Spring XD 无法找到 RabbitMQ ConnectionFactory 的 class 定义
Spring XD unable to find class definition for RabbitMQ ConnectionFactory
我正在从 xd-singlenode 模式切换到分布式，使用版本 1.3.1-RELEASE。
我在 docker 容器中 运行ning Spring XD，使用 Dockerfile similar to the one here. According to the XD guide，如果我想使用 RabbitMQ 作为我的数据传输，那么我需要配置 servers.yml 文件。我在一个单独的 docker 容器中有 RabbitMQ 运行ning，我 link 这两个容器一起作为 docker 组合的一部分。
简而言之，我已经配置了所有内容（我相信是正确的），但是当我在 Spring XD 中转到 运行 多个流时（这就是 RabbitMQ 发挥作用的时候，因为它会充当容器之间的消息传输）Spring XD 抛出以下异常：

编辑 2：看起来 xd-admin 和 xd-container 脚本 do not add the messagebus jars 到 $CLASSPATH 在 AdminServerApplication 或 [=24= 开始时].我不确定这是否是罪魁祸首。

../../Downloads/spring-xd-1.3.1.RELEASE/xd/lib/messagebus/rabbit/spring-xd-messagebus-rabbit-1.3.1.RELEASE.jar
运行时在解析配置时将该目录添加到类路径中。
xd-admin 和 xd-container do not add any of the messagebus jars to the classpath 的 Spring XD 启动脚本在启动各自的应用程序之前。他们只添加直接位于 /lib 中的罐子和 lib/hadoop27/ 中的 hadoop 罐子。
我能够通过修改脚本以在类路径中包含必要的 jar 来解决此问题：
RABBIT_LIB=$APP_HOME/lib/messagebus/rabbit
if [ -d "$RABBIT_LIB" ]; then
for k in "$RABBIT_LIB"/*.jar; do
CLASSPATH="$CLASSPATH":"$k"
done
fi

运行时在解析配置时将该目录添加到类路径中。
xd-admin 和 xd-container do not add any of the messagebus jars to the classpath 的 Spring XD 启动脚本在启动各自的应用程序之前。他们只添加直接位于 /lib 中的罐子和 lib/hadoop27/ 中的 hadoop 罐子。
我能够通过修改脚本以在类路径中包含必要的 jar 来解决此问题：
RABBIT_LIB=$APP_HOME/lib/messagebus/rabbit
if [ -d "$RABBIT_LIB" ]; then
for k in "$RABBIT_LIB"/*.jar; do
CLASSPATH="$CLASSPATH":"$k"
done
fi
