druid，log4j记录sql，发现会执行三次，

解决没有啊？求分享一下，

应该是log4j配置的问题吧

#druid日志
log4j.logger.druid.sql=error,appendConsole
log4j.logger.druid.sql.DataSource=error,appendConsole
log4j.logger.druid.sql.Connection=error,appendConsole
log4j.logger.druid.sql.Statement=debug,appendConsole

log4j.logger.druid.sql.ResultSet=error,appendConsole

我是这么配的

是不是同时配置了filter和proxyFilters

#过滤   如果同时配置了filters和proxyFilters，是组合关系，并非替换关系
#filters:config

建议在properties就配置个filters:config,用来加密数据库连接密码。然后在datasource里配置

<!-- 配置监控统计拦截的filters -->
<property name="proxyFilters">
<list>
<ref bean="stat-filter" />
<ref bean="wall-filter" />
<ref bean="log-filter" />
</list>
</property>

把配置以发出来

要druid配置

先把log中druid的配置去了试试

同求解决办法

把log4j里面的配置删除，spring里面配置的filter有log类型就可以了，还有就是sql不是执行了3次，而是打印了3遍
