jsp用户注册简单实例2

要求

编程实现用户注册，信息包括姓名、密码、年龄。提交后注册页面显示信息，分别通过request、bean属性、getProperty动作获取。

使用bean属性获取时需要建立java类如下：

UserRegisterBean类：

package bean;

public class UserRegisterBean {
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    private String name;
    private int pass;
    private int age;

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getPass() {
        return pass;
    }

    public void setPass(int pass) {
        this.pass = pass;
    }


}

使用request获取：<br>
姓名：<%=name%><br>
密码：<%=pass%><br>
年龄：<%=age%><br>
<hr>
使用bean属性获取：<br>
<%--<jsp:getProperty name="user" property="name"/>--%>
<jsp:useBean id="user" scope="page" class="bean.UserRegisterBean" >
    <jsp:setProperty name="user" property="*"/>

</jsp:useBean>
姓名：<%=user.getName()%><br>
<hr>
使用getProperty动作：<br>
密码：<jsp:getProperty name="user" property="pass"/><br>
年龄：<jsp:getProperty name="user" property="age"/>
</body>
