Struts2中有关struts-default.xml,struts.xml,struts.properties文件详解

1）struts-default.xml

这个文件是struts2框架默认加载的配置文件。它定义struts2一些核心的bean和拦截器。

2）struts.xml

该文件也是struts2框架自动加载的文件，在这个文件中可以定义一些自己的action,interceptor，package等，该文件的package通常继承struts-default包。下面是这个文件的格式。

struts.properties文件

3）default.properties
这个文件是struts2框架的全局属性文件，也是自动加载的文件。该文件包含了系列的key-value对。该文件完全可以配置在struts.xml文件中，使用constant元素。下面是这个文件中一些常见的配置项及说明。

###指定加载struts2配置文件管理器，默认为org.apache.struts2.config.DefaultConfiguration
###开发者可以自定义配置文件管理器，该类要实现Configuration接口，可以自动加载struts2配置文件。
#struts.configuration = org.apache.struts2.config.DefaultConfiguration

###设置默认的locale和字符编码
#struts.locale = en_US
struts.i18n.encoding = UTF- 8


###指定struts的工厂类
#struts.objectFactory = spring

###指定spring框架的装配模式
###装配方式有:name , type , auto , andconstructor(name是默认装配模式)
struts.objectFactory.spring.autoWire = name

###该属性指定整合spring时，是否对bean进行缓存，值为trueorfalse , 默认为true.
struts.objectFactory.spring.useClassCache = true

###指定类型检查
#struts.objectTypeDeterminer = tiger
#struts.objectTypeDeterminer = notiger

###该属性指定处理MIME-typemultipart/form-data，文件上传
#struts.multipart.parser = cos
#struts.multipart.parser = pell
struts.multipart.parser = jakarta
#指定上传文件时的临时目录，默认使用javax.servlet.context.tempdir
struts.multipart.saveDir =
struts.multipart.maxSize = 2097152

###加载自定义属性文件(不要改写struts.properties!)
#struts.custom.properties = application , org/apache/struts2/extension/custom

###指定请求url与action映射器，»˜认为org.apache.struts2.dispatcher.mapper.DefaultActionMapper
#struts.mapper.class = org.apache.struts2.dispatcher.mapper.DefaultActionMapper

###指定action的后缀，默认为action
struts.action.extension = action

###被FilterDispatcher使用
###如果为true则通过jar文件提供静态内容服务.
###如果为false则静态内容必须位于<context_path>/struts
struts.serve.static = true

###被FilterDispatcher使用
###指定浏览器是否缓存静态内容，测试阶段设置为false，发布阶段设置为true.
struts.serve.static.browserCache = true

###设置是否支持动态方法调用，true为支持，false不支持.
struts.enable.DynamicMethodInvocation = true

###设置是否可以在action中使用斜线，默认为false不可以，想使用需设置为true.
struts.enable.SlashesInActionNames = false

###是否允许使用表达式语法，默认为true.
struts.tag.altSyntax = true


###设置当struts.xml文件改动时，是否重新加载.
###-struts.configuration.xml.reload = true
###设置struts是否为开发模式，默认为false , 测试阶段一般设为true.
struts.devMode = false

###设置是否每次请求，都重新加载资源文件，默认值为false.
struts.i18n.reload = false

###标准的UI主题
###默认的UI主题为xhtml , 可以为simple , xhtml或ajax
struts.ui.theme = xhtml
###模板目录
struts.ui.templateDir = template
#设置模板类型.可以为ftl , vm , orjsp
struts.ui.templateSuffix = ftl

###定位velocity.properties文件.默认velocity.properties
struts.velocity.configfile = velocity.properties

###设置velocity的context.
struts.velocity.contexts =

###定位toolbox.
struts.velocity.toolboxlocation =

###指定web应用的端口.
struts.url.http.port = 80
###指定加密端口
struts.url.https.port = 443
###设置生成url时，是否包含参数.值可以为:none , getorall
struts.url.includeParams = get

###设置要加载的国际化资源文件，以逗号分隔.
#struts.custom.i18n.resources = testmessages , testmessages2

###对于一些web应用服务器不能处理HttpServletRequest.getParameterMap()
###像WebLogic , Orion , andOC4J等，须设置成true , 默认为false.
struts.dispatcher.parametersWorkaround = false

###指定freemarker管理器
#struts.freemarker.manager.classname = org.apache.struts2.views.freemarker.FreemarkerManager

###设置是否对freemarker的模板设置缓存
###效果相当于把template拷贝到WEB_APP/templates.
struts.freemarker.templatesCache = false

###通常不需要修改此属性.
struts.freemarker.wrapper.altMap = true

###指定xsltresult是否使用样式表缓存.开发阶段设为true , 发布阶段设为false.
struts.xslt.nocache = false

###设置struts自动加载的文件列表.
struts.configuration.files = struts-default.xml , struts-plugin.xml , struts.xml

###设定是否一直在最后一个slash之前的任何位置选定namespace.
struts.mapper.alwaysSelectFullNamespace = false
