Examples of org.apache.struts2.config.BeanSelectionProvider

org.apache.struts2.components.ComponentUrlProvider

Selects the implementations of key framework extension points, using the loaded property constants. The implementations are selected from the container builder using the name defined in its associated property. The default implementation name will always be "struts".

The following is a list of the allowed extension points:

Type	Property	Scope	Description
com.opensymphony.xwork2.ObjectFactory	struts.objectFactory	singleton	Creates actions, results, and interceptors
com.opensymphony.xwork2.ActionProxyFactory	struts.actionProxyFactory	singleton	Creates the ActionProxy
com.opensymphony.xwork2.util.ObjectTypeDeterminer	struts.objectTypeDeterminer	singleton	Determines what the key and element class of a Map or Collection should be
org.apache.struts2.dispatcher.mapper.ActionMapper	struts.mapper.class	singleton	Determines the ActionMapping from a request and a URI from an ActionMapping
org.apache.struts2.dispatcher.multipart.MultiPartRequest	struts.multipart.parser	per request	Parses a multipart request (file upload)
org.apache.struts2.views.freemarker.FreemarkerManager	struts.freemarker.manager.classname	singleton	Loads and processes Freemarker templates
org.apache.struts2.views.velocity.VelocityManager	struts.velocity.manager.classname	singleton	Loads and processes Velocity templates
com.opensymphony.xwork2.validator.ActionValidatorManager	struts.actionValidatorManager	singleton	Main interface for validation managers (regular and annotation based). Handles both the loading of configuration and the actual validation (since 2.1)
com.opensymphony.xwork2.util.ValueStackFactory	struts.valueStackFactory	singleton	Creates value stacks (since 2.1)
com.opensymphony.xwork2.reflection.ReflectionProvider	struts.reflectionProvider	singleton	Provides reflection services, key place to plug in a custom expression language (since 2.1)
com.opensymphony.xwork2.reflection.ReflectionContextFactory	struts.reflectionContextFactory	singleton	Creates reflection context maps used for reflection and expression language operations (since 2.1)
com.opensymphony.xwork2.config.PackageProvider	N/A	singleton	All beans registered as PackageProvider implementations will be automatically included in configuration building (since 2.1)
com.opensymphony.xwork2.util.PatternMatcher	struts.patternMatcher	singleton	Matches patterns, such as action names, generally used in configuration (since 2.1)
org.apache.struts2.views.dispatcher.DefaultStaticContentLoader	struts.staticContentLoader	singleton	Loads static resources (since 2.1)
com.opensymphony.xwork2.conversion.impl.XWorkConverter	struts.xworkConverter	singleton	Handles conversion logic and allows to load custom converters per class or per action
com.opensymphony.xwork2.TextProvider	struts.xworkTextProvider	default	Allows provide custom TextProvider for whole application
org.apache.struts2.components.UrlRenderer	struts.urlRenderer	singleton	Allows provide custom implementation of environment specific URL rendering/creating class
com.opensymphony.xwork2.UnknownHandlerManager	struts.unknownHandlerManager	singleton	Implementation of this interface allows handle logic of unknown Actions, Methods or Results
org.apache.struts2.views.util.UrlHelper	struts.view.urlHelper	singleton	Helper class used with URLRenderer to provide exact logic for building URLs
com.opensymphony.xwork2.FileManager	struts.fileManager	singleton	Used to access files on the File System as also to monitor if reload is needed, can be implemented / overwritten to meet specific an application server needs

Implementations are selected using the value of its associated property. That property is used to determine the implementation by:

Trying to find an existing bean by that name in the container
Trying to find a class by that name, then creating a new bean factory for it
Creating a new delegation bean factory that delegates to the configured ObjectFactory at runtime

Finally, this class overrides certain properties if dev mode is enabled:

struts.i18n.reload = true
struts.configuration.xml.reload = true

    assert (body != null);


    try {
      writer.write(body);
    } catch (IOException e) {
      throw new StrutsException("IOError while writing the body: " + e.getMessage(), e);
    }
    if (popComponentStack) {
      popComponentStack();
    }
    return false;
