struts2使用实例代码,通过这些实例

package com.briup.tag;
import javax.servlet.ServletContext;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.apache.struts2.ServletActionContext;
import com.briup.pojo.Book;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.util.ValueStack;
public class OgnlAction {
	private String company;
	
	public String getCompany() {
		return company;
	}

	public void setCompany(String company) {
		this.company = company;
	}

	public String execute()throws Exception{
		ActionContext ac
			=ActionContext.getContext();
		ValueStack vs=ac.getValueStack();
		Book book=new Book(1L,"struts",30.0);
		//将book对象放入值栈
		vs.push(book);
		//将age放入值栈维护的map中
		vs.set("age",28);
		ac.getContextMap().put(
				"abc", "briup");
		HttpServletRequest req
		=ServletActionContext.getRequest();
		HttpSession session=req.getSession();
		ServletContext sc
		=ServletActionContext.getServletContext();
		req.setAttribute(
		"scope", "requestScope");
		session.setAttribute(
		"scope", "sessionScope");
		sc.setAttribute(

		company="briup";
		return "success";
