379.4. 在 Spring DSL 中使用 YAML
在 Spring DSL 中使用数据格式时,您需要首先声明数据格式。这是在 DataFormats XML 标签中进行的。
<dataFormats>
<!--
here we define a YAML data format with the id snake and that it should use
the TestPojo as the class type when doing unmarshal. The unmarshalTypeName
is optional
-->
<yaml
id="snake"
library="SnakeYAML"
unmarshalTypeName="org.apache.camel.component.yaml.model.TestPojo"/>
<!--
here we define a YAML data format with the id snake-safe which restricts the
classes to be loaded from YAML to TestPojo and those belonging to package
com.mycompany
-->
<yaml id="snake-safe">
<typeFilter value="org.apache.camel.component.yaml.model.TestPojo"/>
<typeFilter value="com.mycompany\..*" type="regexp"/>
</yaml>
</dataFormats>然后您可以引用路由中的 id:
<route>
<from uri="direct:unmarshal"/>
<unmarshal>
<custom ref="snake"/>
</unmarshal>
<to uri="mock:unmarshal"/>
</route>
<route>
<from uri="direct:unmarshal-safe"/>
<unmarshal>
<custom ref="snake-safe"/>
</unmarshal>
<to uri="mock:unmarshal-safe"/>
</route>
