正在报告中的自定义报表 custom-reports-in-process-reporting
您可以使用QueryBuilder的REST接口，或使用QueryBuilder API创建OSGi服务以创建自定义报表。
构建自定义报表的常规步骤 generic-steps-to-build-a-custom-report
在添加任何自定义报表之前，请执行以下模板过程：
-
自定义报表中使用的数据必须在流程报表中可用。 为确保数据的可用性，请计划cron作业或使用“进程报表”UI上的 同步 选项。
-
URL请求（封装所需的查询）必须返回相应的查询结果对象。 若要创建查询，可以使用QueryBuilder的REST接口使用QueryBuilder API创建OSGi服务。 您可以创建动态或静态查询。
-
创建自定义用户界面以显示结果。 您可以创建一个独立的用户界面，或将结果与现有的Process Reporting UI集成。
使用QueryBuilder的REST接口 using-the-rest-interface-of-the-querybuilder
CRX QueryBuilder REST接口通过Java API和REST API公开资产共享查询生成器的功能。 了解如何在执行以下步骤之前使用CRX QueryBuilder REST接口：
-
浏览到URL
https://'[server]:[port]'/lc/bin/querybuilder.json -
根据Process Reporting存储节点结构和节点属性创建查询。
您可以指定可选参数以指定偏移、限制、点击和属性。 您可以对静态报表的参数执行硬编码，并从UI中获取动态报表的参数。
要获取所有进程名称，查询为：
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%3aFoldernote note NOTE 在每个查询中，path参数都指向crx存储位置，并且字符根据URL标准进行转义。
使用查询生成器API创建服务 creating-a-service-using-query-builder-api-nbsp
使用查询生成器API创建服务的先决条件是使用查询生成器API创建和部署CQ OSGI捆绑包和🔗。
-
创建包含相应注释的OSGi服务。 要访问QueryBuilder，请使用：
code language-java @Reference(referenceInterface = QueryBuilder.class) private QueryBuilder queryBuilder; -
创建谓词组。 创建谓词组的代码为：
code language-java PredicateGroup predicateGroup = new PredicateGroup(); predicateGroup.setAllRequired(true); -
将谓词添加到新创建的predicateGroup。 一些有用的谓词构造包括： JcrBoolPropertyPredicateEvaluator（位于5.3中）、JcrPropertyPredicateEvaluator（位于5.3中）、RangePropertyPredicateEvaluator（位于5.3中）、DateRangePredicateEvaluator（位于5.3中）和TypePredicateEvaluator(位于5.3中。
对于静态报表，对谓词进行硬编码；对于动态报表，从请求获取谓词。
用于获取进程所有实例的示例代码为：
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定义查询。
Query query = queryBuilder.createQuery(predicateGroup, session); -
获取查询结果。
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(); -
对结果进行迭代，并将结果转换为所需的格式。 以CSV格式发送结果的代码为：
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为servlet创建OSGi捆绑包。 -
在CRX服务器上部署该捆绑包。

创建单独的UI creating-a-separate-ui-nbsp
创建单独的UI以显示结果的先决条件是： 5.6.1中的Sling基础知识创建CRX节点并提供适当的访问权限。
-
在
/apps节点处创建一个CRX节点并授予适当的访问权限。 (PERM_PROCESS_REPORTING_USER) -
在
/content节点处定义渲染器。 -
将JSP或HTML文件添加到步骤1中创建的节点。 您还可以添加CSS文件。
包含JSP和CSS文件的示例节点
-
添加JavaScript代码以启动对querybuilder REST API或您的服务的Ajax调用。 另外，添加适当的参数。
-
向Ajax调用添加适当的成功处理程序以解析和显示结果。 您可以采用多种格式（json/csv/用户定义）来解析结果，并以表格或其他形式显示结果。
-
（可选）向Ajax调用添加适当的错误处理程序。
同时使用OSGi服务和QueryBuilder API的JSP代码示例为：

在现有的进程报告UI中集成报告UI integrating-report-ui-in-existing-process-reporting-ui-nbsp
创建单独的UI以显示结果的先决条件是Sling基础知识、创建CRX节点并提供适当的访问权限。
-
创建单独的UI。
-
在每个可插拔报表的
/content/process-reporting-runtime/custom-reports节点处创建一个子nt:unstructured节点。- id — 指定报表的唯一标识号。
- name — 指定报告的名称。 该名称会显示在UI中。
- link — 指定指向单独UI渲染程序的相对链接。 在第1步中会创建链接。
- description — 指定报告的一行说明。 您可以将描述字段留空。
- 图标 — 指定要以图形方式表示报表的图像。 您可以将图标字段留空。
节点的属性
-
报表UI已集成到流程报表UI。 集成UI后，更新的UI类似于以下图像：
新添加的自定义报告的
新添加的自定义报表的用户界面
自定义报告的“结果”屏幕
示例包 sample-package
将sample-report-pkg-1.zip包导入到进程管理UI中，以将文章中讨论的自定义报表和UI集成在一起。
