Looking for a dropwizard example

Question

Looking for a dropwizard example I found:

https://github.com/codahale/dropwizard/tree/master/dropwizard-example

But I am interested in a more complete example with at least:

1. a 1:n relationship like customer - account
2. a html gui represenation at least with forms
3. full crud support for xml

2 out of three would be a start and would earn "accepted" by me.

Answer 1

Take a look at some of my Dropwzard projects

In particular the MultiBit Merchant projects (Admin, Store and Platform) will provide you with a wealth of demonstration code that shows how to get stuff done in Dropwizard. There is also an example of OpenID with Dropwizard that should provide a good launch point for a new application.

They are all FOSS under the MIT license.

Answer 2

Wolfgang,

here is an example Dropwizard application where Authentication, Configuration and database access using Hibernate are used.

The application is discussed in several tutorials:

• First Steps
• Authentication, Configuration and HTTPS
• Connecting to a Database using Hibernate
• Connecting to external REST Web-services using Jersey Client

And here is another example, where one can store bookmarks for authenticated users and access data via REST API.

Good luck.

Answer 3

That looks like a nice example as well: https://github.com/spinscale/dropwizard-blog-sample

Answer 4

I wrote an example in my Dropwizard XML Bundle project:

https://github.com/yunspace/dropwizard-xml/tree/master/dropwizard-xml-example

It's probably the closest to what you are looking for. It has:

• 1:N relationship between Pirates and Ships, stored in a H2 db.
• Full CRUD support for XML using custom JacksonMessageBodyProvider with validation.

Adding HTML gui via Freemarker or Mustache templates should be pretty trivial and is covered in the standard docs.

Answer 5

A good example who want dropwizard with authentication.

Answer 6

You can try this project from Github.

Answer 7

follow below step.

1. Add dependencies in pom file

   <dependencies>
   <dependency>
       <groupId>com.yammer.dropwizard</groupId>
       <artifactId>dropwizard-core</artifactId>
       <version>0.6.2</version>
   </dependency> 
   

2. Create configuration class

   import com.yammer.dropwizard.config.Configuration;
   public class BlogConfiguration extends Configuration{
   
    }
   

3. Create Service class

      import com.yammer.dropwizard.Service;
      import com.yammer.dropwizard.config.Bootstrap;
      import com.yammer.dropwizard.config.Environment;
   
      public class BlogService extends Service<BlogConfiguration> {
   
      public static void main(String[] args) throws Exception {
      new BlogService().run(new String[] { "server",
      "C:\\LocalEnv\\Workspace\\dropwizarddemo\\configuration.yml" });
       }
   
       @Override
      public void initialize(Bootstrap<BlogConfiguration> bootstrap) {
      bootstrap.setName("blog");
      }
   
      @Override
       public void run(BlogConfiguration configuration, 
       Environment    environment) throws Exception {
       environment.addResource(new IndexResource());
       }
   
     }
   

Note: put below configuration.yml file in current directory

       # HTTP-specific options.
       http:

       # The port on which the HTTP server listens for service requests.
       port: 8079

       # The port on which the HTTP server listens for administrative
       # requests.
       adminPort: 8179

      # Maximum number of threads.
      maxThreads: 100

      # Minimum number of thread to keep alive.
      minThreads: 10

4. Write Index resources.

     import java.util.ArrayList;
     import java.util.Arrays;
     import java.util.List;
     import javax.ws.rs.GET;
     import javax.ws.rs.Path;
     import javax.ws.rs.Produces;
     import javax.ws.rs.core.MediaType;


    import com.yammer.metrics.annotation.Timed;

    @Path("/")
    public class IndexResource {

   @GET
   @Produces(value = MediaType.APPLICATION_JSON)
   @Timed
   public List<Blog> index() {
    return Arrays.asList(new Blog("for Java Developers",
   "http://stackoverflow.com/questions/13345693/looking-for-a-dropwizard-
    example”));
   }


   @Path("/service")


   @GET
   @Produces(value = MediaType.APPLICATION_JSON)
   @Timed
   public List<Users> users() {
    List<Users> list = new ArrayList<Users>();
    list.add(new Users(25,"Sambhu","SA"));
    list.add(new Users(35,"Amit","VP"));
    list.add(new Users(45,"Sanket","AVP"));


    return list;
    }


  }

5. Write POJO for Blog and Users like

    public class Users {
   
   
    Integer id;
    String name;
    String designation;
   
    public Users(Integer id, String name, String desination){
   this.id=id;
   this.name=name;
   this.designation=desination;
   }
   
   public Integer getId() {
   return id;
   }
   public void setId(Integer id) {
   this.id = id;
   }
   public String getName() {
   return name;
   }
   public void setName(String name) {
   this.name = name;
   }
   public String getDesignation() {
   return designation;
   }
   public void setDesignation(String designation) {
   this.designation = designation;
   }
   @Override
   public String toString() {
   return "Users [id=" + id + ", name=" + name + ", designation="
           + designation + "]";
   }
   

6. Run BlogService which will start the Jetty server and hit the localhost with port such as http://localhost:8079/
