As well as the technologies listed above, Roo can be extended via addons that you can create using Roo itself that generate and maintain the required source code Java code, POM files, etc for any Java technology you like.
For example, there's an addon for adding a Vaadin UI to a Roo-generated app. You should think of changing the roo wiki entry to include this stuff.

You probably might not appreciate the amount of "convention" being applied by Roo behind the scenes unless you have tried putting an app based on various Spring and other "enterprise" components together : Try following up the names of the various tools especially Maven and AspectJ Funnily, the Ruby crowd seems to fawn over such "magic" happening behind the scenes, whereas some Java folks are like " Convention over configuration are for sissy's, arrrh, I like to build my apps one xml file at time " ; I liked Ben Alex's talk where he introduced the thoughts behind Roo.

Remove the implementation of Serializable interfaces from classes and instead annotate the classes with the RooSerializable annotation. Remove getters and setters methods from your Java classes and instead annotate the classes with the RooJavaBean annotation. Registering the service class with Spring's application context. Using Spring Roo you can't create a service class, which is automatically registered with Spring's application context; therefore, if you want your service class to be auto-registered, then annotate it with the Service annotation.
You can use the toStringMethod attribute of the RooToString annotation to specify a custom name for the toString method, as shown here:. In some cases, you may want to restrict properties from being part of the auto-generated toString method. The RooToString annotation provides an excludeFields attribute, which lets you specify an array of attributes that should be excluded from the auto-generated toString method, as shown here:.
The Adding attributes to a Java class recipe explains how you can add attributes to a Java class using roo. The Creating a Java interface recipe explains how you can create a Java interface from the Roo shell.
There are advantages in adding attributes using Roo as opposed to using an IDE, which we will see in this recipe. The following table shows the name and type of attributes that we will add to a Passenger class in the package sample. Roo provides field commands, which you can use to add different types of fields in your Java class, shown as follows:.
Create an Address class, which is an attribute type in the Passenger class, as shown here:. Create a Passenger class, to which we want to add attributes using the field commands, as shown here:. Add firstName and lastName attributes to the Passenger class using field string command, shown as follows:. Add an age attribute to the Passenger class, using the field number command, shown as follows:.
Add an address attribute of type Address to the Passenger class, using the field other command, shown as follows:. Spring Roo provides multiple field commands for adding different types of attributes to the Java class.
For instance, field string is for adding a String type field, field date is for adding a java. Date or java. Calendar type field, field other is for adding a field of custom Java type, and so on. Some of the field commands, like field set and field reference , apply only to JPA entities, and are therefore not applicable to every Java class that you create in your Roo project.
Also, field commands accept certain arguments, which make sense only if the target Java class is a JPA entity.
We will discuss JPA entity specific field commands in Chapter 2. The field string , field other, and field number commands accept the name argument, which identifies the name of the attribute to be added to the Java class. The field other and field number also require the type of the attribute. This was possible because of the presence of RooJavaBean annotation in the Passenger class.
As the given code suggests, it introduces a toString method to the Passenger class, which returns a concatenated String containing the value of each of its attribute. This was possible because the Passenger class was annotated with the RooToString annotation. Spring Roo actively monitors changes to classes that are annotated with Roo annotations, and any change to classes triggers Spring Roo to update the corresponding AspectJ ITD files. The given figure shows that when you start the Spring Roo shell from a directory, it actively monitors the Java classes in the file system that are annotated with Roo annotations for example RooToString , RooJavaBean , and so on.
This recipe showed that if you want Roo to automatically generate a toString method and getter and setter methods for all the attributes, then annotate your class with RooToString and RooJavaBean annotations.
What if I add an attribute when Spring Roo is not running? At this time Roo may even remove an ITD file if it finds that it is no longer required. Spring Roo doesn't provide commands to remove or modify an attribute.
So, if you want to remove or modify an existing attribute of a Java class, you can do so using your IDE. We saw that using RooJavaBean annotation introduces getter and setter methods for all the fields in a class. In some cases, you may want to control the generation of these getter and setter methods.
These attributes specify whether getter and setter methods should be generated by default or not. The Adding fields to persistent entities recipe of Chapter 2 , Persisting Objects Using JPA shows the additional arguments that are available in field commands.
In this recipe, we will see how we can create an interface named FlightServiceIntf. Spring Roo provides the interface command to create a Java interface, as shown here:. The following table describes the arguments that the interface command accepts:.
It is an optional argument, which instructs Spring Roo to allow reserved words in the name of Java interface. Using Spring Roo you can't add constants or declare methods in your Java interface. To add constants or methods, you need to use your IDE. You may have noticed that the rooAnnotations argument is not available for the interface command; therefore, you can safely assume that Spring Roo doesn't generate any code corresponding to a Java interface when you make modifications to it.
In some scenarios, you may want to set the focus of your commands to a particular Java type. For instance, you may want the Roo shell to execute field commands on a particular Java type, so that you don't need to specify the class argument in your field commands. Spring Roo provides a focus command, which lets you change the target of your commands to a different Java type.
The following sequence of steps shows how we can use the focus command to switch from one type to another:. Execute the following focus command to specify that you want to work with the flight-app project. This will change the Roo prompt to reflect the top-level package name of Roo project:. Create FlightDesc class using the class command. This will change the Roo prompt to refer to the FlightDesc type, shown as follows:. Create a Flight class using the class command.
This will change the Roo prompt from FlightDesc type to refer to the newly created Flight type , as shown here:. Use a focus command to switch to the FlightDesc type. This will change the Roo prompt from referring to Flight type to FlightDesc type, as shown here:.
As the currently referred type by Roo prompt is FlightDesc , you don't need to specify the class argument:. The class argument specifies that the target of the command is the Flight class and not the currently referred FlightDesc class:. The class argument of the focus command lets you specify the fully-qualified name of the Java type with which you want to work. The use of the focus command is mainly to simplify writing commands targeting a particular Java type.
If you don't want to use the focus command in a situation, then you can always use the class argument of the command to specify the target Java type of the command. The A dding attributes to a Java class recipe shows how to add attributes to a Java class using Spring Roo.
In some scenarios, you may want to generate complete enterprise application skeleton by feeding a set of Roo commands to Spring Roo from a text file.
To address such scenarios Spring Roo provides the script command, which allows you to execute commands contained in a text file. The convention is to name the script file containing commands with a.
Roo script is nothing but a text file containing Roo commands. The commands are executed in the order they appear in the text file. In this recipe, we look at how we can execute the commands contained in a ch The ch Download the ch To create the application skeleton execute the script command, by specifying the file containing Roo commands, as shown here:. The script command accepts the following arguments:. It is an optional argument that instructs the Roo shell to print the line numbers of the command being executed from the file.
One of the features that you will not find in Spring Roo is to revert the execution of a previous command. For instance, if you added a field using the field command and now you want to rollback the changes it made, then it is not possible. If you have mistakenly executed a Roo command, you can remove it from the log. If a Roo command fails for some reason, it is commented out in the log. So, you don't need to worry about removing commands that failed execution from your log.

RooJavaBean; import org. RooToString; import org. Note In Spring Roo, AspectJ ITDs are responsible for adding fields, methods, and constructors to Java classes and to make them implement interfaces or extend from a superclass.
Note Roo annotations have source-level retention, which means that your application is not dependent on Roo annotations at runtime. Moving existing Spring projects to use Spring Roo. Tip Registering the service class with Spring's application context Using Spring Roo you can't create a service class, which is automatically registered with Spring's application context; therefore, if you want your service class to be auto-registered, then annotate it with the Service annotation.
