代码

@RestController
public class MainController {

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

}

Answer 1

(1) 在 Controller 中，你不会那样做

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>

已经包含了 spring-web 依赖。
