初始化的话。

后来它确实起作用的事实在某种程度上表明了这一点。我可以建议您在 bean 中使用该属性所依赖的属性，以确保它在您的 bean 依赖项之后被初始化，以防万一。
