springframework + commons-configuration + jasypt 사용 예

springframework와 연동하여 사용하는 예

프로퍼티 관련하여서는 org.springframework.beans.factory.config.PropertyPlaceholderConfigurer 클래스를 사용한다. (설명 및 사용 예는 생략)

jasypt를 이용하여 암호화된 내용을 처리할 때는 EncryptablePropertyPlaceholderConfigurer 클래스를 사용한다.

(org.jasypt.spring3.properties.EncryptablePropertyPlaceholderConfigurer or org.jasypt.spring31.properties.EncryptablePropertyPlaceholderConfigurer)

- commons-configuration  maven dependency 추가

<dependency>

<groupId>commons-configuration</groupId>

<artifactId>commons-configuration</artifactId>

<version>1.10</version>

<exclusions>

<exclusion>

<artifactId>commons-logging</artifactId>

<groupId>commons-logging</groupId>

</exclusion>

</exclusions>

</dependency>

- xml 기반 config 사용

<bean id="xpathExpressEngine" class="org.apache.commons.configuration.tree.xpath.XPathExpressionEngine" />

- 리로링 전략 적용

<bean id="configReloadStrategy" class="org.apache.commons.configuration.reloading.FileChangedReloadingStrategy" />

1. org.springmodules.commons.configuration.CommonsConfigurationFactoryBean 클래스 사용

maven dependency 추가

<dependency>

<groupId>org.springmodules</groupId>

<artifactId>spring-modules-jakarta-commons</artifactId>

<version>0.8</version>

</dependency>

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="properties">

<bean class="org.springmodules.commons.configuration.CommonsConfigurationFactoryBean">

<property name="configurations">

<list>

<ref local="configuration" />

</list>

</property>

</bean>

</property>

</bean>

<bean id="configuration" class="org.apache.commons.configuration.CompositeConfiguration">

<constructor-arg>

<list>

<bean class="org.apache.commons.configuration.PropertiesConfiguration">

<constructor-arg type="java.lang.String">

<value>local_config.properties</value>

</constructor-arg>

</bean>

<bean class="org.apache.commons.configuration.XMLConfiguration">

<constructor-arg type="java.net.URL">

<value>default_config.xml</value>

</constructor-arg>

<property name="reloadingStrategy" ref="configReloadStrategy" />

<property name="expressionEngine" ref="xpathExpressEngine" />

</bean>

</list>

</constructor-arg>

</bean>

2. org.apache.commons.configuration.ConfigurationConverter 클래스 사용

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

<property name="properties">

<bean class="org.apache.commons.configuration.ConfigurationConverter" factory-method="getProperties">

<constructor-arg>

                <bean class="org.apache.commons.configuration.CompositeConfiguration">

<constructor-arg>

<list>

<bean class="org.apache.commons.configuration.PropertiesConfiguration">

                            <constructor-arg type="java.lang.String">

                                <value>local_config.properties</value>

                            </constructor-arg>

                        </bean>

                        <bean class="org.apache.commons.configuration.XMLConfiguration">

                            <constructor-arg type="java.lang.String">

                                <value>default_config.xml</value>

                            </constructor-arg>

<property name="reloadingStrategy" ref="configReloadStrategy" />

<property name="expressionEngine" ref="xpathExpressEngine" />

                        </bean>

</list>

</constructor-arg>

                       </bean>              

</constructor-arg>

</bean>

</property>

</bean>

- XMLConfiguration 혹은 PropertiesConfiguration을 동시에 거의 사용하지는 않을 것같다. (상황에 맞게 선택하면 될듯)
