bean-компонент zipkin2.reporter.Sender не найден при использовании Zipkin с kafka в docker

0 голосов
/ 22 апреля 2020

Я работаю над микро сервисом, где микро сервисы общаются друг с другом. Я использую Zipkin с Sleuth и Apache Kafka в качестве брокера сообщений и запускаю микро-сервис и kafka с использованием docker -compose.

Я использую Spring Boot (2.2.6.RELEASE), Spring Cloud ( Hoxton.SR3), изображение Кафки (wurstmeister / kafka: 2.12-2.4.1) и последнее изображение Зипкина.

Когда я пытаюсь раскрутить контейнер, микро-сервис выдает ошибку ниже:

Приложение не удалось запустить

Описание:

Параметру 2 репортера метода в org.springframework.cloud.sleuth.zipkin2.ZipkinAutoConfiguration> требуется компонент типа 'zipkin2.reporter. Отправитель ', который не может быть найден.

Description:

Parameter 2 of method reporter in org.springframework.cloud.sleuth.zipkin2.ZipkinAutoConfiguration required a bean of type 'zipkin2.reporter.Sender' that could not be found.

The following candidates were found but could not be injected:

- Bean method 'rabbitSender' in 'ZipkinRabbitSenderConfiguration' not loaded because @ConditionalOnProperty (spring.zipkin.sender.type=rabbit) found different value in property 'spring.zipkin.sender.type'

- Bean method 'restTemplateSender' in 'ZipkinRestTemplateSenderConfiguration' not loaded because ZipkinSender org.springframework.cloud.sleuth.zipkin2.sender.ZipkinRestTemplateSenderConfiguration kafka sender type

Action:

Consider revisiting the entries above or defining a bean of type 'zipkin2.reporter.Sender' in your configuration.

Причиной ошибки было то, что я забыл добавить зависимость kafka в pom. xml После добавления зависимости ошибка исчезла.
