<package name="default" extends="struts-default">
<action name="showPerson" class="com.luob.action.ShowPerson">
<result name="success">/showPerson.jsp</result>
</action>
</package>
</struts>
3.Action
package com.luob.action;
import com.luob.model.Person;
import com.opensymphony.xwork2.ActionSupport;
public class ShowPerson extends ActionSupport {
private Person person; //采用POJO的方式进行赋值和存值
@Override
public String execute() throws Exception {
// TODO Auto-generated method stub
return SUCCESS;
}
public Person getPerson() {
return person;
}
public void setPerson(Person person) {
this.person = person;
}
}
4.POJO 对象
package com.luob.model;
public class Person {
private String name;
private String sex;
private String age;
private String address;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
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;
}
}
6.赋值jsp页面
<body>
<center>
<s:form action="showPerson" method="post">
<s:textfield name="person.name" label="姓名"/>
<s:textfield name="person.sex" label="性别"/>
<s:textfield name="person.age" label="年龄"/>
<s:textfield name="person.address" label="住址"/>
<s:submit value="提交"/>
</s:form>
</center>
</body>
7.取值jsp页面
<body>
<center>
<h3>使用POJO</h3><br/>
<hr>
姓名：${person.name}
性别：${person.sex}
年龄：${person.age}
地址：${person.address}
