Mybats 抖动慢

Question

我的项目执行 sql 非常慢，每个 sql 成本超过 3 second.There 在我的数据库中数据很少。
我尝试了多种变体，但其中 none 似乎有效。有任何想法吗？

配置

springboot1.3.1
mybatis3.2.8
德鲁伊1.0.16。

找到问题了，这个项目使用了logback，把日志发给ELK，但是ELK的redis服务挂了。

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <property name="AppName" value="Docx"/>

    <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>${AppName} %d %-5p [%thread] %c:%L - %m%n</pattern>
        </encoder>
    </appender>

    <appender name="logstash" class="com.cwbase.logback.RedisAppender">
        <source>*</source>
        <type>*</type>

        <location>true</location>
        <callerStackIndex>0</callerStackIndex>
        <level>INFO</level>
    </appender>

    <appender name="errorFile"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>logs/error/error</File>
        <encoder>
            <pattern>%d [%thread] %c:%L-%m%n</pattern>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>logs/error/error_%d{yyyy-MM-dd}</fileNamePattern>
        </rollingPolicy>

        <!-- <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>DEBUG</level>

            <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> -->
    </appender>

    <appender name="sqlFile"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <File>logs/sql/slow</File>
        <encoder>
            <pattern>%d [%thread] %c:%L-%m%n</pattern>
        </encoder>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>logs/sql/slow_%d{yyyy-MM-dd}</fileNamePattern>
        </rollingPolicy>
    </appender>
    <logger name="com.alibaba.druid.filter.stat.StatFilter" additivity="false" level="DEBUG">
        <appender-ref ref="sqlFile"/>
    </logger>



    <logger name="org" level="ERROR"/>

    <root level="DEBUG">
        <appender-ref ref="stdout"/>
<!--        <appender-ref ref="logstash"/>-->
    </root>


</configuration>

注释后<appender-ref ref="logstash"/>，正常工作
