title: Missing CrudRepository#findOne method
body: <p>I am using Spring 5 in my project. Until today there was available method <a href="https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/repository/CrudRepository.html#findOne-ID-" rel="noreferrer"><code>CrudRepository#findOne</code></a>.</p>
  
  <p>But after downloading latest snapshot it suddenly disappeared! Is there any reference that the method is not available now?</p>
  
  <p>My dependency list:</p>
  
  <pre><code>apply plugin: 'java'
  apply plugin: 'org.springframework.boot'
  apply plugin: 'io.spring.dependency-management'
  
  
  repositories {
      mavenCentral()
      maven { url "https://repo.spring.io/snapshot" }
      maven { url "https://repo.spring.io/milestone" }
  }    
  
  dependencies {
      compile 'org.springframework.boot:spring-boot-starter-data-jpa'
  
      runtime 'com.h2database:h2:1.4.194'
  }
  </code></pre>
  
  <p><strong>UPDATE:</strong></p>
  
  <p>Seems that this method has been replaced with <a href="https://docs.spring.io/spring-data/commons/docs/current/api/org/springframework/data/repository/CrudRepository.html#findById-ID-" rel="noreferrer"><code>CrudRepository#findById</code></a></p>
