目的：按用户的“本来面目”显示录入的数据 －－有回车的话显示处理就得换行。。。。
操作数据库代码里：
String text = text1.replaceAll("\n","<br>").trim();
boardItem.setText(text);
在detail页面上：<bean:write name = "BoardItemForm" property="text" filter="flase"/>
～～～～～关键
但是在edit页面遇到了问题：
这样行不通：(回车的地方都显示成了<br>)
<html:textarea property="text" cols="50" rows="10" value="<bean:write name = "BoardItemForm" property="text" filter="flase"/>">
</html:textarea>
找了不少资料，其中有一个人提到：
In Ted's answer above, it is given: value="<bean:write name="employeeBean" property="name"/>" value should be enclosed in single quotes and not double quotes. value='<bean:write name="employeeBean" property="name"/>' It will work. Courtesy: Ted's own Struts book.

Failed too!
So i chose define tag,but it doesn't have filter value
For about half of hour's thinking,at last I chose:
<!--replace <br> with \n-->
<bean:define id="text" name="BoardItemForm" property="text" type="String"/>
<%
String realText = text.replaceAll("<br>","\n");
%>
<bean:message key="common.text"/>:
<html:textarea property="text" cols="50" rows="10" value="<%=realText%>">
</html:textarea>
ok,done although not so perfect!
It's time to go to bed!
Good night!
