一．非Ioc方式

这种方式主要是利用了com.opensymphony.xwork2.ActionContext类以及org.apache.struts2.ServletActionContext类，具体的方法如下所示。

获得request对象：

1)．HttpServletRequest request = ServletActionContext.getRequest ();

2)．ActionContext ct= ActionContext.getContext();

       HttpServletRequest request=(HttpServletRequest)ct.get(ServletActionContext.HTTP_REQUEST);

获得response对象：

1)．HttpServletResponse response= ServletActionContext.getResponse ();

2)．ActionContext ct= ActionContext.getContext();

       HttpServletResponse response=(HttpServletResponse )ct.get(ServletActionContext.HTTP_RESPONSE);

 

二：IOC方式

Action在继承ActionSupport的同时还要实现ServletRequestAware和ServletResponseAware接口

 

               package com.iterator.action;                    import javax.servlet.http.HttpServletRequest;          import javax.servlet.http.HttpServletResponse;                    import org.apache.struts2.interceptor.ServletRequestAware;          import org.apache.struts2.interceptor.ServletResponseAware;                    import com.opensymphony.xwork2.ActionSupport;                    public class Struts2GetServletRequestAction extends ActionSupport implements                  ServletRequestAware, ServletResponseAware {                        private static final long serialVersionUID = 1L;              private HttpServletRequest request;              private HttpServletResponse response;                            public void setServletRequest(HttpServletRequest request) {                  this.request=request;              }                        public void setServletResponse(HttpServletResponse response) {                  this.response=response;              }                        @Override              public String execute() throws Exception {                  System.out.println("requestUsername=" + request.getParameter("username") + ",requestPassword=" + request.getParameter("password"));                  return SUCCESS;              }          }
package com.iterator.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

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

import com.opensymphony.xwork2.ActionSupport;

public class Struts2GetServletRequestAction extends ActionSupport implements
        ServletRequestAware, ServletResponseAware {

    private static final long serialVersionUID = 1L;
    private HttpServletRequest request;
    private HttpServletResponse response;

    public void setServletRequest(HttpServletRequest request) {
        this.request=request;
    }

    public void setServletResponse(HttpServletResponse response) {
        this.response=response;
    }

    @Override
    public String execute() throws Exception {
        System.out.println("requestUsername=" + request.getParameter("username") + ",requestPassword=" + request.getParameter("password"));
        return SUCCESS;
    }
}
