(1)使用matches方法快速建设是否表示给定的输入字符串:Pattern.matches("\\d","1")返回true (2)split(string)使用方法:Pattern.compile(":").split("one:two:three:four:five"); 返回:解析出“one two three four five”单词 再比如使用数字作为一个分割字符串的方法:(注意下面的\\d不是正则表达式,而是前面加了一个转义符号\) Pattern.compile("\\d").split("one9two4three7four1five");也返回相同的结果。。 (3)在String类中有的几个与Pattern类似的方法: public boolean matches(String regex): public String[] split(String regex, int limit): public String[] split(String regex): public String replace(CharSequence target,CharSequence replacement): (4) Matcher 类中其他一些有用的方法 索引方法 索引方法(index methods)提供了一些正好在输入字符串中发现匹配的索引值: public int start():返回之前匹配的开始索引。 public int start(int group):返回之前匹配操作中通过给定组所捕获序列的开始索引。 public int end(): 返回最后匹配字符后的偏移量。 public int end(int group): 返回之前匹配操作中通过给定组所捕获序列的最后字符之后的偏移量。 研究方法 研究方法(study methods)回顾输入的字符串,并且返回一个用于指示是否找到模式的布尔值。 public boolean lookingAt(): 尝试从区域开头处开始,输入序列与该模式匹配。 public boolean find(): 尝试地寻找输入序列中,匹配模式的下一个子序列。 public boolean find(int start): 重置匹配器,然后从指定的索引处开始,尝试地寻找输入序列中,匹配模式的下一个子序列。 public boolean matches(): 尝试将整个区域与模式进行匹配 替换方法 替换方法(replacement methods)用于在输入的字符串中替换文本有用处的方法。 public Matcher appendReplacement(StringBuffer sb, String replacement):实现非结尾处的增加和替换操作。 public StringBuffer appendTail(StringBuffer sb):实现结尾处的增加和替换操作。 public String replaceAll(String replacement):使用给定的替换字符串来替换输入序列中匹配模式的每一个子序列。 public String replaceFirst(String replacement):使用给定的替换字符串来替换输入序列中匹配模式的第一个子序列。 public static String quoteReplacement(String s):返回指定字符串的字面值来替换字符串。这个方法会生成一个字符串,用作 Matcher 的 appendReplacement 方法中的字面值替换 s。所产生的字符串将与作为字面值序列的 s 中的字符序列匹配。斜线(\)和美元符号($)将不再有特殊意义了。

getScheme()方法返回请求的计划,比如http,https或者ftp.
getServerName()方法返回被发送请求的服务器的主机名
getServerPort()方法返回被发送请求的端口号。
getContextPath()返回请求地址的根目录,以"/"开关,但不是以"/"结尾。
一个常用的获得服务器地址的连接字符串是:
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
