排查前端接受后端的map产生的字段错误

报错内容

[Request processing failed; nested exception is org.thymeleaf.exceptions.TemplateProcessingException: Exception evaluating SpringEL expression: "map.likeCount" (template: "/index" - line 151, col 67)] with root cause

Property or field 'likeCount' cannot be found on object of type 'java.util.HashMap' - maybe not public or not valid

之前就遇到过这样的问题,又出现了,所以进行排查总结一下

最终在后端控制器发现传递的数大小写写错了
