由于部分包未支持Seata1.3，所以需要单独指定

环境准备

Nacos

Seata

数据表：https://github.com/seata/seata/blob/1.2.0/script/server/db/mysql.sql
我使用docker-compose，晚点回补充全部文件

  seata-server:
    image: seataio/seata-server:1.3.0
    environment:
      #STORE_MODE: db
      SEATA_CONFIG_NAME: file:/seata-server/config/registry
      SEATA_IP: 10.0.1.103
      #registry.type: nacos
    volumes:
      - "./seata-server/config:/seata-server/config"
    ports:
      - "8091:8091"
  nacos:
    image: nacos/nacos-server:1.2.1
    environment:
      - PREFER_HOST_MODE=hostname
      - MODE=standalone
      - SPRING_DATASOURCE_PLATFORM=mysql
      - MYSQL_SERVICE_HOST=mysql
      - MYSQL_SERVICE_DB_NAME=nacos_v12
      - MYSQL_SERVICE_PORT=3306
      - MYSQL_SERVICE_USER=nacos
      - MYSQL_SERVICE_PASSWORD=nacos
      - NACOS_AUTH_SYSTEM_TYPE=mysql
      - JAVA_OPT=-Dnacos.core.auth.enabled=true -Dnacos.core.auth.system.type=nacos
    volumes:
      - ./nacos/logs:/home/nacos/logs
      - ./nacos/init.d/custom.properties:/home/nacos/init.d/custom.properties
    ports:
      - "8848:8848"
    depends_on:
      - mysql

数据准备

Nacos

1. 创建namespace=test，创建用户username=test，password=test2020，注意授权为读写状态（需要同步Seata-server的配置文件）

   Seata-Server

2. 配置registry.conf ```java registry { type = “nacos”

   nacos { application = “seata-server” serverAddr = “10.0.1.103:8848” namespace = “test” cluster = “default” username = “test” password = “test2020” } file { name = “file:/seata-server/config/file.conf” } }

config { type = “nacos”

nacos { serverAddr = “10.0.1.103:8848” namespace = “test” group = “SEATA_GROUP” username = “test” password = “test2020” }

file { name = “file:/seata-server/config/file.conf” } }

同步配置到Nacos（可以参考官网）

## SpringCloud应用配置
**特别注意：应用中的配置需要和seata-server启动配置registry.conf需要保持一致**<br />bootstrap.properties
```java
spring.application.name=app-api
#
spring.profiles.active=dev
#
spring.cloud.nacos.username=test
spring.cloud.nacos.password=test2020
spring.cloud.nacos.config.server-addr=10.0.1.103:8848
spring.cloud.nacos.discovery.server-addr=10.0.1.103:8848
spring.cloud.nacos.config.file-extension=yml
spring.cloud.nacos.config.group=DEFAULT_GROUP
spring.cloud.nacos.config.namespace=test
spring.cloud.nacos.discovery.namespace=test

在Nacos增加配置
由于指定spring.profiles.active=dev,所以dataId=app-api-dev.yml

seata:
  enabled: true
  application-id: applicationName
  tx-service-group: my_test_tx_group
  enable-auto-data-source-proxy: false   #一定要是false
  service:
    vgroup-mapping:
      my_test_tx_group: default  #key与上面的tx-service-group的值对应
  # config和registry中的信息与register.conf中配置保持一致
  config:
    type: nacos
    nacos:
      serverAddr: 10.0.1.103:8848
      namespace: test
      group: SEATA_GROUP
      username: test
      password: test2020
  registry:
    type: nacos
    nacos: #这里配置的是seata-server的注册信息
      application: seata-server
      serverAddr: 10.0.1.103:8848
      namespace: test
      group: DEFAULT_GROUP
      cluster: default
      username: test
      password: test2020

踩坑

docker未指定IP，导致应用无法连接

docker 指定运行参数 SEATA_IP: 10.0.1.103

配置版本名称变更

1.0.0 版本配置项seata.service.grouplist 在1.1.0 更改为：seata.service.grouplist.default其中 default 代表 seata注册服务名。
seata.service.grouplist.default内容为seata-server服务的地址，例如
10.0.1.103:8091

应用中的配置需要和seata-server启动配置registry.conf需要保持一致
