Bad coding when returning a string using Spring MVC & ajax

I have a webpage that requests a text string using Ajax, but the string is returned as '??????'

It is strange that when you insert the same line into a page using JSTL, not Ajax, it displays correctly ...

On my webpage I declare

<%@ page contentType="text/html" pageEncoding="UTF-8"%>

What is my controller:

@RequestMapping("get_label")   
public @ResponseBody String getLabel()
{
   String str = "בדיקה";

   return str;
}

And my ajax request:

$.ajax({
    url:    "get_label",
    success:    function(result)
    {
        alert(result);
        $("#parameter_select label").text(result);
    }
});

Any ideas what I'm doing wrong here?

This is because, by default, AJAX calls use the default encoding of the browser (for example, ANSI). To do this, you need to do the following:

jQuery style - mimeType :

$.ajax({
    url:    "get_label",
    mimeType:"text/html; charset=UTF-8",
    success:    function(result)
    {
        alert(result);
        $("#parameter_select label").text(result);
    }
});

Vanilla JS style :

xhr.overrideMimeType("text/html; charset=UTF-8")

, . :

  • UTF-8 - ( Tomcat) URIEncoding = "UTF-8" server.xml; .
  • ( ), , , UTF-8.

:

@RequestMapping("get_label")
public @ResponseBody String getLabel(HttpServletResponse response)
{
    String str = "בדיקה";

    //set encoding explicitly
    response.setCharacterEncoding("UTF-8");

    return str;
}

, @ResponseBody Spring 3.1 +:

@RequestMapping(value = "get_label", produces = "text/html; charset=UTF-8")
public @ResponseBody String getLabel(HttpServletResponse response)
{
    String str = "בדיקה";

    return str;
}

, AJAX- UTF-8 , :

  • -
  • - UTF-8
  • AJAX UTF-8
