Seata分布式事务Caused by: java.lang.IllegalArgumentException：_caused by: java.lang.illegalargumentexception: app-优快云博客

博客内容描述了在Spring Boot应用中使用Seata进行分布式事务处理时遇到的BeanCreationException，具体为IllegalArgumentException，错误信息指出applicationId为空，txServiceGroup为my_test_tx_group。错误堆栈跟踪显示问题发生在'globalTransactionScanner' bean的初始化过程中。解决方案是在application.yml配置文件中，确保spring.application.name属性已设置，避免分布式事务相关参数为空。
