title: Creating a Java Object from JSON Object containing JSON Maps using GSON
body: <p>So, I've been doing GSON for a while, but I just now ran into the issue of using JSON Maps, which as I understand it are basically just Key Value pairs where he value is a JSON object. </p>
  
  <p>To give you an idea where I'm coming from, here's my JSON</p>
  
  <pre><code>{
     "configs":[
        {
           "com.hp.sdn.adm.alert.impl.AlertManager":{
              "trim.alert.age":{
                 "def_val":"14",
                 "desc":"Days an alert remains in storage (1 - 31)",
                 "val":"14"
              },
              "trim.enabled":{
                 "def_val":"true",
                 "desc":"Allow trim operation (true/false)",
                 "val":"true"
              },
              "trim.frequency":{
                 "def_val":"24",
                 "desc":"Frequency in hours of trim operations (8 - 168)",
                 "val":"24"
              }
           }
        },
        {
           "com.hp.sdn.adm.auditlog.impl.AuditLogManager":{
              "trim.auditlog.age":{
                 "def_val":"365",
                 "desc":"Days an audit log remains in storage (31 - 1870)",
                 "val":"365"
              },
              "trim.enabled":{
                 "def_val":"true",
                 "desc":"Allow trim operation (true/false)",
                 "val":"true"
              },
              "trim.frequency":{
                 "def_val":"24",
                 "desc":"Frequency in hours of trim operations (8 - 168)",
                 "val":"24"
              }
           }
        }
     ]
  }
  </code></pre>
  
  <p>All of those com.hp.sdn... things are dynamic, as in I won't know the key names until Runtime. I figured I can just use a HashMap for this and GSON would figure it out, but I'm not sure what I would name the field...</p>
  
  <hr>
  
  <p>Here are my classes that I have so far</p>
  
  <pre><code>package com.wicomb.sdn.models.configs;
  
  import java.util.HashMap;
  
  import com.wicomb.sdn.types.Model;
  
  public class ConfigResponse extends Model {
      private ConfigGroup[] configs;
  }
  </code></pre>
  
  <hr>
  
  <pre><code>package com.wicomb.sdn.models.configs;
  
  import com.wicomb.sdn.types.Model;
  
  public class ConfigGroup extends Model {
      private HashMap&lt;String,Config&gt; ????;
  }
  </code></pre>
  
  <p>TL;DR How should I write the Java Class to let Gson know how to handle a Json property that I don't know the name of.. And lots of them.</p>
