在springboot3.x版本中，缓存管理的相关标签有所改动，[官方文档][Link 1]中对于支持缓存提供者的部分示例如下，不再有一个ehcache标签指定ehcache，而是统一为jcache（java缓存通用标准）即可识别。

# Only necessary if more than one provider is present
    spring:
      cache:
        jcache:
          provider: "com.example.MyCachingProvider"
          config: "classpath:example.xml"

spring官方说明如下

> [JCache][] is bootstrapped through the presence of a `javax.cache.spi.CachingProvider` on the classpath (that is, a JSR-107 compliant caching library exists on the classpath), and the `JCacheCacheManager` is provided by the `spring-boot-starter-cache` “Starter”. Various compliant libraries are available, and Spring Boot provides dependency management for Ehcache 3, Hazelcast, and Infinispan. Any other compliant library can be added as well.
> 
> It might happen that more than one provider is present, in which case the provider must be explicitly specified. Even if the JSR-107 standard does not enforce a standardized way to define the location of the configuration file, Spring Boot does its best to accommodate setting a cache with implementation details, as shown in the following example:

翻译

> JCache是通过classpath上存在javax.cache.spi.CachingProvider来引导的（也就是说，classpath上存在一个符合JSR-107标准的缓存库），JCacheCacheManager由spring-boot-starter-cache "启动器 "提供。有各种兼容的库，Spring Boot为Ehcache 3、Hazelcast和Infinispan提供依赖性管理。也可以添加任何其他兼容的库。

> 可能会出现不止一个提供者的情况，在这种情况下，必须明确指定提供者。即使JSR-107标准没有强制要求以标准化的方式定义配置文件的位置，Spring Boot也会尽力适应设置缓存的实现细节，如下面的例子所示：
