我正在使用JaxRS创建与供应商的API交互的客户端代码。我已经能够编写执行GET和POST的代码,这两个代码都没有请求体。我目前遇到一个问题,尝试进行POST,只有一个请求正在发送。我正在尝试发送一个简单的JSON字符串:
{"server":{"name":"HelloKitty","imageId":71,"flavorId":1}}
以下是我正在使用的WebClient的定义(用Scala编写,但我知道标题和授权正在正确完成):
def postClient: WebClient = {
val authClient = WebClient.create(authServer)
authClient.header("X-Auth-User", apiUsername)
authClient.header("X-Auth-Key", apiKey)
val response = authClient.get
val metadata = response getMetadata () map { case (k, v) => k -> v(0).toString }
val client = WebClient.create(metadata.get("X-Server-Management-Url").getOrElse("Error in authentication response"))
client.header("X-Auth-User", apiUsername)
client.header("X-Auth-Key", apiKey)
client.header("X-Auth-Token", metadata.get("X-Auth-Token").getOrElse("Error in authentication response"))
client.header("Content-Type","application/json")
}
这是我的资源界面:
@Produces(Array("text/json"))
trait RackspaceServerApi {
@Path("/servers.json")
@GET
def listServers(): String
@Path("/servers/detail.json")
@GET
def listServersDetailed(): String
@POST
@Path("/servers")
@Consumes(Array("application/json"))
def createServerData(server: String)
}
这是我创建代理并尝试发送请求的方法
def createServer(name: String, imageId: Long, flavorId: Int) = {
// this creates a simple pojo for the server
val serverObject = new RackspaceCreateServerObject(name, imageId, flavorId, None, None)
// i am using lift-web to handle the json
// here I am unmarshalling the serverObject into a json string
val jsonServerData = write(serverObject)
val postProxy = JAXRSClientFactory.fromClient(RackspaceConnection.postClient, classOf[RackspaceServerApi], true)
postProxy.createServerData(jsonServerData)
}
这是我得到的特定WebApplicationException:
状态代码:[500]
实体:[没有为响应类找到消息正文编写器:JAXBElement。]
但是,如果我尝试使用webclient而不是像这样的代理发送请求:
def createServer(name: String, imageId: Long, flavorId: Int) = {
// this creates a simple pojo for the server
val serverObject = new RackspaceCreateServerObject(name, imageId, flavorId, None, None)
// i am using lift-web to handle the json
// here I am unmarshalling the serverObject into a json string
val jsonServerData = write(serverObject)
val webClient = RackspaceConnection.postClient
webClient.path("/servers")
webClient.post(jsonServerData)
}
有效。我在界面上做错了什么(缺少一些神奇的注释组合?)?或者我没有设置一些东西? 我使用的是Jax-RS 2.3.2。
答案 0 :(得分:0)
您使用的是哪种JAX-RS实现?
错误消息表明您需要注册一个插件/模块来处理JAXB bean到JSON的编组。一些JAX-RS实现会自动执行此操作,有些需要初始化。
