Spring Boot：處理程序調度失敗;嵌套的異常是java.lang.NoSuchMethodError

Question

當我嘗試對Spring引導服務執行休息調用時遇到此異常。什麼導致這個異常？

消息

Handler dispatch failed; nested exception is java.lang.NoSuchMethodError: org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod.getResponseStatus()Lorg/springframework/http/HttpStatus; 

說明

The server encountered an unexpected condition that prevented it from fulfilling the request.

代碼

@RestController 
public class MainController { 

    @RequestMapping(value = "/index", method = RequestMethod.GET) 
    public String index() { 
     return "###"; 
    } 

} 

Answer 1

（1）在控制器，你不這樣做

return "###"; 

（2）拆下

<dependency> 
    <groupId>org.springframework</groupId> 
    <artifactId>spring-web</artifactId> 
    <version>4.3.7.RELEASE</version> 
</dependency> 

因爲裏面有

<dependency> 
    <groupId>org.springframework.boot</groupId> 
    <artifactId>spring-boot-starter-web</artifactId> 
</dependency> 

已包括spring-web依賴關係。
