seata和postgresql和springcloud整合

第一步导入坐标

 <dependency>
        <groupId>org.postgresql</groupId>
        <artifactId>postgresql</artifactId>
        <scope>runtime</scope>
    </dependency>

    <!--druid-->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>druid-spring-boot-starter</artifactId>
        <version>1.1.10</version>
    </dependency>

    <!-- mp 依赖 -->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
        <version>3.2.0</version>
    </dependency>


    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-alibaba-seata</artifactId>
        <version>2.2.0.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>io.seata</groupId>
                <artifactId>seata-spring-boot-starter</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>io.seata</groupId>
        <artifactId>seata-spring-boot-starter</artifactId>
        <version>1.3.0</version>
    </dependency>

第二步增加seata配置

seata:
  enabled: true
  application-id: demo
  tx-service-group: my_test_tx_group
  enable-auto-data-source-proxy: true
  config:
    type: nacos
    nacos:
      namespace:
      server-addr: 192.168.101.50:8848
      group: SEATA_GROUP
      username: nacos
      password: nacos
  registry:
    type: nacos
    nacos:
      application: seata-server
      server-addr: 192.168.101.50:8848
      namespace:
      username: nacos
      password: nacos

第三步resources下增加seata.conf文件

client {
    ##这是唯一的和项目名保持一致
    application.id = demo
    transaction.service.group = my_test_tx_group
}
