Spring cache 如果特定异常，缓存名称必须是非空的

Question

我一直在尝试为我的项目实施基本缓存，但在部署应用程序时出现错误。

服务器：Tomcat7

Spring版本：4.1.4

我尝试使用不同的缓存管理器配置，但没有成功

这里是 xml 配置

<cache:annotation-driven />
    <bean id="cacheManager" class="org.springframework.cache.concurrent.ConcurrentMapCacheManager">
        <constructor-arg>
            <set>
                <value>cache1</value>
                <value>cache2</value>
                <value>cache3</value>
            </set>
        </constructor-arg>
    </bean>

我还尝试了 spring 文档

上给出的配置

<bean id="cacheManager" class="org.springframework.cache.support.SimpleCacheManager">
    <property name="caches">
        <set>
            <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean" p:name="cache1"/>
            <bean class="org.springframework.cache.concurrent.ConcurrentMapCacheFactoryBean" p:name="cache2"/>
        </set>
    </property>
</bean>

我正在尝试缓存的函数

@Cacheable(value = "cache1", key = "#root.methodName")
    public List<ObjectDetails> getAllObjects() {
        return objectDao.getAllObjects();
    }

任何人都可以指出实施缓存时可能出现此问题的地方。

感谢 Stéphane Nicoll，我才得以找到问题

Cache name must be non-null if specified

这意味着我提供了一个空字符串来代替这样的缓存名称。

@Cacheable(value = "", key = "#root.methodName")
    public List<ObjectDetails> getAllObjects() {
        return objectDao.getAllObjects();
    }

提供了合适的名称，问题已解决。谢谢
