SpringBoot整合guava缓存

1.pom文件

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-cache</artifactId>
        </dependency>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>21.0</version>
        </dependency>

2.yaml配置文件

#spring配置
spring:
  application:
    name: cardmember
  datasource:
       
  cache:
    type: guava
    cache-names: merchantDetail,selConfig #缓存名字
    guava:
      spec: maximumSize=500,expireAfterWrite=5m

springboot支持的缓存类型

public enum CacheType {
    GENERIC,
    JCACHE,
    EHCACHE,
    HAZELCAST,
    INFINISPAN,
    COUCHBASE,
    REDIS,
    CAFFEINE,
    /** @deprecated */
    @Deprecated
    GUAVA,
    SIMPLE,
    NONE;

    private CacheType() {
    }
}

3.service调用

 @Cacheable(value = "merchantDetail")
    public Map checkMerchantInfo(String merchantID) {
        Map<String, String> map = merchantMapper.findAppCardMerchantById(merchantID);
        logger.info("------商户详情从数据库中获取-----:{}", map);
        return map;
    }

最基础运用，不需要其他多余配置。
