我是java和springboot的新手。我只想运行一个简单的springboot应用程序。
环境：intellji社区版
我已经尝试了一切。 file-invalidatecahes /重启，指定控制器的基本包。但似乎没有任何作用
尝试在浏览器中打开本地主机时出错：
[This localhost page can’t be found
No webpage was found for the web address: http://localhost:8088/hello
Search Google for localhost 8088 hello
HTTP ERROR 404][1]
我的控制器：
package com.example.demo1.Controller;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class DemoController {
@RequestMapping(value = "/hello", method = RequestMethod.GET)
public String ram(){
return "success the app is working";
}
}
我的主要方法：
package com.example.demo1;
import com.example.demo1.Controller.DemoController;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
@ComponentScan(basePackageClasses = DemoController.class)
public class Demo1Application {
public static void main(String[] args) {
System.out.println("hi iam here 123");
SpringApplication.run(Demo1Application.class, args);
}
}
运行日志/堆栈跟踪：
hi iam here 123
