springboot异常统一处理

修改springboot默认返回的异常消息结构

{
	"timestamp": "2021-11-05 12:36:07",
	"status": 404,
	"error": "Not Found",
	"path": "/xxx/ooo123"
}

修改这个结构体
①项目配置文件中增加

 mvc:
    throw-exception-if-no-handler-found: true
  resources:
    add-mappings: false

②增加异常跳转控制器

@ControllerAdvice
@Slf4j
public class ErrController {
    @ExceptionHandler(Throwable.class)
    @ResponseBody
    public String handleExceptions(Throwable e) {
        log.info("============{}",e.getMessage());
       return "{"code":1,"data":null,"bizMsg":"error-123","bizCode":20000}";
    }
}

③重启工程
