我正在使用Tomcat 10.1，Maven和Eclipse IDE制作Spring应用程序。我运行我的应用程序并查看index.jsp，但如果我输入路径“/refer”，（从GetMapping（“/refer”）），我想得到 hello_world.html，但得到错误消息：“请求的资源[/lab 57/refer]不可用”，描述：源服务器没有找到目标资源的当前表示，或者不愿意透露存在的表示。
我重新安装了Tomcat，问题没有解决，所以我真的不明白是什么问题？我的代码和项目结构：
x1c 0d1x的数据

HelloController.java

package ru.autoportal.lab;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {
  
  @GetMapping("/refer")
  public String sayHello() {
    return "hello_world";
  }
}

Spring 5不能在Tomcat 10上工作，但Spring 6可以，因为Tomcat 10和Spring 6发生了名称更改，将javax包重命名为jakarta。
如果你想使用Spring 5运行你的应用程序，你需要将你的Tomcat降级到版本9。
如果你想使用Spring 6运行你的应用程序，你需要Tomcat 10和至少JDK 17。
由于软件包重命名时发生的破坏性更改，这两者之间没有中间地带。
另外，我注意到您在pom.xml中使用了JDK 7，（1.7），我还建议你至少使用JDK 8，因为这是一个常见的JDK，用于Spring 5项目旁边的JDK 11，这两者之间的唯一区别是，如果你使用JDK 11，你将需要添加一些额外的jar时，使用Spring和Hibernate，但是如果你使用的是JDK 8（1.8），你就不必这样做了。
下面是Hibernate与JDK 11一起运行所需的依赖项列表，如果您决定使用它而不是JDK 8。

javax.activation-1.2.0.jar
jaxb-api-2.3.0.jar
jaxb-core-2.3.0.jar
jaxb-impl-2.3.0.jar
