为什么 mybatis 强制将 log4j DEBUG 信息打印到控制台

Question

我已经将 mybatis 配置为使用 log4j 进行日志记录。我将 log4j 配置为仅打印警告信息。但是当我运行它时，mybatis 会向控制台打印很多 sql 调试消息：

<http-bio-80-exec-1 10:08:54,969> <org.apache.ibatis.logging.jdbc.BaseJdbcLogger:139> DEBUG - ==>  Preparing: select count(*) from accounts 
<http-bio-80-exec-1 10:08:54,993> <org.apache.ibatis.logging.jdbc.BaseJdbcLogger:139> DEBUG - ==> Parameters: 
<http-bio-80-exec-1 10:08:55,093> <org.apache.ibatis.logging.jdbc.BaseJdbcLogger:139> DEBUG - <==      Total: 1

mybatis.xml 文件：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//xml.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <settings>
        <setting name="logImpl" value="LOG4J"/>
    </settings>
</configuration>

PS：我正在使用 intellij IDEA

Answer 1

我自己解决了这个问题 我应该在配置文件中添加log4j.logger.my_package.mapper=LOG_LEVEL

Answer 2

您忘记了log4j.properties 中最后一个属性前面的log4j.logger。
