推荐答案

javax.json api（在JSON Processing API jar中提供）仅适用于编译应用程序。

The javax.json api (provided in the JSON Processing API jar) is good only for compiling the application.

如果要运行应用程序，则需要下载 JSON处理RI jar ，如下所述： https://jsonp.java.net/download.html

If you want to run the application, you have to download the JSON Processing RI jar, as explained here: https://jsonp.java.net/download.html

JSON Processing RI jar包含你缺少的org.glassfish.json.JsonProviderImpl类。

The JSON Processing RI jar contains the org.glassfish.json.JsonProviderImpl class you are missing.
