action代码
public String getQuestion() throws Exception{
String fvQstate = this.getRequest().getParameter("fvQstate");
String sql="";
if (StringUtils.isBlank(fvQstate)){
sql="select distinct FV_QSTATE from brw_question where FV_QSTATE= "+fvQstate;
}
brwQuestionList=questionServer.findBySQLList(sql);
this.jsonForm.setSuccess(false);
this.jsonForm.setData(brwQuestionList);
this.jsonForm.setSuccess(true);
log.info(brwQuestionList.size());
return SUCCESS;
}
能查到数据,但页面接收不到值 JSON JSP String SQL 类
[解决办法]
public void getQuestion(){
String json = "";
getResponse().setContentType("text/html;charset=utf-8");
String fvQstate = this.getRequest().getParameter("fvQstate");
try {
if (StringUtils.isBlank(fvQstate)){
sql="select distinct FV_QSTATE from brw_question where FV_QSTATE= "+fvQstate;
}
brwQuestionList=questionServer.findBySQLList(sql);
Map<String, Object> map = new HashMap<String, Object>();
map.put("brwQuestionList", brwQuestionList);
JSONObject jsonObject = JSONObject.fromObject(map);
json = JSONObject.fromJSONObject(jsonObject).toString();
getResponse().getWriter().print(json);
} catch (Exception e) {
e.printStackTrace();
}
}应该这样写
