The Data Access/Integration layer consists of the JDBC, ORM, OXM, JMS, and Transaction modules.
The spring-jdbc module provides a JDBC-abstraction layer that removes the need to do tedious JDBC coding and parsing of database-vendor specific error codes.
The spring-tx module supports programmatic and declarative transaction management for classes that implement special interfaces and for all your POJOs (Plain Old Java Objects).
The spring-orm module provides integration layers for popular object-relational mapping APIs, including JPA and Hibernate. Using the spring-orm module you can use these O/R-mapping frameworks in combination with all of the other features Spring offers, such as the simple declarative transaction management feature mentioned previously.
The spring-oxm module provides an abstraction layer that supports Object/XML mapping implementations such as JAXB, Castor, JiBX and XStream.
The spring-jms module (Java Messaging Service) contains features for producing and consuming messages. Since Spring Framework 4.1, it provides integration with the spring-messaging module.
数据访问/集成层由JDBC，ORM，OXM，JMS和Transaction 模块组成。
spring-jdbc模块提供了一个JDBC抽象层，消除了对繁琐的JDBC编码和解析数据库供应商特定的错误代码的需要。
spring-tx模块支持实现特殊接口的类以及所有POJO（普通Java对象）的编程和声明事务管理。
spring-orm模块为流行的对象关系映射API提供集成层，包括JPA和Hibernate。使用spring-orm模块，您可以使用这些O / R映射框架结合Spring提供的所有其他功能，例如前面提到的简单声明式事务管理功能。
spring-oxm模块提供了一个支持对象/ XML映射实现的抽象层，例如JAXB，Castor，JiBX和XStream。
spring-jms模块（Java消息服务）包含用于生成和使用消息的功能。从Spring Framework 4.1开始，它提供了与spring-messaging模块的集成。
