MAP定义方法通过key获取value值

	String tablename=getTableName("XWSD");
	private static Map<String, String> TableNameMap = new HashMap<String, String>();
	private String getTableName(String type) {
		if (TableNameMap.size() == 0) {
			TableNameMap.put("XWSD", "tlk_p_news");
			TableNameMap.put("YDTD", "tlk_p_readwrold");
