我在使用返回JSON字符串的API时遇到了一个问题.try 将JSON字符串响应从API转换为Map<；字符串、对象>；时，会抛出错误.但是，当我手动将相同的JSON字符串响应嵌入到我的代码中并执行到Map<；字符串、对象>；的转换时，它可以无缝地工作.事实证明，理解这种行为对我来说是相当具有挑战性的
错误:
上下文初始化期间遇到异常-正在取消刷新try :org.springframework.beans.factory.BeanCreationException:创建名为""TestService""的Bean时出错:调用init方法失败；嵌套异常为Java."异常:com.fasterxml.jackson.databind.exc.MismatchedInputException:无法构造java.util.LinkedHashMap的实例(尽管至少存在一个创建器):没有要从字符串值(‘{’)反序列化的字符串参数构造函数/工厂方法"
