How to add a .jar file to webserver's lib directory?
问题
我在执行需要com.mysql.jdbc.Driver的代码时遇到问题。尽管在项目结构中有mysql-connector-java-5.1.25-bin.jar（我正在运行基于Gradle的Spring Boot应用程序，并尝试将其连接到本地托管的XAMMP上的MySQL数据库），但当我执行代码时，我收到ClassNotFoundException。我在这里阅读了一些类似的帖子，人们说mysql-connector-java-5.1.25-bin.jar还应该添加到web服务器的lib目录中。我不知道在哪里找到它，或者如何做，因为我对Java和处理.jar文件还不太熟悉。
下面是异常信息。
这是我的代码。
英文:
I am having an issue when executing code which requires the com.mysql.jdbc.Driver. Although I have the mysql-connector-java-5.1.25-bin.jar in my Project Structure (I am running a Gradle-based, Spring Boot application and I am trying to connect it to a locally hosted MySQL database on XAMMP) when I execute the code I am getting a ClassNotFoundException. I have read up on some similar threads here and people say that the mysql-connector-java-5.1.25-bin.jar should also be added to the webserver's lib directory. I have no clue where to find it, or how to do it at all because I am kinda new to java and handling .jar files.
Below you will find the exception.
Here is my code.

如果您使用的是 SpringBoot 应用程序和 Maven，则需要在您的 pom.xml 文件中添加以下依赖：
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.49</version>
</dependency>
或者如果您使用的是 Gradle，则需要在您的 build.gradle 文件中添加以下依赖：
compile "mysql:mysql-connector-java:5.1.49"
英文:
If you are using a SpringBoot application and maven, you need to add to your pom.xml this dependency:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.49</version>
</dependency>
Or if you use the gradle, you need to add the dependency to your build.gradle file:
compile "mysql:mysql-connector-java:5.1.49"
