endpointRemapper

public ClientOptionsBuilder endpointRemapper(Function<? super Endpoint,? extends EndpointGroup> endpointRemapper)

Description copied from class: AbstractClientOptionsBuilder

Sets a Function that remaps an Endpoint into an EndpointGroup. This ClientOption is useful when you need to override a single target host into a group of hosts to enable client-side load-balancing, e.g.

 MyService.Iface client =
     Clients.newClient("tbinary+http://example.com/api",
                       MyService.Iface.class);

 EndpointGroup myGroup = EndpointGroup.of(Endpoint.of("node-1.example.com")),
                                          Endpoint.of("node-2.example.com")));

 MyService.Iface derivedClient =
     Clients.newDerivedClient(client, options -> {
         return options.toBuilder()
                       .endpointRemapper(endpoint -> {
                           if (endpoint.host().equals("example.com")) {
                               return myGroup;
                           } else {
                               return endpoint;
                           }
                       })
                       .build();
     });

 // This request goes to 'node-1.example.com' or 'node-2.example.com'.
 derivedClient.call();
 

Note that the remapping does not occur recursively but only once.

contextCustomizer

public ClientOptionsBuilder contextCustomizer(Consumer<? super ClientRequestContext> contextCustomizer)

Description copied from class: AbstractClientOptionsBuilder

Adds the specified ClientRequestContext customizer function so that it customizes the context in the thread that initiated the client call. The given customizer function is evaluated before the customizer function specified by Clients.withContextCustomizer(Consumer).

 static final ThreadLocal<String> USER_ID = new ThreadLocal<>();
 static final AttributeKey<String> USER_ID_ATTR = AttributeKey.valueOf("USER_ID");
 ...
 MyClientStub client =
     Clients.builder(...)
            .contextCustomizer(ctx -> {
                // This customizer will be invoked from the thread that initiates a client call.
                ctx.setAttr(USER_ID_ATTR, USER_ID.get());
            })
            .build(MyClientStub.class);

 // Good:
 // The context data is set by the thread that initiates the client call.
 USER_ID.set("user1");
 try {
     client.executeSomething1(..);
     ...
     client.executeSomethingN(..);
 } finally {
     // Should clean up the thread local storage.
     USER_ID.remove();
 }

 // Bad:
 USER_ID.set("user1");
 executor.execute(() -> {
     // The variable in USER_ID won't be propagated to the context.
     // The variable is not valid at the moment client.executeSomething1() is called.
      client.executeSomething1(..);
 });
 

Note that certain properties of ClientRequestContext, such as:

• ClientRequestContext.endpoint()
• RequestContext.localAddress()
• RequestContext.remoteAddress()

may be null while the customizer function runs, because the target host of the Request is not determined yet.
