Authors Dr. Zakir Laliwala. Abdul Samad. He was part of an enterprise-level, open source portal application implementation for media and publication houses, portal customization projects, and led a team of developers to achieve the client's requirements on time. Azaz Desai. He is responsible for implementing, deploying, integrating, and optimizing services and business processes using ESB and BPM tools.
Main class. This generates a project containing the structure and all required elements including a skeleton connector, images, sample docs file, but no basic tests for your connector. You can customize the icons by replacing the generated ones. Just make sure that they have the same size so that they look good in Studio. You can check a detailed explanation of the relation between connector structure and Studio.
To solve this, DevKit provides a pair of annotations that let you modularize in different classes:.
There are several types of configuration you can use as we will see in this tutorial. When you mark a field with Config, DevKit ensures that you have an initialized object set when the Mule app runs and that requests are made to your connector. Add our client dependency so that we can use it in our connector.
On the Configuration ConnectorConfig add a configurable field for the address where the Cookbook service is hosted:. Add a configurable field in our Configuration component with a default value for the endpoint our client connects to so that users can connect to different sandboxes.
When a method is annotated with one of these annotations, DevKit invokes it during the lifecycle phase that the annotation represents. Change it to reflect the getRecentlyAdded method signature, and there we have our first connector, ready to be tested.
Run the Generate Sources Action. At this point you can install this Connector and try it in Studio if you want. Once you regenerate the sources, the errors will go away as the generated code will be refreshed. When you add an example, use the same name as the name that narrows the example in the file.
Inside of it you have to put an example of the Processor. If you have the Javadoc check enabled, DevKit plugin marks the missing example as an error and provide a quick fix for us to easily add the example.
You will do a very simple app that listens to an HTTP endpoint and when we hit it, it will retrieve the list of recently added elements. Create a mule app and add a simple http listener. If this is your first mule app, take a look at our Hello World Application.
If you hit the url http: Tests Automation documentation. The full testing documentation. The client you are using provides a login call that initializes the token and uses it in subsequent requests. Take into account that the session can expire and cause the connector to make a login request again.
DevKit provides a different set of annotations to keep your code clean and handle the connection in a different class for delegating responsibilities.
To implement ConnectionManagement, you need to move the initialization to ConnectionManagement, instead of using the Start annotation as we did before. ConnectionIdentifier - Return a string value. This will only be used when debugging. If you install this version and try to run the mule app we created before, you will see that it fails with a SAXParseException because we need to add a username and password to our configuration.
Just open the global configuration of your connector and check that there are 2 new fields, username and password. Configure them and you can run the app again. Check the Test Connectivity section.
DevKit Authentication documentation. The Handler feature, is very useful when you want to avoid duplicated code when handling exceptions, and also so that your connector code is cleaner. When handling messages retrieved from the API, if the message is poor and you know how to improve it, you can use this mechanism, to enrich the error provided to the user.
There is no need for users to add custom code in their Mule apps to handle session expiration. DevKit provides a mechanism to do this in a clean way. In our Mule app, you can configure a reconnection strategy so that our Mule app is ready to handle session expirations. DataSense improves the user experience at design time when creating Mule applications by enabling your connector to determine the API of your target resource.
Even though DataSense is optional, its use enables connector users to acquire metadata of the entities in a service. Adding DataSense. In this tutorial, we use a static DataSense model, which means that the entities are fixed and known upfront, and do not change. The fields that this model supports are also fixed. Analyze the entities in Mule Cookbook service.
Look at how our createIngredient operation looks inside Anypoint Studio, and how it interacts with other components. We defined the operation so that it receives an Ingredient, and it returns an Ingredient with the extra fields populated from the server. Check the input metadata to see that the expected output is a POJO, with the expected fields our Ingredient has:.
Drag and drop a Transform Message element either behind or after our connector. The Transform Message element automatically picks the input or output:. Because DevKit auto-generates static metadata, DevKit automatically ensures that your connector knows how to propagate metadata information. The RefOnly annotation is used to tell DevKit that the input can only be specified as a reference due to a DevKit limitations on handling Abstract classes. The full source code of our connector with a create, update, get and delete operation is available here.
To implement DataSense using a MetaDataCategory, you need to separate your implementation in two steps, retrieving the keys and describing the keys. Modify the method annotate with MetaDataRetriever, to retrieve the description. Because we use a static model, we can just create a POJO model:. Annotate our Connector class with the MetaDataScope annotation.
