jsp页面里面回车问题

通过JSP将回车符转化成HTML标签

方法一：

public String replace(String parentStr,String ch,String rep) {
int i = parentStr.indexOf(ch);
StringBuffer sb = new StringBuffer();
if (i == -1)
return parentStr;
sb.append(parentStr.substring(0,i) + rep);
if (i+ch.length() < parentStr.length())
sb.append(replace(parentStr.substring(i+ch.length(),parentStr.length()),ch,rep));
return sb.toString();
}
%>
<%//调用
str=replace(str," "," ");
str=replace(str,"/n","<br/>");
%>

方法二：

replace("/r/n" ,"<br>");
