找不到可缓存(在 EhCache 中)



我有以下结构:

public List<Integer> getCurrentRoleDetails(){
   return getRoleCached(getCurrentRole());
}
@Cacheable(value = "roleWrite", key = "#role.getRoleId()")
private final List<Integer> getRoleCached(final Role role) {
    System.out.println("role...= " + role.getRoleId());

和配置

@EnableCaching
@Configuration
public class CacheConf {
    // EhCache based CacheManager, most commonly used in Enterprise
    // applications.
    @Bean
    public CacheManager cacheManager() {
        final EhcacheCachingProvider provider = (EhcacheCachingProvider) Caching.getCachingProvider();
        final Map<String, CacheConfiguration<?, ?>> caches = new HashMap<>();
        caches.put("roleWrite", getCache());
        final DefaultConfiguration configuration = new DefaultConfiguration(caches, provider.getDefaultClassLoader());
        return new JCacheCacheManager(provider.getCacheManager(provider.getDefaultURI(), configuration));
    }
    private CacheConfiguration<?, ?> getCache() {
        final ResourcePoolsBuilder res = ResourcePoolsBuilder.heap(100);
        // Spring does not allow anything else than Objects...
        final CacheConfigurationBuilder<Object, Object> newCacheConfigurationBuilder = CacheConfigurationBuilder
                .newCacheConfigurationBuilder(Object.class, Object.class, res);
        return newCacheConfigurationBuilder.build();
    }

与实体:

@Data // lombok generates the Getter and Setters
public class Role implements Serializable {
    private static final long serialVersionUID = 1L;
    @Id
    @Column(name = "id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Integer roleId;

但不知何故,缓存从未被击中。结论之所以出现,是因为我可以使用相同的角色调用getRoleCached,但尽管如此,sysout打印新行。

我的q:如何正确指定key以获得所需的结果?

更新:在提示之后,我发现public方法是通过 Spring 代理调用的,而内部(类的(是直接调用的。当直接调用时,Spring 不会有任何进一步的拦截 完成 ==> 不会检查Cache,即不应用。重构和移动请求的方法修复了我的问题。

@Cacheable使用Spring AOP代理,因此您不能在私有方法上使用@Cacheable。 尝试公共方法
