问题内容

当我尝试对Spring Boot服务进行Rest调用时遇到了此异常。是什么导致此异常?

信息

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

描述

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

例外

@RestController
public class MainController {

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

}

问题答案:

(1)在控制器中,您不需要这样做

return "###";

(2)移除

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

因为里面

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

已经包括spring-web依赖性。
