全局异常处理器

处理思路：

创建全局异常处理器

public class GlobalExceptionResolver implements HandlerExceptionResolver {

	private static final Logger logger = LoggerFactory.getLogger(GlobalExceptionResolver.class);
	@Override
	public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler,
			Exception ex) {
		//打印控制台
		ex.printStackTrace();
		//写日志
		logger.debug("测试输出日志。。。。");
		logger.error("系统发生异常。。。。",ex);
		//发邮件，发短信
        //（JMail，购买短信，使用第三方接口）
		//显示错误页面
		ModelAndView modelAndView = new ModelAndView();
		modelAndView.setViewName("error/exception");
		return modelAndView;
	}

}

配置文件springmvc.xml

log4j.properties
