Apache Camel Developer's Cookbook

Chapter 2. Message Routing

In this chapter, we will cover the following recipes:

  • Content Based Routing
  • Filtering out unwanted messages
  • Wire Tap – sending a copy of the message elsewhere
  • Multicast – routing the same message to many endpoints
  • Recipient List – routing a message to a list of endpoints
  • Throttler – restricting the number of messages flowing to an endpoint
  • Request-response route sending a one-way message
  • One-way route waiting on a request-response endpoint
  • Dynamic Routing – making routing decisions at runtime
  • Load balancing across a number of endpoints
  • Routing Slip – routing a message to a fixed list of endpoints

Introduction

This chapter explains how to make use of Camel's built-in EIPs (Enterprise Integration Patterns) to write typical integration logic. Once a message is consumed from an endpoint, you will want to make decisions about what steps should be taken to process it (such as routing), and these EIPs provide you with many different message routing options. The EIPs are used within routes defined by the Camel DSLs (Domain Specific Language).

The EIPs are first class constructs within the DSL. As such, your integration logic will be able to more clearly express how the message is being routed–that is, which EIP is being used. The more you can use these EIP DSL statements within your Camel code, versus doing a lot of routing within custom Java processors, the easier it will be for you and others to understand what the Camel route is doing for future maintenance. This is a key value of Camel, so take full advantage of it within your code, and you will find that you have gained...

Content Based Routing

When you need to route messages based on the content of the message, and/or based on the headers or properties associated with the message, using Camel's Content Based Router EIP is a great way to do that.

Content Based Routing

Content Based Routing and Filtering are very similar. A Content Based Router has multiple predicates, and the contained steps are performed on the first predicate that the message matches, or the optional otherwise statement if none matches (similar to an if () {..} else if () {..} else {..} statement in Java).

Camel's Filter EIP tests against a single predicate, executing the contained processing steps only if the message matches that predicate. The equivalent of a Filter in Java would be a single if statement.

In this recipe, we will see how to use a Content Based Router to route a message to one of the several destinations based on the content (the body) of the message.

Getting ready

The Java code for this recipe is located in the org.camelcookbook.routing...

Filtering out unwanted messages

When you need to perform a sequence of steps only when a message matches a certain condition (Predicate), then a Filter is a good option.

Filtering out unwanted messages

Content Based Routing and Filtering are very similar. Filtering processes a message only if it matches the single predicate provided (much like a single if statement).

A Content Based Router routes a message based on the first of the multiple predicates, or the optional otherwise statement if none of the provided predicates matched (similar to an if () {..} else if () {..} else {..} statement in Java).

This recipe will show you how to perform message processing steps only on those messages that match a specified predicate.

Getting ready

The Java code for this recipe is located in the org.camelcookbook.routing.filtering package. The Spring XML files are located under src/main/resources/META-INF/spring and prefixed with filtering.

How to do it...

Create a filter statement followed by a predicate using any of the Camel Expression...

Wire Tap – sending a copy of the message elsewhere

When you want to process the current message in the background (concurrently) to the main route, without requiring a response, the Wire Tap EIP can help. A typical use case for this is logging the message to a backend system. The main thread of execution will continue to process the message through the current route as usual, while Wire Tap allows additional messaging processing to occur outside of the main route.

Wire Tap – sending a copy of the message elsewhere

This recipe will show you how to send a copy of the message to a different endpoint.

Getting ready

The Java code for this recipe is located in the org.camelcookbook.routing.wiretap package. The Spring XML files are located under src/main/resources/META-INF/spring and prefixed with wireTap.

How to do it...

Use the wireTap statement and specify the endpoint URI of where to send a copy of the message.

In the XML DSL, this is written as follows:

<route>
  <from uri="direct:start"/>
  <wireTap uri="mock...

Multicast – routing the same message to many endpoints

When you want to route the same message to a number of endpoints and have them process the message in different ways, the Multicast EIP is a good choice.

This recipe will show you the default, sequential way to use Camel's Multicast EIP. Chapter 6, Parallel Processing, contains a recipe for using Multicast with concurrency (threads).

Getting ready

The Java code for this recipe is located in the org.camelcookbook.routing.multicast package. The Spring XML files are located under src/main/resources/META-INF/spring and prefixed with multicast.

How to do it...

Use the multicast DSL statement, and list the endpoints and processing steps within it.

