out.println说出来无法解决

问题描述

当我写 out.println（）时，eclipse会抱怨无法解决。

When I write out.println(), eclipse complains that out cannot be resolved.

我有导入 java.io。* 和其他servlet包。

I have imported java.io.* and other servlet packages.

推荐答案

在黑暗中拍摄，我认为这是你要找的 out ：

Just a shot in the dark, I think this is the out you are looking for:

public class OutServlet extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("foo");
    }
}
