Hazelcast類路徑錯誤

我想使用voldemort商店來保存hazelcast中的數據。我實現了mapstore接口。當我嘗試在hazelcast中添加地圖項時，我得到這個異常。Hazelcast類路徑錯誤

這是我編輯過的hazelcast run.sh腳本，以便在類路徑中包含voldemort jar。

#!/bin/sh 
java -Djava.net.preferIPv4Stack=true -cp  ./:/home/gerrard/workspace/hazelcast/bin/:/home/gerrard/work/voldemort- 0.90.1/lib/:/home/gerrard/work/voldemort-0.90.1/dist/:/home/gerrard/work/voldemort- 0.90.1/bin/:../lib/hazelcast-2.0.1.jar com.hazelcast.examples.TestApp

我也在hazelcast.xml文件中添加了我的實現類。

我還在hazelcast-2.0.1.jar的清單文件中添加了一個類路徑條目。

即使這樣，當我嘗試添加一個條目時，它會給出此noclassdef發現的錯誤。它試圖找到的類肯定是在我添加到類路徑的voldemort文件夾中。我仍然不知道問題是什麼。有人可以提出其他解決方案嗎？謝謝。

您可以嘗試Hazelcast配置並自己設置工廠對象。

// Build the config from xml file you have in the classpath 
Config config = new XmlConfigBuilder().build(); 
MapStoreConfig msc = new MapStoreConfig.. 
msc.setFactoryImplementation(new StoreClientFactory()); 
MapConfig mapConfig = new MapConfig.. 
mapConfig.setMapStoreConfig(msc); 
config.addMapConfig(mapconfig); 

// init Hazelcast with this configuration 
// make sure you call init fore any other Hazelcast operation!! 
Hazelcast.init(config); 

// then access to your map 
Map map = Hazelcast.getMap("mymap");
