Classnotfoundexception 导致 SimpleMessagelistenerContainer 停止
Classnotfoundexception causes SimpleMessagelistenerContainer stop
我发现当 listener 抛出一个 classnotfoundexception 时，simplemessagelistenercontainer 将停止并且对序列消息不起作用。
我已将 defaultrejectqueue 设置为 false，我是否也应该捕获所有异常并重新抛出 amqprejectrequeueexception？

不清楚你的意思；如果在初始化期间没有找到 class 那么，当然，容器将不会启动。
如果侦听器在正常消息处理期间抛出 ClassNotFoundException，则消息将被拒绝（并根据配置重新排队或不重新排队）；但是容器不会停止。
您需要准确解释您的意思，包括堆栈跟踪（编辑问题 - 不要尝试在评论中添加堆栈跟踪）。

那里没有 class 未找到异常，只有空指针异常：
