WILDCARD FILTER

Abstract

The main motto of this PPT is How to use Wildcard Filter in our applications.

Introduction

  The Wildcard filter applies a wildcard pattern to the message payload.

Example

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

<mule 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.xsdhttp://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsdhttp://www.mulesoft.org/schema/mule/http http://www.mulesoft.org/schema/mule/http/current/mule-http.xsd"> <flow name="WildcardFilterFlow1" doc:name="WildcardFilterFlow1"> <http:inbound-endpoint exchange-pattern="request-response" host="localhost" port="8092" path="WildcardFilter" doc:name="HTTP"/> <logger message="--Entered into the flow" level="INFO" doc:name="Logger"/> <set-payload value="Hello MuleSoft" doc:name="Set Payload"/> <wildcard-filter pattern="*m*" caseSensitive="false" doc:name="Wildcard"/> <logger message="--Success" level="INFO" doc:name="Logger"/> </flow></mule>
