简介：

1.表单的提交

表单和对应的Java模型的类

在此次的例子中，我们将会模仿一个用户提交表单的动作，具体提交表单做什么，不关心，我们需要知道 first last Name，Email address ，age。

为了封装这个数据，我们提供一个简单的java Class 来存储这个信息。

Person.java

package org.apache.struts.helloworld.model;public class Person{    private String firstName;    private String lastName;    private String email;    private int age;     public String getFirstName()    {        return firstName;    }     public void setFirstName(String firstName)    {        this.firstName = firstName;    }     public String getLastName()    {        return lastName;    }     public void setLastName(String lastName)    {        this.lastName = lastName;    }     public String getEmail()    {        return email;    }     public void setEmail(String email)    {        this.email = email;    }     public int getAge()    {        return age;    }     public void setAge( int age)    {        this.age = age;    }      public String toString()    {        return "First Name: " + getFirstName() + " Last Name:  " + getLastName() +         " Email:      " + getEmail() + " Age:      " + getAge() ;    }}

表单的展示：

      register.jsp

     <%@ taglib prefix="s" uri="/struts-tags" %><%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
     
Register for a prize by completing this form.
         
          
          
            
      
      
      

我们使用了标签，则需要添加taglib 命令

表单中定义了Action register，我们需要在structs.xml文件中生命。

<action name="register" class="org.apache.struts.register.action.Register" method="execute">

      <result name="success">/ThankYou.jsp</result>

    </action>

 

增加注册动作对应的Action

package org.apache.struts.register.action;import org.apache.struts.model.Person;import com.opensymphony.xwork2.ActionSupport;public class Register extends ActionSupport {    private static final long serialVersionUID = 1L;    private Person personBean;    @Override    public String execute() throws Exception {        // call Service class to store personBean's state in database        return SUCCESS;    }    public Person getPersonBean() {        return personBean;    }    public void setPersonBean(Person person) {        personBean = person;    }}

定义展示的ThankYou.jsp页面：

     <%@ taglib prefix="s" uri="/struts-tags" %><%@ page language="java" contentType="text/html; charset=ISO-8859-1"     pageEncoding="ISO-8859-1"%>
     
Thank you for registering for a prize.
   
Your registration information: 
       
   
Return to home page.
   

在index.jsp中添加：

<p><a href="register.jsp">Please register</a> for our prize drawing.</p>

能够定位到register.jsp页面。

测试：

1. index.action

2. 点击注册

3.提交
