要借助Log4j分析MyBatis的执行计划,可以按照以下步骤操作:
<configuration>
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %p [%c] - %m%n" />
</layout>
</appender>
<logger name="org.apache.ibatis" additivity="false">
<level value="DEBUG" />
<appender-ref ref="console" />
</logger>
<root>
<priority value="INFO" />
<appender-ref ref="console" />
</root>
</configuration>
import org.apache.ibatis.logging.Log;
import org.apache.ibatis.logging.LogFactory;
public class MyBatisExecutor {
private static final Log logger = LogFactory.getLog(MyBatisExecutor.class);
public void execute() {
logger.debug("Start executing MyBatis query");
// 执行MyBatis查询操作
logger.debug("Finish executing MyBatis query");
}
}
通过上述步骤,你可以借助Log4j分析MyBatis的执行计划,帮助优化查询性能和调试SQL语句问题。
