calaction.java

关于Struts2的一些编程例子集合！希望对学习Struts2的朋友有帮助！

package com.briup;
import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;
import org.apache.struts2.interceptor.ServletRequestAware;

public class CalAction implements ServletRequestAware {
	private int n1;
	private int n2;
	private int result;
	private HttpServletRequest request;
	public String execute(){
		result=n1+n2;
		request.setAttribute("r", result);
		/*
		 * 方法链
		 * getSession()
		 * getSession(true):和getSession()一样
		 * getSession(false):如果没session不会创建session
		 */
		ServletActionContext.getRequest().getSession().setAttribute("rs", result);
		return "success";
	}
	public int getN1() {
		return n1;
	}
	public void setN1(int n1) {
		this.n1 = n1;
	}
	public int getN2() {
		return n2;
	}
	public void setN2(int n2) {
		this.n2 = n2;
	}
	public int getResult() {
		return result;
	}
	public void setResult(int result) {
		this.result = result;
	}
	//拦截器调用，比execute()先调用
	public void setServletRequest(HttpServletRequest arg0) {
		request=arg0;
	}
	
}
