Spring Environment Construction

1. Import the jar package:

2. configuration file-applicationcontext.xml:

Add Schema constraint, location:spring-framework-3.2.0.release-"docs-" spring-framework-reference-"html-" Xsd-config.html

Re-configure Service

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "Http://www.springframework.org/schema/beans Http://www.springframework.org/schema/bean S/spring-beans.xsd ">    <!--Configure the object ID to be created for service <bean> configuration: The class used to obtain the instance from the Spring container later: The fully qualified class name of the instance to be created -    <BeanID= "Userserviceid"class= "COM.ITHEIMA.A_IOC." Userserviceimpl "></Bean></Beans>

Applicationcontext.xml

Second, it can be configured to load the JDBC properties file, the data source, the spring framework for integrating hibernate factory beans, transaction managers, component scans, introduction of annotation parsers, transaction annotations, and so on. Such as:
