我有问题
using Gzip compression and JQuery together.似乎这可能是由我的方式发送JSON响应在我的Struts操作.我使用下一个代码发回我的JSON对象.
public ActionForward get(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) {
JSONObject json = // Do some logic here
RequestUtils.populateWithJSON(response,json);
return null;
}
public static void populateWithJSON(HttpServletResponse response,JSONObject json) {
if(json!=null) {
response.setContentType("text/x-json;charset=UTF-8");
response.setHeader("Cache-Control","no-cache");
try {
response.getWriter().write(json.toString());
} catch (IOException e) {
throw new ApplicationException("IOException in populateWithJSON",e);
}
}
}
在Java Web应用程序中是否有更好的方式发送JSON？
解决方法
代替
try {
response.getWriter().write(json.toString());
} catch (IOException e) {
throw new ApplicationException("IOException in populateWithJSON",e);
}
尝试这个
try {
json.write(response.getWriter());
} catch (IOException e) {
throw new ApplicationException("IOException in populateWithJSON",e);
}
因为这将避免创建一个字符串,并且JSONObject将直接将字节写入Writer对象
