java.lang.NullPointerException: Cannot invoke
"com.alibaba.druid.stat.JdbcDataSourceStat.getRuningSqlList()" because the
return value of "com.alibaba.druid.pool.DruidDataSource.getDataSourceStat()" is
null
原因:版本不一致出现。使用的是5.x.x的。
解决:改了就可以了(之前是5.x.x)
在mysql中执行SELECT VERSION()
mysql-connector-java版本需与mysql版本一致
<!--mysql驱动--> <dependency> <groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId> <version>8.0.27</version>
<scope>compile</scope> </dependency>
注意:检查数据库版本
com.mysql.jdbc.Driver 是 mysql-connector-java 5及5之前的,
com.mysql.cj.jdbc.Driver 是 mysql-connector-java 6及6之后的的。
