title: How to reload values in com.google.common.base.Supplier on demand
body: <p>I have a Supplier defined as below in one the Services. This supplier loads some values from database.</p>
  
  <pre><code>private final Supplier&lt;Map&lt;CustomClass1, CustomClass2&gt;&gt; sampleSupplier = Suppliers.memoizeWithExpiration(getSampleSupplier(), 1, TimeUnit.DAYS);
  </code></pre>
  
  <p>I want to reload values in this supplier on demand so that if database is updated within the Time Duration(1 Day), those values will be reloaded into the Supplier. Is there any way I can achieve this?</p>
