本文介绍如何使用Java实现从JSON字符串中获取和解析考试试卷，包括问题、选项和得分。重点展示了如何通过`ExamQuestion`类处理 ExamPaper API 的调用和JSON数据转换。
@Override
public String getExamPaper(String examID, String userID) throws Exception{
String strResult;
ExamQuestion entity;
strResult = examObjectStudentRep.getExamPaper(examID, userID);
entity = JSON.parseObject(JSON.parse(strResult).toString(),ExamQuestion.class);
return examObjectStudentRep.getExamPaper(examID, userID);
}
