Spring boot 本地主机上的白标签错误页：8080\SendMessage？

我刚刚用Twilio启动了Springboot，但由于某些原因，当我运行localhost\sendMessage命令时，我得到了白色标签错误页面。当我运行以下代码时，测试成功结束：

package com.example.demo

import org.springframework.web.bind.annotation.RestController
import org.springframework.web.bind.annotation.RequestMapping


@RestController
public class SMSController{
    @RequestMapping( "/")
    fun helloSpringBoot() = "Hello Spring Boot!"

}

这是上述代码的结果：

但是当我使用localhost:8080\sendMessage运行下面的代码时，我得到了代码后面的屏幕截图：

package com.example.demo

import org.springframework.web.bind.annotation.RestController
import org.springframework.web.bind.annotation.RequestMapping
import com.twilio.http.TwilioRestClient
import com.twilio.rest.api.v2010.account.MessageCreator
import com.twilio.type.PhoneNumber


@RestController
public class SMSController{
    @RequestMapping("/sendMessage")
    fun sendMessage(){

        val client = TwilioRestClient.Builder(
                System.getenv("ACCOUNT_SID"),
               System.getenv("AUTH_TOKEN")).build()

        val message = MessageCreator(
                PhoneNumber(System.getenv("+1..........")),
                PhoneNumber("+1.........."),
                "Lambda is annoying..Sigh"
        ).create(client)

    }

}

我错过什么了吗

我已添加我的堆栈跟踪：

我回顾了Kotlin文档，而不是专注于教程，并做了必要的更改。一旦完成，代码就开始正常工作。见以下更改：

@RestController
public class SMSController{

    @RequestMapping(value = ["/sendMessage"])
    fun sendMessage(){

        val client = TwilioRestClient.Builder("ACCOUNT_SID",
              "AUTH_TOKEN").build()

        val message = MessageCreator(
                PhoneNumber("+1........"),
                PhoneNumber("+1........"),
                "Lambda is annoying..Sigh").create(client)

    }
}

---

我假设您实际使用的是localhost:8080/sendMessage，请注意正斜杠。您能否从控制台提供任何堆栈跟踪，您的错误很可能就在那里。@matthew.kempson stack trace已添加
