java.lang.ClassNotFoundException: Cannot find class: “com.mysql.jdbc.Driver“的报错问题

@Test
public void testConnectionTest5() throws Exception {
    //1.读取配置文件，获取4个基本信息
    InputStream is = ConnectionTest.class.getClassLoader().getResourceAsStream("jdbc.properties");
    Properties pros =  new Properties();
    pros.load(is);

    String DRIVER = pros.getProperty("DRIVER");
    String URL = pros.getProperty("URL");
    String USER = pros.getProperty("USER");
    String PWD = pros.getProperty("PWD");

    //2.加载驱动
    Class.forName(DRIVER);

    //3.获取连接
    Connection conn = DriverManager.getConnection(URL,USER,PWD);
    System.out.println(conn);
}

运行时一直报错，为了解决这个问题我四处奔波啊，百度了各种方法，最终发现是因为properties中属性赋值时等于号后面都加了引号，把配置文件中的引号去掉即可

配置文件中的信息
URL=jdbc:mysql://localhost:3306/fruitdb?useUnicode=true&characterEncoding=utf-8&useSSL=false
USER=
PWD=
DRIVER=com.mysql.jdbc.Driver
