How to connect redis and mule esb using spring data redis module

How To Connect Redis and Mule ESB Using Spring Data Redis
Module
In this article I am going to show you to connect Redis key-value data store and Mule ESB using
Spring Data Redis Module.
Pre-requisite
 Anypoint Studio 6 or above
 Mule ESB 3.8 or above
 Redis 3.2 - https://github.com/MSOpenTech/redis/releases/download/win-3.2.100/Redis-
x64-3.2.100.msi
 Apache Maven 3.3.9 - http://mirror.fibergrid.in/apache/maven/maven-
3/3.3.9/binaries/apache-maven-3.3.9-bin.zip
 Spring Data Redis 1.7.3
 Jedis 2.9.0 – Java driver for Redis.
Use Case
Let’s take a use case where the end user is provided with a user registration HTML form. The
submitted user registration details are then transformed into a POJO and subsequently stored in
REDIS data store. Apart from storing object in Redis, the use case deals with query and delete
operations as well. The scope of this use case is limited to Redis Hash operations only.
Solution
1. Create a Maven based Mule project with Anypoint Studio. In the article it was named
integrating_with_redis.
2. Add the following dependencies in pom.xml:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>1.7.3.RELEASE</version>
</dependency>

<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.9.0</version>
</dependency>

<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
Note: The above dependencies must be added at the top of the
dependency list to avoid version conflict with regards to Spring
framework.
3. Define Global Elements for Spring Redis Configuration and HTTP Listener.

a. JedisConnectionFactory – is required to create and configure
JedisConnectionFactory by which we should be able to connect to Redis.
<spring:bean id="jedisConnectionFactory"
name="jedisConnectionFactory"
class="org.springframework.data.redis.connection.jedis.JedisConnectio
nFactory">
</spring:bean>
b. RedisTemplate – is required to be configured so as to read/write data to and from
Redis.
<spring:bean id="redisTemplate" name="redisTemplate"
class="org.springframework.data.redis.core.RedisTemplate">
<spring:property name="connectionFactory"
ref="jedisConnectionFactory" />
<spring:property name="valueSerializer">
<spring:bean
class="org.springframework.data.redis.serializer.JacksonJsonRedisSeri
alizer">
<spring:constructor-arg
type="java.lang.Class"
value="java.lang.Object" />
</spring:bean>
</spring:property>
</spring:bean>
c. HTTP Listener – is required to be configured for listening to HTTP requests.
<http:listener-config name="HTTP_Listener_Configuration"
host="0.0.0.0" port="8081" doc:name="HTTP Listener
Configuration" />
4. Define Java classes and interfaces in src/main/java folder
a. Model – com.example.redis.model.User – This is a POJO that maps the user
registration HTML form submitted by the end user.
package com.example.redis.model;
import java.io.Serializable;
@SuppressWarnings("serial")
public class User implements Serializable {
private String fname;
private String lname;
private String email;
private String comments;
public String getFname() {
return fname;
}
public void setFname(String fname) {
this.fname = fname;
}

public String getLname() {
return lname;
}
public void setLname(String lname) {
this.lname = lname;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getComments() {
return comments;
}
public void setComments(String comments) {
this.comments = comments;
}
public User() {
}
}
b. Interface – com.example.redis.repository.IHashRepository<V> – This is
required to expose the CRUD operations with regards to Redis.
package com.example.redis.repository;
import java.util.List;
public interface IHashRepository<V> {
void put(V obj);
V get(String key);
void delete(String key);
List<V> getAll();
void delete();
}
c. Implementation Class –
com.example.redis.repository.impl.UserRepository – Implements the
Redis hash operations defined by IHashRepository<V> interface.
package com.example.redis.repository.impl;
import com.example.redis.model.User;
import com.example.redis.repository.IHashRepository;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import java.util.*;
public class UserRepository implements IHashRepository<User> {
private static final String OBJECT_KEY = "USER:";
@Autowired
private RedisTemplate<String,Object> redisTemplate;
@Override
public void put(User user) {
redisTemplate.opsForHash().put(OBJECT_KEY,
user.getEmail(), user);
}
@Override
public User get(String key) {
Object user = redisTemplate.opsForHash().get(OBJECT_KEY,
key);
if (user == null)
return null;
return (User)user;
}
@Override
public void delete(String key) {
redisTemplate.opsForHash().delete(OBJECT_KEY,key);
}
@Override
public List<User> getAll() {
List<User> users = new ArrayList<User>();
Map<Object, Object> entries =
redisTemplate.opsForHash().entries(OBJECT_KEY);
if (entries.isEmpty())
return null;
Set<Object> keys = entries.keySet();
Iterator<Object> iterator = keys.iterator();
while (iterator.hasNext()) {
String key = iterator.next().toString();
User user = (User) entries.get(key);
users.add(user);
}
return users;
}
@Override
public void delete() {
redisTemplate.delete(OBJECT_KEY);
}
}

