java获取properties文件中的值

方法一：
Properties props = new Properties();
try {
props.load(Thread.currentThread().getContextClassLoader().getResourceAsStream("upload.properties"));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
String test = props.getProperty("file_uploadPath");

方法二：
// properties 配置文件名称
ResourceBundle res = ResourceBundle.getBundle("upload");
String test = res.getString("file_uploadPath");
方法三：
import java.util.PropertyResourceBundle;

// properties 配置文件名称
PropertyResourceBundle res = (PropertyResourceBundle) PropertyResourceBundle.getBundle("ApplicationResources");
// 获取properties配置文件中的属性值
String ftpurl = res.getString("FtpUrl ");
