我正在使用Spring boot + GrapQL构建一个简单的示例

package com.example.graphql

import org.springframework.boot.autoconfigure.SpringBootApplication
import org.springframework.boot.runApplication
import org.springframework.graphql.data.method.annotation.QueryMapping
import org.springframework.web.bind.annotation.RestController

@SpringBootApplication
class GraphqlApplication

fun main(args: Array<String>) {
    runApplication<GraphqlApplication>(*args)
}

@RestController
class MyQueryController {

    @QueryMapping
    fun message(): Message = Message("1","some-text")

}

data class Message(var id: String, var text: String) {
}

然后我在src/main/resources/graphql/schema. graphqls下得到了这个模式，如下所示

type Query {
    message: Message
}
type Message {
    id: String
    text: String
}

当我尝试访问http：//localhost：8080/graphql时，我得到[95221568 - 1]已完成405方法不允许，标题= {masked}
有线索吗？
这是pom.xml中的依赖项
