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","
");  
  %>  

方法二：

replace("/r/n"   ,"
");
