打开以前的旧项目,启动时出现的异常信息:java.sql.SQLException: Unable to load authentication plugin 'caching_sha2_password'.处理办法升级pom.xml中依赖mysql依赖包版本。
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.21</version> </dependency><!--旧写法-->
<dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.11</version> </dependency> <!--新版本-->
修改后再次启动项目,再次报异常
InvalidConnectionAttributeException: The server time zone value '???ú±ê×??±??' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the serverTimezone configuration property) to use a more specifc time zone value if you want to utilize time zone support.
处理办法:
db连接上添加serverTimezone=UTC
jdbc.url=jdbc:mysql://localhost:3306/mzwm?characterEncoding=utf8&&serverTimezone=UTC
