1. 1. START SNIPPET: complete_file

1. 1. Struts default properties
    ###(can be overridden by a struts.properties file in the root of the classpath)
    ###

1. 1. Specifies the Configuration used to configure Struts
  2. one could extend org.apache.struts2.config.Configuration
  3. to build one's customize way of getting the configurations parameters into Struts
struts.configuration=org.apache.struts2.config.DefaultConfiguration

1. 1. This can be used to set your default locale and encoding scheme
struts.locale=en_US
struts.i18n.encoding=UTF-8

1. 1. if specified, the default object factory can be overridden here
  2. Note: short-hand notation is supported in some cases, such as "spring"
  3. Alternatively, you can provide a com.opensymphony.xwork2.ObjectFactory subclass name here
struts.objectFactory = spring

1. 1. specifies the autoWiring logic when using the SpringObjectFactory.
  2. valid values are: name, type, auto, and constructor (name is the default)
    struts.objectFactory.spring.autoWire = name

1. 1. indicates to the struts-spring integration if Class instances should be cached
  2. this should, until a future Spring release makes it possible, be left as true
  3. unless you know exactly what you are doing!
  4. valid values are: true, false (true is the default)
    struts.objectFactory.spring.useClassCache = true

1. 1. ensures the autowire strategy is always respected.
  2. valid values are: true, false (false is the default)
    struts.objectFactory.spring.autoWire.alwaysRespect = false

1. 1. if specified, the default object type determiner can be overridden here
  2. Note: short-hand notation is supported in some cases, such as "tiger" or "notiger"
  3. Alternatively, you can provide a com.opensymphony.xwork2.util.ObjectTypeDeterminer implementation name here
  4. Note: By default, com.opensymphony.xwork2.util.DefaultObjectTypeDeterminer is used which handles type detection
  5. using generics. com.opensymphony.xwork2.util.GenericsObjectTypeDeterminer was deprecated since XWork 2, it's
  6. functions are integrated in DefaultObjectTypeDeterminer now.
  7. To disable tiger support use the "notiger" property value here.
    #struts.objectTypeDeterminer = tiger
    #struts.objectTypeDeterminer = notiger

1. 1. Parser to handle HTTP POST requests, encoded using the MIME-type multipart/form-data
struts.multipart.parser=cos
struts.multipart.parser=pell
struts.multipart.parser=jakarta
uses javax.servlet.context.tempdir by default
struts.multipart.saveDir=
struts.multipart.maxSize=2097152

1. 1. Load custom property files (does not override struts.properties!)
struts.custom.properties=application,org/apache/struts2/extension/custom

1. 1. How request URLs are mapped to and from actions
    #struts.mapper.class=org.apache.struts2.dispatcher.mapper.DefaultActionMapper

1. 1. Used by the DefaultActionMapper
  2. You may provide a comma separated list, e.g. struts.action.extension=action,jnlp,do
  3. The blank extension allows you to match directory listings as well as pure action names
  4. without interfering with static resources.
    struts.action.extension=action,,

1. 1. Used by FilterDispatcher
  2. If true then Struts serves static content from inside its jar.
  3. If false then the static content must be available at <context_path>/struts
    struts.serve.static=true

1. 1. Used by FilterDispatcher
  2. This is good for development where one wants changes to the static content be
  3. fetch on each request.
  4. NOTE: This will only have effect if struts.serve.static=true
  5. If true -> Struts will write out header for static contents such that they will
  6. be cached by web browsers (using Date, Cache-Content, Pragma, Expires)
  7. headers).
  8. If false -> Struts will write out header for static contents such that they are
  9. NOT to be cached by web browser (using Cache-Content, Pragma, Expires
  10. headers)
    struts.serve.static.browserCache=true

1. 1. Set this to false if you wish to disable implicit dynamic method invocation
  2. via the URL request. This includes URLs like foo!bar.action, as well as params
  3. like method:bar (but not action:foo).
  4. An alternative to implicit dynamic method invocation is to use wildcard
  5. mappings, such as <action name="/" method=" {2}" class="actions.{1}">
    struts.enable.DynamicMethodInvocation = true
    
