假設你發現Spring 4 MVC的Post請請求亂碼，請加入accept-charset的標簽為utf-8就能解決。例如以下：

            <form name="user" action="add.html" method="post"
                    accept-charset="utf-8">
                Firstname: <input type="text" name="firstname"> <br>
                Lastname: <input type="text" name="lastname">   <br>
                <input type="submit" value="   Save   ">
            </form>

Spring 4 MVC的post提交form時中文亂碼
