As of Spring Boot 2.1.2 the following configuration worked to resolve the issue. (Note, these are snippets of the overall config.)

Dependencies:

  org.springframework.boot
  spring-boot-starter-cache


  org.hibernate
  hibernate-core
  5.2.8.Final


  org.hibernate
  hibernate-ehcache
  5.2.8.Final

application.yml config:

spring:
  jpa:
    open-in-view: false
    hibernate:
      ddl-auto: none
    show-sql: true
    properties:
      dialect: org.hibernate.dialect.MySQLDialect
      net:
        sf:
          ehcache:
            configurationResourceName: ehcache.xml
      hibernate:
        cache:
          use_second_level_cache: true
          region:
            factory_class: org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

ehcache.xml configuration:

The application I am working on slows down drastically without a working cache. So, to validate I simply ran the application and hit one of the read intense endpoints.
