Dear all:
I use java api to access contrail config, but java api can't
deserialize VirtualRouter due to virtual_router_type's type doesn't
match between database and vnc_cfg.xsd.
test code: -------------->
package test_vrouter;
import java.io.IOException;
import net.juniper.contrail.api.ApiConnector;
import net.juniper.contrail.api.ApiConnectorFactory;
import net.juniper.contrail.api.types.VirtualRouter;
public class Test {
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
ApiConnector api = ApiConnectorFactory.build("10.10.7.208",
8082)
.credentials("admin", "admin").tenantName("admin")
.authServer("keystone", "http://10.10.7.208:5000/v2.0";);
VirtualRouter vr =
(VirtualRouter)api.findById(VirtualRouter.class,
"068f26d9-1704-4030-b1ed-6dee2a608d2d");
vr.setDisplayName("ubuntu208-1");
api.update(vr);
System.out.println(vr.toString());
}
}
exception stack: ------------>
Exception in thread "main" com.google.gson.JsonSyntaxException:

... 8 more
the cause is Gson can't deserialize VirtualRouter from it's json
representation: ---------->
{"virtual-router": {"fq_name": ["default-global-system-config",

"10.10.7.208", "name": "ubuntu208"}}
the virtual_router_type is a empty array [], but it's declared as
String in vnc_cfg.xsd:---------->
966 <xsd:simpleType name="VirtualRouterType">
967 <xsd:restriction base="xsd:string">
968 <xsd:enumeration value="embedded"/>
969 <xsd:enumeration value="tor-agent"/>
970 <xsd:enumeration value="tor-service-node"/>
971 </xsd:restriction>
972 </xsd:simpleType>
973
974 <xsd:element name="virtual-router-type" type="VirtualRouterType"/>
975 <!--#IFMAP-SEMANTICS-IDL
976 Property('virtual-router-type', 'virtual-router') -->
and the generated java source decares virtual_router_type as String:
---------->
14 public class VirtualRouter extends ApiObjectBase {
15 private String virtual_router_type;
I change it to private List<String> virtual_router_type or just
remove it from Virtualrouter, the test code can succeed.
I digest into source code, and found that the virtual_router_type is
stored in cassandra as a list, and vnc_cfg_api_server doesn't touch it
And I find out that it's writed to from
./contrail-web-controller/webroot/config/physicaldevices/virtualrouters/ui/js/virtualrouters_config.js:
---------->
postObject["virtual-router"] = {};
postObject["virtual-router"]["fq_name"] =
["default-global-system-config", name];
postObject["virtual-router"]["parent_type"] =
"global-system-config";
postObject["virtual-router"]["name"] = name;
postObject["virtual-router"]["virtual_router_ip_address"] = ipAddress;
if(type != 'hypervisor' && type != '' && type != 'empty') {
postObject["virtual-router"]["virtual_router_type"] = [type];
} else {
postObject["virtual-router"]["virtual_router_type"] = [];
}
if(mode === 'edit') {
postObject["virtual-router"]["uuid"] = gblSelRow.uuid;
}
doAjaxCall(url, methodType, JSON.stringify(postObject),
'successHandlerForVirtualRouters',
'failureHandlerForCreateVirtualRouters', null, null);
Any body can fix it, or give some advise about how to fix it
I prefer to change vnc_cfg.xsd's VirtualRouterType to an string array
type, but I can't find a way to rewrite the xsd.
