添加您的基本包,我想是它的控制器或其他东西。
我认为这就是问题所在。您正在使用路径ChickenTest访问url,但您在控制器中将其映射为Chicken
@RequestMapping(value=“/Chicken/indexChicken”)
将
RequestMapping
替换为ChickenTest或使用Chicken访问url@RequestMapping(value=“/Chicken/indexChicken”)您将Chicken设置为映射,但在url中使用ChickenTest非常感谢,知道我可以清楚地看到我的错误。没问题,请告诉我它是否有效,然后我将发布一个答案,这样您就可以将其标记为acceptedYes,这是正确的答案:)我发现记录Spring logger语句非常有帮助,正是因为这个原因。在应用程序启动时,Spring会记录RequestMappings(我认为日志会略有不同,具体取决于您实现的HandlerMapping)。然后,您可以将异常中列出的URI与应用程序启动时打印的RequestMappings进行比较(确切地说,控制台中的Ctrl+F)。如果你找不到的话,可能是某个地方有错别字。
