seata1.7.0是采用application.yml方式配置的。

seata的注册加配置中心采用nacos设置，所以需要修改application.yml文件，我将此文件通过cofigmap方式挂载出来了。可直接修改cofigmap，然后重启seata服务生效。nacos的server地址和namespace等根据自己实际情况修改。

configmap.yaml如下：

---
apiVersion: v1
data:
  application.yml: >-
    server:
      port: 7091
    spring:
      application:

    console:

    seata:

          password: nacos

seata的在nacos的配置，需要注意几点：

1.seata客户端要和seata在一个namesapce和group下。

2.seata.properties要在nacos的配置管理中添加。具体内容可去seata的官网上查看。

3.seata客户端的一些配置要和nacos配置的对起来。具体在springboot集成seata中再说。
