怎么读出数据库里面的空格和回车?

我给你个例子片断看看吧<%@ page contentType="text/html; charset=GBK" %>
<%@ page import="com.action.*,com.obj.*,com.tools.*"%>
<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
  <meta name="GENERATOR" content="Microsoft FrontPage 4.0">
  <meta name="ProgId" content="FrontPage.Editor.Document">
   <title>人才招聘</title>
<link rel="stylesheet" href="images/style1.css" type="text/css">
  <SCRIPT LANGUAGE="JavaScript">

</head>
<body bgcolor="#eeeeee">
  <div align="center">
  <center>
   <table width="716" height="541" bgcolor="#FFFFFF">
  <jsp:useBean id="table" scope="page" class="com.action.ListJob"/>
  <%
    Job[] job=table.getJobs(pageContext) ;
    int total=0;//当前页面有多少条记录
    int currPage=table.getCurPage() ;//当前页码
    int pageCount=table.getPageCount() ;//总页数
    int rCount=table.getRowCount() ;//总行数
    if(job!=null)
      {
       total=job.length ;
      }
   %>
  <td height="496">
   <table>
   <tr>
     <td width="550"><font color="#cc6600" size="3"><b>人才招聘＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿＿</b>
     </font>
     </td>
   </tr>
   <tr>

   </tr>
   <tr>
     <td width="550"><b>本公司招聘以下人员</b>： <p>　
     </td>
    </tr>
  </table>
<%
   for(int i=0;i<total ;i++)
    {
      Job current=job[i];
  %>
<table border="0" width="73%" cellpadding="2" cellspacing="4">
   <tr>
<%//留言板换行处理
    String text=current.getNeeds() ;//从数据库中提出来的数据
    int index=text.indexOf("\r\n") ;
    while(index!=-1)
     {
       text=text.substring(0,index)+"<br>"+text.substring(index+2);
       index=text.indexOf("\r\n") ;
     }
  %>
      <td width="65%"><%=4*currPage-3+i%>
      </td>
    </tr>
       <td width="35%" align="center">招聘职位：

       <td width="65%"><%=current.getJob()%>
       </td>
     </tr>
     <tr>

  <%
    if(job!=null)
     {

  <form name="PageForm" action="rencai.jsp" onSubmit="return testform(this)">

     if(currPage>1)
       {

     <a href="rencai.jsp?page=1">首页</a>
     <%
       }
     %>
   <%
    if(currPage>1)
     {
   %>
     <a href="rencai.jsp?page=<%=currPage-1%>">上一页</a>
      <%
        }
      %>
   <%
     if(currPage<pageCount)
       {
    %>
      <a href="rencai.jsp?page=<%=currPage+1%>">下一页</a>
      <%
        }
      %>
    <%
      if(currPage<pageCount)
       {
     %>
       <a href="rencai.jsp?page=<%=pageCount%>">尾页</a>
       <%
         }
       %>        跳到
        <input type="text" name="page" size="4" style="font-size:9px" onBlur="this.value=onlynumber(this.value);" value=1>
             页
        <input type="submit" name="submit" size="4" value="GO" style="font-size:12px">

    </form>
    <%
    }
    %>
  <tr>
    <td height="37">
  <jsp:include page="copyright.jsp"/>
  </tr>
    </table>
    </center>
  </div>
</body>
</html>
给你一个转换的JavaBean:
package com.chenyue.html;
public class HtmlEncode{
  String re;
  //用指定的字符串替换字符串中某个字符的方法
  public String replace(String con,String tag,String rep){
    int j=0;
    int i=0;
    int k=0;
    String RETU="";
    String temp=con;
    int tagc=tag.length();
    while(i<con.length()){
      if(con.substring(i).startsWith(tag)){
        temp=con.substring(j,i)+rep;
        RETU+=temp;
        i+=tagc;
        j=i;
      }
      else
        i+=1;
    }
    RETU+=con.substring(j);
    return RETU;
  }
  //对字符串进行编码的方法
  public String HtmlEncode(String s){
    re=replace(s,"<","<");
    re=replace(re,">",">");
    re=replace(re,"\n","<br>");
    re=replace(re," "," ");
    //re=replace(re,"'","&#39");
    return re;
  }
}
你直接在页面加入
<pre>
XXX-->要显示的内容
</per>
你可以这样试试,昨天也有人问这样的问题，好象他已经这样给解决了，希望能给你帮助,^_^!
