10.4. Déployer par l'API HTTP

Procédure 10.7. Déployer une application par DeployDmrToJson.java

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

   Exemple 10.1. 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("\nUneploy\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 10.2. 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 10.3. 

   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"}}]}
   
   Uneploy
   ------------------------------
   
   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 10.4. Commande Execute

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