This repository contains the core Java API and data model used to interact with REST services on a SiteWhere instance.

The Java client wraps the Spring RestTemplate mechanism and takes care of acquiring a JWT from the SiteWhere instance and storing it for use in the REST API calls. A new client with the default settings may be created as follows:

ISiteWhereClient client = SiteWhereClient.newBuilder().build().initialize();

The default settings are:

Note that the initialize() method must be called before using the client. This sets up the template and connects to the server to acquire a JWT.

To change the default connection settings use:

SiteWhereClient.newBuilder().withConnectionTo("https", "myhost", 8081).build().initialize();

To connect as a different user user:

SiteWhereClient.newBuilder().forUser("myuser", "mypassword").build().initialize();

Once the client has been initialized, methods on it may be invoked to interact with the data model on the remote SiteWhere instance. There are two types of calls, global calls and tenant-specific calls.

For global calls, no extra information is required in order to make the invocation. For instance, to get the instance version information, invoke:

Version version = client.getSiteWhereVersion();

The object model for all of the core SiteWhere data model is included with the client.

For calls that are tenant-specific, more information must be passed along with each method invocation. You must provide the tenant id and tenant authentication token which are passed as headers to the REST call (along with the JWT used for all calls). The format for tenant calls is:

DeviceType type = getClient().getDeviceTypeByToken(SiteWhereClient.defaultTenant(), "galaxytab3");

for the default tenant installed with the contruction example data, or for an arbitrary tenant

DeviceType type = getClient().getDeviceTypeByToken(SiteWhereClient.forTenant("token", "auth"), "galaxytab3");

using the unique token for the tenant and the tenant authentication token specific to that tenant.
