刚学Java 做项目时报了一个错误 一时间看的莫名其妙

EL1008E: Property or field 'createTime' cannot be found on object of type 'java.util.HashMap' - maybe not public or not valid?

随即向上排查至第一个报错，发现是thymeleaf渲染时报错。

Exception processing template "/site/notice": An error happened during template parsing (template: "class path resource [templates//site/notice.html]")

找到controller中相应方法处排查。

@RequestMapping(path = "/notice/list", method = RequestMethod.GET)

发现因为一时手滑加上自己对Java不熟悉导致找bug找了一个多小时。
