例如，我想解析以下Json：
{
"servers": [
{
"status": "SHUTOFF",
"updated": "2014-08-05T06:42:19Z",
"hostId": "038d4d27e44754af0a4d163ab981e33930bf1a66450fa260d5459b8d",
"OS-EXT-SRV-ATTR:host": "dev-desktop"
}
]
}
我以前做过的课应该是：
public class Server
{
private String status;
private String updated;
private String hostId;
@XmlElement(name = "OS-EXT-SRV-ATTR:host")
private String OS_EXT_SRV_ATTR_host;
}
当我尝试将json转换为类时，这是Glassfish服务器的日志：

是否有任何转义字符以防止Json密钥中的冒号问题？这是第一个想到的想法，但肯定还有其他更好的方法来解决这个问题。 谢谢你的帮助！
答案 0 :(得分：0)
尝试更改命名空间分隔符：
jsonMarshaller.setProperty(MarshallerProperties.JSON_NAMESPACE_SEPARATOR, '.');
jsonUnmarshaller.setProperty(UnmarshallerProperties.JSON_NAMESPACE_SEPARATOR, '.');
我使用.，但你必须选择合适的角色。
此外，您的json servers元素是一个数组，但您的目标是一个简单的对象。只是指出来......
为了将这些功能直接设置到客户端：
final MoxyJsonConfig moxyJsonConfig = MoxyJsonConfig()
.setNamespacePrefixMapper(namespacePrefixMapper)
.setNamespaceSeparator(':');
final Client client = ClientBuilder.newBuilder()
// The line below that registers MOXy feature can be
// omitted if FEATURE_AUTO_DISCOVERY_DISABLE is
// not disabled.
.register(MoxyJsonFeature.class)
.register(jsonConfigResolver)
.build();
答案 1 :(得分：0)
我在从Akamai https://jsapi.apiary.io/apis/akamaiopen2lunapapiproduction/reference/edge-hostnames.html返回的json有效负载中遇到了同样的问题，其中一个密钥包含冒号。
基于Baldy和javadoc https://jersey.java.net/documentation/latest/media.html#json.moxy
上面的答案，经过多次试验和错误，我终于得到了它的工作您的代码需要像......
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import org.glassfish.jersey.moxy.json.MoxyJsonConfig;
import org.glassfish.jersey.moxy.json.MoxyJsonFeature;
...
ClientBuilder builder = ClientBuilder.newBuilder();
boolean initDefaultProperties = true;
MoxyJsonConfig moxyJsonConfig = new MoxyJsonConfig(initDefaultProperties);
moxyJsonConfig.setNamespaceSeparator(':');
Map<String, String> namespacePrefixMapper = new HashMap<String, String>();
namespacePrefixMapper.put("OS-EXT-SRV-ATTR", "OS-EXT-SRV-ATTR");
moxyJsonConfig.setNamespacePrefixMapper(namespacePrefixMapper);
builder.register(MoxyJsonFeature.class);
builder.register(moxyJsonConfig.resolver());
Client client = builder.build();
WebTarget target = client.target("https://www.xxxxxxx.com/restApi/v0");
WebTarget resourceWebTarget = target.path("serverStatus").queryParam("status","SHUTOFF");
Invocation.Builder invocationBuilder = resourceWebTarget.request(MediaType.APPLICATION_JSON_TYPE);
// GET ...
Response response = invocationBuilder.get();
System.out.println(response.getStatus());
System.out.println(response.getHeaders());
if (response.getStatus() == 200)
{
ServerStatusResponse statusResponse = response.readEntity(ServerStatusResponse.class);
for (Server s : statusResponse.getServers()) {
System.out.println(s.getOSEXTSRVATTRHost());
}
}
然后假设像下面这样的pojos ..检查OSEXTSRVATTRHost设置器上使用的注释......
public class Server {
private String status;
private String updated;
private String hostId;
private String OSEXTSRVATTRHost;
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getUpdated() {
return updated;
}
public void setUpdated(String updated) {
this.updated = updated;
}
public String getHostId() {
return hostId;
}
public void setHostId(String hostId) {
this.hostId = hostId;
}
public String getOSEXTSRVATTRHost() {
return OSEXTSRVATTRHost;
}
@XmlElement(namespace="OS-EXT-SRV-ATTR", name="host")
public void setOSEXTSRVATTRHost(String OSEXTSRVATTRHost) {
this.OSEXTSRVATTRHost = OSEXTSRVATTRHost;
}
}
和服务器状态响应类...
import java.util.ArrayList;
import java.util.List;
public class ServerStatusResponse {
private List<Server> servers = new ArrayList<Server>();
public List<Server> getServers() {
return servers;
}
public void setServers(List<Server> servers) {
this.servers = servers;
}
}
