如何從MySQL中獲取語言Malayalalam數據和通過Java REST API

Question

在瀏覽器中顯示它在我的MySQL表我在馬拉雅拉姆語（utf8mb4_unicode_520_ci）有數據。我的REST API獲取使用的JdbcTemplate並在瀏覽器中顯示的數據。看到的內容所需的字體已經安裝在系統中。但內容仍然如下所示。

謾Â'¡ÃÂ'²ÃÂμ�ââ,¬ï¿½ÃÂ'¹ÃÂ'¿ÃÃ'ÂÃÂ'¿ÃÂ'²ÃÂμÀ這Â'ªà ÂμÃÃÂ'¤ÃÂμ�ÃÂ'®ÃA'A°的Â'¾ÃÂ'®ÃÂ'¤ÃÂμ�ÃÂ'¤ÃÂμ�ÃÂ'®ÃÂ用於從數據庫獲取數據'¾ÃÃ'ÂÃ

代碼。

List<News> listNewsPosts = new ArrayList<News>(); 
    query = "SELECT * FROM malayalam_dictionary"; 
    listNewsPosts = jdbcTemplate.query(query, 
    new BeanPropertyRowMapper<News>(News.class)); 

我這是如何將數據返回到瀏覽器

@GET 
    @Path("/posts/) 
    @Produces(MediaType.APPLICATION_JSON) 
    public Response getAllPosts() { 
    Date dNow = new Date(); 
    SimpleDateFormat ft = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss"); 
    APIResponse apiResponse = new APIResponse(); 
    apiResponse.setMessage("Fetched posts successfully!"); 
    apiResponse.setResponseTime(ft.format(dNow)); 
    try { 
    Map<String, Object> categories = new HashMap<String, Object>(); 
    categories.put("newsDetail", newsOperationsController.getAllPosts()); 
    apiResponse.setResponse(categories); 
    return Response.ok(apiResponse).build(); 
    } catch (Exception e) { 
    logger.error(e, e); 
    apiResponse.setMessage("Something went wrong. please try again!"); 
    return Response.status(500).entity(apiResponse).build(); 
    } 
    } 

請幫我在正確的格式返回API數據。

感謝