In your get operation you need specify that the affect only applies to the output so we modify it just a little:. Check our new connector looks in Studio. We have a combo after we select the entity type and save it. This automatically refreshes our metadata. In the previous section we covered the scenario when your model is static. There are APIs that provide a way to get entity definitions dynamically. Salesforce, NetSuite are just some examples of these.
In our Connector now we need to add the code to generate the entities from the Map, and return Map in all our operations. Why is this important? To maintain consistency in our API. In our Mule app, we cannot update the metadata and use our connector.
And, as you can see, note that we have a map structure instead of a POJO:. In order to show this feature you are going to add a processor that will call the searchWithQuery operation of the SDK. Specify the package were you want to create it. In this example org. After that you just need to implement the methods required for you to handle the new page request.
You can find the full source code of the CookbookPagingDelegate. Adding Pagination Support. This triggers the DevKit Maven build tool, which generates an update site folder. The files will be copied under the dropins folder located in the same directory as the AnypointStudio executable, and installed without the need of rebooting your AnypointStudio.
To uninstall the connectors you can either use the shortcut from the UI or remove the folder from the dropins directory and reboot your AnypointStudio.
Open a command prompt or terminal and change directory to where the pom. To update your connector you can repeat the steps made for installing it.
After successfully installing your connector, you can start using your connector in a Mule application. You can add breakpoints in the source code of the connector to debug it. If your connector is a Community connector, the source code ships automatically in the installed connector.
If your connector is an Enterprise, you need to manually attach the source code of your JAR. Update Sites are used to organize and export features so they can be installed into Eclipse applications. When the site is built, the included features along with all plug-ins part of those features will be exported into an installable form. The exported plug-ins and features will be put into two folders "plug-ins" and "features".
Two other files, "content. These files, along with "site. To make the update site available to others you must make all these files available in a shared directory or web site.
You can use the Anypoint DevKit plugin to either install the connector on your current Studio, or export it as an update-site for others to use. This generates a project containing the structure and all required elements including a skeleton connector, images, sample docs, and basic tests for your connector.
Your connector initially consists of message processors and user interface elements. Users can configure the UI elements in Anypoint Studio. The DevKit makes it easy to install a connector in Studio. After you install it in Studio, users can search for your connector and drag it into a Mule flow. You can install at any time during coding. You can even install the starting skeleton connector.
Config annotation is deprecated. Users instead should use Config. On this views, consider the Config as the ConnectorConfig. Optional parameters or configurable ones are elements that are not required, and therefore, there is no need for users to specify a value.
You can specify configurable fields inside you Connector Configuration classes, or as parameters of Processor methods inside a Connector. When you want an optional parameter or configurable you can avoid the use of Optional and just use the Default annotation. Another very important use of the Default annotation is when building a connector that has DataSense.
In order to use OAuth in you connector you just need to annotate your strategy with the OAuth2 annotation. If you want to have multiple connection configurations there are two things to take into account:. The connector Config field needs to be declared either as the interface or as the common parent class. Connection Management Config source code. Basically, a Message Source receives or generates new messages to be processed by Mule. The Source annotation marks a method inside a Connector annotated class as callable from a Mule flow and capable of generating Mule events.
Each marked method will have a Message Source generated. The method must receive a SourceCallback as one of its arguments that represents the next message processor in the chain. It does not matter the order in which this parameter appears as long it is present in the method signature. On your flow now just drag and drop the Cookbook Connector, and you will see that is automatically while generate a flow. Transformers convert message payloads to formats expected by their destinations.
Mule ESB provides many standard transformers, which users can configure using elements and attributes in a Mule XML configuration file. Annotating a method with Transformer signals the DevKit to export a method functionality as a transformer. You need to declare Transformers in classes annotated with Module or Connector and you can declare more than one transformer in a single class.
It is possible to declare transformers, message processors, and message sources all in the same class. Transformers can also be used implicitly as long as only one transformer is found to resolve the type. In your mule app create a flow that takes the first item of the list and add an update operation after it. APIs are exposed in several ways. To start using your API, you should set up a few things before you can use it inside your connector.
If you have an SDK all you need to do is to include the Maven dependency for your jar in the pom. If you have a wsdl, the easiest way to build a connector is to create a client using CXF wsdl2java. You can configure the CXF goal in your pom. The full documentation is at the Apache CXF site. If you use the DevKit plugin it generates everything for you to get started, you just need to specify the WSDL location on your computer. For more information, see the Jersey client documentation.
Features in Tutorial In this tutorial you will learn how to create a connector, using the DevKit, that users can interact with in Mule and Anypoint Studio.
