方法一：使用import org.apache.struts2.interceptor包下的ServletResponseAware和ServletRequestAware方法，需要Action类实现该方法！
public class TestAction implements ServletRequestAware,ServletResponseAware { private HttpServletRequest request; private HttpServletResponse response; @Override public void setServletResponse(HttpServletResponse response) { this.response=response; } @Override public void setServletRequest(HttpServletRequest request) { this.request=request; } }方法二：使用org.apache.struts2.ActionContext类的get方法得到request和response还有session对象
import java.util.Map; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.opensymphony.xwork2.ActionContext; public class TestAction { public String getObject() { HttpServletRequest request = (HttpServletRequest) ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_REQUEST); HttpServletResponse response = (HttpServletResponse) ActionContext.getContext().get(org.apache.struts2.StrutsStatics.HTTP_RESPONSE); Map<String, Object> session = ActionContext.getContext().getSession(); return null; } }方法三：Struts2为我们提供了最简单的方式，使用org.apache.struts2.ServletActionContext类，可以直接得到request，response和session方法
public class TestAction { public String getObject() { HttpServletRequest request = ServletActionContext.getRequest(); HttpServletResponse response = ServletActionContext.getResponse(); HttpSession session = ServletActionContext.getRequest().getSession(); return null; } }以上几种是常用的方法，还有一种方法是实现org.apache.struts2.interceptor.RequestAware接口，这种方法比较麻烦，使用得比较少，大家感兴趣的可以研究一下。
