How to use Composite Source

18-05-2015

Abstract

• The main motto of this PPT is How to use Composite Source in our applications.

Introduction

• In the case of Composite, the embedded building blocks are actually message sources (i.e. inbound connectors) that listen in parallel on different channels for incoming messages. Whenever any of these receivers accepts a message, the Composite scope passes it to the first message processor in the flow, thus triggering that flow.

Example

.mflow• <?xml version="1.0" encoding="UTF-8"?>

• <mule xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:quartz="http://www.mulesoft.org/schema/mule/quartz" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation" xmlns:spring="http://www.springframework.org/schema/beans" version="EE-3.4.0" 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-current.xsd

• Flow of execution:• 1. Trigger the service using URL mentioned

below:• http://localhost:8091/

(Or)• 2. Quartz component automatically triggers

the service for every 1min
