解决办法：
修改配置文件：的value值为1000。配置如下
<bean id="sqlSessionFactory" class="com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="databaseIdProvider" ref="databaseIdProvider" /> <property name="plugins"> <array> <bean id="paginationInterceptor" class="com.baomidou.mybatisplus.extension.plugins.PaginationInterceptor"> <property name="dialectType" value="mysql" /> </bean> <bean id="performanceInterceptor" class="com.baomidou.mybatisplus.extension.plugins.PerformanceInterceptor" > <property name="maxTime" value="1000" /> <property name="format" value="true" /> </bean> </array> </property> </bean>转载请注原文地址： https://blog.csdn.net/java_jack1/article/details/96429002
