与物化的弹簧引导

我使用弹簧引导与物化作为持久层。它正在部署到Flexible App Engine。在每个实体我有一个块：与物化的弹簧引导

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

试图运行从Controller类的代码：当运行它

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

我有一个错误：

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