在java中读取属性文件时发生文件未找到错误

Question

i create the property file under package of resources/common/configure/

then i create the code

    Properties prop = new Properties();

    try {
           //load a properties file
        prop.load(new FileInputStream("resources/common/configure/commonData.properties"));

           //get the property value and print it out
            System.out.println(prop.getProperty("id"));


    } catch (IOException ex) {
        ex.printStackTrace();
    }

but i got the following error

java.io.FileNotFoundException: (The system cannot find the path specified)

please let me know how can i get this property file.

Answer 1

试试吧

prop.load(getClass().getResourceAsStream("resources/common/configure/commonData.properties"));

Answer 2

The program tries to find the "commonData.properties" at a path specified relative to where you are running it. Providing a correct relative path or full path of configuration file might solve the issue.

Answer 3

Use absolute file paths. Print the full path and you'll be able to spot your problem.

Alternatively, use getClass().getResourceAsStream() .
