本文详细解析了在使用Apache RocketMQ时遇到的TopicListSubCommand异常错误，该错误源于AclSigner无法计算请求签名，具体表现为AlgorithmHmacSHA1不可用。文章提供了具体的解决步骤，包括修改tools.sh文件中的JAVA_OPT配置，添加正确的jre/lib/ext路径，确保HmacSHA1算法可用。

解决方法：
修改tools.sh内的JAVA配置,添加jre/lib/ext目录

gedit tools.sh

修改：

将:
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext"
修改成:
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:${JAVA_HOME}/lib/ext:/java/jdk1.8.0_241/jre/lib/ext"

注意:jdk11没有jre目录，需要手动下载
