<p>The framework uses a number of properties that can be changed to fit your needs. To change any of these properties, 
specify the property key and value in an <code class="language-plaintext highlighter-rouge">default.properties</code> file. The properties file can be locate anywhere 
on the classpath, but it is typically found under <code class="language-plaintext highlighter-rouge">/WEB-INF/classes</code>.</p>

<p>The list of properties can be found in <code class="language-plaintext highlighter-rouge">default.properties</code> (inside <code class="language-plaintext highlighter-rouge">struts2-core.jar</code>).</p>

### START SNIPPET: complete_file

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

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

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

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

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

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

### By default SpringObjectFactory doesn't support AOP
### This flag was added just temporally to check if nothing is broken
### See https://issues.apache.org/jira/browse/WW-4110
struts.objectFactory.spring.enableAopSupport = false

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

### 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-stream
struts.multipart.parser=jakarta
### Uses javax.servlet.context.tempdir by default
struts.multipart.saveDir=
struts.multipart.maxSize=2097152
struts.multipart.maxFiles=256
struts.multipart.maxStringLength=4096
# struts.multipart.maxFileSize=

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

### How request URLs are mapped to and from actions
### Vy default 'struts' name is used which maps to DefaultActionMapper
# struts.mapper.class=restful

### Used by the DefaultActionMapper
### You may provide a comma separated list, e.g. struts.action.extension=action,jnlp,do
### The blank extension allows you to match directory listings as well as pure action names
### without interfering with static resources, which can be specified as an empty string
### prior to a comma e.g. struts.action.extension=, or struts.action.extension=x,y,z,,
struts.action.extension=action,,

### Used by Dispatcher
### If true then Struts serves static content from inside its jar.
### If false then the static content must be available at &lt;context_path&gt;/static
struts.serve.static=true

### A path from which a static content is served, it must start with "/"
### and it cannot end with "/"
struts.ui.staticContentPath=/static

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

### Set this to false if you wish to disable implicit dynamic method invocation
### via the URL request. This includes URLs like foo!bar.action, as well as params
### like method:bar (but not action:foo).
### An alternative to implicit dynamic method invocation is to use wildcard
### mappings, such as &lt;action name="*/*" method="{2}" class="actions.{1}"&gt;
struts.enable.DynamicMethodInvocation = false

### 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
### &lt;action name="*/*" method="{2}" class="actions.{1}"&gt; to match "/foo/edit" or
### "/foo/save".
struts.enable.SlashesInActionNames = false

### Disables support for action: prefix
struts.mapper.action.prefix.enabled = false

### Blocks access to actions in other namespace than current with action: prefix
struts.mapper.action.prefix.crossNamespaces = false

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

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

### Standard UI theme
### Change this to reflect which path should be used for JSP control tag templates by default
struts.ui.theme=xhtml
struts.ui.templateDir=template
### Change this to use a different token to indicate template theme expansion
struts.ui.theme.expansion.token=~~~
### Sets the default template type. Either ftl, vm, or jsp
struts.ui.templateSuffix=ftl

### Sets a global flag which will escape html body of Anchor, Submit and Component tag
### You can control this flag per tag, e.g.: &lt;s:a ... escapeHtmlTag="true"&gt;...&lt;/s:a&gt;
### and this take precedence over the global flag
# struts.ui.escapeHtmlBody=true

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

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

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

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

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

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

### Control whether to search the default resource bundes for messages first (if true) or not (if false).
### Default is false (when not set).
# struts.i18n.search.defaultbundles.first=false

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

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

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

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

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

### maxStrongSize for MruCacheStorage for freemarker, when set to 0 SoftCacheStorage which performs better in heavy loaded application
### check WW-3766 for more details
struts.freemarker.mru.max.strong.size=0

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

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

### Whether to fallback to empty namespace when request namespace does not match any in configuration
struts.actionConfig.fallbackToEmptyNamespace=true

### Whether to allow static field access in OGNL expressions or not
struts.ognl.allowStaticFieldAccess=true

### Whether to throw a RuntimeException when a property is not found
### in an expression, or when the expression evaluation fails
struts.el.throwExceptionOnFailure=false

### Logs as Warnings properties that are not found (very verbose)
struts.ognl.logMissingProperties=false

### Specify the OGNL expression cache factory and BeanInfo cache factory to use.
### Currently, the default implementations are used, but can be replaced with custom ones if desired.
# struts.ognl.expressionCacheFactory=customOgnlExpressionCacheFactory
# struts.ognl.beanInfoCacheFactory=customOgnlBeanInfoCacheFactory

### Specifies the type of cache to use for parsed OGNL expressions. See StrutsConstants class for further information.
struts.ognl.expressionCacheType=wtlfu

### Specifies the maximum cache size for parsed OGNL expressions. This should be configured based on the cache type
### chosen and application-specific needs.
struts.ognl.expressionCacheMaxSize=10000

### Specifies the type of cache to use for BeanInfo objects. See StrutsConstants class for further information.
struts.ognl.beanInfoCacheType=wtlfu

### Specifies the maximum cache size for BeanInfo objects. This should be configured based on the cache type chosen and
### application-specific needs.
struts.ognl.beanInfoCacheMaxSize=10000

### Indicates if Dispatcher should handle unexpected exceptions by calling sendError()
### or simply rethrow it as a ServletException to allow future processing by other frameworks like Spring Security
struts.handle.exception=true

### Applies maximum length allowed on OGNL expressions for security enhancement (optional)
###
### **WARNING**: If developers change this option (by configuration) they should make sure that they understand
###   the implications of setting 'struts.ognl.expressionMaxLength'. They must choose a value large enough to permit
###   ALL valid OGNL expressions used within the application. Values larger than the 200-400 range have diminishing
###   security value (at which point it is really only a "style guard" for long OGNL expressions in an application.
###   Setting a value of null or "" will also disable the feature.
struts.ognl.expressionMaxLength=256

### Defines which named instance of DateFormatter to use, there are two instances:
### - simpleDateFormatter (based on SimpleDateFormat)
### - dateTimeFormatter (based on Java 8 Date/Time API)
### These formatters are using a slightly different patterns, please check JavaDocs of both and more details is in WW-5016
struts.date.formatter=dateTimeFormatter

### Defines which instance of QueryStringBuilder to use, Struts provides just one instance:
### - strutsQueryStringBuilder
### The builder is used by UrlHelp to create a proper Query String out of provided parameters map
struts.url.queryStringBuilder=strutsQueryStringBuilder

### Defines which instance of QueryStringParser to use, Struts provides just one instance:
### - strutsQueryStringParser
### The parser is used to parse Query String into a map
struts.url.queryStringParser=strutsQueryStringParser

### Defines which instances of encoder and decoder to use, Struts provides one default implementation for each
struts.url.encoder=strutsUrlEncoder
struts.url.decoder=strutsUrlDecoder
