Cache系列：spring-cache简单三步快速应用ehcache3.x-jcache缓存（spring4.x）

前言：本项目基于spring4.x构建，使用ehcache3.5.2和JCache(jsr107规范)

一、依赖

    除了ehcache和cache-api外，注意引用spring-context-support

1.                    
2.                      <dependency>
3.                          <groupId>org.springframeworkgroupId>
4.                          <artifactId>spring-context-supportartifactId>
5.                          <version>4.3.16.RELEASEversion>
6.                      dependency>
7.      <dependency>
8.      <groupId>org.ehcachegroupId>
9.      <artifactId>ehcacheartifactId>
10.      <version>3.5.2version>
11. dependency>
12. <dependency>
13.      <groupId>javax.cachegroupId>
14.      <artifactId>cache-apiartifactId>
15.      <version>1.0.0version>
16. dependency>

 

二、配置

1、ehcache配置

1. "1.0" encoding="UTF-8"?>
2. <ehcache:config
3. xmlns:ehcache="http://www.ehcache.org/v3"
4. xmlns:jcache="http://www.ehcache.org/v3/jsr107">
5.  
6. <ehcache:service>
7. <jcache:defaults>
8. <jcache:cache name="default" template="myDefaultTemplate"/>
9. jcache:defaults>
10. ehcache:service>
11.  
12. <ehcache:cache alias="allCameraCache">
13. <ehcache:key-type copier="org.ehcache.impl.copy.SerializingCopier">java.lang.Stringehcache:key-type>
14. <ehcache:value-type copier="org.ehcache.impl.copy.SerializingCopier">java.lang.Stringehcache:value-type>
15. <ehcache:expiry>
16. <ehcache:tti unit="minutes">20ehcache:tti>
17. ehcache:expiry>
18. <ehcache:heap unit="entries">200ehcache:heap>
19. ehcache:cache>
20.  
22. <ehcache:cache alias="cameraCache" uses-template="myDefaultTemplate">
23. <ehcache:key-type>java.lang.Objectehcache:key-type>
24. <ehcache:value-type>java.lang.Objectehcache:value-type>
25. <ehcache:expiry>
26. <ehcache:tti unit="minutes">30ehcache:tti>
27. ehcache:expiry>
28. <ehcache:heap unit="entries">500ehcache:heap>
29. ehcache:cache>
30.  
32. <ehcache:cache-template name="myDefaultTemplate">
33. <ehcache:expiry>
34. <ehcache:none/>
35. ehcache:expiry>
36. ehcache:cache-template>
37.  
38. ehcache:config>

 

2、spring配置

1. "1.0" encoding="UTF-8"?>
2. <beans xmlns="http://www.springframework.org/schema/beans"
3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4. xmlns:context="http://www.springframework.org/schema/context"
5. xmlns:cache="http://www.springframework.org/schema/cache"
6. xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
7. http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
8. http://www.springframework.org/schema/cache http://www.springframework.org/schema/cache/spring-cache.xsd">
10. <cache:annotation-driven cache-manager="cacheManager" />
11. <context:component-scan base-package="cc.eguid.cache" />
13. <bean id="jCacheManager" class="org.springframework.cache.jcache.JCacheManagerFactoryBean">
14.      <property name="cacheManagerUri" value="classpath:config/ehcache.xml" />
15. bean>
16. <bean id="cacheManager" class="org.springframework.cache.jcache.JCacheCacheManager">
17. <property name="cacheManager" ref="jCacheManager" />
18. bean>
19. beans>

 

三、使缓存生效

1、注解方式使用

@Cacheable(value="cameraCache",key="#userid")

public String getCameraList(String userid,Integer otherparam) {

...

}

spring-cache的注解比较简单就不再赘述了。
