Question

我正在向servlet添加一些HTML代码但是当我粘贴代码时，Eclipse会抛出一个错误，说String literal is not properly closed by a double-quote。

我试图通过检查HTML块的语法来解决这个问题，但似乎是正确的。

有人能在声明中发现错误吗？

这是令人讨厌的代码：

out.println (
      "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" 
          \"http://www.w3.org/TR/html4/loose.dtd\">\n" +
      "<html> \n" +
        "<head> \n" +
          "<meta http-equiv=\"Content-Type\" content=\"text/html; 
            charset=ISO-8859-1\"> \n" +
          "<title> My first jsp  </title> \n" +
        "</head> \n" +
        "<body> \n" +
          "<font size=\"12px\" color=\"" + color + "\">" +
            "Hello World" +
          "</font> \n" +
        "</body> \n" +
      "</html>" 
    );

Answer 1

你必须加入这些行：

out.println ( "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" \"http://www.w3.org/TR/html4/loose.dtd\">\n" + "<html> \n" + "<head> \n" + "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=ISO-8859-1\"> \n" + "<title> My first jsp</title> \n" + "</head> \n" + "<body> \n" + "<font size=\"12px\" color=\"" + color + "\">" + "Hello World" + "</font> \n" + "</body> \n" + "</html>" );

你有两个换行符，试试这个：

out.println (
      "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" 
          \"http://www.w3.org/TR/html4/loose.dtd\">\n" + // here is linebreak one - error1
      "<html> \n" +
        "<head> \n" +
          "<meta http-equiv=\"Content-Type\" content=\"text/html; 
            charset=ISO-8859-1\"> \n" + // here is linebreak two - error2
          "<title> My first jsp  </title> \n" +
        "</head> \n" +
        "<body> \n" +
          "<font size=\"12px\" color=\"" + color + "\">" +
            "Hello World" +
          "</font> \n" +
        "</body> \n" +
      "</html>" 
    );

修正：

public static void main(String[] args)
    {
        String color = "";
        String test =
                "<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" \"http://www.w3.org/TR/html4/loose.dtd\">\n" +
            "<html> \n" +
              "<head> \n" +
                "<meta http-equiv=\"Content-Type\" content=\"text/html; charset=ISO-8859-1\"> \n" +
                "<title> My first jsp  </title> \n" +
              "</head> \n" +
              "<body> \n" +
                "<font size=\"12px\" color=\"" + color + "\">" +
                  "Hello World" +
                "</font> \n" +
              "</body> \n" +
            "</html>";
        System.out.println(test);
    }
