我正在为要在正文中的 DTO 接受的简单帖子定义以下端点。似乎仅在使用 un/marshall 语句时才有效。许多示例不使用 un/marshal 语句。
休息端点：
rest://post:saveIDto?inType=ContainerDefinitionDto.class&outType=ContainerDefinitionDto.class&type=ContainerDefinitionDto.class
*路线 - 直接失败：processRoute
.from("rest://post:saveIDto?inType=ContainerDefinitionDto.class&outType=ContainerDefinitionDto.class&type=ContainerDefinitionDto.class")
// need to insert below to work
//.unmarshal(new JacksonDataFormat(ContainerDefinitionDto.class))
.log("${body}")
.to("direct:processRoute")
// need to insert below to work
//.marshal(new JacksonDataFormat(ContainerDefinitionDto.class));");
错误：
