How to achieve data persistence in ehcache? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Ehcache, like other caches, requires flush or shutdown to persist to the hard disk.

The data file for .data and the index file for .index are generated to facilitate restart and recovery.

Method 1:

Net.sf.ehcache.constructs.web.ShutdownListener

Method 2:

Execute a flush every time you set

Net.sf.ehcache.Cache ehCache = (net.sf.ehcache.Cache) cache.getNativeCache (); ehCache.flush ()

Method 3:

MaxElementsInMemory is set to 1century overflowToDisk and set to true. As long as there is a cache element, it is directly stored on the hard disk.

Other:

Persistence: represents the persistence of the Cache, which has only one attribute, strategy, which represents the persistence policy corresponding to the current Cache. The optional values are as follows:

LocalRestartable: this strategy is only useful for Enterprise Ehcache. It can persist the elements in heap memory or non-heap memory to the hard disk during reboot, and then recover the elements from the hard disk to memory after reboot.

This is the answer to the question about how to achieve data persistence in ehcache. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel to learn more about it.
