Question

当我尝试访问它时，我收到了部署的代码错误H10。我读到这是因为我必须为应用程序设置一个动态端口。我已经尝试过在Heroku的开发中提供的所有配置，但没有幸运。

这是我的pom.xml：

public class AtLeastOnePropertyAttribute : ValidationAttribute, IClientValidatable
    {
        private readonly string[] _properties;
        public AtLeastOnePropertyAttribute(params string[] properties)
        {
            _properties = properties;
        }

        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            if (_properties == null || _properties.Length < 1)
            {
                return null;
            }
            PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(value);

            List<string> props = new List<string>();
            props.Add(properties[0].ToString());
            foreach (var property in _properties)
            {

                validationContext = new ValidationContext(value);

                var propertyInfo = validationContext.ObjectType.GetProperty(property);
                if (propertyInfo == null)
                {
                    return new ValidationResult(string.Format("unknown property {0}", property));
                }

                var propertyValue = propertyInfo.GetValue(validationContext.ObjectInstance, null);
                if (propertyValue is string && !string.IsNullOrEmpty(propertyValue as string))
                {
                    return null;
                }

                if (propertyValue != null)
                {
                    return null;
                }
            }

            return new ValidationResult(FormatErrorMessage(validationContext.DisplayName), props);
        }

        public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
        {
            var rule = new ModelClientValidationRule
            {
                ErrorMessage = ErrorMessage,
                ValidationType = "atleastonerequired"
            };
            rule.ValidationParameters["properties"] = string.Join(",", _properties);

            yield return rule;
        }
    }

这是完整的错误:(更新）

`
server:
   port: 8080

---
  spring:
     profiles: heroku
  server:
    port: ${PORT}
`

我已经配置了Procfile但没有扩展名。

还是一样。

有什么想法吗？

Answer 1

错误日志未完成。访问herokuapp.com并使用您的帐户登录。您将看到完整的日志。在这里分享该日志。您还应该检查Java版本和数据库连接。大多数时候jdbc驱动程序注册是主要原因。

Answer 2

与heroku默认使用的war不同，jar不会侦听Heroku检查可用性的同一端口。

请参阅https://exampledriven.wordpress.com/2016/11/04/spring-boot-heroku-example/

将--server.port=$PORT添加到Procfile的诀窍不对我有效。

但添加 server.port=${PORT:8080} 春天的application.properties被选中并完美运作了！

使用Maven应用程序的Heroku jar部署Spring Boot，代码= H10
