发布个rmi服务居然出现如下:

RMI其实发布成功了...
为什么开始有错呢？
查看源代码发现：其实是Spring的Debug log
他会先看有没rmi注册
org.springframework.remoting.rmi.RmiServiceExporter.testRegistry(RmiServiceExporter.java:411)没有log下再 Could not detect RMI registry - creating new one所以屏蔽该Log4j配置文件中加如：
log4j.logger.org.springframework.remoting.rmi.RmiServiceExporter=INFO
