Apache Came组件rest的使用

The rest component allows to define REST endpoints using the [Rest DSL][] and plugin to other Camel components as the REST transport.

代码如下：

<camelContext id="camelContext" xmlns="http://camel.apache.org/schema/spring">
    
    	<restConfiguration bindingMode="auto" component="restlet" port="3387" />
    
    	
    	<rest path="/api">
    		
    		<get uri="/products">
    			<to uri="direct:products" />
    		</get>
    
    		
    		<get uri="/product/{id}">
    			<to uri="direct:product" />
    		</get>
    
    		
    		<post uri="/product/create">
    			<to uri="bean:productNew" />
    		</post>
    	</rest>
    
    	<route>
    		<from uri="direct:products" />
    		<setBody>
    			<constant>this is products list</constant>
    		</setBody>
    	</route>
    
    	<route>
    		<from uri="direct:product" />
    		<to uri="log:show1?showAll=true&multiline=true" />
    		<setBody>
    			<simple>this is product ${in.header.id}</simple>
    		</setBody>
    	</route>
    
    	
    	<route>
    		
    		<from uri="rest:get:topics" />
    		<setBody>
    			<constant>this is topic list</constant>
    		</setBody>
    	</route>
    
    	
    	<route>
    		<from uri="rest:get:topic/{id}" />
    		<setBody>
    			<simple>this is topic[id=${in.header.id}]</simple>
    		</setBody>
    	</route>
    
    </camelContext>

最后，加入maven依赖

<dependency>
    	<groupId>org.apache.camel</groupId>
    	<artifactId>camel-restlet</artifactId>
    	<version>2.15.3</version>
    </dependency>
