# Azure Web PubSub SDK for Java


Build real-time web applications using the Azure Web PubSub SDK for Java.


Installation


xml 
<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-messaging-webpubsub</artifactId>
    <version>1.5.0</version>
</dependency>

Client Creation


With Connection String


java 
import com.azure.messaging.webpubsub.WebPubSubServiceClient;
import com.azure.messaging.webpubsub.WebPubSubServiceClientBuilder;

WebPubSubServiceClient client = new WebPubSubServiceClientBuilder()
    .connectionString("<connection-string>")
    .hub("chat")
    .buildClient();

With Access Key


java 
import com.azure.core.credential.AzureKeyCredential;

WebPubSubServiceClient client = new WebPubSubServiceClientBuilder()
    .credential(new AzureKeyCredential("<access-key>"))
    .endpoint("<endpoint>")
    .hub("chat")
    .buildClient();

With DefaultAzureCredential


java 
import com.azure.identity.DefaultAzureCredentialBuilder;

WebPubSubServiceClient client = new WebPubSubServiceClientBuilder()
    .credential(new DefaultAzureCredentialBuilder().build())
    .endpoint("<endpoint>")
    .hub("chat")
    .buildClient();

Async Client


java 
import com.azure.messaging.webpubsub.WebPubSubServiceAsyncClient;

WebPubSubServiceAsyncClient asyncClient = new WebPubSubServiceClientBuilder()
    .connectionString("<connection-string>")
    .hub("chat")
    .buildAsyncClient();

Key Concepts


- **Hub**: Logical isolation unit for connections

- **Group**: Subset of connections within a hub

- **Connection**: Individual WebSocket client connection

- **User**: Entity that can have multiple connections


Core Patterns


Send to All Connections


java 
import com.azure.messaging.webpubsub.models.WebPubSubContentType;

// Send text message
client.sendToAll("Hello everyone!", WebPubSubContentType.TEXT_PLAIN);

// Send JSON
String jsonMessage = "{\"type\": \"notification\", \"message\": \"New update!\"}";
client.sendToAll(jsonMessage, WebPubSubContentType.APPLICATION_JSON);

Send to All with Filter


java 
import com.azure.core.http.rest.RequestOptions;
import com.azure.core.util.BinaryData;

BinaryData message = BinaryData.fromString("Hello filtered users!");

// Filter by userId
client.sendToAllWithResponse(
    message,
    WebPubSubContentType.TEXT_PLAIN,
    message.getLength(),
    new RequestOptions().addQueryParam("filter", "userId ne 'user1'"));

// Filter by groups
client.sendToAllWithResponse(
    message,
    WebPubSubContentType.TEXT_PLAIN,
    message.getLength(),
    new RequestOptions().addQueryParam("filter", "'GroupA' in groups and not('GroupB' in groups)"));

Send to Group


java 
// Send to all connections in a group
client.sendToGroup("java-developers", "Hello Java devs!", WebPubSubContentType.TEXT_PLAIN);

// Send JSON to group
String json = "{\"event\": \"update\", \"data\": {\"version\": \"2.0\"}}";
client.sendToGroup("subscribers", json, WebPubSubContentType.APPLICATION_JSON);

Send to Specific Connection


java 
// Send to a specific connection by ID
client.sendToConnection("connectionId123", "Private message", WebPubSubContentType.TEXT_PLAIN);

Send to User


java 
// Send to all connections for a specific user
client.sendToUser("andy", "Hello Andy!", WebPubSubContentType.TEXT_PLAIN);

Manage Groups


java 
// Add connection to group
client.addConnectionToGroup("premium-users", "connectionId123");

// Remove connection from group
client.removeConnectionFromGroup("premium-users", "connectionId123");

// Add user to group (all their connections)
client.addUserToGroup("admin-group", "userId456");

// Remove user from group
client.removeUserFromGroup("admin-group", "userId456");

// Check if user is in group
boolean exists = client.userExistsInGroup("admin-group", "userId456");

Manage Connections


java 
// Check if connection exists
boolean connected = client.connectionExists("connectionId123
