> @GreekPanda Hi, can you provider a demo project?
@zjcnb Hi, I'm so sorry that I can't provide a demo project which it's
deeply depent on my own company spring cloud frame, I've tried to remove code
from it, but it's a huge tough work. Is there any demos on spring cloud that I
can reference?
By the way, I wrote a configure file in resource directory and customized
data source, it worked.
Here is my configure file:
@SpringBootApplication(exclude = {
DataSourceAutoConfiguration.class,
DataSourceTransactionManagerAutoConfiguration.class,
DruidDataSourceAutoConfigure.class ,
HibernateJpaAutoConfiguration.class})
@EnableDiscoveryClient
@EnableFeignClients
@EnableZhqcSwagger
@EnableZhqcDozer
@EnableZhqcRedis
@MapperScan("com.zhqc.**.dao")
@ComponentScan({"com.zhqc"})
public class ShardingSeataApplication {
public static void main(String[] args) {
SpringApplication.run(ShardingSeataApplication.class, args);
}
@SneakyThrows
@Bean
public DataSource dataSource() {
DataSource dataSource = YamlShardingSphereDataSourceFactory.
createDataSource(ResourceUtils.getFile("D:\\study\\shardingsphere\\demo\\bywl-shardingsphere-seata-demo\\src\\main\\resources\\config-sharding.yaml"));
return dataSource;
}
}
