Test.java:14行 是Java Swing界面吗，能否贴出相关代码
com.itfanr.IDCard.ResultInfo() 方法是什么权限呢？设置为public再试试。
exports com.itfanr.IDCard" to module com.google.gson把你的代码发出来看看n
是解析JSON文件的问题么

这个错误是因为在模块Swing中没有将com.itfanr.IDCard导出到模块com.google.gson中，所以com.google.gson无法访问com.itfanr.IDCard.ResultInfo类。这个错误是InaccessibleObjectException，它是一个反射异常，表示正在尝试访问的对象或方法无法访问。
