SpringBoot 配置全局异常处理器

1. 创建一个全局异常处理类
2. 类上加上@ControllerAdvice注解
3. 定义一个异常处理方法 方法上加@ExceptionHandler(value = Exception.class)
4. 例子如下:

@ControllerAdvice
public class GlobalWebInterceptor {
    @ExceptionHandler(value = Exception.class)
    public ModelAndView intercept(HttpServletRequest req, Exception e) {
        ModelAndView mav = new ModelAndView();
        mav.addObject("exception", e);
        mav.setViewName("error");
        return mav;
    }
}
