我们使用Rythm引擎并且偶尔会出现以下错误。它在90％的时间内都能正常工作。我们为每个线程创建一个实例

这是我们创建引擎的方式
public class RythmEngineUtil {
/**
* clear the rythm Pre compiled data
*/
static{
try {
File dir = new File("./", "__rythm");
if(!dir.exists()){
dir.mkdir();
}else{
deleteDirAndChildren(dir);
}
}catch(Exception e){
e.printStackTrace();
}
}
private static void deleteDirAndChildren(File dir) {
if (dir.isDirectory()) {
String[] children = dir.list();
for (int i = 0; i < children.length; i++) {
new File(dir, children[i]).delete();
}
}
}
/**
* Initilize Rythm Engine
*/
private static ThreadLocal<RythmEngine> rythmEngine = new ThreadLocal<RythmEngine>() {
protected RythmEngine initialValue() {
Map<String, Object> conf = new HashMap<String, Object>();
conf.put("rythm.codegen.compact", false);
conf.put("engine.precompile_mode", true);
conf.put("engine.load_precompiled", true);
conf.put("home.template","xyz/some");
conf.put("home.precompiled.dir", new File("./", "__rythm"));
RythmEngine engine = new RythmEngine(conf);
System.out.println("Got new RythmEngine -" + engine.getId());
return engine;
}
};
public static RythmEngine getEngine() {
return rythmEngine.get();
}
private RythmEngineUtil() {
}
private static RythmEngineUtil _instance = new RythmEngineUtil();
public static RythmEngineUtil getInstance() {
return _instance;
}
}
然后像
一样使用它RythmEngineUtil.getEngine（）
