拉面初学者笔记——Struct2中获取request

拉面菜鸟笔记——Struct2中获取request

?

1. ActionContext

在Struts2开发中,除了将请求参数自动设置到Action的字段中,我们往往也需要在Action里直接获取请求(Request)或会话(Session)的一些信息,甚至需要直接对JavaServlet Http的请求(HttpServletRequest),响应(HttpServletResponse)操作. 我们需要在Action中取得request请求参数"username"的值:

public class UserAction extends ActionSupport implements SessionAware, ServletRequestAware, ServletResponseAware {    private HttpServletRequest request;     private HttpServletResponse response;    public void setServletRequest(HttpServletRequest request) {         this.request = request;     }    public void setServletResponse(HttpServletResponse response) {         this.response = response;     }    public String execute() {         HttpSession session = request.getSession();         return SUCCESS;     } }
