[英]No connection to Tomcat server
我正在研究 Spring。尝试运行我的第一个简单应用程序但没有成功。 我不知道为什么,但它写道hello-world
不可用。 两天来,我一直试图了解问题所在,但我做不到。 如果有人能提供帮助,我会很高兴。
代码

应用上下文MVC

你好控制器
package ru.alishev.springcourse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
@Controller
public class HelloController {
@GetMapping("/hello-world")
public String sayHello() {
return "hello_world";
}
}
连接时的错误表明您正在尝试连接到hello_world
,但您的带注释的映射适用于hello-world
