上面的方法试了没有成功,可能是自己哪个地方代码有问题没有找到,最后自己试验了一种方式成功解决了中文乱码问题,记录下来。

1.修改struts.xml配置文件
class="xml" name="code">修改前的: <action name="recheckOrderBill" class="recheckOrderBillAction"> <result name="success" type="redirect"> orderBillShow?msg=${msg} </result> </action> 修改后的: <action name="recheckOrderBill" class="recheckOrderBillAction"> <result name="success" type="redirect"> <param name="location">orderBillShow?msg=${msg}</param> <param name="encode">true</param> </result> </action>

?2.修改调用重定向action的action:
private String msg; public String execute() throws Exception { //在该action对需要传递的参数进行编码 //编码方式:URLEncoder.encode("str", "UTF-8"); msg = URLEncoder.encode(cusStdOrderbillBL.recheckOrderbill(relationId), "UTF-8"); return SUCCESS; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; }
?
?3.修改重定向后的action:
private String msg ; public String execute() throws Exception { //此处对重定向传递过来的msg进行解码 //解码方式:URLDecoder.decode(getMsg(), "UTF-8"); if (msg != null) { msg = URLDecoder.decode(getMsg(), "UTF-8"); setMsg(msg); } return SUCCESS; } public String getMsg() { return msg; } public void setMsg(String msg) { this.msg = msg; }

?4.页面显示:
el表达式方式:${msg} strut2标签方式:<s:property value="msg"/>
