第一种：实现org.springframework.web.servlet.HandlerExceptionResolver这个接口
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Repository;
import org.springframework.stereotype.Service;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.view.json.MappingJacksonJsonView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@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());
//当使用是jackson2.x的时候使用MappingJackson2JsonView，这里是1.9。
modelAndView.addObject("status","500");
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;
}
}
第二种：加注解方式
@ControllerAdvice(annotations = RestController.class)
public class GlobalExceptionHandler {
@Autowired
private HttpServletRequest request;
@ResponseBody
@org.springframework.web.bind.annotation.ExceptionHandler(value=Exception.class)
public String allExceptionHandler(Exception exception)
{
//全局异常逻辑
}
