一、使用 Aware拦截器
这种方法需要Action类实现相应的拦截器接口。代码如下
...
import org.apache.struts2.interceptor.RequestAware;
import org.apache.struts2.interceptor.ServletResponseAware;
...
public class AdminAction implements Action, RequestAware, ServletResponseAware{
private Map request;
private HttpServletResponse response;
@Override
public void setRequest(Map<String, Object> request) {
this.request = request;
}
@Override
public void setServletResponse(HttpServletResponse response) {
this.response = response;
}
...
}
二、 使用ActionContext类，比较简单。代码如下
...
import com.opensymphony.xwork2.ActionContext;
...
public class MyAction implements Action {
private ActionContext atx = ActionContext.getContext();
private HttpServletRequest request = (HttpServletRequest) atx.get(ServletActionContext.HTTP_REQUEST);
private HttpServletResponse response = (HttpServletResponse) atx.get(ServletActionContext.HTTP_RESPONSE);
...
}
三、使用servletactioncontext类，最简单的方式。代码如下
import org.apache.struts2.ServletActionContext;
...
public class MyAction implements Action {
private HttpServletRequest request = ServletActionContext.getRequest();
private HttpServletResponse response = ServletActionContext.getResponse();
...
}
最简单的就是最后一个，根据需求自己选择吧~~
