首先是服务端：下载自信版本的seata-server，我下载的是0.9版本，下载后修改2个文件

客户端：
配置文件
spring:
application:
name: test-server
cloud:
alibaba:
seata:
tx-service-group: gzm 需要与服务端一致
consul:
host: localhost
port: 8500
enabled: true
discovery:
enabled: true
service-name: test-server
prefer-ip-address: true
heartbeat:
enabled: true
instance-id: xxxx
pom文件
<!--seata-->
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-alibaba-seata</artifactId>
<version>2.1.0.RELEASE</version>
<exclusions>
<exclusion>
<artifactId>seata-all</artifactId>
<groupId>io.seata</groupId>
</exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>io.seata</groupId>
<artifactId>seata-all</artifactId>
<version>${seata.version}</version>
</dependency>
然后导入服务端的配置file.conf和registry.conf即可。
数据库修正：
把seata-server中自带的Sql执行下，同时需要在每个应用的数据库中同样加入undo_log。
以上就是seata在consul中的使用。
PS:seata客户端中任一应用重启都需要将关联的应用一并重启，不然会报i.s.c.r.netty.NettyClientChannelManager : no available server to connect.的错误。
