Spring - XML과 Bean을 이용해 .properties 값 가져오기

Spring - XML을 이용해 .properties 값 가져오기

1. xml파일이 있는 경로에 .properties 파일을 만든다.

2.해당 값들의 경로를 지정후 가져온다.

※context같은 네임 스페이스 간단히 추가 방법 : https://cloud0477.tistory.com/62

//context추가 필요 xmlns:context="http://www.springframework.org/schema/context" //스키마Loaction 추가 필요 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"> <context:property-placeholder location="classpath:admin.properties, classpath:sub_admin.properties" /> // .properties경로 <bean id="adminConnection" class="com.javalec.ex.AdminConnection" > <property name="adminId"> <value>${admin.id}</value> //${}를 이용해서 admin.properties 값을 가져온다. </property> <property name="adminPw"> <value>${admin.pw}</value> //${}를 이용해서 admin.properties 값을 가져온다. </property> <property name="sub_adminId"> <value>${sub_admin.id}</value> //${}를 이용해서 sub_admin.properties 값을 가져온다. </property> <property name="sub_adminPw"> <value>${sub_admin.pw}</value> //${}를 이용해서 sub_admin.properties 값을 가져온다. </property> </bean>

cs

3. main.java 에서 값을 가져온다.

        ctx.close();
