现在web.xml配置文件的标签是红色，也是红色。这里到底有啥问题呢？
ServletTest是工程名称 BaseServlet 是一个类。
里面get方法中很简单的代码
public class BaseServlet extends HttpServlet{
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException,IOException{
System.out.print("客户端访问我了2");
doGet(request,response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException,IOException{
System.out.print("客户端访问我了1");
//this.doPost(request,response);
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String title = "HTTP Header 请求实例 - 菜鸟教程实例";
String docType =
"<!DOCTYPE html> \n";
out.println(docType +
"<html>\n" +
"<head><meta charset=\"utf-8\"><title>" + title + "</title></head>\n"+
"<body bgcolor=\"#f0f0f0\">\n" +
"<h1 align=\"center\">" + title + "</h1>\n" +
"<table width=\"100%\" border=\"1\" align=\"center\">\n" +
"<tr bgcolor=\"#949494\">\n" +
"<th>Header 名称</th><th>Header 值</th>\n"+
"</tr>\n");
Enumeration headerNames = request.getHeaderNames();
while(headerNames.hasMoreElements()) {
String paramName = (String)headerNames.nextElement();
out.print("<tr><td>" + paramName + "</td>\n");
String paramValue = request.getHeader(paramName);
out.println("<td> " + paramValue + "</td></tr>\n");
}
out.println("</table>\n</body></html>");
}
这么点代码咋都不能运行呢
