springboot中controller与service间try/catch的性能问题。

咨询下关于try/catch性能，及使用的问题。

背景：个人在service中处理业务时(比如字段校验)习惯使用

throw new RuntimeException("xxx内容不能为空")

这样我可以从controller中使用try/catch中使用

try {
    boolean result = service.result();
    if(result){
        return CommonResponse.success();
    } else {
        return CommonResponse.error(errorCode, errorMsg);
    }
} catch (RuntimeException e) {
    return CommonResponse.error(errorCode, e.getMessage());
}

的方式返回给前端数据(commonResponse是一个公共返回)。

请问这样对性能的影响大吗？可以这样写吗？和直接return service.result()相比那种比较好呢？
