REST web application with Struts. Rest and Convention plugins. The sample application developed in this tutorial will handle a simple message system, where its possible to read, add and remove messages. So, the basic bean will be defined in the Message class package com. Message. private String id. String text. private String author. Message. public MessageString id, String text, String author. String get. Id. IdString id. this. Last weekend I purchased some marijuana. Not from some friend of a friend of a friend, but from an actual dispensary in Boulder, Colorado. Boulder, like the rest of. JAR file is a package containing Java application. You could execute it with Java Runtime, but you likely dont want that. Since Minecraft is Java application by.

The message will be identified by the id property and will contain its text and its author in the other two class properties. The next step is to setup a basic business service that will handle the basic operations on the messages find, save, remove and so on. In a real world application this service would be a singleton that interacts with a database through JDBC or JPA but in this little demo the data model is just a very basic and ugly Map kept in a static property of the Message class. The 3Ditor software is exactly the kind of professional subtitling software for 3D subtitles that Ive mentioned above, it is not something intended for normal home. Array. List. import java. Hash.

In messages it is stored the data and the static initializer of the Message. Service class will populate the data model with three messages. Then, some utility methods are provided find. All to retrieve all the messages, findString id to retrieve a message with a specific id, saveMessage message to add or update a message in the data model and, finally, a remove method to delete a specific message. Until now, this tutorial is not related at all with Struts 2. REST capabilities provided by Struts. The first task is to add to the Web application the.

It is not required the manual wiring usually done in the struts. The property struts. Convention plugin will look for Struts. Actions and Controllers, then with struts. Controller suffix will be automatically mapped. The REST controller thats going to be defined in the next step, will have the name Messages. Controller and will be contained in the package com. Given this configuration, the list of the messages in XML format will be accessible through an HTTP GET method on http localhost 8. Struts. 2 Restmessages. JSON messages list, its enough to call the HTTP GET method on http localhost 8. Struts. 2 Restmessages.

HTTP GET method on http localhost 8. Struts. 2 Restmessages. The result is lt list. Message. lt id 3lt id. Message. lt com. Message. lt id 2lt id. Message. lt com. Message. lt id 1lt id.

HTTP POST method on http localhost 8. Struts. 2 Restmessages. In the poster dialog box, the URL must be http localhost 8. Struts. 2 Restmessages. POST action. In Content to Send its required to insert the XML entity for the new message without specifying its id, because it will be automatically generated by Message. Service. lt com.

Id2 that causes the loading of the existing message with id2 in the model property then, depending on which fields are specified in the XML, those message properties are modified and finally a call to update saves the updated message. In the poster dialog box, the URL must be http localhost 8. Struts. 2 Restmessages2. PUT action. In Content to Send its required to insert the XML entity for the fields to edit the unspecified fields will keep the previous values. Message. lt text updated textlt text. Message Rest HTTP Put. After the POST and PUT calls, the data structure will look like this lt list. Message. lt id 3lt id. Message. lt com. Message. lt id 2lt id. Message. lt com. Message. lt id 1lt id. Message. lt com. Message. lt id 4lt id. Message. lt list In this tutorial all the URLs refer to xml content type, but its possible to use json just changing URLs from messages. I hope this tutorial has given a simple and easy introduction to the REST capabilities of Struts. Please leave your comments and feedback.
