需要jar包
工具类:
package qingxia.tang.utils; import java.io.IOException; import java.io.InputStream; import java.util.Properties; import org.springframework.core.io.ClassPathResource; import org.springframework.core.io.Resource; public class Demo { private static Properties pro=new Properties(); static { Resource res=new ClassPathResource("upload.properties");//加载配置文件 InputStream isp=null; try { isp=res.getInputStream();//获取输入流 pro.load(isp); } catch (IOException e) { e.printStackTrace(); } finally { try { if(isp!=null) { isp.close(); } } catch (IOException e) { e.printStackTrace(); } } } public static String getValue(String key) { return pro.getProperty(key); } public static void main(String[] args) { String value = getValue("password"); System.out.println(value); } }
需将upload.properties放在根目录。
