jsp中的session在java檔案中取到
阿新 • • 發佈：2019-02-06
jsp頁面呼叫.mxml頁面,然後.mxml頁面呼叫後臺java檔案,在後臺java檔案中通過session 可以取道jsp頁面中的session的值.
<%@ page language="java" import="java.util.*,com.xbzc.phr.service.login.*" pageEncoding="utf-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'index.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <% String sid = request.getParameter("systemId"); //市級平臺上註冊的系統ID String pwd = request.getParameter("password"); //市級平臺上註冊的系統密碼 String did = request.getParameter("doctorUserId"); //醫生ID String dname = new String(request.getParameter("doctorUserName").getBytes("ISO-8859-1")); //醫生姓名 String unid = request.getParameter("uniqueId"); //患者註冊的唯一內部標識 String idtype = request.getParameter("idTypeCode"); //患者註冊的唯一內部標識型別 String vipo = request.getParameter("userRole"); // 檢視角色viewPole String vitar = request.getParameter("purposeOfRuse"); //檢視目的viewTarget String patiName = request.getParameter("patientName"); String patiSex = request.getParameter("patientSex"); String patiBirthDate = request.getParameter("patientBirthDate"); session.setAttribute("doctorUserId",did); // 醫生ID session.setAttribute("doctorUserName",dname); // 醫生姓名 session.setAttribute("uniqueId",unid); // 患者註冊的唯一內部標識 session.setAttribute("idTypeCode",idtype); // 患者註冊的唯一內部標識 session.setAttribute("systemId",sid); // 市級平臺上註冊的系統ID session.setAttribute("password",pwd); // 市級平臺上註冊的系統密碼 session.setAttribute("viewPole",vipo); // 檢視角色 session.setAttribute("viewTarget",vitar); //檢視目的 session.setAttribute("patientName",patiName); session.setAttribute("patientSex",patiSex); session.setAttribute("patientBirthDate",patiBirthDate); %> <jsp:forward page="PHBEMR.html"/> </body> </html>
上面的PHBEMR.html 其實是 PHBEMR.mxml,在 PHBEMR.mxml中呼叫了後臺的java,
public RPCMessage getURLParameter() { log.info("服務層操作：返回第三方傳過來的引數，第三方設定的引數在index.jsp中 getURLParameter()"); // log.info("驗證[" + userId + "]共享資訊"); HttpServletRequest request = FlexContext.getHttpRequest(); HttpSession session = request.getSession(); List<TURLParameterDTO> urlParameterList = new ArrayList<TURLParameterDTO>(); // Map<String,TURLParameterDTO> map = new // HashMap<String,TURLParameterDTO>(); TURLParameterDTO o = null; String idNumber = ""; String idTypeCode = ""; String uniqueId = (String) SessionUtils.getAttribute("uniqueId"); try { Enumeration<String> enumeration = (Enumeration<String>) session .getAttributeNames(); String attributeName; while (enumeration.hasMoreElements()) { attributeName = enumeration.nextElement().toString(); if (("__flexSession".equals(attributeName)) || ("currentuser".equals(attributeName))) continue; o = new TURLParameterDTO(); o.setPropertykey(attributeName); o.setPropertyvalue((String) session.getAttribute(attributeName));
上面的程式碼中拿到了session中的值.
=============================================
flex呼叫java也存在request請求,
HttpServletRequest request = FlexContext.getHttpRequest(); // flex.messaging.FlexContext
然後通過request能拿到session
HttpSession session = request.getSession(); // javax.servlet.http.HttpSession
