错误信息json parse error: cannot deserialize instance of java.lang.string out of start_array token表示在JSON解析过程中,JSON解析器期望得到一个字符串(java.lang.String)类型的值,但是却遇到了一个数组(由start_array标记开始)类型的值。这通常发生在JSON数据的结构与预期的Java对象结构不匹配时。 2. 常见原...

最近在代码迁移过程中,遇到了JSON解析失败的问题。具体表现为出现 "Cannot deserialize instance ofjava.lang.Stringout of START_OBJECT token" 错误。经过仔细研究和调试,发现问题的根源在于之前使用的 fastjson 转换库被替换为 jackson 后无法正确读取数据。
