Java使用properties读取配置文件

public class ReadProperties {

public static Properties getPro() {
Properties property = new Properties();
try {
property.load(ReadProperties.class.getClassLoader()
.getResourceAsStream("mailProperty.properties"));//properties文件名
} catch (IOException e) {
e.printStackTrace();
}
return property;
}

public static void main(String [] args){

Properties property = ReadProperties.getPro();
String mailServerHost = property.getProperty("MailServerHost");
String mailServerPort = property.getProperty("MailServerPort");

System.out.println(mailServerHost);
System.out.println(mailServerPort);
}
}

# This file contains my default Mail properties.
MailServerHost = smtp.163.com
MailServerPort = 25
