问题描述

关注我可以在项目中使用缓存，但是如何配置guava来定义每个缓存名称的过期时间或大小？

Following the spring documentation about cache I could use cache on my project, but how can I configure guava to define a expired time or size per cache name?

applicationConfig.xml

<bean id="cacheManager" class="org.springframework.cache.guava.GuavaCacheManager"/>

Foo.java

@Cacheable(value="courses", key="#user.id")
public List<Course> getCoursesByUser(User user) {
    ...
}

推荐答案

您可以单独配置缓存。请参阅

You can configure caches separately. See Spring Guava cache

@Bean
public CacheManager cacheManager() {
    SimpleCacheManager simpleCacheManager = new SimpleCacheManager();
    GuavaCache bookCache = new GuavaCache("book", CacheBuilder.newBuilder().build());
    GuavaCache booksExpirableCache = new GuavaCache("books", CacheBuilder.newBuilder()
            .expireAfterAccess(30, TimeUnit.MINUTES)
            .build());
    simpleCacheManager.setCaches(Arrays.asList(bookCache, booksExpirableCache));
    return simpleCacheManager;
}
