使用这种形式的全局异常跳转，记录日志得写在jsp页面上

<global-exception-mappings>
			<exception-mapping result="error" exception="java.lang.Exception">/errorPage.jsp
			</exception-mapping>
</global-exception-mappings>

所以自定义一个拦截器，再拦截器里记录异常

<package name="basePriv" extends="struts-default">
		<interceptors>
			
			<interceptor name="exceptionInterceptor" class="com.hanpeng.b2c.phone.priv.ExceptionInterceptor"/>  
			
			<interceptor-stack name="b2cplatPrivInterceptor">
				<interceptor-ref name="exceptionInterceptor"/>  
				<interceptor-ref name="defaultStack"/>
			</interceptor-stack>
			
		</interceptors>
		
		<default-interceptor-ref name="b2cplatPrivInterceptor"/>
		
		<global-results>
			<result name="error">/error.jsp</result>
		</global-results>
		
</package>

拦截器实现

package com.hanpeng.b2c.phone.priv;

import org.apache.log4j.Logger;

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



public class ExceptionInterceptor extends AbstractInterceptor {

	 
	private static final long serialVersionUID = 1008901298342362080L;
	private static final Logger log = Logger
			.getLogger(ExceptionInterceptor.class);

	@Override
	public String intercept(ActionInvocation invocation) throws Exception {
		String actionName = invocation.getInvocationContext().getName();
		try {
			String result = invocation.invoke();
			return result;
		} catch (Exception e) {
			log.error(actionName, e);
			return "error";
		}
	}
}
