是否有可能通过 Apache Commons 配置将 Spring PropertyPlaceholderConfigurer 配置为从 properties.xml 中读取?

我在seanizerspringmodule的帮助下找到了解决方案

<!-- 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>

类测试配置

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 相当陈旧,似乎不再维护,但它适用于 Spring 3.0.3。

随意复制和粘贴!

最简单的方法(虽然可能不是最好的)是继承 PropertyPlaceholdeConfigurer,在那里加载公共配置,然后将其传递给超类:

public class TestPlaceholderConfigurer extends PropertyPlaceholderConfigurer
{
    public TestPlaceholderConfigurer()
    {
        super();
    }

    @Override
    protected void processProperties(ConfigurableListableBeanFactory beanFactoryToProcess, Properties props)
            throws BeansException
    {
        XMLConfiguration config = new XMLConfiguration("config.xml");
        Properties commonsProperties = config.getProperties("someKey")
        // Or something else with the configuration
        super.processProperties(beanFactoryToProcess, commonsProperties);
    }
}

然后你只需使用这个类作为 placeholderConfig:

<bean id="placeholderConfig"
    class="com.exampl.TestPlaceholderConfigurer ">
    <!-- ... -->
</bean>

这是使用弹簧模块的解决方案。我不知道这是多么最新,但即使不是,您也可以轻松获取代码并使其适用于当前版本。
