在android adain中创建EHCache实例时出现java.lang.ExceptionInInitializeError错误

我试图在Android中使用ehCache，并得到以下错误

08-01 10:26:11.308 1645-1645/com.example.ehcache.ehcache_test E/AndroidRuntime: FATAL EXCEPTION: main

这是我试图初始化的代码

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        CacheManager manager = CacheManager.getInstance();

        try {
            manager.addCache("myCache");
            Cache myCache = manager.getCache("myCache");
            myCache.put(new Element("hoge", "HOGE"));

            myCache = manager.getCache("myCache");
            Element element = myCache.get("hoge");
            System.out.println("myCache.hoge = " + element.getObjectValue());
        } finally {
            manager.shutdown();
        }

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
}

ehcache.xml

<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">

        maxEntriesLocalHeap="0">
    </cache>
</ehcache>

这个问题以前已经定义，但尚未解决。

我将等待任何答案。

我们需要CacheException的源来告诉您发生了什么。然而，如果它不起作用，我也不会感到惊讶。不再维护Ehcache 2.x

您可能想试试Ehcache 3.x。如果它不起作用，我们将立即修复它。：-）
