如何使用Swagger实现多个Camel Rest DSL定义

spring-bootjava-8apache-camelswagger

我正在使用Camel 2.16.0与camel-netty4-http、camel-swagger-java和camel-spring-boot在Spring-boot应用程序中。我的SpringBootRouter配置如下：

   public void configure() {

    restConfiguration()
    .component("netty4-http")
    .bindingMode(RestBindingMode.json)
    .dataFormatProperty("prettyPrint", "true")
    .host("0.0.0.0")
    .contextPath("/")
    .port(port)
    .apiContextPath("/api-doc")
         .apiProperty("api.title", "User API")
         .apiProperty("api.version", "1.2.3")
         .apiProperty("cors", "true");

    rest("/hello").description("Say hello.")
    .produces("application/json")
    .get().description("Get hello.").route().transform(constant("hello"));

    rest("/hi").description("Say hi.")
    .produces("application/json")
    .get().description("Get hi.").route().transform(constant("hi"));
}

如何使用Swagger拥有多个rest定义？ 上面的配置只给我了以下异常。然而，如果我删除其他的rest定义 rest("/hi") ，那么Swagger就能正常工作。

可能是camel-spring-boot的问题。你能否将你的示例项目作为ZIP附加到CAMEL jira工单上，以便我们可以从中复现？或者在github上放一个项目之类的东西？ - Claus Ibsen
我已经在Jira工单上发布了，并且这里也附上了Github示例项目的链接：https://github.com/jnupponen/camel-spring-boot-swagger-problem - jnupponen
