這是我第一次使用Spring，我正在關注PluralSight的教程。運行第一個示例，我遇到了標題中列出的錯誤。在我的控制檯中，我收到類似這樣的錯誤。我正在使用舊版本的依賴關係來完成此課程。我已經確保嚴格按照教程進行操作，所以不確定我是否搞砸了某個地方或某些東西已被棄用。我使用http://localhost:8080/FitnessTracker/greeting.htmlHTTP狀態500 - servlet的Servlet.init（）fitTrackerServlet拋出異常
SEVERE: Context initialization failed
java.lang.IllegalArgumentException
SEVERE: StandardWrapper.Throwable
java.lang.IllegalArgumentException
SEVERE: Allocate exception for servlet fitTrackerServlet
java.lang.IllegalArgumentException
HelloController.java
package com.pluralsight.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class HelloController {
@RequestMapping(value = "/greeting")
public String sayHello(Model model) {
model.addAttribute("greeting", "Hello World");
return "hello";
}
}

在您的servlet-config.xml中，嘗試刪除此行xmlns：p =「http://www.springframework.org/schema/p」和檢查 –
您所需要做的就是確保您的servlet容器的運行時是Java 7.有關詳細信息，請參閱[我的答案]（https://stackoverflow.com/a/44530401/3395831）。 – Utku
