Struts2配置Action类的静态参数

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.yiibai.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;
	}
    //...
}
