at 执行hibernate删除方法时，由于数据库此表中没有设置自动标识，所以只能使用字符串删除，传入custNo与custName值，传入的custNo为英文与数字正常，但传入custName值时中文出现乱码，转换编码写了encoding拦截，也在struts2中设置了struts.i18n.encoding编码，但是传进去的值还是乱码。
<img onclick="del('cust!doCustDel.action?cust.custNo=${c.custNo }&cust.custName=${c.custName }');" title="删除" src="/crm/images/bt_del.gif" class="op_button" />
一、页面的编码utf-8
二、配置个过滤器 spring已经提供了一个过滤器
三、最好统一编码为utf8
