spring boot多数据库数据源启动报错“required a single bean, but 2 were found”的正确解决办法

报错

Parameter 0 of method jdbcTemplate in org.springframework.boot.autoconfigure.jdbc.JdbcTemplateConfiguration required a single bean, but 2 were found:- primaryDataSource: defined by method 'dataSource' in class path resource [com/xxx/xxx/base/infra/config/PrimaryDataSourceConfig.class]- shardingSphereDataSource: defined by method 'dataSource' in class path resource [com/xxx/xxx/ShardingDataSourceAutoConfiguration.class]

解决方法：
1.启动类加：

@EnableAutoConfiguration(exclude = DataSourceAutoConfiguration.class)

或者

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

2.在其中一个datesource上添加 @Primary注解
