组件	版本
spring-cloud-alibaba	2021.1
spring-cloud	2020.0.4

Seata	1.3.0

seataBoth the client's configuration and the registry are usedNacos的.
在application.yml中的配置

# 配置seata客户端的信息
seata:
  application-id: lutong-service
  tx-service-group: lutong-tx-group
  config:
    type: nacos   # Missed here
    nacos:
      server-addr: 127.0.0.1:8848
      namespace: 1e170347-d013-4d8d-9f32-7afc6d5afd61
      group: SEATA_GROUP
      username: nacos
      password: nacos

seata.config.typeConfiguration items are missing.Also pay attention to the need forNacos中添加一个配置项：
service.vgroupMapping.lutong-tx-group=default
