本文介绍了解决中文乱码问题的解决方案，通过在index.jsp、saveinfo.jsp及bookinfo.jsp文件中添加特定代码段，确保了中文字符正确显示。详细步骤包括设置页面编码为gb2312，并在请求中设置字符集为gb2312，适用于需要处理中文数据的应用场景。

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>

bookinfo.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>书籍信息</title>
</head>
<body>
<% request.setCharacterEncoding( "gb2312");%>
<jsp:useBean id="bookbean" scope="session" class="com.javaBean.viewbook"></jsp:useBean>
<jsp:setProperty name="bookbean" property="*"/>
<table border="1">

</table>
</body>
</html>

viewbook.java文件

package com.javaBean;

/**
* Session Bean implementation class viewbook
*/

public class viewbook {
int bid;
String bname;
int bnumber;
String bauthor;

    /**
     * Default constructor.
     */
    public viewbook() {
        // TODO Auto-generated constructor stub
    }

    public void setBid(int bid) {
  this.bid=bid;
}
    public int getBid() {
  return bid;
}

    public void setBname(String bname) {
  this.bname=bname;
}
    public String getBname() {
  return bname;
}

    public void setBnumber(int bnumber) {
  this.bnumber=bnumber;
}
    public int getBnumber() {
  return bnumber;
}

    public void setBauthor(String bauthor) {
  this.bauthor=bauthor;
}
    public String getBauthor() {
  return bauthor;
}
