目的：
1.创建一个表单在index.jsp页面中，如图：
代码如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>我自己的主页</title>
</head>
<body>
<form action="deal.jsp" method="post" name="student">
姓名：<input type="text" name="name"><br>
年龄：<input type="text" name="age"><br>
地址：<input type="text" name="address"><br>
<input type="submit" name="submit" value="确认">
</form>
</body>
</html>
2.输入姓名、年龄、地址，在deal.jsp页面中通过表格表现出来，如图：
代码如下：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>
<jsp:useBean id="student" class="hello.Student"></jsp:useBean>
<jsp:useBean id="charset" class="hello.CharSet"></jsp:useBean>
<jsp:setProperty property="*" name="student"/>
<table width="200" height="50" border="1" align="center">
<tr> <td width=50%>姓名：</td> <td><%=charset.toString(student.getName())%></td></tr>
<tr> <td width=50%>年龄：</td> <td><%=charset.toString(student.getAge())%></td></tr>
<tr> <td width=50%>地址：</td> <td><%=charset.toString(student.getAddress())%></td> </tr>
</table>
</body>
</html>
3.建立Studentl类，遵循JavaBean规则，代码如下：
package hello;
public class Student {
private String name;
private String age;
private String address;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public Student() {
super();
}
}
4.建立字符处理类CharSet用来解决中文乱码，同样必须遵循JavaBean规则，代码如下：
package hello;
import java.io.UnsupportedEncodingException;
public class CharSet {
public CharSet() {
}
public String toString(String str){
String message="";
if(str!=null && !"".equals(str)){
try {
message = new String(str.getBytes("ISO-8859-1"),"UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
return message;
}
}
5.将项目加入Tomcat服务器并启动，成功解决了中文乱码；
