Possible uses of the ActionMapper include defining your own, cleaner namespaces, such as URLs like /person/1, which would be similar to a request to /getPerson.action?personID=1 using the DefaultActionMapper. RestfulActionMapper Content pulled from external source. Click http://HOST/ACTION_NAME/PARAM_VALUE1/PARAM_NAME2/PARAM_VALUE2 This is the same as: http://HOST/ACTION_NAME/ACTION_NAME + "Id"/PARAM_VALUE1/PARAM_NAME2/PARAM_VALUE2 Suppose for example we would like to display some articles by id at using the following URL sheme: http://HOST/article/Id Your action just needs a setArticleId() method, and requests such as /article/1, /article/2, etc will all map to that URL pattern. Restful2ActionMapper Content pulled from external source. Click If the method is not specified (via '!' or 'method:' prefix), the method is "guessed" at using ReST-style conventions that examine the URL and the HTTP method. Parameters are extracted from the action name, if parameter name/value pairs are specified using PARAM_NAME/PARAM_VALUE syntax. These two improvements allow a GET request for 'category/action/movie/Swingers' to be mapped to the action name 'movie' with an id of 'Swingers' with an extra parameter named 'category' with a value of 'action'. A single action mapping can then handle all CRUD operations using wildcards, e.g. <action name="movie/*" className="app.MovieAction"> <param name="id">{0}</param> ... </action> The following URL's will invoke its methods: GET: /movie => method="index" GET: /movie/Swingers => method="view", id="Swingers" GET: /movie/Swingers!edit => method="edit", id="Swingers" GET: /movie/new => method="editNew" POST: /movie/Swingers => method="update" PUT: /movie/ => method="create" DELETE: /movie/Swingers => method="remove" To simulate the HTTP methods PUT and DELETE, since they aren't supported by HTML, the HTTP parameter "__http_method" will be used. The syntax and design for this feature was inspired by the ReST support in Ruby on Rails. See http://ryandaigle.com/articles/2006/08/01/whats-new-in-edge-rails-simply-restful-support-and-how-to-use-it CompositeActionMapper Content pulled from external source. Click For example with the following in struts.properties :- struts.mapper.class=org.apache.struts2.dispatcher.mapper.CompositeActionMapper struts.mapper.composite.1=org.apache.struts2.dispatcher.mapper.DefaultActionMapper struts.mapper.composite.2=foo.bar.MyActionMapper struts.mapper.composite.3=foo.bar.MyAnotherActionMapper CompositeActionMapper will be configured with 3 ActionMapper, namely "DefaultActionMapper", "MyActionMapper" and "MyAnotherActionMapper". CompositeActionMapper would consult each of them in order described above. Next: Profiling
