Question

我想在 Java语中用一台服务器书写超文本。我读了<代码>doGet(),我写了这一简单例子。

public void doGet(HttpServletRequest request, HttpServletResponse response) throws  IOException { 
PrintWriter out = response.getWriter(  ); 
response.setContentType("text/html"); 
out.println("<H1>Hello from a Servlet</h2>");

但是,在浏览器中,谁能告诉我什么错误?

Answer 1

The standard PrintWriter which you get by calling response.getWriter(); doesn t automatically flush its buffers. It s a bug/feature.

还注意到<代码>PrintWriter.close()does not flush。缩略语:PrintWriter/PrintStream是没有近变的唯一产出类别。

<><>> 确保没有任何其他问题混淆你,在方法上添加一个断点,并将其推向泡沫。页: 1 为确保您的签名方法正确而超文本。

Answer 2

看来,你实际上并没有凌驾于 do。您忽略了<代码>ServletException的例外情况。
