正如标题所示,当我键入地址时 http://localhost:8080/dsh
,我得到以下回应:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404).
No message available
我试过了 @ComponentScan(basePackages= {"com.mps.expert.controller"})
在SpringBoot应用程序中,我尝试了许多其他解决方案,但都没有成功。我好像找不到问题。
我的 application.properties
文件为空。
这是项目结构:
这是你的电话号码 ExpertApplication.java
:
package com.mps.expert;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackages= {"com.mps.expert.controller"})
public class ExpertApplication {
public static void main(String[] args) {
SpringApplication.run(ExpertApplication.class, args);
}
}
这是控制器 dsh.java
:
package com.mps.expert.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class dsh {
@GetMapping("/dsh")
public String plot(Model mdl) {
return "dashboard";
}
}
这是 pom.xml
:
