配置休眠时出现此错误
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.
这是代码行
Configuration config = new AnnotationConfiguration().configure("HibernatePositionServer.cfg.xml");
这是我的 cfg 文件
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

首先询问Google http://www.google.com/search?q=No+appenders+could+be+found+for+logger，这是最常见的 Log4J 错误消息之一。简单地说：Log4J（日志记录和监控框架）收到来自 Hibernate 的日志消息，但不知道如何处理它（在控制台上打印、放入文件、忽略...？）
将文件命名为log4j.xml在你的 CLASSPATH 根目录中（src/main/resource使用maven时）包含以下内容：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %c{1} - %m%n"/>
</layout>
</appender>
<root>
<priority value ="debug" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
