[Springboot] Springboot integrate Ehcache

Just a line item on the recording technique used under ......

EhCache is a pure Java caching framework of the process, with fast, lean, etc., Hibernate is the default CacheProvider.

Ehcache features

(1) quick and simple, with a variety of caching policy

(2) There are two levels to the data cache memory and disk, cache data is written to disk in the process of restarting a virtual machine

(3) via RMI, etc. can be inserted into the distributed API caches

(4) the listening socket having a cache and a cache manager

(5) Cache Manager supports multiple instances, and one example of a plurality of cache area. Hibernate and provides a cache implementation

The project involves a packet protocol conversion, to use all kinds of api or message format template needs to cache memory in order to reduce the time-consuming conversion messages, select Ehcache is more suitable, fast, simple

Ado, take a little demo

A, Springboot integrate Ehcache

Configuration dependency

　　　　pom.xml dependency added ehcache

<groupId>net.sf.ehcache</groupId>

<artifactId>ehcache</artifactId>

　　</dependency>

　　2. Configure ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd"

updateCheck="false">

<!--

Disk storage: the objects in the cache temporarily not in use, transfer to the hard disk, similar to the Windows system virtual memory

path: Specifies objects stored on the hard disk path

You can configure directory path are:

user.home (the user's home directory)

user.dir (user's current working directory)

java.io.tmpdir (default temporary directory)

ehcache.disk.store.dir ( Ehcache configuration directory)

Absolute path (eg: D: \\ Ehcache)

View path method: String tmpDir = System.getProperty ( "java.io.tmpdir");

-->

<!--

eternal: the content is permanently stored in the cache memory; when the value is set to true, and the two values timeToIdleSeconds timeToLiveSeconds properties would be ineffective

maxElementsInMemory: an upper limit on the cache, how many records the object store up

timeToIdleSeconds: After the cache is created, the time interval when the date of the last visit to the cache of failure; the default value is 0, that is, idle time can be infinite

timeToLiveSeconds: Cache inception interval of time until the expiration date; the default is 0. survival time is infinite objects

overflowToDisk: If the data memory exceeds maxElementsInMemory, whether to use disk storage

diskPersistent: disk storage entry is stored permanently

maxElementsOnDisk: The maximum number of hard disk cache

memoryStoreEvictionPolicy: The default policy is LRU (least recently used). You can set FIFO (First In First Out) or LFU (rarely used)

-->

<cache name="usercache" eternal="false" maxElementsInMemory="10000"

overflowToDisk="true" diskPersistent="false" maxElementsOnDisk="0" timeToIdleSeconds="0" timeToLiveSeconds="0"

memoryStoreEvictionPolicy="LRU" />

</ehcache>

3. Configure enable ehcache comment

1 @SpringBootApplication
2 @EnableCaching
3 public class App {
4     public static void main(String[] args) {
5         SpringApplication.run(App.class, args);
6     }
7 }
