@Configuration@ConditionalOnClass(DruidDataSource.class)@ConditionalOnProperty(name = \"spring.datasource.type\" havingValue = https://mparticle.uc.cn/"com.alibaba.druid.pool.DruidDataSource\" matchIfMissing = true)
public class DataSourceConfig { @Bean
@ConfigurationProperties(\"spring.datasource.druid\")
public DataSource dataSourceOne() { return DruidDataSourceBuilder.create().build();
