页面常用传值关系

//获取页面传过来的id

String result = request.getParameter("result");

 

//将值传给页面（jstl传值方式）

1.   protected HttpServletRequest request;// request对象

      public void setServletRequest(HttpServletRequest request) {
           // TODO Auto-generated method stub
              this.request = request;
           }

            request.setAttribute("bigLogoName",bigLogonName);

2.   //struts标准传值

       private String auditUser;
       public String getAuditUser() {
            return auditUser;
        }

        public String list() {

        try {
                operateAudit = new OperateAuditDO();
                operateAudit.setOperate_user(userId);
                operateAuditService.getOperateList(operateAudit, this.paginationList);
                 auditUser = userId;
                return SUCCESS;

              }

 // 页面获得可以直接使用list.jsp

        <s:property value='auditUser'/>

       <s:if test="auditUser==operate_user">

 

 

//将值放入session以便操作

HttpSession session = request.getSession();

session.setAttribute("reportViewObject", reportViewObject);
 session.setAttribute("queryp", paramsMap);

 

//打印值

response.getWriter().print("{success:true,msg:'成功'}");

 

//方法名称: setResultMessages|描述:设置session中存储的处理信息结果
    public void setResultMessages(String resultMessages) {
        log.info(request.getHeader("user-agent"));
        log.info(request.getHeader(request.getLocale().toString()));
        if (!"zh_CN".equalsIgnoreCase(request.getLocale().toString())) {
            resultMessages = chr2Unicode(resultMessages);
        }
        log.info(resultMessages);
        request.getSession().setAttribute(RESULT_MESSAGE, resultMessages);
    }

 

// 中文转unicode字符(英文环境)
    public String chr2Unicode(String str) {
        String result = "";
        if (StringUtils.isNotEmpty(str)) {
            for (int i = 0; i < str.length(); i++) {
                int chr = (char) str.charAt(i);
                result += "\\u" + Integer.toHexString(chr);
            }
        }
        return result;
    }

 

// 输出至页面
    public void out2page(String a) {
        //response.setContentType("text/html;charset=UTF-8");
        response.setContentType("text/html;charset=UTF-8");
        //response.setCharacterEncoding("UTF-8");
        response.setHeader("Cache-Control",
                "no-store, max-age=0, no-cache, must-revalidate");
        // Set IE extended HTTP/1.1 no-cache headers.
        response.addHeader("Cache-Control", "post-check=0, pre-check=0");
        response.setHeader("Pragma", "no-cache");
        PrintWriter out;
        try {
            out = response.getWriter();
            out.print(a);
            log.info(a);
            out.close();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
