echarts java json问题

[fengbrute]

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

忘说了 问题是 jsp页面myChart.setOption(option);页面怎么也出不来，是不是我optionjson格式问题

[爵爷一回眸]

你先去校验一下json格式是不是正确的，有个网站可以校验，如果正确的，在js里用JSON.parse或者eval转换一下，而且geoCoord和data之类的是json格式的，option是json格式的么？
