今天是中秋节哟~~ --------------------------------------------
这2天一直在努力解决ecside2.0RC1在weblogic8.1.6环境下导出xls,csv 文件为空的情况~
期间 xiaotiaotiao 的一篇帖子给我不少灵感~
-------------------------------------
在1.3版本里对比看了下
发现XlsView里面的用到的outputstream
改为1.3版本的ByteArrayOutputStream
同时在beforeBody里改为outputStream=new ByteArrayOutputStream
-----------------------------------------------------------
于是我就尝试改了一下csvView.java结果成功了~开心了半天~
但是，用同样方法的处理xlsView.java却一直不成功，继续郁闷......
今天，我干脆从头到尾把csvView,xlsView做了一下比较和研究~发现xlsView是比csvView缩水处理了~~呵呵
注意原版xlsView和csvView在以下片段不同~
private ByteArrayOutputStream outputStream ;
private ByteArrayOutputStream outputStreamOut;
private PrintWriter out =null;
csvView 是定义了以上3个供输出的属性~而xlsView只有 outputStream 这一个！！
今天偶然又看了一下XlsViewResolver.java文件。。发现问题了~~~居然里面的代码给注释掉了...
这时候我在看xlsView的afterBody方法 发现直接返回outputStream对象~~
********************************************************
可能fins的本来的想法是直接把xls流提交给IE浏览器，让它自己解析出XLS文件下载~
没有使用PrintWriter方法输出！！事实证明TOMCAT5.5是可以的，WEBLOGIC就不可以~
********************************************************
好了，问题找到了·解决起来就快了~~~~
参考CsvView,CsvViewResolver对XlsView,XlsViewResolver做了修改
总结如下（Weblogic8.1.6,JDK1.4环境;TOMCAT 5.5 JDK1.6环境全部通过）：
