一个新手关于LOG4J连数据库的问题,请高手解答,万分感谢!
我学习建立一个在线教育工程(eclipse+tomcat)的日志系统,我用的log4j记录日志,现在在把日志输到MYSQL数据库中出了问题.
我的LOG4J的properties配置如下:
###########################################
log4j.rootCategory=INFO,DatabaseApp
log4j.appender.DatabaseApp=org.apache.log4j.jdbc.JDBCAppender
log4j.appender.DatabaseApp.URL=jdbc:mysql://localhost:3306/test
log4j.appender.DatabaseApp.driver=com.mysql.jdbc.Driver
log4j.appender.DatabaseApp.user=root
log4j.appender.DatabaseApp.password=
log4j.appender.DatabaseApp.layout=org.apache.log4j.PatternLayout
log4j.appender.DatabaseApp.layout.ConversionPattern=INSERT INTO log4j (createDate,thread,priority,category,message) values(getdate(),'%t','%-5p','%c','%m')
#############################################################
我装的是MYSQL5.0,从MYSQL网上下了最新的 mysql-connector-java-5.0.0-beta.zip
因为不知道把它配到哪,我在 CLASSPATH 放了F:\Java\mysql-connector-java-5.0.0-beta\mysql-connector-java-5.0.0-beta-bin.jar;F:\Java\mysql-connector-java-5.0.0-beta\debug\mysql-connector-java-5.0.0-beta-bin-g.jar;
并在eclipse下工程中添加外部的JAR包F:\Java\mysql-connector-java-5.0.0-beta\mysql-connector-java-5.0.0-beta-bin.jar;F:\Java\mysql-connector-java-5.0.0-beta\debug\mysql-connector-java-5.0.0-beta-bin-g.jar;
我在MYSQL也建好了名叫log4j的表
create table log4j
(createDate varchar(20),
thread varchar(20),
priority varchar(20),
caregory varchar(20),
message varchar(40),
primary key(createDate)
)
-----------------------------------------------------------------
运行工程后出现错误

请问怎么解决这个问题,另说明一下;
1.我用mysql-connector-java-3.1.12.zip也试过,不行.
2.我LOG4J写到普通文本可以成功.
是不是哪里配置错误?
