Body
I'm constructing a restful service which needs to accept any number of parameters instead of the one from the sample below. Assuming the following service routine <pre><code>@RequestMapping("/start/id/{id}", RequestMethod.GET) public void startService(@PathVariable String id) {...} </code></pre> there's a client implementation based on <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/web/client/RestTemplate.html" rel="nofollow noreferrer"><code>RestTemplate</code></a> <pre><code>restTemplate.getForObject("/start/id/{id}", null, id); </code></pre> Question: But given that it might be thousands of <code>ids</code>, what restful approaches do I have to sending all parameters in one request using <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/web/client/RestTemplate.html" rel="nofollow noreferrer"><code>RestTemplate</code></a>? I've seen the suggestions <ul> <li>Add request body to GET request - Doesn't seem possible with <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/web/client/RestTemplate.html" rel="nofollow noreferrer"><code>RestTemplate</code></a>?</li> <li>Use a separator in id, (e.g., <code>id1|id2|....|idn</code>) - Seems like a hack</li> <li>PUT the parameters first, then issue a GET to reference the ids - Double requests, seems non-intuitive</li> <li>Adding multiple URL parameters (<code>?id=foo&id=bar&.....&id=foobar</code>)</li> </ul> <hr> I know similar questions (<a href="https://stackoverflow.com/questions/3841708/calling-a-restful-service-with-many-parameters">calling-a-restful-service-with-many-parameters</a>, <a href="https://stackoverflow.com/questions/1619152/how-to-create-rest-urls-without-verbs">how-to-create-rest-urls-without-verbs</a>, <a href="https://stackoverflow.com/questions/5377732/can-you-build-a-truly-restful-service-that-takes-many-parameters">can-you-build-a-truly-restful-service-that-takes-many-parameters</a>) has been asked before but I found it hard to spot a satisfactory answer, or at least an answer based on <a href="http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/web/client/RestTemplate.html" rel="nofollow noreferrer"><code>RestTemplate</code></a>.

Guidance

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.
