Java：生成JSON：如何摆脱 - 生成不完整的JSON

Question

在下面的Java代码中，我试图生成JSON，它应该如下所示： 在运行程序时，我得到以下异常：
更新：我刚刚解决了我的问题，以下异常消失了：更新的代码在下面
第50行：对应于下面列出的Java代码中的 generator.close（）

Exception in thread "main" javax.json.stream.JsonGenerationException: Generating incomplete JSON
    at org.glassfish.json.JsonGeneratorImpl.close(JsonGeneratorImpl.java:509)
    at com.myhome.myapp.GenerateJson.main(GenerateJson.java:50)

有人能指出我在弄乱代码的地方以及如何纠正它吗？非常感谢。
