In this article, I’ll record the development experience about how to use guava cache manager under spring framework, mainly about the common properties, main process and give a sample.

• Add schema in xml to let spring recognize cache tags.

xmlns:cache="http://www.springframework.org/schema/cache

http://www.springframework.org/schema/cache


http://www.springframework.org/schema/cache/spring-cache.xsd"

 

• Enbale cache annotation and leave expansion room for configurations.

<context:annotation-config />
<cache:annotation-driven />

 

• Configure cache manager.

    <bean id="cacheManager" class="org.springframework.cache.guava.GuavaCacheManager">
        <property name="cacheBuilderSpec">
            <bean class="com.google.common.cache.CacheBuilderSpec"
                factory-method="parse">
                <constructor-arg name="cacheBuilderSpecification"
                    value="expireAfterWrite=3600s" /> # calculate the effective time from the first arrival of the visit and do not redo caculation during the period 3600s.
            </bean>
        </property>
    </bean>

 

• Use cache manager.

  @Cacheable(cacheNames = "receiveTicketInfo", cacheManager = "cacheManager", key = "#accessToken")
  public JSONObject receiveTicketInfo(String accessToken) {

    log.info("Trace: WechatShareServiceImpl.receiveTicketInfo(String accessToken)");
    ...
    
}

 

• Dependencies required.

<dependency>
    <groupId>org.springframework</groupId>
   <artifactId>spring-context-support</artifactId>
   <version>${spring.version}</version>
</dependency>

<!-- https://mvnrepository.com/artifact/com.google.guava/guava -->
<dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guava</artifactId>
    <version>19.0</version>
</dependency>
