java Maven spring未解析符号
尝试在spring framework上运行一个简单的应用程序时,我在导入web包时遇到了一个问题:
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
我的代码非常基本,我只是想发回一个简单的txt
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.bind.annotation.RequestMapping;
@SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
AppServerHandler handler = AppServerHandler.getInstance(6666);
}
@RequestMapping(value = "/",method = POST) <--- not familiar with annonation
public String index() {
return AppServerHandler.getWelcomeMsg();
}
}

我真的很想知道会出什么问题。 谢谢

请在你的课堂上加入@RestController,如下所示
@GetMapping具有HTTP方法GET
