    <p>I think, solution number 4 is OK. It is simple to understand and clear.</p> <p>I propose similar solution in which we can use <a href="http://www.cowtowncoder.com/blog/archives/2011/07/entry_458.html" rel="noreferrer">@JsonAnySetter</a> annotation. Please, see below example:</p> <pre><code>import com.fasterxml.jackson.annotation.JsonAnySetter; import com.fasterxml.jackson.databind.ObjectMapper; public class JacksonProgram { public static void main(String[] args) throws Exception { C1 c1 = new C1(); c1.setProp1("a"); c1.setProp3("c"); User user = new User(); user.setName("Tom"); user.setSurname("Irg"); ObjectMapper mapper = new ObjectMapper(); System.out.println(mapper.convertValue(c1, UriFormat.class)); System.out.println(mapper.convertValue(user, UriFormat.class)); } } class UriFormat { private StringBuilder builder = new StringBuilder(); @JsonAnySetter public void addToUri(String name, Object property) { if (builder.length() &gt; 0) { builder.append("&amp;"); } builder.append(name).append("=").append(property); } @Override public String toString() { return builder.toString(); } } </code></pre> <p>Above program prints:</p> <pre><code>prop1=a&amp;prop2=null&amp;prop3=c name=Tom&amp;surname=Irg </code></pre> <p>And your getRequest method could look like this:</p> <pre><code>public String getRequest(String url, Object obj) { String serializedUri = mapper.convertValue(obj, UriFormat.class).toString(); String response = restTemplate.getForObject(url + "?" + serializedUri, String.class); return response; } </code></pre>

    1. CO**VERY** interesting and cool. I will definitely go with this, unless I hear other suggestions. I agree #4 was pretty good - I'm guessing it does #2 behind the scenes anyways, so I might as well keep it (except I really like this solution, so I will use it :) ).

    2. COI glad to hear it. Feel free to use it. Jackson is reliable and fast so I think, you should reuse as much source code as you can from Jackson library. You should also remember about URL encoding and other stuff like that.

    3. COCool, I appreciate it. This answer is exactly what I was looking for - a feature of Jackson that I didn't know about (because I don't know nearly enough about, or utilize, the library). I don't know if it's applicable, but it seemed like using `@JsonView` might be another alternative. Do you have any insight on how to use it in this scenario or why (not) to use it in comparison to your solution?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
