Pentaho 5.3 - 如何读取 PRPT 文件中的属性 [英] Pentaho 5.3 - How to read a property in PRPT files

问题描述

我需要在属性文件中设置一个值，然后在 Pentaho 5.3 的 PRPT 中读取这个值.如果我理解它，添加我的属性的文件是 design-tools/report-designer/resources/classic-engine.properties(报表设计器)和 server/biserver-ee/tomcat/webapps/pentaho/WEB-INF/classes/classic-engine.properties(BI 服务器，一旦发布).对吗?如果是这样，你能告诉我如何在我的 PRPT 文件中读取这个值(例如，pentaho.images.path=c:/myProject/images/)?如果没有，你能告诉我怎么做吗?谢谢！

I need to set a value in a properties file and then read this value in a PRPT in Pentaho 5.3.If I understand it, the file where to add my property is design-tools/report-designer/resources/classic-engine.properties (Report Designer) and server/biserver-ee/tomcat/webapps/pentaho/WEB-INF/classes/classic-engine.properties (BI server, once published).That's right? If so, could you tell me how I can read this value (example, pentaho.images.path=c:/myProject/images/) in my PRPT file? If not, could you explain to me how to do? Thank you!

推荐答案

我找到了一个解决方案...如果对某人有用，我会写下来.有问题的文件是正确的.我们需要在 classic-engine.properties 中写入:

I found a solution... I write it if that can be useful to someone. Files listed in question are correct. We need write in classic-engine.properties:

org.pentaho.reporting.engine.classic.core.environment.pentahoImgPath=c:/myProject/images/
org.pentaho.reporting.engine.classic.core.env-mapping.pentahoImgPath=env\:\:pentahoImgPath

重新启动报表设计器.现在，我们在用报表设计器打开后在 PRPT 文件中有一个新的环境变量 env::pentahoImgPath该值包含在org.pentaho.reporting.engine.classic.core.environment.pentahoImgPath"键(c:/myProject/images/)中.再见.

Restart the Report Designer. Now, we have a new environment variable in PRPT file once opened with the Report Designer, env::pentahoImgPath The value is contained in "org.pentaho.reporting.engine.classic.core.environment.pentahoImgPath" key (c:/myProject/images/). Bye.
