首先通过下面的类获取Properties：

import java.util.Properties;
import java.io.IOException;
import java.io.InputStream;
//import org.apache.commons.logging.LogFactory;
public class Configuration {
private static Properties props = null;
private static InputStream input = null;
public static String getProperty(String key){
  if(props==null)
   initProperties();
  return props.getProperty(key);
}
public static void initProperties() {
  props = new Properties();
  try {
   if (props.size() == 0) {
    input = Configuration.class.getClassLoader()
      .getResourceAsStream("application.properties");

    props.load(input);
   }
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } finally {
   try {
    if (input != null) {

input.close();

     input = null;
    }
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
  }
}
}

然后：通过 Configuration.getProperty("svc.url");获取参数内容

import com.common.util.Configuration;
public class Test {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println(Configuration.getProperty("svc.url"));
}
}

application.properties内容格式：

svc.url=http://10.109.17.20:8888/svcBiz-webservice/ForSVCService
