Question

I am using dropwizard which uses jersey & jackson for json. My issue is when I return a list it does not specify a root.

I have a POJO class:

public class Company { 
public String id; 
public String name; 
public String address; 
}

and my resource is set up thus:

@GET
@Path("/companies/all")
public List<Company> getAllCompanies(){
    ...
    return companies;
}

And I get the following response:

[{
"id": "01",
"name": "Yammer Corp",
"address": "1 Finite Loop"
},
{
"id": "02",
"name": "DropWizards Inc",
"address": "4 Magic Square, Olympus"
}]

While what I want is something like below:

{"Companies" : 
[{
"id": "01",
"name": "Yammer Corp",
"address": "1 Finite Loop"
},
{
"id": "02",
"name": "DropWizards Inc",
"address": "4 Magic Square, Olympus"
}
]}

Any ideas? Thanks in advance.

You need to create one more POJO wrapping the List<Company>

public class ApiResponse
{
   private List<Company> Companies;
   //Getter and Setter
   //Public Constructor
}

The Change required in your GET Method is:

@GET
@Path("/companies/all")
public ApiResponse getAllCompanies(){
    //Set your ApiResponse Object with the companies List.
    ApiResponse apiResponse = new ApiResponse(companies);
    return apiResponse;
}
