java代码中利用map将从文件中读取的内容缓存起来 + 从属性文件中读内容放入hashmap中 + 判断是否有汉字、是否字符 +

    public static String getContent(String requestPage) throws IOException {
        try {
            String contentPage = (String) cacheContent.get(requestPage);
            if (contentPage == null) {
                String templatePath = AwsResourceReader.in.getString(requestPage);
                BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(templatePath), SpecialCharacterEncoding.CHINESE_ENCODING)); // 070827
                StringBuffer content = new StringBuffer();
                String line = br.readLine();
                while (line != null) {
                    content.append(line);
                    content.append("\n");
                    line = br.readLine(); 
                }
                br.close();
                contentPage = content.toString();    
                cacheContent.put(requestPage, contentPage);
            }return contentPage;
        } catch (IOException ioe) {
            Logger.logError("ContentPageReader getContent() Exception " + ioe);
            throw ioe;}   

 从.properties文件中读取内容，放入hashmap中

new Integer(AwsResourceReader.in.getInt("Customer.customer_per_page"));
public static final GenericResourceReader in = new AwsResourceReader("AwsResources_en_MY");
	FileInputStream fis = new FileInputStream(file);
  ResourceBundle resourceBundle = new PropertyResourceBundle(fis);
	Properties properties = new Properties();
	Properties.load(stream);
	Map lookup = new HashMap(properties);
  resourceBundle = ResourceBundle.getBundle(baseName, locale);

 是否含有汉字

    private static boolean hasChineseCharacter(String ms950String) {
        for (int i=0; i< ms950String.length(); i++) {
            int ascii = (int) ms950String.charAt(i);
            if ((int)ms950String.charAt(i) >= 256) {
                return true;
            }
        }
        return false;
    }

 是否是字符

//是否是字符 --sample--
public static boolean isAlpha(String input, boolean allowNull, boolean allowSpace) {
    boolean result = true;
    if (isEmptyString(input)) {
        result = allowNull;
    } else {
        for (int i = 0; i < input.trim().length(); i++) {
            char c = input.charAt(i);
            if (!Character.isLetter(c)) {
                if (c == ' ') {
                    result = allowSpace;
                } else {
                    result = false;
                }
            }
        }
    }
    return result;
}
