小白第一个springBoot启动报错

技术交流
1

再启动springBoot后， 用界面访问简单的controller的后报错，感觉是读取文件的webSocket 关闭报错，
请问各位有遇到过吗?
界面可以正常访问

@RestController
public class HelloWorldController {
@RequestMapping("/hello")
public String index() {
return “Hello World”;
}
}

问题描述不清楚，异常日志也没发到重点。

感谢回复，在做一个简单的mybatis+ spring Boot 实例的时候，通过网页访问controller后俩三秒后台报出异常
详细异常信息如下

这些异常都是Tomcat很底层的异常。属于网络连接的范畴。例如客户端的编码不规范，或者没有正常的断开连接。应用程序代码没法干预，处理。如果它不影响程序的使用。可以忽视。

好的，十分感谢
