Question

我们已经按照JSR107规范实现了自定义缓存。

我们面临的问题是，我们无法通过在spring.cache.jcache.provider文件的application.properties标签中提及自定义缓存提供程序来在我们的spring应用程序中加载缓存。

当前下面是我们的缓存提供程序和Cachemanager的模板代码。我们已经提取了实现代码。

MyCacheProvider.java:

    package com.mycache;

    public class MyCacheProvider implements CachingProvider {

        public MyCacheProvider () {}

        // Overriden methods

}

MyCacheManager.java:

package com.mycache;

public class MyCacheManager implements CacheManager{

    public MyCacheManager (Object ctx, CachingProvider cachingProvider, URI uri, ClassLoader classLoader, Properties properties) { }

    // Overriden methods

}

application.properties文件

spring.cache.jcache.provider=com.mycache.MyCacheProvider 
spring.cache.type=jcache

弹簧输出：
