Struts2接受参数。

Struts2接受参数方式可以分为三种。

第一种：

用action里的属性；

在action定义要接受的参数的；并提供 set get方法；

跟表单里的参数也一样，不用作强制类型转换；

public class canshuaction {

private String name;

private int age;

//省略setter,getter方法；

public String execute(){

System.out.println("name="+name);

}

第二种：

Domain model;

example；

package com.test.action;

import com.opensymphony.xwork2.ActionSupport;

public class DomainModelAction extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
public User user;
public User getUser() {
  return user;
}
public void setUser(User user) {
  this.user = user;
}
public String execute(){
  System.out.println("username:"+user.getUserName()+";passwd:"+getUser().getPasswd());
  return SUCCESS;
}

}

第三种:

ModelDriven

public class ModelDrivenAction extends ActionSupport implements ModelDriven<User> {
    private User user = new User();
    public String execute(){
    System.out.println("userame:"+user.getUserName()+";password:"+user.getPasswd());
    return SUCCESS;
    }
public User getModel() {
  // TODO Auto-generated method stub
  return this.user;
}

}

index.jsp

<body>
    <h3>say hello to:</h3>
    <s:form action="modeldriven" method="post">
      name:<s:textfield name="username"></s:textfield>
      passwd:<s:password name="passwd"></s:password>
