想不报错 只需要在后面加个 true
getBean(Class beanClass, boolean skipConvertError)
getBean(beanClass, true)
不贴异常信息还得猜。。
看看源码：打个断点进去看看吧~

	public static  T injectBean(Class beanClass, HttpServletRequest request, boolean skipConvertError) {
		String beanName = beanClass.getSimpleName();
		return (T)injectBean(beanClass, StrKit.firstCharToLowerCase(beanName), request, skipConvertError);
	}

		TypeConverter converter = TypeConverter.me();
