I am using Spring boot 1.5.2.RELEASE, Spring 4.3.7, ehcache 3.3.1 in my application,

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns='http://www.ehcache.org/v3' xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

application.properties

spring.cache.jcache.config=classpath:ehcache.xml
spring.cache.cache-names=mayCache1,mayCache2,mayCache3
spring.cache.caffeine.spec=maximumSize=1000,expireAfterAccess=600s

pom.xml dependencies:

   	<dependency>
   		<groupId>javax.cache</groupId>
   		<artifactId>cache-api</artifactId>
                       <version>1.0.0</version>
   	</dependency>

   	<!-- Added for cache ehcache  -->
   	<dependency>
   		<groupId>org.ehcache</groupId>
   		<artifactId>ehcache</artifactId>
   		<version>3.3.1</version>
   	</dependency>

When I try to access cache manager in CacheConfiguration class it's throwing error like below:

Unsatisfied dependency expressed through field 'cacheManager'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'org.springframework.cache.CacheManager' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

While debugging I observed that EhCacheCacheManager is getting called and trying to autowire net.sf.ehcache.CacheManager cacheManager from it.
I am not able to understand why spring 4.3.x has old version of CacheManager instance of Ehcache, and not able to inject/autowire object. Please help me to solve this issue.

Please use StackOverflow or our mailing list to ask such questions.

Spring supports Ehcache 2 and 3. The EhCacheCacheManager is used for Ehcache 2. You should not use it. Ehcache 3 is configured through JCache so you should use the JCacheCacheManager instead.

Have a look here to see an example.

If I used ehcache.xml in the application still I need to programatically create cache manager bean and need to create cache objects?

Sorry, something went wrong.

@chandrasekhar4u you can use either jsr-107 api or ehcache3 api to load an ehcache.xml and retrieve your CacheManager and Caches from it :
http://www.ehcache.org/documentation/3.3/getting-started.html
http://www.ehcache.org/documentation/3.3/107.html

To use only configuration you can do something similar to:

application.properties

spring.cache.jcache.config=ehcache.xml

App.java:

@SpringBootApplication
@EnableCaching
public class App 
{
    public static void main( String[] args ) throws Exception {
        SpringApplication.run(App.class, args);
    }
}

Assuming you have spring-boot-starter-cache as a dependency.

The JCacheCacheConfiguration class will magically retrieve the ehcache.xml using the property and seeing the Ehcache is the JCache provider, initialize everything correctly.

@henri-tremblay Thank you for the reply,

I tried the same, and I autowired cacheManager in one of my spring service.
While application deployment I can see cache is getting loaded, but when I try to access pages, it's showing error Unsatisfied dependency expressed through field 'cacheManager'.

How can I access cacheManager and cache objects from it? (how application will come to know which cache manager implementation to invoke?)

You can use @Cacheable annotation to cache a method. But autowiring should work. Make sure you are autowiring the spring cache manager (org.springframework.cache.CacheManager), not the Ehcache one.

If that's already the case, I would need a full stack trace to help you.

That's the key for me:

Make sure you are autowiring the spring cache manager (org.springframework.cache.CacheManager)

Thanks @henri-tremblay.
