Camel - Rest Component 集成 Swagger UI

本文主要是介绍Camel - Rest Component 集成 Swagger UI，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

1. Spring boot 集成 Swagger UI

1.1 pom配置

本示例通过webjar的方式集成swagger UI。
swagger-ui版本为2.2.10.

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>2.3.5.RELEASE</version>
</dependency>
<dependency><groupId>org.webjars</groupId><artifactId>swagger-ui</artifactId><version>2.2.10</version>
</dependency>
<dependency><groupId>org.webjars</groupId><artifactId>webjars-locator</artifactId><version>0.40</version>
</dependency>

配置spring boot 默认启动 tomcat 服务器，启动端口配置为 8088

server.port=8088

1.2 访问swagger ui

http://localhost:8088/webjars/swagger-ui/index.html#/

2. Camel配置并启用Rest服务

2.1 pom配置

<!-- camel -->
<dependency><groupId>org.apache.camel.springboot</groupId><artifactId>camel-spring-boot-starter</artifactId><version>3.6.0</version>
</dependency>
<dependency><groupId>org.apache.camel.springboot</groupId><artifactId>camel-jetty-starter</artifactId><version>3.6.0</version>
</dependency>
<dependency><groupId>org.apache.camel</groupId><artifactId>camel-swagger-java</artifactId><version>3.6.0</version>
</dependency>

2.2 配置并启动jetty服务

配置jetty服务，端口为8080，同时支持 swagger api 服务。
代码参考 https://github.com/ttyy1112/Camel-In-Action-3.3.0/tree/master/spring-app/rest-camel-springboot-test

public class OrderRoute extends RouteBuilder {@Overridepublic void configure() throws Exception {restConfiguration().component("jetty").port(8080)//Enable swagger endpoint..apiContextPath("/swagger") //swagger endpoint path.apiContextRouteId("swagger") //id of route providing the swagger endpoint//Swagger properties.contextPath("/api") //base.path swagger property; use the mapping path set for CamelServlet.apiProperty("api.title", "Swagger UI with Apache Camel-Jetty").apiProperty("api.version", "1.0").apiProperty("api.contact.name", "ATang").apiProperty("api.contact.email", "ATang@atang.com").apiProperty("api.contact.url", "https://atang.com/").apiProperty("host", "") //by default 0.0.0.0.apiProperty("port", "8080").apiProperty("schemes", "").apiProperty("cors", "true");// rest services under the orders context-pathrest("/orders")// need to specify the POJO types the binding is using (otherwise json binding defaults to Map based).get("{id}").outType(Order.class).to("bean:orderService?method=getOrder(${header.id})")// need to specify the POJO types the binding is using (otherwise json binding defaults to Map based).post().type(Order.class).to("bean:orderService?method=createOrder")// need to specify the POJO types the binding is using (otherwise json binding defaults to Map based).put().type(Order.class).to("bean:orderService?method=updateOrder").delete("{id}").to("bean:orderService?method=cancelOrder(${header.id})");}
}

2.3 启动并获取swagger api信息

通过访问 http://localhost:8080/api/swagger ，可以获取swagger api信息。
