Mysql JDBC驱动程序ClassNotFoundException [英] Mysql JDBC driver ClassNotFoundException

问题描述

我无法在桌面APP中注册Mysql JDBC驱动程序

I can't register Mysql JDBC driver in my desktop APP

我下载了mysql-connector-java-5.1.16.zip

I download mysql-connector-java-5.1.16.zip

解压缩 mysql-connector-java-5.1.16-bin.jar ，并将其放入我应用程序的 lib 文件夹中

Unzip mysql-connector-java-5.1.16-bin.jar and put it into lib folder in my app

将此jar文件添加到Eclipse中的构建路径中

Add this jar file into Build Path in Eclipse

但是Class.forName("com.mysql.jdbc.Driver")抛出ClassNotFoundException

But Class.forName("com.mysql.jdbc.Driver") throws ClassNotFoundException

怎么了?

推荐答案

尝试一下:

public static void main(String[] args) throws Exception {
    Class.forName("com.mysql.jdbc.Driver");
}

问题在于Class.forName(String)引发一个已检查的异常.使用受检查的异常，您可以:

The issue is that Class.forName(String) throws an checked exception. With a checked exception, you can either:

1. 捕获异常.
2. 声明您的方法引发异常. (这是我上面建议的).

以下是捕获异常的示例:

Here is an example of catching the exception:

public static void main(String[] args) throws Exception {
    try {
        Class.forName("com.mysql.jdbc.Driver");
    } catch(ClassNotFoundException e) {
        //do some exception handling
    }
}
