Container Managed Persistence(CMP) over Anything ( CMP / A ) extends the CMP entity to support any back-end system that supports create, retrieve, update, and delete methods. 支持任何系统的容器管理持久性(CMP)(ContainerManagedPersistenceoverAnything,CMP/A)扩展了CMP实体以支持任何可以支持创建、检索、更新和删除方法的后端系统。
Approach : The Object-Relational-Mapping-based container managed persistence does not clutter the application code with the relational nature of storage. 方法:基于对象关系映射的容器管理持久化使应用程序代码不会与存储的关系性质混合在一起。
If referential integrity violations are discovered during the load test, then you might also need to set the sequence grouping for container managed persistence. 如果在负载测试过程中发现存在引用完整性违规,则可能还需要为容器管理的持久性设置顺序分组。
With Container Managed Persistence(CMP) ( CMP ) entity beans, the container generates the persistence code as well as managing the persistence logic. 使用容器管理的持久性(ContainerManagedPersistence,CMP)实体bean时,容器生成持久性代码并管理持久性逻辑。
The embedded transaction container requires that a specific data source, TxnDataSource, is used when connecting to the database for Container Managed Persistence(CMP) ( CMP ). 在连接ContainerManagedPersistence(CMP)的数据库时,嵌入式事务容器要求使用一个特定的数据源TxnDataSource。
