(Spring + JSP + jQuery-AJAX + JSON ) setting environment for UTF-8 issue?

Question

I am doing a chat project in java with Spring 3.x which needs Multi-language support.

Here is what I have done.

Answer 1

I have tried your javascript with this test controller:

@Controller
public class TestController {
    @RequestMapping(value = "/test", method = POST, produces = "application/json; charset=utf-8")
    public @ResponseBody
    ResponseEntity sendMessage(HttpSession session, @RequestParam String intxnId, @RequestParam String message, HttpServletRequest request, HttpServletResponse response) {

        System.out.println("Send Message UTF-8 ----------------- " + message);

        String json = null;
        HashMap result = new HashMap();
        result.put("name", "test");
        result.put("message", message);
        result.put("time", "time");
        ObjectMapper map = new ObjectMapper();
        if (!result.isEmpty()) {
            try {
                json = map.writeValueAsString(result);
                System.out.println("Send Message  :::::::: : " + json);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        HttpHeaders responseHeaders = new HttpHeaders(); 
        responseHeaders.add("Content-Type", "application/json; charset=utf-8"); 
        return new ResponseEntity(json, responseHeaders, HttpStatus.CREATED);
    }
}

It works like a charm, and I see UTF-8 characters from the response in the alert popup, using chrome browser.

My test.jsp:

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%request.setCharacterEncoding("UTF-8");%>
