Question

所以，我的hean敲打了3个小时后终于寻求帮助了

<%@ page import="net.sf.json.*" %>

..
.
.



<%
     while (rs.next()) {
     %>
      <%
    json = (JSONObject) JSONSerializer.toJSON(rs.getString(3));
    System.out.println(json.toString());

    System.out.println(json.getString('site_caption'));//Compiler failed
    System.out.println(json.get('site_caption'));//Compier failed

    }
    %>

以上代码在控制台中打印

{ "font_color" : "#0079cd",
  "site_background" : { "color" : "",
      "image" : "",
      "selected" : "image"
    },
  "site_caption" : "<p>Site Caption</p>\r\n",
  "site_description" : "<p>Site Description</p>\r\n",
  "site_logo" : { "image" : "1361858536dyn007or53.gif",
      "selected" : "image",
      "text" : ""
    }
}

但是当我试图打印时

    System.out.println(json.getString('site_caption'));//Compiler failed
    System.out.println(json.get('site_caption'));//Compier failed

甚至没有给出正确的错误消息

我受到同样的错误消息的骚扰

Compile failed; see the compiler error output for details.

    at org.apache.jasper.compiler.Compiler.generateClass(Compiler.java:382)
    at org.apache.jasper.compiler.Compiler.compile(Compiler.java:472)

请把我拖出来。

感谢。

您的密钥应使用双引号"进行转义，而非单引号'。 E.g：

System.out.println(json.getString("site_caption"));

Json Object get或getString在Jsp中给出编译错误
