x7-repo     (sqli,  Spring JdbcTemplate, Distribution Lock, Cache and so on....)
      @EnableX7Repository           @Repository       and { interface FooRepository extends BaseRepository<Foo> }
      @EnableX7Lock                 @Lock             or  
         { DistributionLock.by(key).lock(task) }

   1. @SpringBootApplication(exclude = IdGeneratorAutoConfiguration.class)
   2. 参照x7-id-generator工程， 新建工程，实现自定义的IdGeneratorService, 代码如下:
        public interface MyIdGeneratorService extends IdGeneratorProxy       

   1. A method, coded with io.xream/acku or seata, maybe we can not use:
        @Lock  or 
        { DistributionLock.by(key).lock(task) }
