與物化的彈簧引導

我使用彈簧引導與物化作爲持久層。它正在部署到Flexible App Engine。在每個實體我有一個塊：與物化的彈簧引導

static { 
    ObjectifyService.register(LsUser.class); 
}

試圖運行從Controller類的代碼：當運行它

ObjectifyService.run(new VoidWork() { 
    @Override   
    public void vrun() { 
     ofy.save().entity(new User())).now();   
    }  
});

我有一個錯誤：

java.lang.NullPointerException: No API environment is registered for this thread.
