log4j:WARN No appenders could be found for logger (org.hibernate.cfg.annotations.Version).
log4j:WARN Please initialize the log4j system properly.

自学hibernate，看的是尚学堂，马士兵的hibernate3.3.2的视频，在构建log4j这个日志时候由于出现了问题后，我重头一步一步的按照马老师的步骤进行，下了和老师一样的架包，不过我用的是eclipse 3.5的，mysql 6.0 。

1.
hibernate.cfg.xml：
<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>


<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost/hibernate</property>
<property name="connection.username">root</property>
<property name="connection.password">364200</property>


<property name="connection.pool_size">1</property>


<property name="dialect">org.hibernate.dialect.MySQLDialect</property>


<property name="current_session_context_class">thread</property>


<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>


<property name="show_sql">true</property>
<property name="format_sql">true</property>


<property name="hbm2ddl.auto">update</property>

<mapping class="com.geolo.hibernate.model.Teacher"/>
</session-factory>
</hibernate-configuration>

teacher.java

package com.geolo.hibernate.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Teacher {
private int id;

private String name;
private String title;

@Id
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}

@Column
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

@Column
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}

teachertest.java

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;

import com.geolo.hibernate.model.Student;
import com.geolo.hibernate.model.Teacher;

public class TeacherTest {
public static void main(String[] args){
Teacher t = new Teacher();
t.setId(111);

t.setName("huhu");
t.setTitle("p");

Configuration cfg = new AnnotationConfiguration();

SessionFactory sf = cfg.configure().buildSessionFactory();
Session session = sf.openSession();
session.beginTransaction();
session.save(t);
session.getTransaction().commit();
session.close();
sf.close();
}
}

最佳答案：因为你把这句给注释掉了打开就没问题了我也出的这个毛病
log4j.rootLogger=warn, stdout

logger没有找到
log4j.rootLogger=debug,logger注意这个地方（logger）
log4j.appender.logger=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logger.File=E:/logs/DataTransfer.log
#log4j.appender.logger.File=${catalina.home}/logs/SupportWS.log
#log4j.appender.logger.MaxFileSize=10MB
#log4j.appender.logger.MaxBackupIndex=1000
log4j.appender.logger.layout=org.apache.log4j.PatternLayout
log4j.appender.logger.layout.ConversionPattern=[DataTransfer][%d{yyyy-MM-dd HH\:mm\:ss}][%l]\:%m%n

楼上的都是浑水摸鱼吗？
让我来给终结一下吧
log4j:WARN No appenders could be found for logger (XXXXX).
log4j:WARN Please initialize the log4j system properly.
一般情况下，说明你的log4j.properties内容或位置配置不当，但不会影响你的其他操作。
so，有2种方法参考一下：
第一，修改你的log4j.properties文件，大概如下：



# Configure logging for testing: optionally with log file

log4j.rootLogger=WARN, stdout

# log4j.rootLogger=WARN, stdout, logfile



log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n



log4j.appender.logfile=org.apache.log4j.FileAppender

log4j.appender.logfile.File=target/spring.log

log4j.appender.logfile.layout=org.apache.log4j.PatternLayout

log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n

第二，挪挪log4j.properties的地方，1是按照官方的英文说明应该首选放在src下的或者部署的路径下，2是放在指定路径下如WEB-INF/config/log4j.properties，这时，你就需要在web.xml里指定路径了，参考配置代码：

<!-- Log4J的配置信息 -->

	<context-param>

		<param-name>webAppRootKey</param-name>

		<param-value>logs.root</param-value>

	</context-param> 

	<context-param>

		<param-name>log4jConfigLocation</param-name>

		<param-value>/WEB-INF/log4j.properties</param-value>

	</context-param>

	<context-param>

		<param-name>log4jRefreshInterval</param-name>

		<param-value>60000</param-value>

	</context-param>

	<listener>

		<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>

	</listener>

在此，强烈建议放在src下，换路径配置时不能保证没有警告信息。
