167.4. 使用 jsonView 属性和 'JacksonXML'DataFormat 的 include/Exclude 字段
例如,您可以使用此属性而不是:
JacksonXMLDataFormat ageViewFormat = new JacksonXMLDataFormat(TestPojoView.class, Views.Age.class);
from("direct:inPojoAgeView").
  marshal(ageViewFormat);
JacksonXMLDataFormat ageViewFormat = new JacksonXMLDataFormat(TestPojoView.class, Views.Age.class);
from("direct:inPojoAgeView").
  marshal(ageViewFormat);直接指定 Java DSL 中的 JSON 视图,如下所示:
from("direct:inPojoAgeView").
  marshal().jacksonxml(TestPojoView.class, Views.Age.class);
from("direct:inPojoAgeView").
  marshal().jacksonxml(TestPojoView.class, Views.Age.class);在 XML DSL 中相同:
<from uri="direct:inPojoAgeView"/>
  <marshal>
    <jacksonxml unmarshalTypeName="org.apache.camel.component.jacksonxml.TestPojoView" jsonView="org.apache.camel.component.jacksonxml.Views$Age"/>
  </marshal>
<from uri="direct:inPojoAgeView"/>
  <marshal>
    <jacksonxml unmarshalTypeName="org.apache.camel.component.jacksonxml.TestPojoView" jsonView="org.apache.camel.component.jacksonxml.Views$Age"/>
  </marshal>