    ### Set this to true if you wish to allow slashes in your action names. If false,
    ### Actions names cannot have slashes, and will be accessible via any directory
    ### prefix. This is the traditional behavior expected of WebWork applications.
    ### Setting to true is useful when you want to use wildcards and store values
    ### in the URL, to be extracted by wildcard patterns, such as
    ### <action name="/" method="{2}
    " class="actions.
    {1}
    "> to match "/foo/edit" or
  6. "/foo/save".
    struts.enable.SlashesInActionNames = false

1. 1. use alternative syntax that requires %{} in most places
  2. to evaluate expressions for String attributes for tags
    struts.tag.altSyntax=true

1. 1. when set to true, Struts will act much more friendly for developers. This
  2. includes:
  3. - struts.i18n.reload = true
  4. - struts.configuration.xml.reload = true
  5. - raising various debug or ignorable problems to errors
  6. For example: normally a request to foo.action?someUnknownField=true should
  7. be ignored (given that any value can come from the web and it
  8. should not be trusted). However, during development, it may be
  9. useful to know when these errors are happening and be told of
  10. them right away.
    struts.devMode = false

1. 1. when set to true, resource bundles will be reloaded on every request.
  2. this is good during development, but should never be used in production
    struts.i18n.reload=false

1. 1. Standard UI theme
  2. Change this to reflect which path should be used for JSP control tag templates by default
    struts.ui.theme=xhtml
    struts.ui.templateDir=template
    #sets the default template type. Either ftl, vm, or jsp
    struts.ui.templateSuffix=ftl

1. 1. Configuration reloading
  2. This will cause the configuration to reload struts.xml when it is changed
    struts.configuration.xml.reload=false

1. 1. Location of velocity.properties file. defaults to velocity.properties
    struts.velocity.configfile = velocity.properties

1. 1. Comma separated list of VelocityContext classnames to chain to the StrutsVelocityContext
    struts.velocity.contexts =

1. 1. Location of the velocity toolbox
    struts.velocity.toolboxlocation=

1. 1. used to build URLs, such as the UrlTag
    struts.url.http.port = 80
    struts.url.https.port = 443
  2. possible values are: none, get or all
    struts.url.includeParams = none

1. 1. Load custom default resource bundles
struts.custom.i18n.resources=testmessages,testmessages2

1. 1. workaround for some app servers that don't handle HttpServletRequest.getParameterMap()
  2. often used for WebLogic, Orion, and OC4J
    struts.dispatcher.parametersWorkaround = false

1. 1. configure the Freemarker Manager class to be used
  2. Allows user to plug-in customised Freemarker Manager if necessary
  3. MUST extends off org.apache.struts2.views.freemarker.FreemarkerManager
    #struts.freemarker.manager.classname=org.apache.struts2.views.freemarker.FreemarkerManager

1. 1. Enables caching of FreeMarker templates
  2. Has the same effect as copying the templates under WEB_APP/templates
    struts.freemarker.templatesCache=false

1. 1. Enables caching of models on the BeanWrapper
    struts.freemarker.beanwrapperCache=false

1. 1. See the StrutsBeanWrapper javadocs for more information
    struts.freemarker.wrapper.altMap=true

1. 1. maxStrongSize for MruCacheStorage for freemarker
    struts.freemarker.mru.max.strong.size=100

1. 1. configure the XSLTResult class to use stylesheet caching.
  2. Set to true for developers and false for production.
    struts.xslt.nocache=false

1. 1. Whether to always select the namespace to be everything before the last slash or not
    struts.mapper.alwaysSelectFullNamespace=false

1. 1. Whether to allow static method access in OGNL expressions or not
    struts.ognl.allowStaticMethodAccess=false

1. 1. END SNIPPET: complete_file
