本文介绍如何在Struts框架中使用实体对象进行表单数据的映射及处理流程，包括实体对象定义、ActionForm封装实体、页面表单元素与实体属性的对应关系以及配置文件设置。

1. 新建实体对象Student

public class Student {
private String userName;
private int age;
private String address;
public String getUserName() {
  return userName;
}
public void setUserName(String userName) {
  this.userName = userName;
}
public int getAge() {
  return age;
}
public void setAge(int age) {
  this.age = age;
}
public String getAddress() {
  return address;
}
public void setAddress(String address) {
  this.address = address;
}
@Override
public String toString() {
  // TODO Auto-generated method stub
  return userName+age+address;
}
}

2. 新建ActionForm,将实体对象作为其成员变量

public class RegistForm extends ActionForm {
private int count;
private Student student = new Student();
public Student getStudent() {
return student;
}
public void setStudent(Student student) {
this.student = student;
}
}

3. 创建页面,页面中input元素的name属性为实体对象名.属性名

<form action="regist2.do" method="get">
name:<input type="text" name="student.userName">
age :<input type="text" name="student.age">
address:<input type="text" name="student.address">
<input type="submit" name="button1">
</form>

4. 配置struts-config.xml

5. 创建Action,当该execute方法被调用时，ActionForm当中的实体对象已经被填充值

  public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response) {
  //页面对象
  RegistForm rf = (RegistForm)form;
  //封装业务对象BO
  Student s = rf.getStudent();
  System.out.println(s);
  StudentBiz sBiz = new StudentBiz();
  sBiz.save(s);
  return mapping.findForward("success");
}
