## More information
```java
import io.dapr.client.DaprClient;
import io.dapr.client.DaprClientBuilder;
try (DaprClient client = (new DaprClientBuilder()).build()) {
// sending a class with message; BINDING_OPERATION="create"
client.invokeBinding(BINDING_NAME, BINDING_OPERATION, myClass).block();
// sending a plain string
client.invokeBinding(BINDING_NAME, BINDING_OPERATION, message).block();
}
```
- For a full guide on output bindings visit [How-To: Output bindings]({{< ref howto-bindings.md >}}).
- Visit [Java SDK examples](https://github.com/dapr/java-sdk/tree/master/examples/src/main/java/io/dapr/examples/bindings/http) for code samples and instructions to try out output bindings.
### Interact with input bindings
```java
import org.springframework.web.bind.annotation.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
@RestController
@RequestMapping("/")
public class myClass {
private static final Logger log = LoggerFactory.getLogger(myClass);
@PostMapping(path = "/checkout")
public Mono<String> getCheckout(@RequestBody(required = false) byte[] body) {
return Mono.fromRunnable(() ->
log.info("Received Message: " + new String(body)));
}
}
```

### Retrieve secrets
```java
import com.fasterxml.jackson.databind.ObjectMapper;
import io.dapr.client.DaprClient;
import io.dapr.client.DaprClientBuilder;
import java.util.Map;
try (DaprClient client = (new DaprClientBuilder()).build()) {
Map<String, String> secret = client.getSecret(SECRET_STORE_NAME, secretKey).block();
System.out.println(JSON_SERIALIZER.writeValueAsString(secret));
}
```

### Actors
An actor is an isolated, independent unit of compute and state with single-threaded execution. Dapr provides an actor implementation based on the [Virtual Actor pattern](https://www.microsoft.com/en-us/research/project/orleans-virtual-actors/), which provides a single-threaded programming model and where actors are garbage collected when not in use. With Dapr's implementaiton, you write your Dapr actors according to the Actor model, and Dapr leverages the scalability and reliability that the underlying platform provides.
```java
import io.dapr.actors.ActorMethod;
import io.dapr.actors.ActorType;
import reactor.core.publisher.Mono;
@ActorType(name = "DemoActor")
public interface DemoActor {
void registerReminder();
@ActorMethod(name = "echo_message")
String say(String something);
void clock(String message);
@ActorMethod(returns = Integer.class)
Mono<Integer> incrementAndGet(int delta);
}
```

### Get & Subscribe to application configurations
> Note this is a preview API and thus will only be accessible via the DaprPreviewClient interface and not the normal DaprClient interface
```java
import io.dapr.client.DaprClient;
import io.dapr.client.DaprClientBuilder;
import io.dapr.client.domain.ConfigurationItem;
import io.dapr.client.domain.GetConfigurationRequest;
import io.dapr.client.domain.SubscribeConfigurationRequest;
import reactor.core.publisher.Flux;
import reactor.core.publisher.Mono;
try (DaprClient client = (new DaprClientBuilder()).build()) {
// Get configuration for a single key
Mono<ConfigurationItem> item = client.getConfiguration(CONFIG_STORE_NAME, CONFIG_KEY).block();
// Get configurations for multiple keys
Mono<Map<String, ConfigurationItem>> items =
client.getConfiguration(CONFIG_STORE_NAME, CONFIG_KEY_1, CONFIG_KEY_2);
// Subscribe to configuration changes
Flux<SubscribeConfigurationResponse> outFlux = client.subscribeConfiguration(CONFIG_STORE_NAME, CONFIG_KEY_1, CONFIG_KEY_2);
outFlux.subscribe(configItems -> configItems.forEach(...));
// Unsubscribe from configuration changes
Mono<UnsubscribeConfigurationResponse> unsubscribe = client.unsubscribeConfiguration(SUBSCRIPTION_ID, CONFIG_STORE_NAME)
}
```

### Query saved state

.setSort(Arrays.asList(new Sorting("id", Sorting.Order.DESC)));
QueryStateRequest request = new QueryStateRequest(STATE_STORE_NAME)
.setQuery(query);
// Use preview client to call query state API
QueryStateResponse<MyData> result = previewClient.queryState(request, MyData.class).block();
// View Query state response
System.out.println("Found " + result.getResults().size() + " items.");
for (QueryStateItem<Listing> item : result.getResults()) {
System.out.println("Key: " + item.getKey());
