##### 2，使用全局异常 #####

@sl4j注解使用的是lombok

@Component则是将此类交给spring容器处理

jackson的依赖使用的是

<dependency>
      <groupId>org.codehaus.jackson</groupId>
      <artifactId>jackson-mapper-asl</artifactId>
      <version>1.9.12</version>
    </dependency>

@Slf4j
    @Component
    public class ExceptionResolver implements HandlerExceptionResolver{
        @Override
        public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response,
                                             Object o, Exception exception) {
            log.error("{} Exception",request.getRequestURI(),exception);
            //当使用时jackson2.x的时候 使用MappingJackson2JsonView，当前使用的是1.9
            ModelAndView modelAndView = new ModelAndView(new MappingJacksonJsonView());
            modelAndView.addObject("status",ResponseCode.ERROR.getCode());
            modelAndView.addObject("msg","接口异常");
            modelAndView.addObject("data", exception.toString());
    
            return modelAndView;
        }
    }

public enum ResponseCode {
    
        SUCCESS(0,"SUCCESS"),
        ERROR(1,"ERROR"),
        NEED_LOGIN(10,"NEED_LOGIN"),
        ILLEGAL_ARGUMENT(2,"ILLEGAL_ARGUMENT");
    
        private final int code;
        private final String desc;
    
    
        ResponseCode(int code,String desc){
            this.code = code;
            this.desc = desc;
        }
    
        public int getCode(){
            return code;
        }
        public String getDesc(){
            return desc;
        }
    
    }
