springMVC全局异常

记录一下springMVC的异常处理方法，好脑子不如烂笔头

1，没有使用全局异常

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;
    }

}
