RESTEASY003145:找不到内容类型为text / xml的MessageBodyReader; charset = UTF-8

标签: kotlin client resteasy jackson2

我是REST服务的新手,但是我发现的所有解决方案都是由于缺少必要的提供程序。

依赖项:

compile group: 'org.jboss.resteasy', name: 'resteasy-client', version: '3.6.1.Final'
compile group: 'org.jboss.resteasy', name: 'resteasy-jackson2-provider', version: '3.6.1.Final'
compile "com.fasterxml.jackson.module:jackson-module-kotlin:2.9.+"
compile "com.fasterxml.jackson.dataformat:jackson-dataformat-xml:2.9.+"

数据类:

@JacksonXmlRootElement(localName = "Response")
data class ResponseSessionInit(@JacksonXmlProperty(localName = "Error") val error: Error)
data class Error(@JacksonXmlProperty(localName = "Text", isAttribute = true) val text: String)

代理:

interface L3Client {

  @POST
  @Consumes("text/xml;charset=UTF-8")
  @Produces("text/xml; charset=UTF-8")
  fun test(string: String): ResponseSessionInit
}

代理方法调用:

    val proxy = client.target(API).proxyBuilder(L3Client::class.java).build()
    println(proxy.test("<Request><ProtocolInfoGet/></Request>"))

我收到例外:

javax.ws.rs.client.ResponseProcessingException: javax.ws.rs.ProcessingException: RESTEASY003145: Unable to find a MessageBodyReader of content-type text/xml;charset=UTF-8 and type class ru.abinet.commons.cft.L3.messages.ResponseSessionInit

at org.jboss.resteasy.client.jaxrs.internal.proxy.ClientProxy.invoke(ClientProxy.java:76)
at com.sun.proxy.$Proxy19.test(Unknown Source)

Resteasy客户端确实找不到XML的解码器,但我确实在路径中。

我可以更改test()方法以返回String并使用类似的东西成功解析XML

    val mapper = XmlMapper()
    mapper.registerModule(KotlinModule())
    val value = mapper.readValue(xml, ResponseSessionInit::class.java)

但是,我想自动完成。我想念的是什么?

1 个答案:

答案 0 :(得分:0)

Reasteasy无法使用jackson-xml开箱即用地处理application / xml内容类型。因此,想法是自己编写。

@Provider
@Consumes(MediaType.TEXT_XML, MediaType.APPLICATION_XML)
class BodyReaderProvider : MessageBodyReader<Any> {

   //jackson instantiation and some check code here
}

并注册

val client = ResteasyClientBuilder.newBuilder()
               .register(BodyReaderProvider())
