48.5. Spring XML 示例

在 Spring XML 中，您需要配置 JasyptPropertiesParser，它如下所示。然后，Camel Properties 组件被告知使用 jasypt 作为属性解析程序，这意味着 Jasypt 具有解密值的机会。

<!-- define the jasypt properties parser with the given password to be used -->
<bean id="jasypt" class="org.apache.camel.component.jasypt.JasyptPropertiesParser">
    <property name="password" value="secret"/>
</bean>

<!-- define the camel properties component -->
<bean id="properties" class="org.apache.camel.component.properties.PropertiesComponent">
    <!-- the properties file is in the classpath -->
    <property name="location" value="classpath:org/apache/camel/component/jasypt/secret.properties"/>
    <!-- and let it leverage the jasypt parser -->
    <property name="propertiesParser" ref="jasypt"/>
    <!-- end enable nested placeholder -->
    <property name="nestedPlaceholder" value="true"/>
</bean>

Properties 组件也可以内联在 < camelContext&gt; 标签内，如下所示。请注意，我们如何使用 propertiesParserRef 属性来引用 Jasypt。

<!-- define the jasypt properties parser with the given password to be used -->
<bean id="jasypt" class="org.apache.camel.component.jasypt.JasyptPropertiesParser">
    <!-- password is mandatory, you can prefix it with sysenv: or sys: to indicate it should use
         an OS environment or JVM system property value, so you dont have the master password defined here -->
    <property name="password" value="secret"/>
</bean>

<camelContext xmlns="http://camel.apache.org/schema/spring">
    <!-- define the camel properties placeholder, and let it leverage jasypt -->
    <propertyPlaceholder id="properties"
                         location="classpath:org/apache/camel/component/jasypt/myproperties.properties"
                         nestedPlaceholder="true"
                         propertiesParserRef="jasypt"/>
    <route>
        <from uri="direct:start"/>
        <to uri="{{cool.result}}"/>
    </route>
</camelContext>
