Struts2获取Request的常用2种方式，Session和Application类似

方法一：使用ServletActionContext

public class GetRequestAction extends ActionSupport{

    @Override

    public String execute() throws Exception {

        HttpServletRequest request = ServletActionContext.getRequest();

        return SUCCESS;

    }

}

方法二：通过实现ServletRequestAware接口

public class GetRequestAction extends ActionSupport implements ServletRequestAware{

    private HttpServletRequest request;

    

    public void setServletRequest(HttpServletRequest request) {

        this.request = request;

    }

    

}
