我在 Tomcat 7 中运行的 webapp 重复相同的日志消息 6 次。例如：
[INFO] 1
29042 [http-nio-8443-exec-4] INFO com.lni.exchange.healthvault.ParseMeasurement - 1
29042 [http-nio-8443-exec-4] INFO com.lni.exchange.healthvault.ParseMeasurement - 1
29042 [http-nio-8443-exec-4] INFO com.lni.exchange.healthvault.ParseMeasurement - 1
29042 [http-nio-8443-exec-4] INFO com.lni.exchange.healthvault.ParseMeasurement - 1
29042 [http-nio-8443-exec-4] INFO com.lni.exchange.healthvault.ParseMeasurement - 1
29042 [http-nio-8443-exec-4] INFO com.lni.exchange.healthvault.ParseMeasurement - 1
预期的书面输出只是第一行（[INFO] 1），但随后我收到了 6 次重复该消息。有谁知道为什么该消息重复了这么多次？可能弄乱了我的 log4j 属性，这一直让我有点困惑。
我有一个使用 Spring 的 Axis2 1.6.2 部署，它接收数据并将其发送到 HealthVault。
这是 log4j 属性文件：
# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE
log4j.rootCategory=INFO, CONSOLE, LOGFILE
# Set the enterprise logger priority to FATAL
