New MySQL driver causes java.sql.SQLNonTransientConnectionException: CLIENT_PLUGIN_AUTH is required
提问by Dims
If change MySQL JDBC driver from 5.1.38to 6.0.2I get the following exception
如果将 MySQL JDBC 驱动程序从 更改5.1.38为6.0.2我得到以下异常
java.sql.SQLNonTransientConnectionException: CLIENT_PLUGIN_AUTH is required
This exception was happened in normal JDBC initilization.
此异常发生在正常的 JDBC 初始化中。
Probably, this can be related with SSL, since I get the following messages also
可能，这可能与 SSL 相关，因为我也收到以下消息
Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
不建议在没有服务器身份验证的情况下建立 SSL 连接。根据 MySQL 5.5.45+、5.6.26+ 和 5.7.6+ 要求，如果未设置显式选项，则必须默认建立 SSL 连接。为了符合不使用 SSL 的现有应用程序，verifyServerCertificate 属性设置为“false”。您需要通过设置 useSSL=false 来显式禁用 SSL，或者设置 useSSL=true 并为服务器证书验证提供信任库。
which were absent in previous version.
在以前的版本中没有。

This sounds like a regression. Was there a particular reason to switch to 6.0.2? If not, I'd revert back to 5.1.38 and give 6.x a shot after three months to let folks at MySQL to stabilize the driver.
这听起来像是一种回归。切换到 6.0.2 是否有特殊原因？如果没有，我会恢复到 5.1.38 并在三个月后尝试 6.xa，让 MySQL 的人稳定驱动程序。

It seems new versions of mysql connector(from 6 on)are not compatible with old version of the DBMS mysql(below 5.6). So in order to solve your problem, if you make an update of mysql connector, try to do the same with the DBMS. Actually I had the same issu with mysql connector 8.0.13and the DBMS msql 5.1....I solved it by moving the DBMS to 5.6.17
似乎新版本的mysql 连接器（从 6 开始）与旧版本的DBMS mysql（低于 5.6）不兼容。因此，为了解决您的问题，如果您更新mysql 连接器，请尝试对DBMS执行相同操作。实际上，我对mysql 连接器 8.0.13和DBMS msql 5.1有相同的问题......我通过将DBMS 移至 5.6.17解决了这个问题
