java.lang.Thread.run(Thread.java:745) 可以看出来，主要的错误是： typeMismatch.news.newsTime,typeMismatch.newsTime,typeMismatch.java.util.Date,typeMismatch 也就是，前台传回的newsTime值的类型转换出错了。 检查之后，发现出错的原因是： 在News实体中，将newsTime字段定义为了Date类型，但是，在前端传回的值，是一个String类型，所以，发生了错误。 修正的方式为： 在News实体的newsTime字段前，加上注解： @DateTimeFormat(pattern = "yyyy-MM-dd") private Date newsTime; 即，将前端传回的yyyy-MM-dd类型的字符串，自动转换成Date格式。这样，就不会报错了
还没有评论，来说两句吧...
