Java 如何在ehCache.xml中声明的ehCache decorator中传递依赖项

我想找到一种在ehCache decorator类中使用Spring依赖项注入的好方法。 我的ehcache.xml具有以下缓存配置：

<cache name="MY_CACHE"
       memoryStoreEvictionPolicy="LRU">
    <cacheDecoratorFactory class="org.company.MyCacheDecoratorFactory"/>
</cache>

因此，我不能使用@Autowire直接注入MyDependency，因为decorator是通过我的ehcache.xml中的

标记实例化的

为了能够使用spring上下文，我实现了

ApplicationContextAware

接口。问题在于

setApplicationContext（）

方法是在

createdecoratedhcache（）

之后调用的，并且在实例化

MyUpdateingCacheEntryFactory

时无法设置依赖项

如何将我的spring依赖项正确地传递给装饰器？

好的，我可以通过spring以以下方式完成这项工作：

我已经从ehcache.xml中删除了

标记，并添加了一个缓存配置bean，该bean使用缓存管理器在初始化时用decorator替换缓存：

@Component
public class CacheInitConfigurer implements InitializingBean {
    @Autowired
    private CacheManager cacheManager;
    @Autowired
    private MyCacheDecoratorFactory decoratorFactory;

    @Override
    public void afterPropertiesSet() throws Exception {
        final Ehcache myCache = cacheManager.getEhcache("MY_CACHE");
        cacheManager.replaceCacheWithDecoratedCache(myCache,
            decoratorFactory.createDefaultDecoratedEhcache(myCache, null));
    }
}

我将我的CacheDecoratorFactory更改如下：

@Component
public class MyCacheDecoratorFactory extends CacheDecoratorFactory {
    @Autowired
    private MyUpdatingCacheEntryFactory myUpdatingCacheEntryFactory;

    @Override
    public Ehcache createDecoratedEhcache(final Ehcache ehcache, final Properties properties) {
        final SelfPopulatingCache selfPopulatingCache = new UpdatingSelfPopulatingCache(ehcache,
                myUpdatingCacheEntryFactory);
        selfPopulatingCache.setTimeoutMillis(30 * 1000);

        return selfPopulatingCache;
    }

    @Override
    public Ehcache createDefaultDecoratedEhcache(final Ehcache ehcache, final Properties properties) {
        return this.createDecoratedEhcache(ehcache, properties);
    }
}

它对我有用。如果有人有更好的解决方案，请让我知道

@Component
public class MyCacheDecoratorFactory extends CacheDecoratorFactory {
    @Autowired
    private MyUpdatingCacheEntryFactory myUpdatingCacheEntryFactory;

    @Override
    public Ehcache createDecoratedEhcache(final Ehcache ehcache, final Properties properties) {
        final SelfPopulatingCache selfPopulatingCache = new UpdatingSelfPopulatingCache(ehcache,
                myUpdatingCacheEntryFactory);
        selfPopulatingCache.setTimeoutMillis(30 * 1000);

        return selfPopulatingCache;
    }

    @Override
    public Ehcache createDefaultDecoratedEhcache(final Ehcache ehcache, final Properties properties) {
        return this.createDecoratedEhcache(ehcache, properties);
    }
}
