J2Cache 2.3.12 released, supporting L2 cache read-only mode

Since the launch of J2Cache, many people have hoped to provide the read-only mode of the second-level cache, which means that the application can only read data from the Redis second-level cache, and is not allowed to write any data, including when the first-level cache fails. Clear the data in the second level cache. Such developers generally use a separate process to update cache data and achieve cache synchronization within the cluster.

Considering that many developers have this demand, this updated version is hereby released to support the read-only mode of the second-level cache. The specific implementation method is relatively simple. The core code of J2Cache is not moved, but a ReadonlyRedisCacheProvider is overloaded to shield the write method of the cache.

To use read-only mode, just upgrade to version 2.3.12 and modify the configuration as follows:

j2cache.L2.provider_class = readonly-redis

And add  j2cache.L2.config_section = redis to the configuration to use the existing redis configuration.
