Spring cloud 整合Seata1.5.2+mysql5.7+mybatis

这里就不赘述服务端的配置了，只写客户端

在nacos上面创建事务组

在 nacos 增加配置 Data ID:service.vgroupMapping.default 配置格式：properties 内容default

service.vgroupMapping 前面固定的格式，后面加**.default**。后面这个可以是client端的spring.application.name的value值，但是它们拼接起来要和nacos的添加的配置文件要保持一致

对应客户端的spring.application.name

客户端application.yaml

server:
  port: 2001

spring:
  application:
    name: seata-order-service
  cloud:
    alibaba:
      seata:
        # 这个名称需要和Seata-server中配置的名称相同
        tx-service-group: default
    nacos:
      discovery:
        server-addr: ip:端口
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://ip:3306/seata_order?useUnicode=true&characterEncoding=utf-8&createDatabaseIfNotExist=true&useSSL=false
    username: root
    password: ***


feign:
  hystrix:
    enabled: false

logging:
  level:
    io:
      seata: info

mybatis:
  mapperLocations: classpath:mapper/*.xml

seata: #设置seata的通讯地址 去nacos 找 seata服务端 TC的地址
  tx-service-group: default
  # 服务配置项
  service:
    # 虚拟组和分组的映射
    vgroup-mapping:
      seata-user-group: default
  # 关闭自动代理
  enable-auto-data-source-proxy: true
  #Seata 应用编号，默认为 ${spring.application.name}
  application-id: ${spring.application.name}
  registry:
    type: nacos
    nacos:
      server-addr: ip:端口
      namespace: ""
      group: SEATA_GROUP
      username: nacos
      password: ***
      cluster: default
      application:  seata-server #服务name要和nacos中保持一致 默认就是seata-server

  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
      server-addr:ip:端口
      namespace: 42445642-cff9-40b9-ba32-d9063670e58d
      group: SEATA_GROUP
      username: nacos

主启动

@EnableDiscoveryClient
@EnableFeignClients
@EnableTransactionManagement
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class SeataOrderApplication {
    public static void main(String[] args) {
        SpringApplication.run(SeataOrderApplication.class,args);
    }
}

值得注意的是如果配置了druid数据源的要删掉比如这样

//@Configuration
public class DataSourceProxyConfig {
    @Value("${mybatis.mapperLocations}")
    private String mapperLocations;

//    @Bean
//    @ConfigurationProperties(prefix = "spring.datasource")
//    public DataSource druidDataSource() {
//        return new DruidDataSource();
//    }

//    @Bean
//    public DataSourceProxy dataSourceProxy(DataSource dataSource) {
//        return new DataSourceProxy(dataSource);
//    }
//
//    @Bean
//    public SqlSessionFactory sqlSessionFactoryBean(DataSourceProxy dataSourceProxy) throws Exception {
//        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
//        sqlSessionFactoryBean.setDataSource(dataSourceProxy);
//        sqlSessionFactoryBean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(mapperLocations));
//        sqlSessionFactoryBean.setTransactionFactory(new SpringManagedTransactionFactory());
//        return sqlSessionFactoryBean.getObject();
//    }
}

seata有自己的数据源，所以使用druid会冲突报错
