activemq-all 强制我使用 log4j slf4j 实现

Question

我想在我的应用程序中使用 logback slf4j 实现，但是 activemq-all 通过包含 log4j 实现类破坏了类路径。我不是唯一一个面临这个问题的人，例如multiple SLF4J bindings Error with activemq-all-5.6.0.jar 所见证的。根据那篇文章，我必须用

替换 activemq-all

org.apache.activemq:activemq-camel
org.apache.activemq:activemq-core
org.apache.activemq:activemq-console
org.apache.activemq:activemq-jaas
org.apache.activemq:activemq-optional
org.apache.activemq:kahadb
org.apache.geronimo.specs:geronimo-jms_1.1_spec
org.apache.geronimo.specs:geronimo-jta_1.0.1B_spec
org.apache.geronimo.specs:geronimo-j2ee-management_1.1_spec
org.apache.geronimo.specs:geronimo-annotation_1.0_spec.

问题是我没有这些工件的完整 Maven 依赖项（组 ID、工件 ID、版本）。有人可以为我提供一个现成的替代品

        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-all</artifactId>
            <version>5.9.0</version>
        </dependency> 

Answer 1

您可以使用活跃的 mq 核心库。请注意，active mq 向后兼容客户端。

    <dependency>
        <groupId>org.apache.activemq</groupId>
        <artifactId>activemq-core</artifactId>
        <version>5.4.3</version>
          <exclusions>
            <exclusion>                 
              <artifactId>org.slf4j</artifactId>
              <groupId>slf4j-log4j12</groupId>
            </exclusion>
            <exclusion>                 
              <artifactId>log4j</artifactId>
              <groupId>log4j</groupId>
            </exclusion>
        </exclusions>
    </dependency>

简而言之，您已经列出了您找到的工件的组 ID/工件 ID，用冒号分隔。请注意，这些满足 ActiveMQ 5.6 的一些用例。例如 activemq-core 不再有效 - 请改用 activemq-client 和 activemq-broker。

目前，这些工件都捆绑在 activemq-all 中。但是您可能需要查看pom.xml 以了解您选择的版本（此列表可能会随着时间而改变）。除非您打算在应用程序中嵌入具有所有传输、插件和配置的代理，否则您可能不需要所有这些。

<artifactSet>
  <includes>
    <include>${project.groupId}:activemq-client</include>
    <include>${project.groupId}:activemq-openwire-legacy</include>
    <include>${project.groupId}:activemq-camel</include>
    <include>${project.groupId}:activemq-jaas</include>
    <include>${project.groupId}:activemq-broker</include>
    <include>${project.groupId}:activemq-console</include>
    <include>${project.groupId}:activemq-shiro</include>
    <include>${project.groupId}:activemq-spring</include>
    <include>${project.groupId}:activemq-pool</include>
    <include>${project.groupId}:activemq-jms-pool</include>
    <include>${project.groupId}:activemq-amqp</include>
    <include>${project.groupId}:activemq-http</include>

    <include>org.apache.activemq.protobuf:activemq-protobuf</include>
    <include>org.fusesource.hawtbuf:hawtbuf</include>
    <include>org.jasypt:jasypt</include>
    <include>org.apache.geronimo.specs:geronimo-jms_1.1_spec</include>
    <include>org.apache.geronimo.specs:geronimo-jta_1.0.1B_spec</include>
    <include>org.apache.geronimo.specs:geronimo-j2ee-management_1.1_spec</include>
    <include>org.apache.geronimo.specs:geronimo-annotation_1.0_spec</include>
    <include>org.slf4j:slf4j-api</include>
    <include>org.slf4j:slf4j-log4j12</include>
    <include>log4j:log4j</include>
  </includes>
</artifactSet>

好的，org.apache.activemq 的版本号应该只是您要使用的版本。对于 geronimo 规范，这不是很明显。

<dependency>
   <groupId>org.apache.geronimo.specs</groupId>
   <artifactId>geronimo-jms_1.1_spec</artifactId>
   <version>1.1.1</version>
</dependency>

<dependency>
      <groupId>org.apache.geronimo.specs</groupId>
      <artifactId>geronimo-j2ee-management_1.1_spec</artifactId>
      <version>1.0.1</version>
</dependency>

<dependency>
      <groupId>org.apache.geronimo.specs</groupId>
      <artifactId>geronimo-annotation_1.0_spec</artifactId>
      <version>1.1.1</version>
</dependency>

Answer 3

我在使用 activemq-all API 时也遇到了同样的问题，我用下面的依赖替换了这个依赖，它对我有用。

<!-- https://mvnrepository.com/artifact/org.apache.activemq/activemq-spring -->
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-spring</artifactId>
    <version>5.14.3</version>
</dependency>

希望这可以帮助其他人。
