java 讀取properties文件

 

import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class GetProperties {
    public static void main(String[] args) throws IOException {
        Properties p = new Properties();
        InputStream in = GetProperties.class
                .getResourceAsStream("/config.properties");

        p.load(in);
        in.close();
        System.out.println(p.getProperty("ip"));
    }
}

 

javaweb工程編譯後，config.properties在classes文件夾下
