Thanks Ravi for your insight,
I did the following, just like to know how I can send the request to two
modules get the result and send it back if the url pattern is in a specific
form.
Currently I am directing traffic based on the REST url pattern, now I want
to send to two or more modules requests and process the request and return
the result if the REST url pattern is in a specific form.
My RouteBuilder is:
public class CustomRouteBuilder extends RouteBuilder {
@Autowired
Processor customProcessor;
@Override
public void configure() throws Exception {
String aUrl = System.getProperty("A_URL");
String bUrl = System.getProperty("B_URL");
from("servlet:///?matchOnUriPrefix=true")
.process(customProcessor)
.recipientList(header("restUrl"));
}
}
My CustomProcessor is:
public void process(Exchange exchange) throws Exception {
String aRestServices = System.getProperty("A_REST_URLS");
String bRestServices = System.getProperty("B_REST_URLS");
String aUrl = System.getProperty("A_URL");
String bUrl = System.getProperty("B_URL");
String cUrl = System.getProperty("C_URL");
String CamelHttpUri = (String)
exchange.getIn().getHeader("CamelHttpUri");
String CamelHttpQuery = (String)
exchange.getIn().getHeader("CamelHttpQuery");
String urlReceived = CamelHttpUri;
if (CamelHttpUri.indexOf("/servicebus/camel") > -1) {
urlReceived = CamelHttpUri.substring(17);
} else {
if (CamelHttpUri.indexOf("/camel") > -1) {
urlReceived = CamelHttpUri.substring(6);
}
}
String urlToMatch = urlReceived;
if (!StringUtils.isEmpty(CamelHttpQuery)) {
urlToMatch = urlToMatch + "?" + CamelHttpQuery;
}
// get aRestServiceEndPointURL if it matches to incoming URL
String endpointUrl = getEndPointUrl(aRestServices, aUrl,
urlToMatch);
if (StringUtils.isEmpty(endpointUrl)) {
endpointUrl = getEndPointUrl(bServices, bUrl,
urlToMatch);
}
if (StringUtils.isEmpty(endpointUrl)) {
endpointUrl = "http4://" + cUrl +
"?bridgeEndpoint=true&throwExceptionOnFailure=false";
}
exchange.getIn().setHeader("CamelHttpUri", urlReceived);
exchange.getIn().setHeader("CamelHttpQuery", CamelHttpQuery);
exchange.getIn().setHeader("restUrl", endpointUrl);
exchange.getOut().setHeaders(exchange.getIn().getHeaders());
exchange.getOut().setBody(exchange.getIn().getBody(String.class),
String.class);
}
private String getEndPointUrl(String restServiceUrls, String restUrl,
String urlToMatch) {
List<String> restServiceUrlList =
Arrays.asList(restServiceUrls.split("\\s*,\\s*"));
for (String restUrlPattern : restServiceUrlList) {
Pattern pattern = Pattern.compile(restUrlPattern);
Matcher matcher = pattern.matcher(urlToMatch);
if (matcher.matches()) {
return "http4://" + restUrl +
"?bridgeEndpoint=true&throwExceptionOnFailure=false";
}
}
return "";
}
