struts2中的constant

struts.serve.static.browserCache 该属性设置浏览器是否缓存静态内容。当应用处于开发阶段时，我们希望每次请求都获得服务器的最新响应，则可设置该属性为false。

struts.enable.DynamicMethodInvocation 该属性设置Struts 2是否支持动态方法调用，该属性的默认值是true。如果需要关闭动态方法调用，则可设置该属性为false。

struts.enable.SlashesInActionNames 该属性设置Struts 2是否允许在Action名中使用斜线，该属性的默认值是false。如果开发者希望允许在Action名中使用斜线，则可设置该属性为true。

struts.tag.altSyntax 该属性指定是否允许在Struts 2标签中使用表达式语法，因为通常都需要在标签中使用表达式语法，故此属性应该设置为true，该属性的默认值是true。

struts.devMode该属性设置Struts 2应用是否使用开发模式。如果设置该属性为true，则可以在应用出错时显示更多、更友好的出错提示。该属性只接受true和flase两个值，该属性的默认值是false。通常，应用在开发阶段，将该属性设置为true，当进入产品发布阶段后，则该属性设置为false。

struts.i18n.reload该属性设置是否每次HTTP请求到达时，系统都重新加载资源文件。该属性默认值是false。在开发阶段将该属性设置为true会更有利于开发，但在产品发布阶段应将该属性设置为false。

提示 开发阶段将该属性设置了true，将可以在每次请求时都重新加载国际化资源文件，从而可以让开发者看到实时开发效果；产品发布阶段应该将该属性设置为false，是为了提供响应性能，每次请求都需要重新加载资源文件会大大降低应用的性能。

struts.ui.theme该属性指定视图标签默认的视图主题，该属性的默认值是xhtml。

struts.ui.templateDir该属性指定视图主题所需要模板文件的位置，该属性的默认值是template，即默认加载template路径下的模板文件。

struts.ui.templateSuffix该属性指定模板文件的后缀，该属性的默认属性值是ftl。该属性还允许使用ftl、vm或jsp，分别对应FreeMarker、Velocity和JSP模板。

struts.configuration.xml.reload该属性设置当struts.xml文件改变后，系统是否自动重新加载该文件。该属性的默认值是false。

struts.velocity.configfile该属性指定Velocity框架所需的velocity.properties文件的位置。该属性的默认值为velocity.properties。

struts.velocity.contexts该属性指定Velocity框架的Context位置，如果该框架有多个Context，则多个Context之间以英文逗号（,）隔开。

struts.velocity.toolboxlocation该属性指定Velocity框架的toolbox的位置。

struts.url.http.port该属性指定Web应用所在的监听端口。该属性通常没有太大的用户，只是当Struts 2需要生成URL时（例如Url标签），该属性才提供Web应用的默认端口。

struts.url.https.port该属性类似于struts.url.http.port属性的作用，区别是该属性指定的是Web应用的加密服务端口。

struts.url.includeParams该属性指定Struts 2生成URL时是否包含请求参数。该属性接受none、get和all三个属性值，分别对应于不包含、仅包含GET类型请求参数和包含全部请求参数。

struts.custom.i18n.resources该属性指定Struts 2应用所需要的国际化资源文件，如果有多份国际化资源文件，则多个资源文件的文件名以英文逗号（,）隔开。

struts.dispatcher.parametersWorkaround 对于某些Java EE服务器，不支持HttpServlet Request调用getParameterMap()方法，此时可以设置该属性值为true来解决该问题。该属性的默认值是false。对于WebLogic、Orion和OC4J服务器，通常应该设置该属性为true。

struts.freemarker.manager.classname 该属性指定Struts 2使用的FreeMarker管理器。该属性的默认值是org.apache.struts2.views.freemarker.FreemarkerManager，这是Struts 2内建的FreeMarker管理器。

struts.freemarker.wrapper.altMap该属性只支持true和false两个属性值，默认值是true。通常无需修改该属性值。

struts.xslt.nocache 该属性指定XSLT Result是否使用样式表缓存。当应用处于开发阶段时，该属性通常被设置为true；当应用处于产品使用阶段时，该属性通常被设置为false。

struts.configuration.files 该属性指定Struts 2框架默认加载的配置文件，如果需要指定默认加载多个配置文件，则多个配置文件的文件名之间以英文逗号（,）隔开。该属性的默认值为struts-default.xml,struts-plugin.xml,struts.xml，看到该属性值，读者应该明白为什么Struts 2框架默认加载struts.xml文件了。

Struts2常量列表（struts-default.propertie -->struts2.jar）

### Struts default properties

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

###

 

### Specifies the Configuration used to configure Struts

### one could extend org.apache.struts2.config.Configuration

### to build one's customize way of getting the configurations parameters into Struts

# struts.configuration=org.apache.struts2.config.DefaultConfiguration

 

### 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

 

### 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

# uses javax.servlet.context.tempdir by default

struts.multipart.saveDir=

struts.multipart.maxSize=2097152

 

### 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

#struts.mapper.class=org.apache.struts2.dispatcher.mapper.DefaultActionMapper

 

### Used by the DefaultActionMapper

### You may provide a comma separated list, e.g. struts.action.extension=action,jnlp,do

struts.action.extension=action

 

### Used by FilterDispatcher

### If true then Struts serves static content from inside its jar.

### If false then the static content must be available at <context_path>/struts

struts.serve.static=true

 

### 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 -> 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 -> 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 <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

### "/foo/save".

struts.enable.SlashesInActionNames = false

 

### use alternative syntax that requires %{} in most places

### to evaluate expressions for String attributes for tags

struts.tag.altSyntax=true

 

### 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

#sets the default template type. Either ftl, vm, or jsp

struts.ui.templateSuffix=ftl

 

### 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 = get

 

### Load custom default resource bundles

# struts.custom.i18n.resources=testmessages,testmessages2

 

### 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

 

### configure the XSLTResult class to use stylesheet caching.

### Set to true for developers and false for production.

struts.xslt.nocache=false

 

### A list of configuration files automatically loaded by Struts

struts.configuration.files=struts-default.xml,struts-plugin.xml,struts.xml

 

### Whether to always select the namespace to be everything before the last slash or not

struts.mapper.alwaysSelectFullNamespace=false
