BufferedReader in = new BufferedReader(new InputStreamReader(inStream, "8859_1")); 我们只去掉后面规定的那个编码就可以实现平台相关的编码方式，为了避免直接修改源代码，我们重新定义一个类，例如：
package org.jr.util;import java.util.*;import java.io.*;public class Properties extends java.util.Properties { private static final String keyValueSeparators = "=: f"; private static final String strictKeyValueSeparators = "=:"; private static final String specialSaveChars = "=: f#!"; private static final String whiteSpaceChars = " f"; public synchronized void load(InputStream inStream) throws IOException { BufferedReader in = new BufferedReader(new InputStreamReader(inStream)); while (true) { // Get next line String line = in.readLine(); if (line == null) { return; } if (line.length() > 0) { // Continue lines that end in slashes if they are not comments char firstChar = line.charAt(0); if ( (firstChar != ´#´) && (firstChar != ´!´)) { while (continueLine(line)) { String nextLine = in.readLine(); if (nextLine == null) { nextLine = ""; } String loppedLine = line.substring(0, line.length() - 1); // Advance beyond whitespace on new line int startIndex = 0; for (startIndex = 0; startIndex < nextLine.length(); startIndex++) { if (whiteSpaceChars.indexOf(nextLine.charAt(startIndex)) == -1) { break; } } nextLine = nextLine.substring(startIndex, nextLine.length()); line = new String(loppedLine + nextLine); } // Find start of key int len = line.length(); int keyStart; for (keyStart = 0; keyStart < len; keyStart++) { if (whiteSpaceChars.indexOf(line.charAt(keyStart)) == -1) { break; } } // Blank lines are ignored if (keyStart == len) { continue; } // Find separation between key and value int separatorIndex; for (separatorIndex = keyStart; separatorIndex < len; separatorIndex++) { char currentChar = line.charAt(separatorIndex); if (currentChar == ´/´) { separatorIndex++; } else if (keyValueSeparators.indexOf(currentChar) != -1) { break; } } // Skip over whitespace after key if any int valueIndex; for (valueIndex = separatorIndex; valueIndex < len; valueIndex++) { if (whiteSpaceChars.indexOf(line.charAt(valueIndex)) == -1) { break; } } // Skip over one non whitespace key value separators if any if (valueIndex < len) { if (strictKeyValueSeparators.indexOf(line.charAt(valueIndex)) != -1) { valueIndex++; // Skip over white space after other separators if any } } while (valueIndex < len) { if (whiteSpaceChars.indexOf(line.charAt(valueIndex)) == -1) { break; } valueIndex++; } String key = line.substring(keyStart, separatorIndex); String value = (separatorIndex < len) ? line.substring(valueIndex, len) : ""; // Convert then store key and value key = loadConvert(key); value = loadConvert(value); put(key, value); } } } } /* * Returns true if the given line is a line that must * be appended to the next line */ private boolean continueLine (String line) { int slashCount = 0; int index = line.length() - 1; while((index >= 0) && (line.charAt(index--) == ´/´)) slashCount++; return (slashCount % 2 == 1); } /* * Converts encoded /uxxxx to unicode chars * and changes special saved chars to their original forms */ private String loadConvert (String theString) { char aChar; int len = theString.length(); StringBuffer outBuffer = new StringBuffer(len); for(int x=0; x<len; ) { aChar = theString.charAt(x++); if (aChar == ´/´) { aChar = theString.charAt(x++); if(aChar == ´u´) { // Read the xxxx int value=0; for (int i=0; i<4; i++) { aChar = theString.charAt(x++); switch (aChar) { case ´0´: case ´1´: case ´2´: case ´3´: case ´4´: case ´5´: case ´6´: case ´7´: case ´8´: case ´9´: value = (value << 4) + aChar - ´0´; break; case ´a´: case ´b´: case ´c´: case ´d´: case ´e´: case ´f´: value = (value << 4) + 10 + aChar - ´a´; break; case ´A´: case ´B´: case ´C´: case ´D´: case ´E´: case ´F´: value = (value << 4) + 10 + aChar - ´A´; break; default: throw new IllegalArgumentException( "Malformed /uxxxx encoding."); } } outBuffer.append((char)value); } else { if (aChar == ´t´) aChar = ´ ´; else if (aChar == ´r´) aChar = ´
