如何在服务器上获取某些子报表的ReportDesign类以进行基于scriptlet的修改？

问题描述

本地我有一个 master.jrxml 报告和一些 subreport.jrxml ，可以加载和操作子报告 Scriptlet代码中的ReportDesign design = JRXmlLoader.load（/ local-file-dir/path/to/subreport.jrxml）。

Locally I have a master.jrxml report and some subreport.jrxml and can load and manipulate the subreport via ReportDesign design = JRXmlLoader.load( "/local-file-dir/path/to/subreport.jrxml" ) in the Scriptlet code.

在服务器上，上面的加载方法（由我的 master.jrxml 触发）显然无法处理回购路径，无论我做了什么（基本上 net.sf.jasperreports.engine.JRException：java.io.FileNotFoundException：... ）

On the server, the above load method (trigged by my master.jrxml) obviously cannot deal with repo paths, no matter what I tried (basically net.sf.jasperreports.engine.JRException: java.io.FileNotFoundException: ...)

（ subreport.jrxml 作为 JRXML文件资源上传 - 而非报告，具有无形创建的文件夹结构;
subreport-attached.jrxml 作为 master.jrxml的文件资源上传报告
）

(subreport.jrxml uploaded as a JRXML File Resource - not as Report with invisibly created folder structures ;subreport-attached.jrxml uploaded as a file resource of my master.jrxml Report)

• apwop）没有协议前缀的绝对回购路径，例如 /repo/path/subreport.jrxml


• apwp）具有协议前缀的绝对回购路径，例如 repo：/repo/path/subreport.jrxml


• rpwop）没有协议前缀的相对repo路径，例如 subreport-attached.jrxml


• rpwp）具有协议前缀的相对repo路径，例如 repo：subreport-attached.jrxml

• apwop) absolute repo path without protocol prefix, e.g. /repo/path/subreport.jrxml
• apwp) absolute repo path with protocol prefix, e.g. repo:/repo/path/subreport.jrxml
• rpwop) relative repo path without protocol prefix, e.g. subreport-attached.jrxml
• rpwp) relative repo path with protocol prefix, e.g. repo:subreport-attached.jrxml

我还试过以下内容在网络其他地方找到的uri变种没有成功：

I also tried the following with the above uri variants as found elsewhere in the web without success:

• JRXmlLoader ：

JRXmlLoader.load(
  new DefaultRepositoryService( 
    DefaultJasperReportsContext.getInstance() 
  ).getInputStream( subrepPath )

RepositoryUtil ：

RepositoryUtil.getInstance( 
  DefaultJasperReportsContext.getInstance() 
).getInputStreamFromLocation( subrepPath )

JasperServerUtil ：类似于我还在尝试并将报告回来（直到现在有适当的Maven jasperserver库支持的问题 - 我可以在）

• 更新：工作正常：请参阅下面的答案


• JasperServerUtil: similar to this I am still trying out and will report back (had problems with proper Maven jasperserver libraries support till now - other problem I may address in another question)
  • update: it worked: see my answer below

  推荐答案

  哇！ :)使用 com.jaspersoft.jasperserver.api.metadata.common.service.RepositoryService 的最后一种方法是这样的：

  Woohoo! :) The last approach with the com.jaspersoft.jasperserver.api.metadata.common.service.RepositoryService worked like this:

  JasperDesign design = JRXmlLoader.load(
     ( (RepositoryService) StaticApplicationContext.getApplicationContext()
       .getBean( "repositoryService" ) 
     )
     .getResourceData( JasperServerUtil.getExecutionContext() , 
       "repo:/some/where/subreport.jrxml" )
     .getDataStream()
  

  Puh！hard birth。

  Puh! hard birth.
