The cache with name or alias 'default' is no defined | Spring Boot 2.7.0

[90K2]

I have default and working setup

	implementation("com.google.code.simple-spring-memcached:spring-cache:4.1.3")
	implementation("com.google.code.simple-spring-memcached:xmemcached-provider:4.1.3")

with config :

@Configuration
@EnableCaching
class LocalSSMConfiguration : AbstractSSMConfiguration() {

    @Value("\${app.settings.cache.memcache-endpoint}")
    private val memCacheConnection: String = ""

    @Bean
    override fun defaultMemcachedClient(): CacheFactory? {
        val conf = CacheConfiguration()
        conf.isConsistentHashing = true
        val cf = CacheFactory()
        cf.cacheClientFactory = MemcacheClientFactoryImpl()
        cf.addressProvider = DefaultAddressProvider(memCacheConnection)
        cf.configuration = conf

        return cf
    }
}

but when bump Spring version 2.3.4 to 2.7.0 default cache bean stop creating on startup. Previously startup logs print success info

and everything working fine while 2.7.0 does not create memcached connection during startup and CacheBase.afterPropertiesSet() collect zero cashe beans

@ragnor Hello

So it seems that CacheBase.afterPropertiesSet is calling earler than Cache class appears in context. I like annotation approach and this library, so I have to make this dirty hack for Spring Boot 2.7.0

    @PostConstruct
    fun initCache() {
        val beanRegistry = context.autowireCapableBeanFactory as DefaultListableBeanFactory
        beanRegistry.removeBeanDefinition("cacheBase")
        context.getBeansOfType(Cache::class.java).values
        beanRegistry.registerBeanDefinition("cacheBase", RootBeanDefinition(CacheBase::class.java))
    }

note: this method must be placed in config class differ than local implementation of AbstractSSMConfiguration

Hi @90K2
Thank you for your report.
Do you have by any chance a sample simple project that reproduce the issue?
In spring-cache-integration-test module I have a few tests, all pass on spring 5.3.23 (the newest one) but xml configuration is used.

@ragnor thanks a lot for answer. In attached file I've placed small runnable app (kotlin).

build.gradle.kts: 

plugins {
    id("org.springframework.boot") version "2.3.4.RELEASE"
//    id("org.springframework.boot") version "2.7.0"
	id("io.spring.dependency-management") version "1.0.11.RELEASE"
	kotlin("jvm") version "1.3.72"
//	kotlin("jvm") version "1.7.0-RC2"
	kotlin("plugin.spring") version "1.3.72"
//	kotlin("plugin.spring") version "1.7.0-RC2"
}

So if we use uncommented set of versions, everything is well: beans creating on startup and XMemcachedClient open connect.
But if you change this set to commented-out , (springboot + jvm + spring) beans will not be prepared in right way.

sample

Thank you very much @90K2 for the sample. I've reproduced the issue. Looks like to main problem is some kind of circular dependencies in SSM:

• CacheBase looks for Cache beans
• Cache beans are created by CacheFactory that has CacheBase field autowired

I have to break it by removing CacheBase from CacheFactory and replacing by Settings. It is final solution that will go with next version. In the mean time you can use workaround, set spring.main.allow-circular-references: true
