在Struts2拦截器中获取请求action名称及参数

1.Interceptor配置

<package name="sysManageServices" namespace="/" extends="struts-default">
		<interceptors>
            <interceptor name="reqCheck" class="interceptor.RequestInterceptor"/>
            <interceptor-stack name="teamwareStack">
                <interceptor-ref name="requestCheck"/>
                <interceptor-ref name="defaultStack"/>
            </interceptor-stack>
		</interceptors>
		<default-interceptor-ref name="teamwareStack"/>
		<action name="searchUserInfo" class="action.SearchUserInfoAction">
			<result name="success">/page/userManage.jsp</result>
			<result name="error">/page/result.jsp</result>
		</action>
	</package>

2.拦截器代码

package interceptor.RequestInterceptor;

import java.util.Map;

import javax.servlet.http.HttpSession;

import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

public class RequestInterceptor extends AbstractInterceptor {

	private static final long serialVersionUID = 3244973830196015811L;
	private HttpSession session;

	public void setSession(Map<String, Object> session) {
		this.session = (HttpSession) session;
	}

	public String intercept(ActionInvocation aInvocation) throws Exception {
		
		// 获取请求的action名称
		String actionName = aInvocation.getInvocationContext().getName();
		
		// 获取action后附带参数
		Map parameters = aInvocation.getInvocationContext().getParameters();
		
		if (hrefList.contains(requestName)) {
        	String result = actionInvocation.invoke();
        	return result;
        } else {
        	ActionSupport aSupport =  (ActionSupport) actionInvocation.getAction();
        	aSupport.addActionMessage("不存在该页面！请返回");
        	return Action.ERROR;
        }	
}
