java.io.FileNotFoundException:解决方法

运行如下代码会出现 java.io.FileNotFoundException:D:\\IDEA%20Workspace\\out\\production\\day04_JDBC\\jdbc.properties (系统找不到指定的路径。)

```java public class test { public static void main(String[] args) { try { //1.创建properties集合类 Properties properties = new Properties(); //获取src路径下的文件的方式--->ClassLoader 类加载器 ClassLoader classLoader = JDBCUtils.class.getClassLoader(); //jdbc.properties 绝对路径：D:\\\\IDEA Workspace\\\\CZHM\\\\JavaWeb\\\\day04_JDBC\\\\src\\\\jdbc.properties URL resource = classLoader.getResource("jdbc.properties"); String path = resource.getFile(); // /D:/IDEA%20Workspace/out/production/day04_JDBC/jdbc.properties System.out.println(path); //2. 加载文件 // pro.load(new FileReader("D:\\\\IdeaProjects\\\\CZHM\\\\day04_jdbc\\\\src\\\\jdbc.properties")); properties.load(new FileReader(path)); // properties.load(new FileReader("D:\\\\IDEA Workspace\\\\CZHM\\\\JavaWeb\\\\day04_JDBC\\\\src\\\\jdbc.properties")); //3. 获取数据，赋值 String url = properties.getProperty("url"); String user = properties.getProperty("user"); String password = properties.getProperty("password"); String driver = properties.getProperty("driver"); System.out.println(url); System.out.println(user); System.out.println(password); System.out.println(driver); Class.forName(driver); } catch (ClassNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }

解决办法：

String path = resource.getFile(); //添加如下代码 path = java.URLDecoder.decode(path, "utf-8");

即可解决
