考虑内存中默认的H2数据库

如果我错了，在配置中没有任何地方定义数据源的 bean 被用作 refernce.Correct 我，但根据我的理解，缓存存储的作用只是将数据加载到缓存和从缓存中加载数据，并且确实不处理选择持久化 store.How ignite 了解持久化存储吗？

Answer 1

缓存存储负责从数据库和 read/write-through 加载数据。详情见[1]。

如果使用CacheJdbcPojoStore，可以提供数据源Springbean的名称，store会自动取：

CacheJdbcPojoStoreFactory<Long, Person> storeFactory = new CacheJdbcPojoStoreFactory<>();
storeFactory.setDataSourceBean("mysql-example-db");
