[JSP] 利用JavaBean来传递表单数据
利用JavaBean来传递表单数据
新建一个表单, 用来提交数据, 代码如下
<form name="login" action="loginResponse.jsp">
请输入您的用户名:<br />
<input type="text" name="user_name"/><br />
请输入您的年龄:<br />
<input type="text" name="user_age"/><br />
请输入您的地址:<br />
<input type="text" name="user_address"/><br />
<input type="submit" value="OK"/>
<input type="reset" value="Reset"/>
</form>
新建一个 Java class, 命名为: loginBean, 代码如下:
package javabean;
publicclass loginBean {
private String name;
privateint age;
private String address;
public String getAddress() {
return address;
}
publicvoid setAddress(String address) {
this.address = address;
}
publicint getAge() {
return age;
}
publicvoid setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
publicvoid setName(String name) {
this.name = name;
}
}
新建一个jsp网页, 命名为: loginResponse, 将会在此页面上应用JavaBean, 代码如下:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<jsp:useBean id="loginBean" class="javabean.loginBean"/>
<jsp:setProperty property="name" name="loginBean" param="user_name"/>
<jsp:setProperty property="age" name="loginBean" param="user_age"/>
<jsp:setProperty property="address" name="loginBean" param="user_address"/>
Your name is: <jsp:getProperty property="name" name="loginBean"/><br />
Your age is: <jsp:getProperty property="age" name="loginBean"/><br />
Your address is: <jsp:getProperty property="address" name="loginBean"/><br />
</body>
</html>
