在我的 Xpages 應(yīng)用程序中，我有一個(gè) java 類(lèi)，我想在其中將 Document 設(shè)置為全局屬性并在我的方法中重用。該文檔代表一個(gè) Notes 配置文檔，我只想執(zhí)行一次查找。不幸的是，它沒(méi)有按預(yù)期工作。也許有人可以指導(dǎo)我正確的過(guò)程？首先，我設(shè)置了一個(gè)托管 bean：<managed-bean>    <managed-bean-name>emplDataMining</managed-bean-name>    <managed-bean-class>se.bank.employeeApp.utils.EmployeeDataMining</managed-bean-class>    <managed-bean-scope>view</managed-bean-scope></managed-bean>我的課程包含幾種將轉(zhuǎn)到不同系統(tǒng)的方法。系統(tǒng)的所有 URL 都存儲(chǔ)在 Notes 配置文檔中，我只想加載一次并在這些方法中重復(fù)使用public class EmployeeDataMining implements Serializable{    private static final long serialVersionUID = 1L;    private Document configuration;    //constructor class. not so very special, so I wont post it    public void getConfiguration(){        //setting up database and view        //only 1 document stored in the view so I can hard-code the reference        configuration = vw.getDocumentByKey("ConfigDocument", true);        //... rest of code e.g. setting up httpclient, JSONobj    }    public void collectDataFromSystemX(CloseableHttpClient httpclient, Employee employee, JSONObject JSONobj){        //I wont post all of my code          HttpPost httpPost = new HttpPost(this.configuration.getItemValueString("urlSystemX"));        //this.configuration is null :-?        //..rest of code    }    public void collectDataFromSystemY(CloseableHttpClient httpclient, Employee employee, JSONObject JSONobj){        //I wont post all of my code          HttpPost httpPost = new HttpPost(this.configuration.getItemValueString("urlSystemY"));        //this.configuration is null :-?        //..rest of code    }}我的代碼是從 SSJS 發(fā)起的：emplDataMining.getConfiguration(); emplDataMining.collectDataFromSystemX(//passing in the variables which are setup in getConfiguration method)所以我主要擔(dān)心的是配置文件 Document 沒(méi)有正確設(shè)置或在方法之間交換。有人能告訴我我忽略了什么嗎？
