为动作定义静态参数

struts.xml

<struts>

   <constant name="struts.custom.i18n.resources" value="global" />
   <constant name="struts.devmode" value="true" />
	
   <package name="default" namespace="/" extends="struts-default">
	<action name="locale" class="com.h3.common.action.localeaction">
		<result name="success">pages/welcome.jsp</result>
		<param name="englishparam">english</param>
    	        <param name="chineseparam">chinese</param>
     	        <param name="franceparam">france</param>
	</action>
   </package>	
</struts>

从动作获取静态参数

要从struts.xml中获取静态参数值，action类必须实现参数化parameterizable接口。动作的静态参数是由staticparams拦截，其中包括在默认堆栈控制

1. map属性

//...
import com.opensymphony.xwork2.config.entities.parameterizable;

public class localeaction implements parameterizable{

	map<string, string> params;
	//...
	public void setparams(map<string, string> params) {
		this.params = params;
	}
}

2. javabean 属性

在动作类的初始化，如果创建了getter和setter方法得当，staticparams拦截器将设置预先定义的参数值，以对应于该“参数”的每javabean属性。

//...
import com.opensymphony.xwork2.config.entities.parameterizable;

public class localeaction implements parameterizable{

	string englishparam;
	string chineseparam;
	string franceparam;
	
	public string getenglishparam() {
		return englishparam;
	}

	public void setenglishparam(string englishparam) {
		this.englishparam = englishparam;
	}

	public string getchineseparam() {
		return chineseparam;
	}

	public void setchineseparam(string chineseparam) {
		this.chineseparam = chineseparam;
	}

	public string getfranceparam() {
		return franceparam;
	}

	public void setfranceparam(string franceparam) {
		this.franceparam = franceparam;
	}
    //...
}
