使用spring mvc實現restful api時遇到了問題。404未找到使用郵遞員的Spring MVC
我用郵遞員來測試一個方法是這樣的：
http://localhost:8080/Test/countryController/getAllCountries
- 測試是項目的名稱
- countryController是@RequestMapping的控制器類的價值
- getAllCountries是get方法
但是，我得到一個錯誤信息：
源服務器沒有找到當前表示目標 資源或者是不願意透露的一個存在。
我搜索了很多帖子，但仍然無法解決它。希望任何人都可以幫助我。
以下是下面的代碼。
