Druid数据源 sql injection violation, multi-statement not allow

问题描述：

Error updating database.  Cause: java.sql.SQLException: sql injection violation, multi-statement not allow : update data set layer = ? where time = ? and id=?

解决方案：
1.数据源url

spring.datasource.druid.url=jdbc:mysql://ip:3306/db?allowMultiQueries=true&useSSL=false&serverTimezone=Asia/Shanghai

2. spring.datasource.filters的参数设置 wall

WallFilter () {
    WallFilter wallFilter = WallFilter()wallFilter.setConfig(())wallFilter}

WallConfig () {
    WallConfig config = WallConfig()config.setMultiStatementAllow()config.setNoneBaseStatementAllow()config}
buildDruidDataSource 中增加： 
List<Filter> filterList = Lists.newArrayList(wallFilter());
druidDataSource.setProxyFilters(filterList);
