很明显，屏蔽response.setContentType("application/vnd.ms-excel");后，在Test.writeExcel(response.getOutputStream());之前，response.reset(); 之后没有设置response contenttype的正确类型，当然输出为乱码了。而正确输出excel的jsp的编译后源码是这样的:
public void _jspService(javax.servlet.http.HttpServletRequest request,
javax.servlet.http.HttpServletResponse response) throws java.io.IOException,
javax.servlet.ServletException
{
// declare and set well-known variables:
javax.servlet.ServletConfig config = getServletConfig();
javax.servlet.ServletContext application = config.getServletContext();
javax.servlet.jsp.tagext.Tag _activeTag = null;
// variables for Tag extension protocol
Object page = this;
javax.servlet.jsp.JspWriter out;
javax.servlet.jsp.PageContext pageContext =
javax.servlet.jsp.JspFactory.getDefaultFactory().getPageContext(this, request, response, null, true, 8192, true);
out = pageContext.getOut();
JspWriter _originalOut = out;
javax.servlet.http.HttpSession session = request.getSession(true);
try { // error page try block
out.print("rn");
//[ /test_excel.jsp; Line: 2]
response.reset(); //[ /test_excel.jsp; Line: 3]
response.setContentType("application/vnd.ms-excel"); //[ /test_excel.jsp; Line: 4]
Test.writeExcel(response.getOutputStream()); //[ /test_excel.jsp; Line: 5]
} catch (Throwable __ee) {
