action类:
[java]view plaincopyprint?
package action;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
publicclass MessageAction extends ActionSupport{;
private String userName; //变量名要和表单的名字一样，这样才能自动接收表单数据
privatestaticfinallong serialVersionUID = 1L;
//方法get和set不能少,不然会取不到表单数据。
public String getUserName() {
return userName;
}
publicvoid setUserName(String userName) {
this.userName = userName;
}
public String execute(){
System.out.println("execute");
System.out.println(userName);
ServletActionContext.getRequest().setAttribute("info",userName);
return SUCCESS;
}
}

struts.xml配置如下：
<struts>
<package name="default" namespace="/" extends="struts-default">
