如何更改首選項以便每個窗口顯示不同的內容？

我想重寫首選項的值，但沒有任何重寫。有誰知道如何解決這個問題？如何更改首選項以便每個窗口顯示不同的內容？

的portlet.xml

<?xml version="1.0" encoding="UTF-8"?> 
<portlet-app xmlns="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0" xsi:schemaLocation="http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd http://java.sun.com/xml/ns/portlet/portlet-app_2_0.xsd">

MainController.java

@RequestMapping(value = "VIEW") 
@Controller(value = "mainController") 
public class MainController { 
    @RenderMapping 
    public String init(@RequestParam(value = "key", required = false) String key, Model model, PortletRequest request) throws Exception { 
     PortletPreferences preferences = request.getPreferences(); 
     String preferencesKey = preferences.getValue("KEY", "Not Found!!!"); 
     System.out.println("KEY is : " + preferencesKey); 
     model.addAttribute("preferencesKey", preferencesKey); 
     return "index"; 
    } 
}

輸出：

13:49:54,860 INFO [STDOUT] KEY is : TEST 
13:50:21,088 INFO [STDOUT] KEY is : TEST

您是否以擁有管理員權限的用戶身份登錄？ – mod

你需要調用的setValue，然後儲存您PortletPreferences對象。請注意，首選項只能存儲在操作階段。 visit
