JSP传递参数中文乱码问题的一种解决方法-优快云博客

本文介绍了一种解决中文乱码的有效方法，通过设置request的字符编码为gb2312来确保表单提交的数据能够正确解析。示例使用了JSP页面及JavaBean进行展示。

最近经常会遇到中文乱码的问题，在解决问题的过程中，我又得知了一种蛮好的解决方法：

<% request.setCharacterEncoding(“gb2312”）;%>;

例如：

index.jsp文件

<%@ page language="java" contentType="text/html; charset=gb2312"
pageEncoding="gb2312"%>
<!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/html; charset=gb2312">
<title>输入书的相关信息</title>
</head>
<body>
<form action="saveinfo.jsp" method="post" name="bookinfo">

</table>

</form>
</body>
</html>

saveinfo.jsp文件

<%@ page language="java" contentType="text/html; charset=gb2312"
pageEncoding="gb2312"%>
<% request.setCharacterEncoding( "gb2312");%>
<!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/html; charset=gb2312">
<title>查看书籍信息</title>
</head>
<body>
<jsp:useBean id="bookbean" scope="session" class="com.javaBean.viewbook"></jsp:useBean>
<jsp:setProperty name="bookbean" property="*"/>
<a href="bookinfo.jsp">查看书籍信息</a>
</body>
</html>
