struts2相干配置

struts2相关配置
1.struts2工程的基础包
   struts2-core-2.0.14.jar
   xwork-2.0.7.jar
   freemarker-2.3.8.jar
   ognl-2.6.11.jar
   commons-logging-1.0.4.jar
2.区别于struts1作为servlet加载，struts2是以filter加载的，如：
web.xml

<filter>
     <filter-name>struts2</filter-name>
     <filter-class>org.apache.struts2.dispatcher.FilterDispatcher
     </filter-class>
</filter>
<filter-mapping>
     <filter-name>struts2</filter-name>
     <url-pattern>/*</url-pattern>
</filter-mapping>

3.struts.xml存放于classes根目录，即src根目录下，基本配置如：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
  <constant name="struts.devMode" value="true" />
  <constant name="struts.action.extension" value="action,do">
  </constant>
  <constant name="struts.custom.i18n.resources" value="local.message">
  </constant>
  <package name="demo" extends="struts-default">
    <action name="HelloWorld" class="org.xmh.demo.HelloWorld">
      <interceptor-ref name="timer"></interceptor-ref>
      <result>/hello.jsp</result>
    </action>
  </package>
  <package name="test1" extends="struts-default" namespace="/mystruts">
    <action name="FirstAction" class="org.xmh.demo.FirstAction">
      <result name="positive">/demo/positive.jsp</result>
      <result name="negative">/demo/negative.jsp</result>
    </action>
    <action name="MultiAction" class="org.xmh.demo.MultiAction">
      <result name="success">/demo/multiAction/index.jsp</result>
      <result name="input">/demo/multiAction/index.jsp</result>
    </action>
    <action name="ValidatorAction" class="org.xmh.demo.ValidatorAction">
      <result name="success">/demo/validate/index.jsp</result>
      <result name="input">/demo/validate/index.jsp</result>
    </action>
  </package>
</struts>

4.国际化
首先，在src下建package，取名locale，创建相关语言包如message_zh_CN.properties，message_en_US.properties等；
然后加载，适用于全局，在struts.xml中添加

<constant name="struts.custom.i18n.resources" value="local.message">

最后编辑jsp，如果是局部加载，需要在<s:form>外层加上

<s:i18n name="locale.message">
<body>
  <s:form action="Login" method="POST">
    <s:textfield name="username" label="%{getText('login.name')}"></s:textfield>
    <s:textfield name="password" label="%{getText('login.password')}"></s:textfield>
    <s:submit value="%{getText('login.submit')}"></s:submit>
  </s:form>
</body>

5.验证validator
基本采用框架验证，除非复杂情况需要在Action类中添加validate<Method>方法
取名方式<ActionClassName>-validation.xml或者
<ActionClassName>-<ActionAliasName>-validation.xml
存放于对应Action相同目录，具体配置如：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
    "-//OpenSymphony Group//XWork Validator 1.0//EN"
    "http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd">
<validators>
	<field name="msg">
		<field-validator type="requiredstring">
			<message key="requiredstring" />
		</field-validator>
	</field>
	<field name="age">
		<field-validator type="int">
			<message key="requiredstring" />
		</field-validator>
	</field>
</validators>

6.Action获取session，request，response
第一种非Ioc方式

ActionContext.getContext().getSession();

或者

HttpServletRequest request = ServletActionContext.getRequest();
HttpServletResponse response = ServletActionContext.getResponse();
HttpSession session = request.getSession();

第二种Ioc方式，对应Action类分别实现SessionAware,ServletRequestAware,ServletResponseAware等接口。
