留言版是默认的吗？

回复第2楼
   是默认的，我只是想配置出来，模板方案设置我已经选好了，模板不是在默认路径

您改动了些什么地方？

回复第4楼
     看了一下好像都没修改过啊

不可能没有改动吧，没改动默认程序是没这个问题的。

回复第6楼
   能看出大概是什么地方，什么原因出现的这种问题吗？

改动过肯定不清楚是什么原因造成的，首先要确定改动了什么地方

回复第8楼
     感谢斑竹的及时回复！ 
   我这修改了UrlInterceptor.java里面的doIntercept方法，就下面这点代码注释了一些，其他地方没有修改了，吧它还原还是不行。
                else
                {
//                    // 去掉下划线"_"。
//                    String page = url.substring(preIndex + 1, suffixIndex);
//                    try
//                    {
//                        aware.setPageNo(Integer.parseInt(page));
//                    }
//                    catch (Exception e)
//                    {
                        aware.setPageNo(1);
//                    }
                }

重启下看看，不行就把源码覆盖下看看
