SpringBoot+Mybatis logback不打印SQL解决方案

最近项目，由于测试提出需要将日志按天滚动日志，所以用了logback,日志打印工具。

但是由于使用了mybatis-config.xml 一直不打印SQL。最后将

<setting name="logImpl" value="STDOUT_LOGGING" />

这行注释，并且在application.properties里添加

logging.level.com.**.**.**.schedule.mapper=DEBUG

就可以了，以下是完整的配置。

mybatis-config.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <properties>
        <property name="dialect" value="mysql"/>
    </properties>
    <settings>
        <!-- 开启驼峰匹配 -->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
        <!-- 这个配置使全局的映射器启用或禁用缓存。系统默认值是true，设置只是为了展示出来 -->
        <setting name="cacheEnabled" value="true"/>
        <!-- 全局启用或禁用延迟加载。当禁用时，所有关联对象都会即时加载。 系统默认值是true，设置只是为了展示出来 -->
        <setting name="lazyLoadingEnabled" value="true"/>
        <!-- 允许或不允许多种结果集从一个单独的语句中返回（需要适合的驱动）。 系统默认值是true，设置只是为了展示出来 -->
        <setting name="multipleResultSetsEnabled" value="true"/>
        <!--使用列标签代替列名。不同的驱动在这方便表现不同。参考驱动文档或充分测试两种方法来决定所使用的驱动。 系统默认值是true，设置只是为了展示出来 -->
        <setting name="useColumnLabel" value="true"/>
        <!--允许 JDBC 支持生成的键。需要适合的驱动。如果设置为 true 则这个设置强制生成的键被使用，尽管一些驱动拒绝兼容但仍然有效（比如
            Derby）。 系统默认值是false，设置只是为了展示出来 -->
        <setting name="useGeneratedKeys" value="false"/>
        <!--配置默认的执行器。SIMPLE 执行器没有什么特别之处。REUSE 执行器重用预处理语句。BATCH 执行器重用语句和批量更新 系统默认值是SIMPLE，设置只是为了展示出来 -->
        <setting name="defaultExecutorType" value="SIMPLE"/>
        <!--设置超时时间，它决定驱动等待一个数据库响应的时间。 系统默认值是null，设置只是为了展示出来 -->
        <setting name="defaultStatementTimeout" value="25000"/>

        <setting name="callSettersOnNulls" value="true"/> <!-- 返回空字段 -->

        <!-- 打印查询语句 -->
<!--         <setting name="logImpl" value="STDOUT_LOGGING" />-->
    </settings>

    <!-- 分页助手 -->
      <plugins>
          <plugin interceptor="com.github.pagehelper.PageHelper">
              <!-- 数据库方言 -->
              <property name="dialect" value="mysql" />
              <property name="offsetAsPageNum" value="true" />
              <!-- 设置为true时，使用RowBounds分页会进行count查询 会去查询出总数 -->
              <property name="rowBoundsWithCount" value="true" />
              <property name="pageSizeZero" value="true" />
              <property name="reasonable" value="true" />
          </plugin>
      </plugins>
</configuration>
