为什么我的 Java 应用程序中出现“没有找到适合 MySQL 的驱动程序”错误？

SQLException: No suitable driver found for MySQL

Problem:

You are receiving a "No suitable driver found for MySQL" error when trying to connect to a MySQL database using JDBC in a Java application.

Possible Causes:

• JDBC driver is not loaded.
• URL for database connection does not match any loaded JDBC drivers.
• URL format is incorrect.

Solution:

1. Load the JDBC Driver:

   Make sure the MySQL JDBC driver is included in your project's classpath. Add the mysql-connector-java JAR file to the /WEB-INF/lib directory of your web application.

2. Check the URL Format:

   Verify that the URL you are using to connect to the database matches the correct format for MySQL:

   jdbc:mysql://localhost:3306/database_name

   Where:

   • localhost is the hostname or IP address of the MySQL server.
   • 3306 is the default port for MySQL.
   • database_name is the name of the database you wish to connect to.

3. Throw Exceptions Properly:

   Instead of printing the error message and continuing with the code, throw the exception to prevent further execution.

Additional Tips:

• Consider using a dependency management tool like Maven or Gradle to automatically download and include the necessary JAR files.

Unrelated Issues:

• Java code should not be placed in JSP files.
• Improve exception handling by throwing instead of printing.
