Properties的load方法加载的文件格式要求

properties.load(new FileInputStream("C://prop.txt"));
properties.loadFromXML(new FileInputStream("C://prop.xml"));

Properties的这两个方法对于输入流是有格式要求的

load：

b=11
a=11
c=11

loadFromXML：

<?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd"><properties><comment>这是xml存储格式</comment><entry key="b">11</entry><entry key="a">11</entry><entry key="c">11</entry></properties>[/code]
