So it could be your first pick when you&#8217;re already creating
software for the JVM. This project has a lot of really interesting features but especially quite a few of them definitely make
Spring Cloud Contract Verifier stand out on the "market" of Consumer Driven Contract (CDC) tooling.

Only if they can be vastly used, will they serve their purpose.
What typically makes that difficult are the hard-coded values of request / response elements. For example dates or ids.
Imagine the following JSON request</p><pre class="programlisting"><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">{</span>

database) by changing the clock in the system or providing stub implementations of data providers. The same is related
to the field called <code class="literal">id</code>. Will you create a stubbed implementation of UUID generator? Makes little sense&#8230;&#8203;</p><p>So as a consumer you would like to send a request that matches any form of a time or any UUID. That way your system
will work as usual - will generate data and you won&#8217;t have to stub anything out. Let&#8217;s assume that in case of the aforementioned
JSON the most important part is the <code class="literal">body</code> field. You can focus on that and provide matching for other fields. In other words
you would like the stub to work like this:</p><pre class="programlisting"><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">{</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"time"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"SOMETHING THAT MATCHES TIME"</span><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">,</span>

<span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">}</span></pre><p>As far as the response goes as a consumer you need a concrete value that you can operate on.

much different. We&#8217;re parsing the provided contract and in the test we want to send a real request to your endpoints.
So for the case of a producer for the request we can&#8217;t have any sort of matching. We need concrete values that the
producer&#8217;s backend can work on. Such a JSON would be a valid one:</p><pre class="programlisting"><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">{</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"time"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"2016-10-10 20:10:15"</span><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">,</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"id"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"9febab1c-6f36-4a0b-88d6-3b6a6d81cd4a"</span><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">,</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"body"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"foo"</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">}</span></pre><p>On the other hand from the point of view of the validity of the contract the response doesn&#8217;t necessarily have to
contain concrete values of <code class="literal">time</code> or <code class="literal">id</code>. Let&#8217;s say that you generate those on the producer side - again, you&#8217;d
have to do a lot of stubbing to ensure that you always return the same values. That&#8217;s why from the producer&#8217;s side
what you might want is the following response:</p><pre class="programlisting"><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">{</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"time"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"SOMETHING THAT MATCHES TIME"</span><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">,</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"id"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"SOMETHING THAT MATCHES UUID"</span><span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">,</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"body"</span> : <span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"bar"</span>
<span xmlns:d="http://docbook.org/ns/docbook" class="hl-keyword">}</span></pre><p>How can you then provide one time a matcher for the consumer and a concrete value for the producer and vice versa?
In Spring Cloud Contract we&#8217;re allowing you to provide a <span class="strong"><strong>dynamic value</strong></span>. That means that it can differ for both
sides of the communication. You can pass the values:</p><p>Either via the <code class="literal">value</code> method</p><pre class="programlisting">value(consumer(...), producer(...))
value(stub(...), test(...))
value(client(...), server(...))</pre><p>or using the <code class="literal">$()</code> method</p><pre class="programlisting">$(consumer(...), producer(...))
$(stub(...), test(...))
$(client(...), server(...))</pre><p>You can read more about this in the <a class="link" href="https://cloud.spring.io/spring-cloud-contract/spring-cloud-contract.html#_contract_dsl" target="_top">Contract DSL section</a>.</p><p>Calling <code class="literal">value()</code> or <code class="literal">$()</code> tells Spring Cloud Contract that you will be passing a dynamic value.
Inside the <code class="literal">consumer()</code> method you pass the value that should be used on the consumer side (in the generated stub).
Inside the <code class="literal">producer()</code> method you pass the value that should be used on the producer side (in the generated test).</p><div class="tip" style="margin-left: 0.5in; margin-right: 0.5in;"><table border="0" summary="Tip"><tr><td rowspan="2" align="center" valign="top" width="25"><img alt="[Tip]" src="images/tip.png"></td><th align="left">Tip</th></tr><tr><td align="left" valign="top"><p>If on one side you have passed the regular expression and you haven&#8217;t passed the other, then the
other side will get auto-generated.</p></td></tr></table></div><p>Most often you will use that method together with the <code class="literal">regex</code> helper method. E.g. <code class="literal">consumer(regex('[0-9]{10}'))</code>.</p><p>To sum it up the contract for the aforementioned scenario would look more or less like this (the regular expression
for time and UUID are simplified and most likely invalid but we want to keep things very simple in this example):</p><pre class="programlisting">org.springframework.cloud.contract.spec.Contract.make {

the jar each time you go through the pipeline and that jar can go to production at any time. For example your jar version
looks like this (it got built on the 20.10.2016 at 20:15:21) :</p><pre class="programlisting"><span class="hl-number">1.0</span>.<span class="hl-number">0.20161020</span>-<span class="hl-number">201521</span>-RELEASE</pre><p>In that case your generated stub jar will look like this.</p><pre class="programlisting"><span class="hl-number">1.0</span>.<span class="hl-number">0.20161020</span>-<span class="hl-number">201521</span>-RELEASE-stubs.jar</pre><p>In this case you should inside your <code class="literal">application.yml</code> or <code class="literal">@AutoConfigureStubRunner</code> when referencing stubs provide the
latest version of the stubs. You can do that by passing the <code class="literal">+</code> sign. Example</p><pre class="programlisting">@AutoConfigureStubRunner(ids = {<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"com.example:http-server-dsl:+:stubs:8080"</span>})</pre><p>If the versioning however is fixed (e.g. <code class="literal">1.0.4.RELEASE</code> or <code class="literal">2.1.1</code>) then you have to set the concrete value of the jar
version. Example for 2.1.1.</p><pre class="programlisting">@AutoConfigureStubRunner(ids = {<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"com.example:http-server-dsl:2.1.1:stubs:8080"</span>})</pre></div><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="_dev_or_prod_stubs" href="#_dev_or_prod_stubs"></a>82.3.3&nbsp;Dev or prod stubs</h3></div></div></div><p>You can manipulate the classifier to run the tests against current development version of the stubs of other services
or the ones that were deployed to production. If you alter your build to deploy the stubs with the <code class="literal">prod-stubs</code> classifier
once you reach production deployment then you can run tests in one case with dev stubs and one with prod stubs.</p><p>Example of tests using development version of stubs</p><pre class="programlisting">@AutoConfigureStubRunner(ids = {<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"com.example:http-server-dsl:+:stubs:8080"</span>})</pre><p>Example of tests using production version of stubs</p><pre class="programlisting">@AutoConfigureStubRunner(ids = {<span xmlns:d="http://docbook.org/ns/docbook" class="hl-string">"com.example:http-server-dsl:+:prod-stubs:8080"</span>})</pre><p>You can pass those values also via properties from your deployment pipeline.</p></div></div><div class="section"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="_common_repo_with_contracts" href="#_common_repo_with_contracts"></a>82.4&nbsp;Common repo with contracts</h2></div></div></div><p>Another way of storing contracts other than having them with the producer is keeping them in a common place.
It can be related to security issues where the consumers can&#8217;t clone the producer&#8217;s code. Also if you keep
contracts in a single place then you, as a producer, will know how many consumers you have and which
consumer will you break with your local changes.</p><div class="section"><div class="titlepage"><div><div><h3 class="title"><a name="_repo_structure" href="#_repo_structure"></a>82.4.1&nbsp;Repo structure</h3></div></div></div><p>Let&#8217;s assume that we have a producer with coordinates <code class="literal">com.example:server</code> and 3 consumers: <code class="literal">client1</code>,
