mysql版本和mysql-connector-java版本问题_mysql-connector-java 8.0.30

问题：Failed to obtain JDBC Connection; nested exception is java.sql.SQLNonTransientConnectionException: CLIENT_PLUGIN_AUTH is required

 我的mysql版本

 未指定版本前，mysql-connector-java的版本是8.0.30

 在pom文件中将mysql-connector-java降版本

<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.0.8</version>
</dependency>

 降版本后遇到com.mysql.jdbc.Connection.isValid(I)Z 

这是因为mysql的jar包版本过低,需要更新到新版mysql的jar包.

再提高到5.1.49

<dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.49</version>
            <scope>runtime</scope>
</dependency>

 成功：
