echarts java json问题

我用echarts 的java类库 通过ajax获取后台的option的json（用的是JSONObject.fromObject(option)）传到页面用的是printWriter.write(JSONObject.fromObject(option).toString());代码如下

printWriter.write(JSONObject.fromObject(option).toString());
System.out.println(JSONObject.fromObject(option));
printWriter.flush();
printWriter.close();

json格式类似
