recommended to combine SPRING-JDBC to operate, write dynamic native SQL is easier to develop.Life cycle of JPA objects:New: Instantaneous object, no ID yet, and object associated with persistence context.Managed: Persisted managed object, with ID value, has already established an associated object with persistence context.Datached: A free-form offline object with an ID value, but no associated object with persistence context.Removed: deleted object w

For software systems, persisting data to a database is a critical part. In the Java world, there are many tools and frameworks (ORM) that implement the data persistence layer. In Java applications, the nature of ORM framework is to simplify the operation of the database in the programming of the tedious, such as can be generated by the SQL hibernate, Hibernate also implemented the JPA specification, using J

this separation makes them easier to customize.1.3, MyBatisMyBatis is an open source project for Apache Ibatis, which was migrated to Google code by the Apache Software Foundation in 2010 and renamed MyBatis. MyBatis is a Java-based persistence layer framework. The persistence layer framework provided by Ibatis includes SQL maps and Data Access Objects (DAO) MyBatis eliminates the manual setting of almost all JDBC code and parameters and the retrieval of result sets. MyBatis uses simple XML or

Spring is an IOC and AOP container for lightweight (size and system expense perspectives). It tries to simplify the development of Java EE, that is, Java EE without EJB. And as a core pillar of helping enterprise development, spring is the model layer (or persistence layer: Hibernate, JDO,　Ibatis and other service tiers (EJB, JNDI, WebService), and the presentati

Before we talk about spring transaction management, let's think about how we do data manipulation in hibernate when we're not using spring. In Hibernate we do one operation at a time we have to open the transaction, then the data operation, and then commit the transaction, close the transaction, we do this because