In the XML DSL, this routing logic is written as:

<route>
  <from uri="direct:start"/>
  <multicast>
    <to uri="mock:first"/>
    <to uri="mock:second"/>
    <to uri="mock:third"/>
  </multicast>
</route...

Recipient List – routing a message to a list of endpoints

When you want to dynamically (at runtime) decide a list of endpoints that an individual message should be sent to, use the Recipient List EIP. This EIP is made up of two phases: deciding where to route the message, and subsequently invoking those route steps. It can be thought of as a dynamic Multicast, and behaves in much the same way.

Recipient List – routing a message to a list of endpoints

This recipe will show you how to route a message to a number of dynamically specified endpoints.

Getting ready

The Java code for this recipe is located in the org.camelcookbook.routing.recipientlist package. The Spring XML files are located under src/main/resources/META-INF/spring and prefixed with recipientList.

How to do it...

Use the recipientList DSL statement, which includes an Expression that tells it where to get, the list of endpoints for routing the message at runtime.

In the XML DSL, this routing logic is written as:

<route>
  <from uri="direct:start"/>
  <setHeader...

Throttler – restricting the number of messages flowing to an endpoint

When you need to limit the number of messages flowing through a route during a specified time period, the Throttler EIP can help. For example, if you have a downstream system that can only handle 10 requests per second, using a Throttler EIP within your route can ensure that you do not exceed that rate.

This recipe will show you how to restrict the number of messages routed to a set of endpoints during a specified time period.

Getting ready

The Java code for this recipe is located in the org.camelcookbook.routing.throttler package. The Spring XML files are located under src/main/resources/META-INF/spring and prefixed with throttler.

How to do it...

In order to use the Throttler, perform the following steps:

  1. You must specify the maximum number of messages to be allowed per time period (defaults to 1,000 ms).

    In the XML DSL, this is specified as an Expression to allow for the maximum rate to be changed at runtime. In this...

Request-response route sending a one-way message

When processing a message in a Request-Response (InOut) route, you sometimes need to send the message to an endpoint, but do not want to receive a response. This recipe shows you how to invoke such an endpoint using the InOnly MEP.

The MEP used can radically alter the behavior of an endpoint. For example, if you invoke a JMS endpoint within a request-response (InOut) route, it will send a message to a queue and set up a listener on a temporary destination waiting for a response; this is known as request-response over messaging. If the consumer of the message on the other side of the queue has not been written to send a response message, your route will wait indefinitely (or as long as the configurable timeout of the component).

This recipe shows how you can alter the MEP temporarily in order to send messages one way in a request-response route.

Wow! What an amazing book to get started with Apache Camel, I've never used this before and found this book immensely helpful. It was a practical read, very organized, and covered everything I expected to learn. The parallel processing was probably my favorite chapter, with error handling in a close 2nd place. The book was easily understood and well worth the $25, which if you catch a sale or one of the specials makes buying more than one book advantageous.Debugging and Security were on point and I'm always critical about these two areas, you need to find bugs and squash them along with maintaining the integrity of the application even on the security side. Overall I felt the book delivered and was not overdone, just enough to get me started while leaving room for growth which I would get into more advanced books for.Publisher Link: https://www.packtpub.com/application-development/apache-camel-developers-cookbook

tl;dr: buy nowThis book is essential reading for every serious Apache Camel developer. Its return on investment is great even if you only use a single recipe. But you will be able to use many of them. It greatly reduces the learning curve (and head scratching) and you will find a lot of material not covered anywhere else.This book will not gather dust on a shelf (or in the Amazon cloud), you will use it often.

Apache Camel is the de-facto standard java integration library with support for hundreds of components for talking to external systems, implementation of the enterprise integration patterns from the EIP book, all wrapped up in a declarative, expressive DSL. Throw in testing support out of the box, vibrant community, and production support, and you cannot beat it for integration work.Camel in Action is the authoritative book up to this point on understanding and using Apache Camel. This book builds on that foundational knowledge and demonstrates, step-by-step, how to use Camel to solve real world problems. The content is divided into small bite-sized chunks of functionality or recipes that explain how to solve a specific problem in both the XML and Java DSL as well as how it works and things to watch out for.If you just recently learned Camel and are looking for best practices for solving common integration problems, I highly recommend it. It's targeted toward a moderate to advanced leaning set of architects and developers who already have some experience with Camel.

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
