struts2 textfield的标记(struts2 tag for textfield)

 开发演示应用程序。 
 
 错误：无法解析push标签下的属性。 姓名和年龄 
 
 形成： 
 
<s:form action="addStudentAction" method="POST">
    <s:push value="student">
        <s:textfield name="name" label="Name : " value="" />
        <s:textfield name="age" label="Age : " value=""/>
    </s:push>
    <s:submit/>
</s:form>
 
 动作与模特： 
 
public class StudentAction extends ActionSupport implements ModelDriven {

    Student student = new Student();


    @Autowired
    StudentService studentService;

    public Object getModel() {
        return student;
    }

    public String execute(){
        return SUCCESS;
    }


    public String addStudent() throws Exception {
        student.setCreatedDate(new Date());
        studentService.add(student);
        return SUCCESS;
    }


    public Student getStudent() {
        return student;
    }

    public void setStudent(Student student) {
        this.student = student;
    }


}

package com.myapp.model;

import java.util.Date;

public class Student {

    private Long id;
    private String name;
    private Integer age;
    private Date createdDate;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

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

    public Date getCreatedDate() {
        return createdDate;
    }

    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }


}
 
 EDITED 
 
public class StudentAction extends ActionSupport implements ModelDriven<Student> {

    Student student = new Student();
    List<Student> studentList = new ArrayList<Student>();

    @Autowired
    StudentService studentService;

    public Student getModel() {
        return student;
    }

    public String execute(){
        return SUCCESS;
    }


    public String addStudent() throws Exception {
        student.setCreatedDate(new Date());
        studentService.add(student);
        return SUCCESS;
    }

}
 
 仍然没有解决属性。 查看选项。 model.name将解析该属性。 
 
 
**struts.xml**

        <constant name="struts.devMode" value="true"/>

        <package name="default" namespace="/" extends="struts-default">

Developing a demo application.
 
Error: Can not resolve properties under push tag. name and age
 
FORM:
 
<s:form action="addStudentAction" method="POST">
    <s:push value="student">
        <s:textfield name="name" label="Name : " value="" />
        <s:textfield name="age" label="Age : " value=""/>

Action & model:
 
public class StudentAction extends ActionSupport implements ModelDriven {

    Student student = new Student();


    @Autowired
    StudentService studentService;

    public Object getModel() {
        return student;
    }

    public String execute(){
        return SUCCESS;
    }


    public String addStudent() throws Exception {
        student.setCreatedDate(new Date());
        studentService.add(student);
        return SUCCESS;
    }


    public Student getStudent() {
        return student;
    }

    public void setStudent(Student student) {
        this.student = student;
    }


}

package com.myapp.model;

import java.util.Date;

public class Student {

    private Long id;
    private String name;
    private Integer age;
    private Date createdDate;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

    public Integer getAge() {
        return age;
    }

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

    public Date getCreatedDate() {
        return createdDate;
    }

    public void setCreatedDate(Date createdDate) {
        this.createdDate = createdDate;
    }


}
 
EDITED
 
public class StudentAction extends ActionSupport implements ModelDriven<Student> {

    Student student = new Student();
    List<Student> studentList = new ArrayList<Student>();

    @Autowired
    StudentService studentService;

    public Student getModel() {
        return student;
    }

    public String execute(){
        return SUCCESS;

    public String addStudent() throws Exception {
        student.setCreatedDate(new Date());
        studentService.add(student);
        return SUCCESS;
    }

}
 
Still properties are not resolved. See the options. model.name will resolve the property.
