1、maven

<dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-cache</artifactId>
    </dependency>
    
    <dependency>
    	<groupId>net.sf.ehcache</groupId>
    	<artifactId>ehcache</artifactId>
    </dependency>
    
    <dependency>
    	<groupId>org.springframework.boot</groupId>
    	<artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

2、application.properties

#设置日志显示级别
    logging.level.cn.kexq.dao=debug
    
    spring.jpa.hibernate.ddl-auto=update
    spring.jpa.show-sql=true
    spring.cache.ehcache.cofnig=ehcache.xml

3、cache.xml

<?xml version="1.0" encoding="utf-8" ?>
    <ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
        <diskStore path="java.io.tmpdir"/>
    
        <defaultCache
                maxElementsInMemory="10000"
                eternal="false"
                timeToIdleSeconds="120"
                timeToLiveSeconds="120"
                maxElementsOnDisk="10000000"
                diskExpiryThreadIntervalSeconds="120"
                memoryStoreEvictionPolicy="LRU">
            <persistence strategy="localTempSwap"/>
        </defaultCache>
    
        <cache name="demoCache"
               maxEntriesLocalHeap="1000"
               maxEntriesLocalDisk="100"
               eternal="false"
               diskSpoolBufferSizeMB="30"
               timeToIdleSeconds="300"
               timeToLiveSeconds="600"
               memoryStoreEvictionPolicy="LFU"
               transactionalMode="off">
            <persistence strategy="localTempSwap"/>
        </cache>
    
    </ehcache>

4、写入缓存  
@Cacheable(value = “demoCache”)

5、启动类

@SpringBootApplication
    @MapperScan("cn.kexq.dao")
    @EnableCaching
    public class Springboot1Application {
    	public static void main(String[] args) {
    		SpringApplication.run(Springboot1Application.class, args);
    	}
    }
