Create a Dynamic Web Project in Eclipse. Let's say the name of the project is rabbitmq. Download amqp-client-<version>.jar and javax.jms-api-<version>.jar and add the JAR files to your build path in Eclipse.
In the left panel of Eclipse, at the name of your project (rabbitmq in this example) > Java Resources > src, create a new package. For the sake of this tutorial, let's name the package com.rabbitmq.demo.
In the package, create a class called declare.
In declare.java, add the following markup. In this example, foo.exchange will be created.
package com.rabbitmq.demo;
import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;
import java.net.URISyntaxException;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.util.Date;
import java.text.*;
public class declare {
public void amqDeclare() throws KeyManagementException, NoSuchAlgorithmException, URISyntaxException {
ConnectionFactory cf = new ConnectionFactory();
// use amqp if the server is not using SSL (e.g. http)
cf.setUri("amqp://john.doe:itsasecret@server1.example.com:5671/foo");
// use amqps if the server is using SSL (e.g. https)
cf.setUri("amqps://john.doe:itsasecret@server1.example.com:5671/foo");
Connection conn = null;
try {
System.out.println("Trying to connect to " + conn);
conn = cf.newConnection();
if (conn != null) {
System.out.println("Successfully connected to " + conn);
}
else {
System.out.println("Failed to connect to " + conn);
}
Channel channel = conn.createChannel();
channel.exchangeDeclare("foo.exchange", "topic", true);
}
catch (Exception e) {
e.printStackTrace();
}
finally {
try {
conn.close();
}
catch (Exception e) {
e.printStackTrace();
}
finally {
System.out.println("Successfully closed the connection to " + conn);
}
}
}
}
In the left panel of Eclipse, right click on the name of your project (rabbitmq in this example) and select New > JSP File. Select the WebContent folder, give the file a name such as index.jsp, and select Finish.
Add the following to line 1 of the JSP file. This is the combination of the package (com.rabbitmq.main) and the class (declare.java).
<%@page import="com.rabbitmq.main.declare"%>
Add the following inside the <body> tags.
- In this example, "declare" must be used because the name of the class in declare.java is consumer.
- In this example, "amqDeclare" must be used because the name of the method in declare.java is amqDeclare.
<body>
<%
declare jms = new declare();
jms.amqDeclare();
%>
</body>
Select the green play button in Eclipse and foo.exchange should be created.
Likewise, the main RabbitMQ log file should have something like this.
accepting AMQP connection <0.7993.1338> (10.17.115.16:54343 -> 10.122.15.2:5672)
connection <0.7993.1338> (10.17.115.16:54343 -> 10.122.15.2:5672): user 'john.doe' authenticated and granted access to vhost 'foo'
closing AMQP connection <0.21250.1339> (10.17.115.16:54343 -> 10.122.15.2:5672, vhost: 'foo', user: 'john.doe')
