java - jsp 未以正确格式传递 UTF-8 数据

我希望 JSP 页面支持 UTF8 数据，我能够使用 struts2 和 jsp 进行本地化，但是当我以本地语言在 jsp 上从用户那里获取数据时，信息不会以正确的格式运行，而是会传递一些抓取的数据。 这是我的jsp代码:-----

<%@ page language="java" contentType="text/plain; charset=UTF-8"
    pageEncoding="UTF-8"%>
      <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@page import="java.util.*"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/plain; charset=UTF-8">
<title><s:text name="global.addnewcustomer"/></title>
<script type="text/javascript" src="http://localhost:9090/AMCMSWeb/basic/validation/Login.js">
</script>
</head>
<body>
<h2 align="center"><s:text name="global.fillinfo"/></h2>
    <s:form action="addcustomeraction" method="post" acceptcharset="UTF-8">

<table align="center" border="1" bgcolor="pink" bordercolor="gray">
<tr>
    <td><s:text name="global.custName"/></td>
    <td>:</td>
    <td><s:textfield name="custName" size="15"></s:textfield></td>
    <td><s:text name="global.custMidleName"/></td><td>:</td><td><s:textfield name="custMidleName" size="15"></s:textfield></td>
    <td><s:text name="global.custLastName"/></td><td>:</td><td><s:textfield name="custLastName" size="15"></s:textfield></td>
</tr>
<tr>
    <td><s:text name="global.mobileNo"/></td><td>:</td><td><s:textfield name="mobileNo" size="15"></s:textfield></td>
    <td><s:text name="global.phoneNo"/></td><td>:</td><td><s:textfield name="phoneNo" size="15"></s:textfield></td>
    <td><s:text name="global.toDate"/>&nbsp;<s:label>(mmm/dd/yyyy)</s:label></td><td>:</td><td><s:textfield name="toDate" size="15" readonly="true">
                <s:param name="value">
                        <s:date name="new java.util.Date()" format="MM/dd/yyyy"/>
                </s:param>
    </s:textfield></td>
</tr>
<tr>
    <td><s:text name="global.atPost"/></td><td>:</td><td><s:textarea name="atPost" cols="15" rows="3"></s:textarea></td>
</tr>
<tr>
    <td><s:text name="global.taluka"/></td><td>:</td><td><s:select list="#{'Miraj':'Miraj','Haveli':'Haveli'}" name="taluka" headerKey="-1" headerValue="Select Taluka" ></s:select></td>
    <td><s:text name="global.district"/></td><td>:</td><td><s:select list="#{'Sangli':'Sangli','Pune':'Pune'}" name="district" headerKey="-1" headerValue="Select District"></s:select></td>
</tr>
<tr>
    <td><s:text name="global.state"/></td>
    <td>:</td>
    <td><s:select list="#{'Maharashtra':'Maharashtra','Karnataka':'Karnataka'}" name="state" headerKey="-1" headerValue="Select State" onchange="list_districts()"></s:select></td>
    <td><s:text name="global.country"/></td><td>:</td><td><s:select  list="#{'India':'India'}" name="country" headerKey="-1" headerValue="Select Country" ></s:select></td>
</tr>
<tr>
    <td><s:text name="global.pinCode"/></td>
    <td>:</td>
    <td><s:textfield name="pinCode"  type="" size="15"></s:textfield></td>
</tr>
</table>

<table align="center" >
     <tr>
        <td><s:submit name="s" key="global.proceed"/></td>  
        <td><input type="button" name="cancel" value="  X  "></td>
     </tr>
</table>
    </s:form>

最佳答案

页面(或 web.xml)中指定的字符编码应用于 HTTP 通信的以下阶段:

  1. 准备/将请求从客户端发送到服务器
  2. 在服务器中接收/读取请求
  3. 准备/将响应从服务器发送到客户端
  4. 接收/读取客户端中的响应

应用程序服务器是第 2 阶段的唯一负责人。

您需要查找特定的应用程序服务器设置，以更改默认字符编码(很容易是 ISO-8859-1 )，并将其更改为在 UTF-8 中工作。 .

例如，在 Tomcat 中，您需要编辑 conf/server.xml文件，通过添加 URIEncoding="UTF-8"参数 <Connector> ，例如来自

<Connector port="8090" />

到

<Connector port="8090" URIEncoding="UTF-8"/>

In the Apache Wiki there is a nice list of things to check确保所有组件都以 UTF-8 运行:

What can you recommend to just make everything work? (How to use UTF-8 everywhere).

Using UTF-8 as your character encoding for everything is a safe bet. This should work for pretty much every situation.

In order to completely switch to using UTF-8, you need to make the following changes:

  1. Set URIEncoding="UTF-8" on your in server.xml. References: HTTP Connector, AJP Connector.
  2. Use a character encoding filter with the default encoding set to UTF-8
  3. Change all your JSPs to include charset name in their contentType. For example, use <%@page contentType="text/html; charset=UTF-8" %> for the usual JSP pages and <jsp:directive.page
    contentType="text/html; charset=UTF-8" />     for the pages in XML syntax (aka JSP Documents).
  4. Change all your servlets to set the content type for responses and to include charset name in the content type to be UTF-8. Use response.setContentType("text/html; charset=UTF-8") or response.setCharacterEncoding("UTF-8").
  5. Change any content-generation libraries you use (Velocity, Freemarker, etc.) to use UTF-8 and to specify UTF-8 in the content type of the responses that they generate.
  6. Disable any valves or filters that may read request parameters before your character encoding filter or jsp page has a chance to set the encoding to UTF-8. For more information see http://www.mail-archive.com/users@tomcat.apache.org/msg21117.html.
