问题描述

我正在开发具有JCS 1.3缓存的Web应用程序.

I am developping a web app with JCS 1.3 caching.

我需要在运行时从JVM属性编辑索引磁盘辅助高速缓存的DiskPath.

I need to edit the DiskPath of the Indexed Disk Auxiliary Cache at runtime from a JVM property.

您知道这样做的方法吗?

Do you know a way to do this ?

我设法创建了AuxiliaryCache对象，但是我不知道如何将其与我在cache.ccf中定义的所有区域连接起来.

I managed to create the AuxiliaryCache object but I don't know how to connect it with all my regions defined in cache.ccf.

以下是创建磁盘缓存的代码:

Here is the code creating the disk cache :

IndexedDiskCacheAttributes indexedCacheAttr = new IndexedDiskCacheAttributes();

indexedCacheAttr.setMaxKeySize(10000);
indexedCacheAttr.setMaxRecycleBinSize(10000);
indexedCacheAttr.setMaxPurgatorySize(10000);
indexedCacheAttr.setOptimizeAtRemoveCount(5000);

String cacheDir = System.getProperty("xxxxx");

if (cacheDir == null || cacheDir.trim().length() == 0) {
log.error("error:JCSManager xxxx.");
} else {
indexedCacheAttr.setDiskPath(cacheDir);
}


IndexedDiskCacheManager indexedCacheManager =
IndexedDiskCacheManager.getInstance(indexedCacheAttr);

// instance du cache disque
AuxiliaryCache auxCache = indexedCacheManager.getCache(region);

要获取区域，请使用以下内容:

To get a region I use the following :

JCS cache = JCS.getInstance(region);

请问一个主意?

推荐答案

我们终于从Web应用程序的类路径中提取了JCS conf文件(cache.ccf).

We finally extracted the JCS conf file (cache.ccf) from the classpath of the web app.

我为此文件添加了JVM属性.在访问JCS区域之前，我先加载属性，然后使用CompositeCacheManager类配置JCS.

I added a JVM property for this file. Before accessing to the JCS regions, I load the properties then use the CompositeCacheManager class to configure JCS.

String jcsConfFile = System.getProperty("XXXXXX");

if (jcsConfFile == null || jcsConfFile.trim().length() == 0) {
  log.error("error:JCSManager .........");
} else {
  Properties props = new Properties();

  try {
    // load a properties file
    props.load(new FileInputStream(jcsConfFile));
  } catch (IOException e) {
    log.error("error:JCSManager ........", e);
  }

  CompositeCacheManager ccm = CompositeCacheManager.getUnconfiguredInstance();

  ccm.configure(props);
}

//....
// later, ask for the region
JCS cache = JCS.getInstance(region);
