the id of the service from the <code class="literal">DiscoveryClient</code>.</p><p>The default filter is rewrite path filter with the regex <code class="literal">/serviceId/(?&lt;remaining&gt;.*)</code> and the replacement
<code class="literal">/${remaining}</code>. This just strips the service id from the path before the request is sent
downstream.</p><p>If you would like to customize the predicates and/or filters used by the <code class="literal">DiscoveryClient</code> routes you can do so
by setting <code class="literal">spring.cloud.gateway.discovery.locator.predicates[x]</code> and <code class="literal">spring.cloud.gateway.discovery.locator.filters[y]</code>.
When doing so you need to make sure to include the default predicate and filter above, if you want to retain
that functionality. Below is an example of what this looks like.</p><p><b>application.properties.&nbsp;</b>
</p><pre class="screen">spring.cloud.gateway.discovery.locator.predicates[0].name: Path
spring.cloud.gateway.discovery.locator.predicates[0].args[pattern]: "'/'+serviceId+'/**'"

spring.cloud.gateway.discovery.locator.predicates[1].args[pattern]: "'**.foo.com'"
spring.cloud.gateway.discovery.locator.filters[0].name: Hystrix
spring.cloud.gateway.discovery.locator.filters[0].args[name]: serviceId
spring.cloud.gateway.discovery.locator.filters[1].name: RewritePath
