Question

我在Eclipse中遇到Tomcat问题;当我运行一个简单的Servlet时，Tomcat（在Eclipse中）没有向我显示该页面，但它要求我下载它！有代码。我该怎么办才能修复它？源代码位于..Documents \ Workspace \ Servlet02 \ src \ mypkg \ SimpleServlet

package mypkg;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;
import javax.servlet.ServletException;
import javax.servlet.http.*;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.annotation.*;

@SuppressWarnings("unused")
@WebServlet(name = "SimpleServlet", urlPatterns = {"/SimpleServlet"})
public class SimpleServlet extends HttpServlet {

    Date currDateAndTime;

    private static final long serialVersionUID = 1L;

    protected void processRequest(HttpServletRequest request , HttpServletResponse response) throws IOException , ServletException{
        response.setContentType("html/text ; charset=UTF-8 ");
        PrintWriter out = response.getWriter();
        try {
            out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet CurrentDateAndTime</title>");
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>Servlet CurrentDateAndTime at " + request.getContextPath() + "</h1>");
            out.println("<br/>");
            synchronized(currDateAndTime){
                currDateAndTime = new Date();
                out.println("The current date and time is: " + currDateAndTime);
            }
            out.println("</body>");
            out.println("</html>");
            } finally {
            out.close();
            }
    }
    @Override
    protected void doGet(HttpServletRequest request , HttpServletResponse response)  throws IOException , ServletException{
        processRequest(request,response);
    }

    @Override
    protected void doPost(HttpServletRequest request , HttpServletResponse response) throws IOException , ServletException{
        processRequest(request,response);
    }

    @Override
    public String getServletInfo() {
        return "Short description";
    }// </editor-fold>


}

Answer 1

问题是由于线下。

response.setContentType("html/text ; charset=UTF-8 ");

应该是

response.setContentType("text/html; charset=UTF-8");

或完全删除它或使用

response.setContentType("text/html");
response.setCharacterEncoding("UTF-8");

在Documentation

中详细了解相关信息

使用字符串setContentType(java.lang.String)调用text/html并使用字符串UTF-8调用此方法与使用字符串setContentType调用text/html; charset=UTF-8等效。

Answer 2

应该是

 response.setContentType("text/html");
 response.setCharacterEncoding("UTF-8");

Tomcat只允许我下载servlet
