设置springmvc全局异常

设置全局异常，将异常信息指定内容展示给前端页面，保证程序的安全性

@Slf4j
@Component
public class ExceptionResolver implements HandlerExceptionResolver {
    @Override
    public ModelAndView resolveException(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
        log.error("{} Exception",httpServletRequest.getRequestURI(),e);
        ModelAndView modelAndView = new ModelAndView(new MappingJacksonJsonView());

        //当使用Jackson 2.x.时，使用对应的MappingJackson2JsonView, 这里使用的是1.9
        modelAndView.addObject("status",ResponseCode.ERROR.getCode());
        modelAndView.addObject("msg","接口异常，详情请查看服务端日志的异常信息");
        modelAndView.addObject("data", e.toString());

        return modelAndView;
    }
}
