023-spring Boot Service Registration and discovery

I. Overview

Service invocation

1.1. Nginx Mode

　　

1.2. Registration Center

　　

Second, the registration center "zookeeper" 2.1, the installation of zookeeper3.4.112.2, service providers, need to start the service, the Service information (Ip,port) registered to the registration center.

In the mall-product of the previous section, POM

        <Dependency>            <groupId>Org.apache.curator</groupId>            <Artifactid>Curator-x-discovery-server</Artifactid>            <version>2.12.0</version>        </Dependency>

Add configuration

zookeeper.address=127.0.0.1:2181

Add Registration Class Serviceregister

@Component Public classServiceregisterImplementsApplicationrunner {@Value ("${zookeeper.address}")    PrivateString zkaddress; @Override Public voidRun (applicationarguments args)throwsException {curatorframework client= Curatorframeworkfactory.newclient (zkaddress,NewRetryonetime (1000));        Client.start ();        Client.blockuntilconnected (); Serviceinstance<Object> instance = Serviceinstance.builder (). Name ("Product"). Address ("127.0.0.1"). Port (8080). Build ();//Registered address and Port Servicediscovery<Object> discovery = Servicediscoverybuilder.builder (Object.class). Client (client). BasePath ("/soa"). build ();        Discovery.registerservice (instance);    Discovery.start (); }}

Pom

        <Dependency>                            <groupId>Org.apache.curator</groupId>                        <Artifactid>Curator-x-discovery</Artifactid>                   <version>2.12.0</version>        </Dependency>

When making a call, you need to get the service address from the registry and then call it based on the service address that was obtained.

Call

     Public Static voidMain (string[] args)throwsException {curatorframework client= Curatorframeworkfactory.newclient ("127.0.0.1:2181",NewRetryonetime (1000));        Client.start ();        Client.blockuntilconnected (); Servicediscovery<Object> discovery = Servicediscoverybuilder.builder (Object.class). Client (client). BasePath ("/soa"). build (); Collection<ServiceInstance<Object>> instances = discovery.queryforinstances ("Product"); Instances.foreach (item)-{System.out.println (item.getaddress ());            System.out.println (Item.getport ()); Resttemplate RT=Newresttemplate (); String String= Rt.getforobject ("/http" + item.getaddress () + ":" + item.getport () + "/SOA/PRODUCT/1", String.class);            System.out.println (string); Response<Product> Fromjson =NewGson (). Fromjson (String,NewTypetoken<response<product>>() {}.gettype ()); System.out.println (NewGson (). ToJson (Fromjson));    }); }

If you have more than one service, you can increase the load class
