To simulate the HTTP methods PUT and DELETE, since they aren't supported by HTML, the HTTP parameter "_method" will be used.

Or, expressed as a table:

HTTP method URI Class.method parameters

GET	/movie	Movie.index
POST	/movie	Movie.create
PUT	/movie/Thrillers	Movie.update	id="Thrillers"
DELETE	/movie/Thrillers	Movie.destroy	id="Thrillers"
GET	/movie/Thrillers	Movie.show	id="Thrillers"
GET	/movie/Thrillers/edit	Movie.edit	id="Thrillers"
GET	/movie/new	Movie.editNew

 

The following URL's will invoke its methods:

• GET: /movies => method="index"
• GET: /movies/Thrillers => method="show", id="Thrillers"
• GET: /movies/Thrillers;edit => method="edit", id="Thrillers"
• GET: /movies/Thrillers/edit => method="edit", id="Thrillers"
• GET: /movies/new => method="editNew"
• POST: /movies => method="create"
• PUT: /movies/Thrillers => method="update", id="Thrillers"
• DELETE: /movies/Thrillers => method="destroy", id="Thrillers"

This mapper supports the following parameters:

• struts.mapper.idParameterName - If set, this value will be the name of the parameter under which the id is stored. The id will then be removed from the action name. Whether or not the method is specified, the mapper will try to truncate the identifier from the url and store it as a parameter.
• struts.mapper.indexMethodName - The method name to call for a GET request with no id parameter. Defaults to 'index'.
• struts.mapper.getMethodName - The method name to call for a GET request with an id parameter. Defaults to 'show'.
• struts.mapper.postMethodName - The method name to call for a POST request with no id parameter. Defaults to 'create'.
• struts.mapper.putMethodName - The method name to call for a PUT request with an id parameter. Defaults to 'update'.
• struts.mapper.deleteMethodName - The method name to call for a DELETE request with an id parameter. Defaults to 'destroy'.
• struts.mapper.editMethodName - The method name to call for a GET request with an id parameter and the 'edit' view specified. Defaults to 'edit'.
• struts.mapper.newMethodName - The method name to call for a GET request with no id parameter and the 'new' view specified. Defaults to 'editNew'.

In addition to being a REST-style URL mapper, this plugin provides built-in support for multiple content types, switchable through the URL extension. In this way, a single resource can be exposed as multiple content types without any extra work.

For example, by exposing an "orders" resource, clients can immediately access it via:

http://my.company.com/myapp/orders/1
http://my.company.com/myapp/orders/1.xml
http://my.company.com/myapp/orders/1.xhtml
http://my.company.com/myapp/orders/1.json
