Apache Сторм: SLF4J: путь Класс содержит несколько привязок SLF4J

Question

Я работаю над топологией образца (один носик ОНТ болт), но Когда я запускаю мой шторм проект с помощью командной строки:

шторма баночка мишень/разъема -0.0.1-ПАНОРАМА-банку-с-dependencies.jar topology.ConnectorTopology

я получаю ошибку

Я пытался много решений, которые я нашел в Интернете, но не результат. есть ли у вас какое-либо представление об источнике проблемы?

Answer 1

Я решил эту проблему, добавив:

<scope>provided</scope> 

и

<exclusions> 
       <exclusion> 
        <groupId>org.slf4j</groupId> 
        <artifactId>log4j-over-slf4j</artifactId> 
       </exclusion> 
       <exclusion> 
        <groupId>org.slf4j</groupId> 
        <artifactId>slf4j-api</artifactId> 
       </exclusion> 
       <exclusion> 
        <groupId>logback-classic</groupId> 
        <artifactId>ch.qos.logback</artifactId> 
       </exclusion> 
      </exclusions> 

Как это:

<dependency> 
      <groupId>org.apache.storm</groupId> 
      <artifactId>storm-core</artifactId> 
      <version>1.0.0</version> 

      <scope>provided</scope> 
      <exclusions> 
       <exclusion> 
        <groupId>org.slf4j</groupId> 
        <artifactId>log4j-over-slf4j</artifactId> 
       </exclusion> 
       <exclusion> 
        <groupId>org.slf4j</groupId> 
        <artifactId>slf4j-api</artifactId> 
       </exclusion> 
       <exclusion> 
        <groupId>logback-classic</groupId> 
        <artifactId>ch.qos.logback</artifactId> 
       </exclusion> 
      </exclusions> 

     </dependency> 

Answer 2

Вы найдете решение здесь: http://www.slf4j.org/codes.html#multiple_bindings

Добавить исключение в зависимости (от pom.xml), которые могут быть вызваны конфликтом.

<exclusions> 
    <exclusion> 
    <groupId>org.slf4j</groupId> 
    <artifactId>slf4j-log4j12</artifactId> 
    <version>1.7.xx</version> 
    </exclusion> 
</exclusions> 

Answer 3

Многократное связывание SLF4J приводит к появлению предупреждающего сообщения, но ваша программа будет продолжать работать. Причина Exception вы видите в вашей трассировке стеки:

Вызванный: java.lang.RuntimeException: java.io.IOException: Найдено несколько defaults.yaml ресурсов. Вероятно, вы собрали банки Storm с вашей флягой с топологией. [jar: файл: /root/cloud/connector/target/connector-0.0.1-SNAPSHOT-jar-with-dependencies.jar! /defaults.yaml, jar: файл:/usr/share/storm/lib/ливневых ядро-1.0.0.jar! /defaults.yaml]

Устраните в вашем банке дубликат defaults.yaml.
