How to Configure Spring Boot with Memcached

I am new to Memcached. I need to configure my spring boot application with Memcached.

I researched a lot on the topic but I could not find a documentation for the same.
By default Spring boot uses Concurrent HashMap for caching but how do I configure Memcached.

I got this GitHub URL but I am not sure if this is the correct way and if so how do I use the same.

https://www.javacodegeeks.com/2013/06/simple-spring-memcached-spring-caching-abstraction-and-memcached.html

Update

I have used this in my project now https://github.com/bmatthews68/memcached-spring-boot-starter.

Like this

@Override @Cacheable(value = "defaultCache")
    public String customMethof() throws InterruptedException {
        return "Testing";
    }

but when i do a telnet of get defaultCache i get nothing Please help

    The first GitHub project you have shown is a good solution. It is also a fork a spymemcached which is one of the prominent client libraries of Memcached.

    Please refer the below official documentation.
    http://cloud.spring.io/spring-cloud-aws/spring-cloud-aws.html#_caching

    You can also check the below one and traverse to Getting Started page.

    Add this to your Gradle Dependencies

    compile group: 'net.spy', name: 'spymemcached', version: '2.12.3'
compile('com.btmatthews.springboot:memcached-spring-boot-starter:1.0.0')

    On top of your main Spring boot application where you @SpringBootApplicationthis annotation put this

    @EnableMemcached

    Then in your Component use the following

    @Autowired
private MemcachedClient memcachedClient;

memcachedClient.get("...")

    I’m one of the authors of the https://github.com/sixhours-team/memcached-spring-boot.
    The library will auto-configure Memcached within a Spring Boot application. You can enable it just as you would with Spring Cache i.e. it is sufficient to add the @EnableCaching annotation in your configuration class e.g.

    @Configuration
@EnableCaching
public class CacheConfiguration {
}

    The configuration in the application.yml can be as simple as: 

    memcached.cache:
   servers: example1.com:11211
   mode: static
   expiration: 86400

    At the moment, the library has not been released yet (the first release should be in about a week). You can find more info here or check the demo Spring Boot app here.

    One more thing, in order to support cache eviction, the library is prefixed with memcached:spring-boot:defaultCache:[radnom_number], so in your case the key would be something like e.g.

    memcached:spring-boot:books:defaultCache:283:SimpleKey[]

    where 283 is the random number assigned to the cache key (needed for the proper cache eviction).