5. Define Global Mule Configuration element for
com.example.redis.repository.impl.UserRepository.
<spring:bean id="userRepo" name="userRepo"
class="com.example.redis.repository.impl.UserRepository"
/>
6. In this step we will be creating mule flows. We need to represent each CRUD operation with
a mule flow.
a. userFormRedisFlow – The purpose of this flow is to provide the user registration HTML form
to the end user when invoked through the URL http://localhost:8081/.
The parse template transformer loads the following static HTML contents into the mule flow. In
this article it was named user-registration-form.html. This file needs to be kept in
src/main/resources folder.
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body style="margin: 30px;">
<form method="post" action="/store" onSubmit="return
validateForm();">

</div>
18px;">

18px;">
<input name="skip_Submit"
value="Subscribe" type="submit" />
</div>
</td>
</tr>
</table>
</form>
<script type="text/javascript">
function validateForm() {
if
(isEmpty(document.getElementById('fname').value.trim())) {
alert('First name is required!');
return false;
}
if
(isEmpty(document.getElementById('lname').value.trim())) {
alert('Last name is required!');
return false;
}
if
(isEmpty(document.getElementById('email').value.trim())) {
alert('Email is required!');
return false;
}
if
(!validateEmail(document.getElementById('email').value.trim()))
{
alert('Email must be a valid email
address!');
return false;
}
return true;
}
function isEmpty(str) {
return (str.length === 0 || !str.trim());
}
function validateEmail(email) {
var re = /^([w-]+(?:.[w-]+)*)@((?:[w-
]+.)*w[w-]{0,66}).([a-z]{2,15}(?:.[a-z]{2})?)$/i;
return isEmpty(email) || re.test(email);
}
</script>

</body>
</html>

</flow>
b. userRegistrationRedisFlow – The purpose of this flow is to process the HTML form data
posted by the end user via http://localhost:8081/ and creates a new user registration object
into Redis data store.

Run and Test the application
In this section we will be testing each flow that represent the respected Redis Hash operation.
1. Start Redis service if not started.
2. Select Mule Application with Maven option from Run As context menu to run the mule
application.
3. Open any browser and type the URL http://localhost:8081/ to obtain the User Registration
HTML form. Fill the details and submit the form.

On submission, the user registration details are processed by userRegistrationRedisFlow flow
and stored in the Redis data store as a POJO. The following acknowledgement is sent back to
the end user after completion of the registration process indicating successful insertion of a
record in Redis data store.
4. Now, let’s query the record which was inserted in the earlier step. Type the URL
http://localhost:8081/find?email=pankaj.yadav@abc.com in the address bar. The query
result is shown in the screen shot below.

5. Now, let’s delete the record. Type the URL
http://localhost:8081/delete?email=pankaj.yadav@abc.com in the address bar. The following
acknowledgement screen must be displayed if the record is deleted successfully.
Now, let’s try to double check whether the record is deleted. This can be done in two ways:
query the deleted record again and execute the delete operation again.
Type the query operation URL http://localhost:8081/find?email=pankaj.yadav@abc.com
again. The following acknowledgement screen indicates the record has been deleted.
Type the delete operation URL http://localhost:8081/delete?email=pankaj.yadav@abc.com
again. The following acknowledgement screen indicates that the record has been deleted.

6. Now, let’s insert few more records into Redis data store and test to retrieve all the records.

Type the URL http://localhost:8081/findAll in the address bar to retrieve all the records from
the Redis data store, as shown below.
7. Now, type the URL http://localhost:8081/deleteAll in the address bar to delete all the
record.

Let’s assure ourselves whether all the records are deleted by retrieving the records by the
URL http://localhost:8081/findAll. The acknowledgement shown in the below screen shot
assures that the records were deleted.
