maven项目整合SSM配置log4j, 实现控制台打印SQL语句

在原有项目正常启动的情况下, 实现在控制台打印mapper包下SQL语句.

1.在pom.xml配置文件中添加两个依赖(缺一不可)

        <!--日志包-->
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>${log4j-version}</version>
        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
            <version>${slf4j-version}</version>
        </dependency>    

版本:

<log4j-version>1.2.17</log4j-version>
<slf4j-version>1.7.25</slf4j-version>

2. 在log4j.properties配置文件中添加配置

log4j.logger.com.zzuli.mapper=DEBUG

完整的log4j.properties

log4j.rootCategory=ERROR, CONSOLE ,LOGFILE

log4j.logger.com.zzuli.mapper=DEBUG

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%C %d{YYYY-MM-dd hh:mm:ss}  %m %n

log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=E:/my.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%m %n

配置完以上两项, 即可实现在控制台打印SQL语句.

完.
