需要做转换，乱码

}

pVo.setDate(str_date_date);

pVo.setIssueDate(str_date_issueDate);

pVo.setDoctypeId(patent.getDoctype().getId());

pVo.setDoctypeName(patent.getDoctype().getName());

pVo.setUserId(patent.getUser().getId());

pVo.setUserName(patent.getUser().getName());

 

包含实体类的，放在Vo里

/**     * 根据关键字获取专利详细信息     */    public String loadDataByKeyWord() {        key = Iso2Utf.encode(key);        List
     
       patents = patentservice.getListByKeyWord(key);        List
      
        patentVos = new ArrayList
       
        ();        for (Patent patent : patents) {            PatentVo patentVo = new PatentVo();            try {                BeanUtils.copyProperties(patentVo, patent);            } catch (Exception ex) {                ex.printStackTrace();            }            patentVo.setDoctypeId(patent.getDoctype().getId());            patentVo.setDoctypeName(patent.getDoctype().getName());            patentVo.setDate(sd.format(patent.getDate()));            patentVo.setIssueDate(sd1.format(patent.getIssueDate()));            patentVos.add(patentVo);        }        String jsonResult = JSONArray.fromObject(patentVos).toString();        try {            response.getWriter().write(jsonResult);        } catch (Exception e) {            e.printStackTrace();        }        return null;    }
       
      
     

后台java代码，不允许setId

传代数值的，先传id（id：id）
