PropertyPlaceholderConfigurer 从 XML 文件读取（Apache Commons 配置）

是否可以配置 Spring PropertyPlaceholderConfigurer 来读取 properties.xml，通过 Apache Commons 配置？

我在帮助下找到了解决方案seanizer https://stackoverflow.com/questions/3163838/propertyplaceholderconfigurer-reads-from-xml-file-apache-commons-configuration/3165604#3165604 and 弹簧模块 https://springmodules.dev.java.net

<!-- Composite configuration -->
<bean id="configuration" class="org.springmodules.commons.configuration.CommonsConfigurationFactoryBean">
    <property name="configurations">
        <list>
            <!-- User specifics -->
            <bean class="org.apache.commons.configuration.XMLConfiguration">
                <constructor-arg type="java.net.URL" value="file:cfg.xml" />
            </bean>
        </list>
    </property>
</bean>

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
    <property name="properties" ref="configuration"/>
</bean>

<bean id="testConfig" class="uvst.cfg.TestConfiguration">
    <property name="domain" value="${some.prop}"></property>
</bean>

测试配置类

public class TestConfiguration {
    private String domain;
    public String getDomain() {
        return domain;
    }
    public void setDomain(String domain) {
        this.domain = domain;
    }
}

jUnit测试类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration( { "/applicationContextTest.xml" })

public class ApacheCommonCfg2Spring extends AbstractJUnit4SpringContextTests {

    private TestConfiguration tcfg;

    @Test
    public void configuration(){
        tcfg  = this.applicationContext.getBean("testConfig", TestConfiguration.class);
        System.out.println(tcfg.getDomain());
    }

}

Springmodule 相当旧，似乎不再维护，但它可以与 Spring 3.0.3 一起使用。
