错误信息 : log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
                 log4j:WARN Please initialize the log4j system properly.
解决方法 : 在WEB-INF/classes/路径下加上文件 log4j.properties 其参考内容如下

# Set root logger level to error
log4j.rootLogger=INFO, Console, File

###### Console appender definition #######

# All outputs currently set to be a ConsoleAppender.
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{3}] %m%n
#log4j.appender.Console.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c] %m%n

###### File appender definition #######
log4j.appender.File=org.apache.log4j.DailyRollingFileAppender
log4j.appender.File.File=spring.log
log4j.appender.File.Append=false
log4j.appender.File.layout=org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c] %m%n

###### Hibernate specific appender definition #######
#log4j.appender.file=org.apache.log4j.FileAppender
#log4j.appender.file.File=hibernate.log
#log4j.appender.file.layout=org.apache.log4j.PatternLayout
#log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

###### Log level overrides #######

# Hibernate

log4j.logger.org.hibernate.type=warn
# log4j.logger.org.hibernate.persister.collection=DEBUG

# Spring

# log prepared statement cache activity ###
log4j.logger.org.hibernate.ps.PreparedStatementCache=info


###### Examples #######
# To dump performance results on VM termination
#log4j.logger.performance.summary.vm=debug

# To dump performance stats on every call
#log4j.logger.performance.summary.method=debug

# Examples of activating performance logging on various beans

错误信息 : WARN  [ehcache.config.ConfigurationFactory] No configuration found. Configuring ehcache from ehcache-failsafe.xml
解决方法 : 在WEB-INF/classes/路径下加上文件 ehcache.xml 其参考内容如下

<ehcache>
 <diskStore path="java.io.tmpdir"/>
 <defaultCache
    maxElementsInMemory="10000"
    eternal="false"
    timeToIdleSeconds="10000"
    timeToLiveSeconds="10000"
    overflowToDisk="true"
 />
  <cache  name="com.hour41.hibernate.vo.common.City"
    maxElementsInMemory="10000"
    eternal="false"
    timeToIdleSeconds="10000"
    timeToLiveSeconds="10000"
    overflowToDisk="true"
 />
</ehcache>

错误信息：java.lang.NoSuchMethodError: org.objectweb.asm.ClassVisitor.visit(IILjava/lang/String;Ljava/lang/String;[Ljava/lang/String;Ljava/lang/String;)V
at net.sf.cglib.core.ClassEmitter.begin_class(ClassEmitter.java:77)

解决方法：Spring 和 Hibernate 共用的一些 jar 文件发生了版本冲突, 删除 WEB-INF/lib/asm-2.2.3.jar 然后重启 Tomcat.


错误信息：javax.servlet.jsp.JspException: Invalid argument looking up property usersVO.account of bean loginForm
解决方法：Form中的usersVO没被实例化，在reset方法中new一下就OK了

错误信息：org.apache.jasper.JasperException: Failed to load or instantiate TagLibraryValidator class: org.apache.taglibs.standard.tlv.JstlCoreTLV
解决方法：加入standard.jar，重启tomcat

错误信息：严重: Exception loading sessions from persistent storage 
解决方法：tomcat安装目录\work\Catalina\localhost\{webAppName}\SESSIONS.ser，删除此文件
