Summary: How to consume Odata service having self-signed
certificate using Olingo in java?
Key: OLINGO-1216
URL: https://issues.apache.org/jira/browse/OLINGO-1216
Project: Olingo
Issue Type: Question
Components: odata4-client
Affects Versions: (Java) V4 4.4.0
Environment: java, Spring boot
Reporter: Feby Baby
Priority: Blocker
I am trying to consume Redfish API which uses OData service in Java using
Spring boot application.
I understand that Olingo and Odata4j are the java libraries for consuming OData
service. I tried using Olingo but getting error as the https server is having a
self-signed certificate. Initially, I tried to access the redfish API using
RestTemplate which worked out well. But for getting @odata.id tag information,
we need to use the OData specific library.
Sample json output of Redfish API:
{
@odata.context: "/redfish/v1/$metadata#ServiceRoot.ServiceRoot",
@odata.id: "/redfish/v1",
@odata.type: "#ServiceRoot.v1_0_2.ServiceRoot",
AccountService: {
@odata.id: "/redfish/v1/Managers/iDRAC.Embedded.1/AccountService"
},
Chassis: {
@odata.id: "/redfish/v1/Chassis"
},
Description: "Root Service",
EventService: {
@odata.id: "/redfish/v1/EventService"
},
Id: "RootService",
JsonSchemas: {
@odata.id: "/redfish/v1/JSONSchemas"
},
Links: {
Sessions: {
@odata.id: "/redfish/v1/Sessions"
}
},
Managers: {
@odata.id: "/redfish/v1/Managers"
},
Name: "Root Service",
RedfishVersion: "1.0.2",
Registries: {
@odata.id: "/redfish/v1/Registries"
},
SessionService: {
@odata.id: "/redfish/v1/SessionService"
},
Systems: {
@odata.id: "/redfish/v1/Systems"
},
Tasks: {
@odata.id: "/redfish/v1/TaskService"
}
}
Code:
ODataClient client = ODataClientFactory.getClient();
String serviceUrl = "https://IP_address/redfish/v1/Systems/";;
client.getConfiguration().setHttpClientFactory(new
BasicAuthHttpClientFactory("[uname]", "[pswd]"));
URI absoluteUri = client.newURIBuilder(serviceUrl).build();
ODataEntitySetIteratorRequest<ClientEntitySet, ClientEntity> request =
client.getRetrieveRequestFactory().getEntitySetIteratorRequest(absoluteUri);
// odata4 sample/server limitation not handling metadata=full
request.setAccept("application/json;odata.metadata=minimal");
ODataRetrieveResponse<ClientEntitySetIterator<ClientEntitySet,
ClientEntity>> response = request.execute();
ClientEntitySetIterator<ClientEntitySet, ClientEntity> iterator =
response.getBody();
I am getting the following certificate related error while trying to consume
the OData service API:
[Request processing failed; nested exception is
org.apache.olingo.client.api.http.HttpClientException:
