红帽全球峰会347.3. 内容类型格式
可以解析 JSON 消息，将其转换为 Thrift 格式，并使用原生 util 转换程序来重新解析它。要使用这个选项，请将 contentTypeFormat 值设置为 'json'，或调用 thrift with second 参数。如果没有指定默认实例，始终使用原生二进制 Thrift 格式。简单的 JSON 格式为只写(marshal)，并生成适合按脚本语言解析的简单输出格式。示例代码如下所示：
from("direct:marshal")
.unmarshal()
.thrift("org.apache.camel.dataformat.thrift.generated.Work", "json")
.to("mock:reverse");
from("direct:marshal")
.unmarshal()
.thrift("org.apache.camel.dataformat.thrift.generated.Work", "json")
.to("mock:reverse");
