struts2采用域模型方式接收参数

struts.xml:<struts><constant name="struts.i18n.encoding" value="gbk" /> <constant name="struts.devMode" value="true" />  <package name="user" namespace="/user" extends="struts-default">        <action name="user" method="post">

     <input type="submit" value="提交"/> </form>--------------------------Action:public class TestAction extends ActionSupport { private User user; public User getUser() {  return user; } public void setUser(User user) {  this.user = user; } public String rec() {  if(user != null) {   System.out.println("username=" + user.getUsername());   System.out.println("password=" + user.getPassword());  } else {   System.out.println(user);  }  return SUCCESS; }-----------------------------------
