springboot使用的版本是2.1.4
shardingjdbc使用的版本是4.0.0-RC3
mysql-connector-java使用的版本是8.0.15
然后就疯狂报错Factory method 'shardingDataSource' threw exception; nested exception is java.lang.NumberFormatException: For input string: "YES"
具体报信息如下：

最主要是不管在百度还是google里根本搜不到相关的信息，我很绝望。。尝试看报错信息的源码也找不出什么原因。最后在github上看到有人提类似的问题，才找到问题所在。居然是版本的问题！！！
mysql-connector-java使用的版本是8.0.15的话，shardingjdbc就不能用4.0.0-RC3。。。
好吧，把shardingjdbc版本降为4.0.0-RC2就能正常启动了。
