Java 在主类中调用驼峰路由终结点
我创建了一个带有端点'direct:getRestFromExternalService'的Camel路由,当我尝试在另一个类的main方法中使用该端点时,我得到了一个异常 在exchange上执行期间发生异常:exchange[ID-WMLI118067-61025-1493883025815-0-2] 及 终结点上没有可用的使用者:终结点[direct://getRestFromExternalService]. 交易所[ID-WMLI118067-61025-149383025815-0-2] 这是路线等级:Java 在主类中调用驼峰路由终结点,java,apache-camel,Java,Apache Camel,我创建了一个带有端点'direct:getRestFromExternalService'的Camel路由,当我尝试在另一个类的main方法中使用该端点时,我得到了一个异常 在exchange上执行期间发生异常:exchange[ID-WMLI118067-61025-1493883025815-0-2] 及 终结点上没有可用的使用者:终结点[direct://getRestFromExternalService]. 交易所[ID-WMLI118067-61025-149383025815-0-
public class MyRoute extends RouteBuilder {
@Override
public void configure() throws Exception {
// Create the camel context for the REST API routing in Fuse
CamelContext contextFuseAPI = new DefaultCamelContext();
// Start the route inside the context to listen to the ActiveMQ
contextFuseAPI.addRoutes(new RouteBuilder() {
@Override
public void configure() {
from("direct:getRestFromExternalService")
.setHeader(Exchange.HTTP_METHOD, simple("GET"))
.to("<external API URI>");
}
});
}
}
我在没有ProducerTemplate和Object行的情况下测试了main方法,并运行了它。有没有一种方法可以使用另一个类中实现的路由的端点调用requestBody?我解决了这个问题,问题是在route类和main method类中都创建了上下文
public class FuseApp {
public static void main(String[] args) throws Exception {
CamelContext contextFuseAPI = new DefaultCamelContext();
contextFuseAPI.addRoutes(new MyRoute());
contextFuseAPI.start();
Thread.sleep(3000);
ProducerTemplate template = contextFuseAPI.createProducerTemplate();
Object result = template.requestBody("direct:getRestFromExternalService", null, String.class);
Exchange exchange = new DefaultExchange(contextFuseAPI);
String response = ExchangeHelper.convertToType(exchange, String.class, result);
System.out.println("Response : "+ response);
contextFuseAPI.stop();
}
}
