168.6. 带有 Blueprint XML 的示例

在蓝图 XML 中，您需要配置 JasyptPropertiesParser，它如下所示。然后，会告知 Camel Properties 组件使用 jasypt 作为属性解析器，这意味着 Jasypt 有机会解密值在属性中查找。

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0"
           xsi:schemaLocation="
           http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">

  <cm:property-placeholder id="myblue" persistent-id="mypersistent">
      <!-- list some properties for this test -->
      <cm:default-properties>
          <cm:property name="cool.result" value="mock:{{cool.password}}"/>
          <cm:property name="cool.password" value="ENC(bsW9uV37gQ0QHFu7KO03Ww==)"/>
      </cm:default-properties>
  </cm:property-placeholder>

    <!-- 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>

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

</blueprint>

Properties 组件也可以在 < camelContext> 标签中内联，如下所示。注意我们如何使用 propertiesParserRef 属性来引用 Jasypt。

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0"
           xsi:schemaLocation="
           http://www.osgi.org/xmlns/blueprint/v1.0.0 http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd">

    <!-- 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>

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

</blueprint>
