我正在尝试使用JDBCAppender配置log4j来记录到数据库,参考以下链接。
http://logging.apache.org/log4j/2.x/manual/appenders.html#JDBCAppender
但是我收到错误"类型GenericObjectPool不接受参数"。有人可以帮我纠正这个错误吗?
log4j2.xml
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="error">

<JDBC name="databaseAppender" tableName="LOGGING.APPLICATION_LOG">

<Column name="EVENT_DATE" isEventTimestamp="true" />
<Column name="LEVEL" pattern="%level" />

问题已由我自己解决。
我添加了maven依赖,它对我来说很好。

<groupId>commons-pool</groupId>
