seata 在读取yml 配置时驼峰命令的问题

我的环境是
JDK1.8
SpringBoot-2.1.8.RELEASE
SpringCloud-Greenwich.SR3
seata-server-1.1
seata-spring-boot-starte-1.1
以下是配置文件:
seata:
tx-service-group: my_test_tx_group
enable-auto-data-source-proxy: true
application-id: ${spring.application.name}
config:
type: springCloudConfig
service:
disable-global-transaction: false
vgroup-mapping:
my_test_tx_group: default
grouplist:
default: 127.0.0.1:8091
enable-degrade: false
registry:
type: eureka
eureka:
application: default
service-url: http://localhost:1001/eureka
weight: 1
错误日志为:
no available service 'null' found, please make sure registry config correct
获取的配置参数key：seata.service.vgroup-mapping.my_test_tx_group
实际在yml中的配置为:seata.service.vgroupMapping.my_test_tx_group

Start by tracing how the Seata Spring Boot configuration reads the YAML key seata.service.vgroup-mapping.my_test_tx_group and compare it with the reported bound key seata.service.vgroupMapping.my_test_tx_group. Check the configuration handling around vgroupMapping and reproduce the reported no available service 'null' error with the environment and YAML shown. Done means the configured group resolves to default and the service is found.
