经过修改的读取配置文件PROPERTIES的小工具，对象尽量创建一次
package com.opzoon.app.airchina.util;
import java.io.File;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;
public class ConfigUtil {
private final static Properties prop = new Properties();
private static ConfigUtil instance;
private ConfigUtil() {
InputStream is=null;
is=this.getClass().getClassLoader().getResourceAsStream("conf"+File.separator+"config.properties");
if (null!=is) {
try {
prop.load(is);
} catch (IOException e) {
e.printStackTrace(System.err);
} catch (Exception ex) {
ex.printStackTrace(System.err);
}
finally {
try {
if(null!=is) {
is.close();
is=null;
}
}catch(IOException e) {
e.printStackTrace();
}
}
} else {
System.out.println("无法找到配置文件：");
}//end if -else
}
public String getProperty(String key) {
String value;
if (prop.containsKey(key)) {
value = (String) prop.get(key);
} else {
value = "";
}
return value;
}
public static ConfigUtil getInstance(){

System.out.println("xxxxxLOCAL_PATH="+new ConfigUtil().getProperty("FTP_PATH"));
}
