10.4. Déployer par l'API HTTP

Procédure 10.8. Déployer une application par DeployDmrToJson.java

1. Utiliser DeployDmrToJson.java pour créer une requête à JSON de déploiement de votre application.

   Exemple 10.2. DeployDmrToJson.java class

   import org.jboss.dmr.ModelNode;
   import java.net.URL;
   
   public class DeployDmrToJson
   {
     public static void main(String[] args) throws Exception
     {
       if(args.length < 1)
         throw new IllegalArgumentException("The first argument must be a URL");
   
       URL url = new URL(args[0]);
       String[] pathElements = url.getFile().split("/");
       String name = pathElements[pathElements.length-1];
   
       ModelNode deploy = getDeploy(url.toExternalForm(), name);
       ModelNode undeploy = getUndeploy(name);
   
       System.out.println("Deploy\n------------------------------\n");
       System.out.println("Formatted:\n" + deploy.toJSONString(false));
       System.out.println("Unformatted:\n" + deploy.toJSONString(true));
       System.out.println("\nUndeploy\n------------------------------\n");
       System.out.println("Formatted:\n" + undeploy.toJSONString(false));
       System.out.println("Unformatted:\n" + undeploy.toJSONString(true));
     }
   
     public static ModelNode getUndeploy(String name)
     {
       ModelNode undeployRequest = new ModelNode();
       undeployRequest.get("operation").set("undeploy");
       undeployRequest.get("address", "deployment").set(name);
   
       ModelNode removeRequest = new ModelNode();
       removeRequest.get("operation").set("remove");
       removeRequest.get("address", "deployment").set(name);
   
       ModelNode composite = new ModelNode();
       composite.get("operation").set("composite");
       composite.get("address").setEmptyList();
       final ModelNode steps = composite.get("steps");
       steps.add(undeployRequest);
       steps.add(removeRequest);
       return composite;
     }
   
     public static ModelNode getDeploy(String url, String name)
     {
       ModelNode deployRequest = new ModelNode();
       deployRequest.get("operation").set("deploy");
       deployRequest.get("address", "deployment").set(name);
   
       ModelNode addRequest = new ModelNode();
       addRequest.get("operation").set("add");
       addRequest.get("address", "deployment").set(name);
       addRequest.get("content").get(0).get("url").set(url);
   
       ModelNode composite = new ModelNode();
       composite.get("operation").set("composite");
       composite.get("address").setEmptyList();
       final ModelNode steps = composite.get("steps");
       steps.add(addRequest);
       steps.add(deployRequest);
       return composite;
     }
   }

2. Exécuter la classe par une commande basée sur les instructions suivantes :

   Exemple 10.3. Commande Execute

   java -cp .:$JBOSS_HOME/modules/org/jboss/dmr/main/jboss-dmr-1.1.1.Final-redhat-1.jar DeployDmrToJson \
   file:///Users/username/support/helloWorld.war/dist/helloWorld.war

3. Quand la classe est exécutée, les formats de commande suivants seront affichés. Utiliser la commande deploy ou la commande undeploy selon vos besoins.

   Exemple 10.4. Commande de déploiement et de suppression de déploiement

   Deploy
   ------------------------------
   
   Formatted:
   {
       "operation" : "composite",
       "address" : [],
       "steps" : [
           {
               "operation" : "add",
               "address" : {"deployment" : "helloWorld.war"},
               "content" : [{"url" : "file:/Users/username/support/helloWorld.war/dist/helloWorld.war"}]
           },
           {
               "operation" : "deploy",
               "address" : {"deployment" : "helloWorld.war"}
           }
       ]
   }
   Unformatted:
   {"operation" : "composite", "address" : [], "steps" : [{"operation" : "add", "address" : {"deployment" : "helloWorld.war"}, "content" : [{"url" : "file:/Users/username/support/helloWorld.war/dist/helloWorld.war"}]},{"operation" : "deploy", "address" : {"deployment" : "helloWorld.war"}}]}
   
   Undeploy
   ------------------------------
   
   Formatted:
   {
       "operation" : "composite",
       "address" : [],
       "steps" : [
           {
               "operation" : "undeploy",
               "address" : {"deployment" : "helloWorld.war"}
           },
           {
               "operation" : "remove",
               "address" : {"deployment" : "helloWorld.war"}
           }
       ]
   }
   Unformatted:
   {"operation" : "composite", "address" : [], "steps" : [{"operation" : "undeploy", "address" : {"deployment" : "helloWorld.war"}},{"operation" : "remove", "address" : {"deployment" : "helloWorld.war"}}]}
   

4. Utiliser la commande suivante pour déployer ou supprimer le déploiement d'une application. Remplacer json request par la requête décrite ci-dessus.

   Exemple 10.5. Commande Execute

   curl -f --digest -u "<user>:<pass>" -H Content-Type:\ application/json -d '<json request>' "http://localhost:9990/management"
