357.8. HTTP/2 예
이 샘플에서는 HTTP/2 프로토콜을 지원하고 HTTP 서비스를 공개하도록 camel-undertow 구성 요소를 구성합니다. http://localhost:7766/foo/bar.
이 샘플의 디렉터리 구조는 다음과 같습니다.
├── pom.xml 1 ├── README.md └── src └── main └── resources └── META-INF └── spring └── camel-context.xml 2
다음 파일은 HTTP/2 프로토콜을 지원하도록 camel-undertow 구성 요소를 구성하는 데 중요합니다.
- 1
- POM.xml: 다음과 같은 속성 및 종속성을 포함합니다.
<properties> <camel.version>2.23.1</camel.version> </properties> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-core</artifactId> <version>${camel.version}</version> </dependency> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-spring</artifactId> <version>${camel.version}</version> </dependency> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-undertow</artifactId> <version>${camel.version}</version> </dependency> <dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-http-common</artifactId> <version>${camel.version}</version> </dependency> <plugin> <groupId>org.apache.camel</groupId> <artifactId>camel-maven-plugin</artifactId> <version>${camel.version}</version> <configuration> <fileApplicationContextUri>src/main/resources/META-INF/spring/camel-context.xml</fileApplicationContextUri> </configuration> </plugin> - 2
- Camel-context.xml: camel-undertow 구성 요소를 다음과 같이 구성합니다.
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://camel.apache.org/schema/spring http://camel.apache.org/schema/spring/camel-spring.xsd"> <camelContext id="cbr-example-context" xmlns="http://camel.apache.org/schema/spring"> <route id="cbr-route" trace="true"> <from id="_from1" uri="undertow:http://localhost:7766/foo/bar"/> <setBody id="_setBody1"> <constant>Sending Response</constant> </setBody> <log id="_log5" message="Headers ${in.headers}"/> <log id="_log5" message="Done processing ${body}"/> </route> </camelContext> <bean class="org.apache.camel.component.undertow.UndertowComponent" id="undertow"> <property name="hostOptions" ref="undertowHostOptions"/> </bean> <bean class="org.apache.camel.component.undertow.UndertowHostOptions" id="undertowHostOptions"> <property name="http2Enabled" value="true"/> </bean> </beans>
참고
기본적으로 false 로 설정된 http2Enabled 속성은 UndertowHostOptions 클래스에 대해 true 로 설정됩니다. 그런 다음 이 클래스는 camel 경로에 사용되는 UndertowComponent 라고 합니다.
이 예제에서는 pom.xml 파일에서 camel-maven-plugin 을 사용하여 Maven 명령 camel:run 을 실행할 때 HTTP 서비스를 http://localhost:7766/foo/bar 노출할 수 있습니다.
다음과 같이 curl 명령을 사용하여 이 예제를 테스트할 수 있습니다.
