This error message usually occurs when the JDBC driver for MySQL is not found or not properly configured in your
Java application. To fix this issue, you need to make sure that you have the correct JDBC driver for MySQL installed and that the driver is included in your application’s classpath. Here are some steps you can follow to resolve this issue: 1. Download the JDBC driver for MySQL from the official
website: https://dev.mysql.com/downloads/connector/j/ 2. Extract the downloaded ZIP file and copy the JAR file to a folder in your project directory. 3.
Add the JDBC driver JAR file to your project’s classpath. You can do this by
adding the following line to your project’s build file (e.g. pom.xml for Maven): <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-
java</artifactId> <version>8.0.23</version> idea添加框架支持 </dependency> 4. Make sure that you are using the correct JDBC URL for your MySQL database. The format should be like this: jdbc:mysql://localhost:3306/your_database_name Replace “your_database_name” with the actual name of your MySQL database. 5. Check that your MySQL database is running and accessible from your
Java application. You can test this by using a MySQL client tool (e.g. MySQL Workbench) to connect to the database using the same credentials that your
Java application is using. Once you have verified that the JDBC driver is installed and configured correctly, and that your MySQL database is running and accessible, you should be able to connect to the database from your
Java application without any issues.今天的文章
