將list轉為json字符串

//確保JSP和servlet的編碼方式一致
resp.setContentType("text/html;charset=GBK");
List<String> jymdList = new ArrayList<String>();
PrintWriter out = null;
    try {
        //從數據庫中取得List
        jymdList = efileViewUiService.getLymd();
        //簡單粗暴,對於Map這句也適用
        String json = JSON.toJSONString(jymdList);
        //取得流向JSP傳遞數據    
        PrintWriter out = resp.getWriter();
        out.print(json);
    } catch (BaseException e) {
        e.printStackTrace();
    } finally{
        out.close();      
    }
