如何使用Swagger具有多个Camel Rest DSL定义

Question

我在Spring-boot应用程序中使用Camel 2.16.0与camel-netty4-http，camel-swagger-java和camel-spring-boot。我SpringBootRouter被配置以下列方式：

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")); 
} 

我怎么能有扬鞭多休息的定义？上面的配置给了我下面的例外。但是，如果我删除其他休息定义其余（“/嗨”）然后Swagger工作得很好。

是啊，这是在Apache的骆驼的错误。我已经登录了票：
