How to use For Each Component

Abstract

• The main motto of this PPT is how to use For Each component in our applications.

Introduction

• The Foreach scope splits a collection into elements and processes them iteratively through the processors embedded in the scope, then returns the original message to the flow.

Example

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

• <mule xmlns:jdbc-ee="http://www.mulesoft.org/schema/mule/ee/jdbc" xmlns:http="http://www.mulesoft.org/schema/mule/http" 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. URL to trigger the service from browserhttp://localhost:8087/foreach 2. Database component connects to the specific database, executes the select query and prints the result (one by one) using for each component

http://localhost:8087/foreach

http://localhost:8087/foreach
