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
<?xml version="1.0" encoding="ISO-8859-1" ?> <%@ taglib prefix="s" uri="/struts-tags" %> <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Register</title>
</head>
<body>
<h3>Register for a prize by completing this form.</h3>
<s:form action="register">
<s:textfield name="personBean.firstName" label="First name" />
<s:textfield name="personBean.lastName" label="Last name" />
<s:textfield name="personBean.email" label ="Email"/>
<s:textfield name="personBean.age" label="Age" />
<s:submit/>
</s:form>
</body>
</html>
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：
<?xml version="1.0" encoding="ISO-8859-1" ?>
<%@ taglib prefix="s" uri="/struts-tags" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Registration Successful</title>
</head>
<body>
<h3>Thank you for registering for a prize.</h3> <p>Your registration information: <s:property value="personBean" /> </p> <p><a href="<s:url action='index' />" >Return to home page</a>.</p> </body>
</html>
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
