Spring 当作为Windows服务运行时，Red5应用程序正在获取BeanCreationException

我有一个在Eclipse中运行良好的Red5应用程序。但是，当我构建应用程序并尝试将其作为Windows服务运行时，我遇到了一个错误

应用程序启动后，当它尝试启动Red5服务器时，我得到以下错误/堆栈跟踪：

我的相关代码如下：

    // get current loader
    logDebug("   about to get baseLoader");
    ClassLoader baseLoader = Thread.currentThread().getContextClassLoader();
    // build a ClassLoader
    logDebug("   about to get loader: " + baseLoader);
    ClassLoader loader = ClassLoaderBuilder.build();
    // set new loader as the loader for this thread
    logDebug("   about to set new loader:" + loader);
    Thread.currentThread().setContextClassLoader(loader);
    // create a new instance of this class using new classloader
    logDebug("   about to create boot object: " + loader);
    Object boot = Class.forName("org.red5.server.Launcher", true, loader).newInstance();
    logDebug("   about to get method 1: " + boot);
    Method m1 = boot.getClass().getMethod("launch", (Class[]) null);
    logDebug("   about to invoke method 1: " + m1);
    m1.invoke(boot, (Object[]) null);   
    // not that it matters, but set it back to the original loader
    logDebug("   about to set original loader: " + m1);
    Thread.currentThread().setContextClassLoader(baseLoader);

知道是什么原因导致错误以及如何修复错误吗？

编辑：

我向red5根目录添加了一个名为red5.root set的系统属性，如下所示，它消除了我在上面遇到的nullPointerException

String red5Root = serverHome + "/red5-server-1.0.6-RELEASE";
System.setProperty("red5.root", red5Root);

但是，我在连接red5服务器时仍然遇到问题。当我尝试使用以下url访问我的web应用程序时：

localhost:8080/streaming/streaming.html

我得到一个500错误，但有一个例外：

java.lang.NullPointerException org.red5.logging.LoggerContextFilter.doFilter（LoggerContextFilter.java:64）

---

是什么原因导致此NullPointerExection？

由于第一个问题在编辑中已经得到了某种程度的回答，我将只回答第二个问题

NPE发生的原因是类路径中存在冲突的日志JAR。通过从我的webapps/myApp/WEB-INF/WEB.xml文件中删除以下内容，我能够解决这个问题

 <filter>
     <filter-name>LoggerContextFilter</filter-name>
     <filter-class>org.red5.logging.LoggerContextFilter</filter-class>
 </filter>

 <filter-mapping>
     <filter-name>LoggerContextFilter</filter-name>
     <url-pattern>/*</url-pattern>
 </filter-mapping>

LoggerContextFilter
org.red5.logging.LoggerContextFilter
LoggerContextFilter
