code: private static void initEngine() {
  		engine.setDevMode(constants.getDevMode());
  		
  		// 避免在某些环境下 webRootPath 值为 blank 时无法启动项目
  		if (StrKit.notBlank(PathKit.getWebRootPath())) {
  			engine.setBaseTemplatePath(PathKit.getWebRootPath());
  		}
  	}
docs: Set the default base template path and devMode by JFinal before configEngine(engine) invoked
  They can be reconfigured in configEngine(engine)
