自訂處理中報表 custom-reports-in-process-reporting
您可以使用QueryBuilder的REST介面,或使用QueryBuilder API建立OSGi服務以建立自訂報表。
建立自訂報表的一般步驟 generic-steps-to-build-a-custom-report
新增任何自訂報表之前,請執行下列範本程式:
-
自訂報表中使用的資料必須可在「處理報告」中使用。 為確保資料的可用性,請排程cron作業或使用 同步 選項。
-
URL要求(封裝所需的查詢)必須傳回適當的查詢結果物件。 若要建立查詢,您可以使用 QueryBuilder 使用QueryBuilder API建立OSGi服務。 您可以建立動態或靜態查詢。
-
建立自訂使用者介面以顯示結果。 您可以建立獨立的用戶介面,或將結果與現有的「流程報告」UI整合。
使用QueryBuilder的REST介面 using-the-rest-interface-of-the-querybuilder
CRX QueryBuilder REST介面會透過Java API和REST API公開「資產共用查詢產生器」的功能。 了解如何使用 CRX QueryBuilder REST介面,然後再執行下列步驟:
-
瀏覽至URL
https://[server]:[port]/lc/bin/querybuilder.json
-
根據Process Reporting儲存節點結構和節點屬性建立查詢。
您可以指定選用參數來指定位移、限制、點擊和屬性。 您可以硬式編碼靜態報表的引數,並從動態報表的UI擷取參數。
若要擷取所有程式名稱,查詢為:
https://[Server]:[Port]/lc/bin/querybuilder.json?exact=false&p.hits=selective&p.properties=pmProcessTitle&path=%2fcontent%2freporting%2fpm&property=pmNodeType&property.operation=equals&property.value=ProcessType&type=sling%3aFolder
note note NOTE 在每個查詢中,路徑參數會指向crx儲存位置,而字元會根據URL標準逸出。
使用查詢產生器API建立服務 creating-a-service-using-query-builder-api-nbsp
使用查詢產生器API建立服務的先決條件為 建立和部署CQ OSGI套件組合 和 使用查詢產生器API.
-
建立包含適當註解的OSGi服務。 若要存取QueryBuilder,請使用:
code language-none @Reference(referenceInterface = QueryBuilder.class) private QueryBuilder queryBuilder;
-
建立謂語組。 建立謂語群組的程式碼為:
code language-none PredicateGroup predicateGroup = new PredicateGroup(); predicateGroup.setAllRequired(true);
-
將謂詞添加到新建立的謂片語。 一些有用的謂詞結構包括 JcrBoolPropertyPredicateEvaluator, JcrPropertyPredicateEvaluator, RangePropertyPredicateEvaluator, DateRangePredicateEvaluator,和 TypePredicateEvaluator.
若為靜態報表,會以硬式編碼撰寫述詞,若為動態報表,則從請求擷取述詞。
取得程式所有例項的程式碼範例為:
code language-java Predicate predicate; //Add the path Constraint predicate = new Predicate(PathPredicateEvaluator.PATH); predicate.set(PathPredicateEvaluator.PATH, "/content/reporting/pm"); // should point to the crx path being used to store data predicate.set(PathPredicateEvaluator.EXACT, "false"); predicateGroup.add(predicate); //type nt:unstructured predicate = new Predicate(TypePredicateEvaluator.TYPE); predicate.set(TypePredicateEvaluator.TYPE, "nt:unstructured"); predicateGroup.add(predicate); //NodeType: Process Instance predicate = new Predicate(JcrPropertyPredicateEvaluator.PROPERTY); predicate.set(JcrPropertyPredicateEvaluator.PROPERTY, "pmNodeType"); predicate.set(JcrPropertyPredicateEvaluator.OPERATION, JcrPropertyPredicateEvaluator.OP_EQUALS); predicate.set(JcrPropertyPredicateEvaluator.VALUE, "ProcessInstance"); predicateGroup.add(predicate); //processName predicate = new Predicate(JcrPropertyPredicateEvaluator.PROPERTY); predicate.set(JcrPropertyPredicateEvaluator.PROPERTY, "pmProcessName"); predicate.set(JcrPropertyPredicateEvaluator.OPERATION, JcrPropertyPredicateEvaluator.OP_EQUALS); predicate.set(JcrPropertyPredicateEvaluator.VALUE, processName); //processName variable stores the name of the process whose instances need to be searched predicateGroup.add(predicate);
-
使用predicateGroup定義查詢。
Query query = queryBuilder.createQuery(predicateGroup, session);
-
獲取查詢的結果。
code language-java query.setStart(offset); // hardcode or fetch from request if(hits == -1) // hardcode or fetch from request hits = 0; query.setHitsPerPage(hits); SearchResult searchResult = query.getResult();
-
迭代結果,並將結果轉換為所需格式。 以CSV格式傳送結果的程式碼為:
code language-java Iterator<Node> iter = searchResult.getNodes(); while(iter.hasNext()) { Node node = iter.next(); row = new StringBuilder(); for (String property : includeProperties) { // the properties of the node which needs to be returned, or one can return all the properties too. try { row.append(node.getProperties(property).nextProperty().getString() + COMMA_SEPARATOR); } catch (NoSuchElementException e) { //Adding separator for no value row.append(COMMA_SEPARATOR); } catch (RepositoryException e) { e.printStackTrace(); } } row.deleteCharAt(row.lastIndexOf(COMMA_SEPARATOR)); row.append(NEW_LINE); out.write(row.toString().getBytes());
-
使用
org.apache.felix maven-bundle-plugin
為servlet建立OSGi套件組合。 -
在CRX伺服器上部署套件組合。

建立個別UI creating-a-separate-ui-nbsp
建立個別UI以顯示結果的先決條件為 Sling基本介紹, 建立CRX節點 提供適當 訪問權限.
-
在
/apps
節點和授予適當的存取權限。 (PERM_PROCESS_REPORTING_USER) -
在
/content
節點。 -
將JSP或HTML檔案添加到在步驟1中建立的節點。 您也可以新增CSS檔案。
包含JSP和CSS檔案的示例節點
-
新增javascript程式碼,以啟動對查詢建立器REST API或您的服務的Ajax呼叫。 另外,添加適當的參數。
-
將適當的成功處理常式新增至Ajax呼叫,以剖析並顯示結果。 您可以剖析結果為多種格式(json/csv/user defined),並以表格或其他格式顯示。
-
