我的目标是在Web应用程序中生成报告。我使用Web服务使用Birt运行报告。该构建可以在我的本地计算机上正常工作，但是一旦部署了应用程序，该文档的生成将停止工作。
我将Tempaltes（rptdesign）作为字节[]存储在数据库中，我的Web服务执行以下操作： ->获取：*报告Templte的标识符（所选报告） *格式（pdf，html ...） *参数（在我的情况下，所有报告中只有一个参数）
->配置和引擎（Birt Enfine） ->返回结果
应用程序是使用Jhipster（Angular，Spring）创建的。
“我的班级”的结构：
ReportTemplate |
-- -- -- -- -- -- > dto |
| -- -- -- > AppException.java |
| -- -- -- > Report.java |
|
-- -- -- -- -- -- > services |
| -- -- -- > ReportService.java |
|
|
-- -- -- > impl |
| |-- -- -- > ReportServiceImpl.java
-- -- -- - > ReportService.java |
|
|-- -- -- -- -- -- > ReportTemplateWebService.java
对ReportTemplateWebService进行分类，生成报告的Web服务为“ generateTemplate”：
