1.Struts2的全局属性
我们在使用Struts2进行开发的时候，发现其比Struts1.x要简便得多，其中的部分缘由是Struts2已经帮我们定义了许多以前需要程序员自己去配置的属性，下面我们就来详细的了解这些属性，以及如何修改这些属性以符合具体开发的要求。
2.Struts2的全局属性文件的位置
我们在使用Struts2进行开发的时候，有五个jar包是必须的，分别是：
commons-logging.jar
freemarker.jar
ognl.jar
struts2-core.jar
xwork.jar
其中在struts-core.jar这个包的org.apache.struts2包下有个default.properties的属性文件这就是struts2的全局属性文件。
3.全局属性详解
#使用指定的Configuration来配置struts2，Configuration可以继承自org.apache.struts2.config.Configuration来构建用户自定义的struts的配置参数
struts.configuration=org.apache.struts2.config.DefaultConfiguration
# 设置缺省的地区代码
struts.locale=en_US
#设置Struts2国际化的字符编码
struts.i18n.encoding=UTF-8
# 设置对象工厂，如果指定的话，那么缺省的对象工厂将会被覆盖，注意：某些情况下，可以使用简化标记，例如“spring”，大多数情况下都必须指定com.opensymphony.xwork2.ObjectFactory类的子类的完整类名，
# 例如：struts.org.objectFactory = com.opensymphony.xwork2.StrutsObjectFactory
struts.objectFactory = spring
# 当使用SpringObjectFactory时，指定autoWiring逻辑，有效值是：name，type，auto和constructor，其中缺省值是name。
struts.objectFactory.spring.autoWire = name
# 指示struts-spring整合，如果类的实例需要被缓存，这是应当的，除非以后spring发行版使之成为可能
# 设为true吧，如果你不能确定你正在做什么的话，有效的值是：true，false。缺省为true
struts.objectFactory.spring.useClassCache = true
# 如果指定这个值的话，那么缺省的对象类型决定者将被覆盖，注意：某些情况下可以使用简单标记，例如“triger”或者“notiger”，通常应该指定com.opensymphony.xwork2.util.ObjectTypeDeterminer接口的实现类的完整类名。
# 另外缺省时，由com.opensymphony.xwork2.util.DefaultObjectTypeDeterminer来侦测类的类型。
# 使用泛型时，com.opensymphony.xwork2.util.GenericsObjectTypeDeterminer自xwork2后，已经不再推荐使用，它的功能已经被整合到了DefaultObjectTypeDeterminer。
# 如果要禁用tiger的支持，可以将值设为“notiger”。
struts.objectTypeDeterminer = tiger
# 配置处理http的post请求MIME-type为multipart/form-data的解析器，（文件上传时就使用这种）
# 默认使用jakarta，可选值为：cos，pell，jakarta。
struts.multipart.parser=jakarta
# 设置miltipart/form-data的数据临时存储目录，缺省为javax.servlet.context.tempdir
struts.multipart.saveDir= d:/develop/temp
# 设置miltipart/form-data类型数据的单个文件的最大值，缺省为2M。
struts.multipart.maxSize=2097152
# 加载自定义的属性文件，（不要覆盖struts.properties）
struts.custom.properties=application,org/apache/struts2/extension/custom
# 请求的URL与action间该怎么映射，缺省为org.apache.struts2.dispatcher.mapper.DefaultActionMapper
struts.mapper.class=org.apache.struts2.dispatcher.mapper.DefaultActionMapper
# 这个属性由DefaultActionMapper使用，你可以提供一个由逗号分隔的列表，来表示action的扩展名。
# 例如：struts.action.extension = do,action,aspx，缺省为action
struts.action.extension=action
# 由FilterDispatcher使用，如果为true，那么struts将从它的内部jar中提供静态内容的服务
# 如果为false，那么静态内容必须是<context_path>/struts才有效，缺省为true
struts.serve.static=true
# 由FilterDispatcher使用，只有在struts.serve.static=true的情况下，这个值才有效
# 如果为true，则struts将为静态内容输入报头，浏览器将缓存，
#
如果为false，则struts将为静态内容输入报头，浏览器不缓存，
# 缺省为true
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
### 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
### END SNIPPET: complete_file
