请帮帮我。 JSON对象SyntaxError：JSON解析错误：未终止的字符串

JAVA代码

    @RequestMapping(value = "getMessage.htm")
public @ResponseBody String getStatusServer(ModelMap model, HttpSession session,@RequestParam("key") String key)
        throws InterruptedException, ExecutionException {
    BufferData bufferData = DataMap.dataMap.get(key);
    StringBuilder content = new StringBuilder();
    content.append("{\"status\":").append(bufferData.getStatus()).append(",").append("  \"messages\": \"").append(bufferData.getMess()).append("\"}");
    System.out.println(content.toString());

    return content.toString();
}

JQuery代码

    $.ajax({
        type : 'GET',
        url : "<c:url value="/"/>" + "getMessage.htm",
        data : 'key=' + 'job1',
        dataType : "json",
        success : function(data) {
            alert("test");
            alert(JSON.stringify(data));
        },
        error : function(data, status, er) {
            alert("error: " + data + " status: " + status + " er:" + er);
        }

    });
}

请帮帮我。和json输出

Answer 1

这看起来不像是有效的json，请尝试下面的内容，看看它是否会发送。

data = {
            "key": "job1"
        }

Answer 2

我不确定，你想用线做什么？ url : "<c:url value="/"/>" + "getMessage.htm",

如果这是nexted字符串值，请尝试使用此单个代码而不是double。

url : "<c:url value='/'/>" + "getMessage.htm"
