【问题描述】：
日志审计方法试图将复杂的 json 字符串转换为 map 以将数据以 json 的形式存储到 dynamodb 表中，但以错误 java.lang.ClassCastException: java.util.ArrayList cannot be cast to com.amazonaws.services.dynamodbv2 结尾。模型.属性值
类审计服务{
@Autowired
AuditRepository auditRepository;
ObjectMapper mapper = new ObjectMapper();
public void logAudit(HttpServletRequest httpServletRequest, HttpServletResponse servletResponse) {
Audit audit= new Audit();
// coverting complex json string to map with help of mapper
audit.setEncryptedRequest(mapper.readValue(complex_multiLevel_json_String, new TypeReference<Map>() {})
audit.save();
}

public void setEncryptedPiiRequest(Map<String, AttributeValue> encryptedRequest) {
this.encryptedRequest = encryptedRequest;

complex json string which need to store into dynamo db table in the form of map:
注意：我们不想创建具有以下 json 属性作为字段的模型类，然后将这些模型类存储到 dynamo db
