mybatisplus-批量更新

1.<update id="updateBatch" parameterType="java.util.List">
    <foreach collection="list" item="item" index="index" separator=";">
        UPDATE enterprise_oil_adjust_record
        SET next_enterprise_price = #{item.nextEnterprisePrice}
        WHERE
        batch_no = #{item.batchNo} 
    </foreach>

</update>

2.sql连接添加

&allowMultiQueries=true

3.数据源

//Druid配置的时候还有一个大坑就是，不要同时配置filters和proxyFilters，filter都是内置的，想通过proxyFilters来定制的话，就不要配置filters
datasource.setConnectionProperties(dataSourceProperties.getConnectionProperties());

WallConfig wallConfig=new WallConfig();
wallConfig.setMultiStatementAllow(true);
WallFilter wallFilter = new WallFilter();
wallFilter.setConfig(wallConfig);
List<Filter> filters = new ArrayList<>();
filters.add(wallFilter);
datasource.setProxyFilters(filters);
