Configuring Connection Details

The name of the binder for Solace is solace.

Solace Connection Details

The Spring Cloud Stream Binder for Solace uses Spring Boot Auto-Configuration for the Solace Java API to configure its session. In the application.yml, this typically is configured as follows:

solace:
  java:
    host: tcp://localhost:55555
    msg-vpn: default
    client-username: default
    client-password: default    

For more information and options to configure the Solace session, see Spring Boot Auto-Configuration for the Solace Java API.

Preventing Message Loss when Publishing to Topic-to-Queue Mappings

If the Micro-Integration is publishing to a topic that is subscribed to by a queue, messages may be lost if they are rejected (for example, if queue ingress is shut down).

To prevent message loss, configure the reject-msg-to-sender-on-discard option with the including-when-shutdown flag.

Connecting to Multiple Systems

To connect to multiple systems of the same type, use the multiple binder syntax.    

For example:

spring: 
  cloud:
    stream: 
      binders:
        
        # 1st solace binder in this example 
     solace1:
          type: solace 
       environment: 
         solace: 
           java:
             host: tcp://localhost:55555
         
     # 2nd solace binder in this example 
     solace2:
          type: solace 
          environment: 
            solace: 
           java:
             host: tcp://other-host:55555
        
     # Required for internal use 
     undefined:
          type: undefined 
     bindings:
          input-0:
            destination: <input-destination> 
         binder: solace1                  
          output-0:
            destination: <output-destination>
            binder: solace1 # Reference 1st solace binder 
       input-1:
            destination: <input-destination> 
         binder: solace1        
           output-1:
            destination: <output-destination>
            binder: solace2 # Reference 2nd solace binder

The configuration above defines two binders of type solace, which are then referenced within the bindings.

Each binder above is configured independently under spring.cloud.stream.binders.<bindername>.environment..
