Three methods for passing parameters in Struts2

1.

package com.xjtu.st;import com.opensymphony.xwork2.ActionSupport;import com.xjtu.dto.DTOStudent;import com.xjtu.vo.Student;public class T extends ActionSupport {String name;public String exe() {System.out.println(name);return "success";}public String getName() {return name;}public void setName(String name) {this.name = name;}}

On the website, write :.....? Name = aaa

Output name aaa in the background

2.

Public class T extends ActionSupport {Student s; // Student class public String exe () {System. out. println (s. getName ());
                System.out.println(s.getAge());
Return "success";} public Student getStudent () {return s;} public void setStudent (Student s) {this. s = s ;}}
On the website, write :.....? S. name = aaa & s. age = 3
In the background, the name aaa age is 3.
3.
package com.xjtu.st;import com.opensymphony.xwork2.ModelDriven;import com.xjtu.vo.Student;public class ModelDrivenDemo implements ModelDriven
  
   {Student a = new Student();public String exe(){System.out.println(a.getName());System.out.println(a.getAge());return "aaa";}public Student getModel() {// TODO Auto-generated method stubreturn a;}}
  
On the website, write :.....? Name = aaa & age = 3
In the background, the name aaa age is 3.
