初学Hibernate中出现的一些错误

错误一：JDBC Driver class not found:com.microsoft.sqlserver.jdbc.SQLServerDriver

解决方法:在/WEB-INF/lib目录下导入sqljdbc.jar

错误二:

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

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
