彈簧@Cacheable複雜鍵仍然執行

Question

用於@Cacheable在彈簧的使用（3.1）我有以下：

彈簧：

<cache:annotation-driven /> 
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager" p:cache-manager-ref="ehcache" /> 
<!-- Ehcache library setup --> 
<bean id="ehcache" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" 
    p:config-location="classpath:ehcache.xml" /> 

的Maven：

<dependency> 
     <groupId>net.sf.ehcache</groupId> 
     <artifactId>ehcache-core</artifactId> 
     <version>2.5.3</version> 
    </dependency> 

待緩存的方法：

@Cacheable(value="cahceName", key="concat(#param1).concat(‘-’).concat(#param2)") 
    public String cachedMethod(String param1,String param2) 

唉，當我調試代碼時，即使param1和param2相同（即不使用cahce），我也會看到緩存的方法被多次調用。

任何想法？

Answer 1

關鍵顯示不正確 -

您可能意味着 - @Cacheable(value="cacheName", key="#param1.concat(‘-’).concat(#param2)")

此外，如果編譯沒有調試信息，參數1完成，參數2參數名稱將不會提供給表達式求值。相反，你可以參考他們使用P0，P1等這樣：

@Cacheable(value="cahceName", key="#p0.concat('-').concat(#p1)")

更新：

我這裏有一個頁面的測試，證明了這是如何工作 - https://gist.github.com/3315275
