在struts2的<s:form>里面配置一个theme="simple"。就可以解决struts2标签自动换行的问题。
例子：
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>LXIT通讯录</title>
<style type="text/css">
