스프링 어플리케이션 컨텍스트 설정 :: 2008/05/15 23:03

/Open Source/Spring
스프링 프레임워크의 버전별 어플리케이션 컨텍스트 설정에 대한 간단한 샘플이다.

1. Spring 1.2에서 DTD 기반의 XML 설정을 지원한다.
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
 "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
 <!-- ========================= DATABASE ============================ -->
 <bean id="propertyConfigurer" 
  class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

   <list>
    <value>jdbc.properties</value>
   </list>
  </property>
 </bean>
 <bean id="dataSource" 
  class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
  <property name="driverClassName" value="${jdbc.driverClassName}" />
  <property name="url" value="${jdbc.url}" />
  <property name="username" value="${jdbc.username}" />
  <property name="password" value="${jdbc.password}" />
 </bean>
 <!-- ========================= TRANSACTION ======================== -->

 </bean>
 <!-- ========================= DAO ================================ -->

 <!-- ========================= SERVICE ============================ -->
 <bean id="exampleService" class="net.java2go.service.ExampleServiceImpl">
  <property name="exampleDao" ref="exampleDao" />
 </bean>
</beans>

2. Spring 2.0에서는 DTD 기반 설정뿐만 아니라 XML 스키마 기반의 XML 설정을 통해 보다 쉬운 컨텍스트 설정을 지원한다. 또한 클래스에서 어노테이션을 사용하여 어노테이션 기반의 컨텍스트 설정을 할 수 있다.

3. Spring 2.5에서 더 많은 XML 네임스페이스와 어노테이션이 추가되었다.
