How to get a JSON object from a file and map it to a Java class using Apache Camel routes?

Question

我创建了一个扩展RouteBuilder的 RequestRoute ：

@Component
public class RequestRoute extends RouteBuilder {

@Override
public void configure() throws Exception {
    from("file:input?noop=true").to(User.class);
}

在主要的 class 中，我已将上面创建的路线添加到 Camel 上下文中：

  @SpringBootApplication
  public class DemoApplication {

  @SneakyThrows
  public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);

    CamelContext context = new DefaultCamelContext();
    context.addRoutes(new RequestRoute());
  }

}

如何从文件夹内的文件中获取JSON object并使用Camel路线将其转换为 Class？

你需要做一个解组。

from("file:input?noop=true")
.unmarshal().json(JsonLibrary.Jackson, User.class)
