在我的Spring Boot 3.0.0项目中，我有一个spring-boot-starter-data-redis依赖项。
如果我在redis服务器未启动时启动应用程序，应用程序也会启动，但有一些例外

有没有一种方法可以“捕获”连接异常并“干净地”记录它们，而不需要堆栈跟踪？

spring-boot

可以在@ControllerAdvice类中捕获异常。

@org.springframework.web.bind.annotation.ExceptionHandler(RedisConnectionFailureException.class)
  public ResponseEntity<Void> redisHandleDataAccessException(RedisConnectionFailureException e) {
    log.error("Failed to establish a connection to the Redis database.", e);
    return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
  }
