1. Previously, the jar package of jasper report was directly embedded in the project, then the sql query was executed in the project, and then the result was converted into json format and submitted to the report
2. Later, it was found that jasper server was very convenient to achieve hot deployment of reports, but the test only found that get passed parameter, but did not find json format submission field
3. If you have used jasper server or have this convenient information, please give me a code or address
