使用ibatis开发Swing程序配置log4j显示ibatis的sql语句

   准备用swing做一个拨号程序，和数据库打交道的地方比较多，所以考虑用ibatis来和数据库交互，在搭框架的时候，调式程序时 sql语句没有被打印出来，所以决定用log4j打印出来，以方便调式。

  我使用的是netbeans6.0.1,在工程的根目录新建一个log4j.properties的文件，然后在里面加上配置：代码如下：

 

ibatis2.3 --log4j 写道

log4j.rootLogger=info,stdout
log4j.debug=true

#ibatis log configure
log4j.logger.com.ibatis=debug
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=debug
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=debug
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=debug
log4j.logger.java.sql.Connection=debug
log4j.logger.java.sql.Statement=debug
log4j.logger.java.sql.PreparedStatement=DEBUG

 注意这句话：

 

log4j.rootLogger=info,stdout 写道

log4j.rootLogger=info,stdout

 假如不加上这句话的话，那么log4j不会输入sql语句，但是会输入一些null，测试时控制台打印如下：

写道

log4j: Finished configuring.
log4j:WARN No appenders could be found for logger (com.ibatis.common.jdbc.SimpleDataSource).
log4j:WARN Please initialize the log4j system properly.

 只有加上了这句：log4j.rootLogger=info,stdout

 控制台才会输入sql语句：
