Registering with multiple registries

A service can be registered with multiple registries. Use one of the following methods:

Using XML

1. Configure the registry source information in the application.properties file.

   The configuration format is com.alipay.sofa.rpc.registries.<custom_alias>=protocol://address. Supported protocols include dsr, sofa, zookeeper, consul, gateway, mesh, multicast, local, and nacos.

   The following code shows an example:

   com.alipay.sofa.rpc.registries.registryName1=dsr://10.0.0.1:9600
   com.alipay.sofa.rpc.registries.registryName2=dsr://10.0.0.2:9600

2. Configure the service that requires multiple registries.

   <sofa:service interface="com.alipay.sofa.facade.SampleService" ref="sampleService">
           <sofa:binding.bolt>
               <sofa:global-attrs registry="registryName1,registryName2"/>
           </sofa:binding.bolt>
   
       </sofa:service>

Using the API

1. Create a registry.

   The following code shows an example of how to create a registry named consul:

   RegistryConfig registryA = new RegistryConfig().setProtocol("consul").setAddress("localhost:8500");

2. Build multiple RegistryConfig objects and add them to the ProviderConfig object.

   Example:

   List<RegistryConfig> registryConfigs =new ArrayList<RegistryConfig>();
   registryConfigs.add(registryA);
   registryConfigs.add(registryB);
   providerConfig.setRegistry(registryConfigs);

3. Call the set methods on a MethodConfig object to configure method-specific parameters.

   The following is an example:

   MethodConfig methodConfigA =new MethodConfig();
   MethodConfig methodConfigB =new MethodConfig();
   List<MethodConfig> methodConfigs =new ArrayList<MethodConfig>();
   methodConfigs.add(methodConfigA);
   methodConfigs.add(methodConfigB);
   providerConfig.setMethods(methodConfigs);    // Server-side setting
   consumerConfig.setMethods(methodConfigs);  // Client-side setting
