Question

我已经从raml-to-jaxrs maven plugin生成了this RAML file（2.1.1-SNAPSHOT）的类，并使用Jersey代理客户端调用服务，如下所示：

Client client = ClientBuilder.newClient();
Logger logger = Logger.getLogger(getClass().getName());
Feature feature = new LoggingFeature(logger, Level.INFO, null, null);
client.register(feature);        
client.register(new PostiSmartShipAuthenticator(username, password));
WebTarget target = client.target(URI);
Addresses proxy = WebResourceFactory.newResource(Addresses.class, target);
GetAddressesAgentsResponse response = proxy.getAddressesAgents("ITELLASP", null, "51270", null, "FI", null);

服务以一组对象响应：

INFO: 1 * Sending client request on thread main
1 > GET https://.../addresses/agents?type=ITELLASP&zip=51270&countryCode=FI
1 > Accept: application/json
1 > Authorization: Basic ...

INFO: 1 * Client response received on thread main

[{"id":"512053201","name":"Pakettiautomaatti, S-market Kangasniemi","address1":"Otto Mannisen tie 10","address2":null,"zipcode":"51205","city":"KANGASNIEMI","state":null,"countryCode":"FI","contact":null,"phone":null,"fax":null,"email":null,"sms":null,"serviceType":null,"serviceCode":null,"openingHours":"ma-la 7.00 - 21.00, su 10.00 - 21.00"},{"id":"761053201","name":"Pakettiautomaatti, K-citymarket Pieksämäki","address1":"Kukkaroniementie 3","address2":null,"zipcode":"76105","city":"PIEKSÄMÄKI","state":null,"countryCode":"FI","contact":null,"phone":null,"fax":null,"email":null,"sms":null,"serviceType":null,"serviceCode":null,"openingHours":"ma-pe 8.00 - 21.00, la 8.00 - 20.00, su 11.00 - 18.00"},{"id":"408053201","name":"Pakettiautomaatti, S-market Vaajala","address1":"Asematie 1","address2":null,"zipcode":"40805","city":"VAAJAKOSKI","state":null,"countryCode":"FI","contact":null,"phone":null,"fax":null,"email":null,"sms":null,"serviceType":null,"serviceCode":null,"openingHours":"ma-la 7.00 - 22.00, su 10.00 - 22.00"},{"id":"409053201","name":"Pakettiautomaatti, S-market Säynätsalo","address1":"Parviaisentie 6","address2":null,"zipcode":"40905","city":"SÄYNÄTSALO","state":null,"countryCode":"FI","contact":null,"phone":null,"fax":null,"email":null,"sms":null,"serviceType":null,"serviceCode":null,"openingHours":"ma-la 7.00 - 21.00, su 10.00 - 21.00"},{"id":"405253201","name":"Pakettiautomaatti, S-market Kuokkala","address1":"Syöttäjänkatu 2","address2":null,"zipcode":"40525","city":"JYVÄSKYLÄ","state":null,"countryCode":"FI","contact":null,"phone":null,"fax":null,"email":null,"sms":null,"serviceType":null,"serviceCode":null,"openingHours":"ma-la 7.00 - 23.00, su 10.00 - 23.00"}]

但是，无法将对象数组反序列化为GetAddressesAgentsResponse：

出于某种原因，即使我有

，插件似乎也会生成com.fasterxml.jackson annotations的类

<generateTypesWith>
    <value>jaxb</value>
</generateTypesWith>

pom.xml中的

。可能这不是实际问题。

目前有效的依赖关系是

javax.ws.rs:javax.ws.rs-api:2.1
org.glassfish.jersey.core:jersey-client:2.26
org.glassfish.jersey.core:jersey-common:2.26
org.glassfish.jersey.ext:jersey-proxy-client:2.26
org.glassfish.jersey.inject:jersey-hk2:2.26
org.glassfish.jersey.media:jersey-media-jaxb:2.26
org.glassfish.jersey.media:jersey-media-json-binding:2.26
org.glassfish.jersey.media:jersey-media-json-jackson:2.26
org.raml.jaxrs:jaxrs-code-generator:2.1.1-SNAPSHOT

我应该使用除地址之外的其他界面吗？

Addresses proxy = WebResourceFactory.newResource(Addresses.class, target);

应该更改什么才能使反序列化工作？

亲切的问候，

模型文件是否使用jaxb Annotations注释？（即：@XmlRootElement）
