MyBatis + Druid 启动批量SQL功能

Mysql 连接字符串新增

&allowMultiQueries=true

Druid配置修改

#因为wall会导致无法批量更新，所以这里不配置wall，改为在DruidDataSourceConfig 里面配置支持批量更新的wall
#spring.datasource.druid.filters=stat,wall,config
spring.datasource.druid.filters=stat,config

DruidConfig类中修改

package com.java.core.mapper.config;


import com.alibaba.druid.filter.Filter;
import com.alibaba.druid.pool.xa.DruidXADataSource;
import com.alibaba.druid.wall.WallConfig;
