Java.sql.SQLException:com.mysql.jdbc.Driver

The project was originally an Oracle driver + Druid data source configuration and is now being modified to MYSQL+DRUID data source configuration

When you start the project, report: Java.sql.SQLException:com.mysql.jdbc.Driver

The reason for the error is that there is no MySQL-driven jar in the project, and the JDBC-to-MySQL jar is missing.

Pom.xml, add the MySQL-driven jar

<Dependency>   <groupId>Mysql</groupId>   <Artifactid>Mysql-connector-java</Artifactid>   <version>5.1.38</version></Dependency>

Re-compile it.
