Getting Started with Spring (2)--written in front of the first case

1, introduce spring's jar file

Libs/spring-beans-3.2.2.release.jar

Libs/spring-context-3.2.2.release.jar

Libs/spring-context-support-3.2.2.release.jar

Libs/spring-core-3.2.2.release.jar

Libs/spring-expression-3.2.2.release.jar

Need:

Commons-logging-1.1.1.jar

2. Need to add spring's configuration file

The name of the configuration file can be named casually, but it's best to have practical meaning.

For example:

Spring-dao.xml

Spring-service.xml

Spring.xml

3. How spring configuration files introduce beans constraints

---spring-framework-3.2.2.release-dist/spring-framework-3.2.2.release/docs/spring-framework-reference/html/ Index.html

You can copy the original message:

<?xml version= "1.0" encoding= "UTF-8"?>

<beans xmlns= "Http://www.springframework.org/schema/beans"

xmlns:xsi= "Http://www.w3.org/2001/XMLSc hema-instance"

Xsi:schemalocation= "Http://www.springframework.org/schema/beans

Http://www.springfra mework.org/schema/beans/spring-beans.xsd ">

</beans>

4, the following is an instantiation: container

Read the file parameter dynamic parameters, individual parameters, arrays, and wildcard characters below the classes path

ApplicationContext context = new Classpathxmlapplicationcontext (

"Spring.xml");
