JAR文件如何读取外部属性文件

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;

public class JarFileReader {
    public static void main(String[] args) {
        String jarFilePath = "path/to/your/jar/file.jar";
        String propertyFilePath = "config.properties";

        try (JarFile jarFile = new JarFile(jarFilePath)) {
            JarEntry entry = jarFile.getEntry(propertyFilePath);
            if (entry != null) {
                try (InputStream inputStream = jarFile.getInputStream(entry)) {
                    Properties properties = new Properties();
                    properties.load(inputStream);

                    String value = properties.getProperty("key");
                    System.out.println("Value: " + value);
                }
            } else {
                System.out.println("Property file not found in the JAR file.");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
