1.添加依赖

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-cache</artifactId></dependency><dependency><groupId>net.sf.ehcache</groupId><artifactId>ehcache</artifactId><version>2.10.4</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId><version>2.1.6.RELEASE</version></dependency><dependency><groupId>net.oschina.j2cache</groupId><artifactId>j2cache-spring-boot2-starter</artifactId><version>2.7.6-release</version></dependency><dependency><groupId>net.oschina.j2cache</groupId><artifactId>j2cache-core</artifactId><version>2.7.7-release</version></dependency>

application.yml 增加配置

spring: cache:ehcache:config: classpath:ehcache/ehcache-shiro.xml# j2cache配置文件路径j2cache:config-location: classpath:/ehcache/j2cache-${spring.profiles.active}.propertiescache-clean-mode: activeopen-spring-cache: true

2.添加配置

配置文件结构

ehcache-shiro.xml

<?xml version="1.0" encoding="UTF-8"?><ehcache name="jeefast" updateCheck="false"><diskStore path="java.io.tmpdir"/><defaultCachemaxEntriesLocalHeap="1000"eternal="false"timeToIdleSeconds="3600"timeToLiveSeconds="3600"overflowToDisk="false"></defaultCache><cache name="loginRecordCache"maxEntriesLocalHeap="2000"eternal="false"timeToIdleSeconds="600"timeToLiveSeconds="0"overflowToDisk="false"statistics="true"></cache><cache name="sys-userCache"maxEntriesLocalHeap="10000"overflowToDisk="false"eternal="false"diskPersistent="false"timeToLiveSeconds="0"timeToIdleSeconds="0"statistics="true"></cache><cache name="shiro-activeSessionCache"maxElementsInMemory="10000"overflowToDisk="true"eternal="true"timeToLiveSeconds="0"timeToIdleSeconds="0"diskPersistent="true"diskExpiryThreadIntervalSeconds="600"></cache></ehcache>

ehcache3.xml

<?xml version="1.0" encoding="UTF-8"?><configxmlns:xsi='/2001/XMLSchema-instance'xmlns='/v3'xsi:schemaLocation="/v3 /schema/ehcache-core.xsd"><cache-template name="default"><key-type>java.lang.String</key-type><value-type>java.io.Serializable</value-type><expiry><ttl unit="seconds">1800</ttl></expiry><resources><heap>1000</heap><offheap unit="MB">100</offheap></resources></cache-template><cache alias="default" uses-template="default"/></config>
