我想在我的 Kotlin 资源文件中包含一个依赖项。但我不能。

我制作了这个教程：https : //quarkus.io/guides/rest-client-guide 但是，为了开始这个项目，我在我的项目中包含了扩展“kotlin”。

我的代码如下：

国家.kt

package org.acme.restclient

class Country {
  var name:String? = null
  var alpha2Code:String? = null
  var capital:String? = null
  var currencies:List<Currency>? = null
  class Currency {
    var code:String? = null
    var name:String?= null
    var symbol:String? = null
  }
}

国家服务.kt

package org.acme.restclient

import org.eclipse.microprofile.rest.client.inject.RegisterRestClient
import javax.ws.rs.GET
import javax.ws.rs.Path
import javax.ws.rs.PathParam
import javax.ws.rs.Produces

@Path("/v2")
@RegisterRestClient
interface CountriesService {
    @GET
    @Path("/name/{name}")
    @Produces("application/json")
    fun getByName(@PathParam("name") name: String): Set<Country>
}

国家资源.kt

package org.acme.restclient

import org.eclipse.microprofile.rest.client.inject.RestClient
import javax.inject.Inject
import javax.ws.rs.GET
import javax.ws.rs.Path
import javax.ws.rs.PathParam
import javax.ws.rs.Produces
import javax.ws.rs.core.MediaType

@Path("/country")
class CountriesResource {
    @Inject
    @RestClient
    lateinit internal var countriesService: CountriesService

    @GET
    @Path("/name/{name}")
    @Produces(MediaType.APPLICATION_JSON)
    fun name(@PathParam("name") name: String): Set<Country> {
        return countriesService.getByName(name)
    }
}

应用程序属性

org.acme.restclient.CountriesService/mp-rest/url=https://restcountries.eu/rest

有人可以帮助我吗？

谢谢！

这个问题是 Kotlin 处理注释的方式和注释定义中缺少 a 的组合@Target。@RestClient

要解决您的问题，只需使用：

   @Inject
   @field: RestClient
   lateinit internal var countriesService: CountriesService
