解决方案
缺少jar包，通过运行你的项目，发现后台报错找不到类：logback下面的类，下载最新的logback的包，地址为：http://logback.qos.ch/download.html
解决方案二：
如果red5自带了slf,就把springmvc的删除看看。典型版本冲突。
解决方案三：
估计是red5.jar与slf4j-log4j12-1.6.6.jar中package和class重复造成的。你先用压缩软件打开red5.jar，然后删除org.slf4j.impl包，试试看会不会报错。
解决方案四：
java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class org.slf4j.impl.StaticLoggerBinder) Invocation of init method failed; nested exception is java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class org.slf4j.impl.StaticLoggerBinder) 即使用了不同版本的jdk编译的 造成不兼容估计你的slf4j太新了换成slf4j-api-1.5.6.jar试试https://red5.googlecode.com/files/Red5War_0.8.0.zip
