Thus, the conclusions provide a comprehensive overview of the performances of Java applications accessing databases depending on the suite decisions considering the database type, the framework in use, and the type of operation, with clear comparisons between the alternatives, the key findings...
特点:根据不同的底层数据库采用不同的主键生成方式。由于Hibernate会根据底层数据库采用不同的映射方式,因此便于程序移植,项目中如果用到多个数据库时,可以使用这种方式。 配置: View Code UUID(常用在网络环境,但是耗费存储空间) UUID使用128位UUID算法生成主键,能够保证网络环境下的主键唯一性,也就能够保证在不同数据...
