Ajax提交乱码

1. 页面码 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

   1.1 如下图，传入到后台，显示正常，不为乱码  

 $.ajax({
                        url:"/flowctrl/saveMessageAction.do?message="+"姓名",
                        type: "get",
                        //data:{message:aa},
                        dataType: "text",
                        success: function(data){
                              alert("发布成功!");
                              $("#content").html("");
                         },
                        error: function(data){
                             alert("发布失败！");
                         }
                     });

   1.2 如下图，传入到后台，显示为乱码

 $.ajax({
                        url:"/flowctrl/saveMessageAction.do",
                        type: "get",
                        data:{message:"姓名"},
                        dataType: "text",
                        success: function(data){
                              alert("发布成功!");
                              $("#content").html("");
                         },
                        error: function(data){
                             alert("发布失败！");
                         }
                     });

解决办法：

   强制转换为UTF-8

 $.ajax({
                        url:"/flowctrl/saveMessageAction.do",
                        type: "get",
                        data:{message:encodeURI("姓名",UTF-8")},
                        contentType: "application/x-www-form-urlencoded; charset=utf-8",
                        dataType: "text",
                        success: function(data){
                              alert("发布成功!");
                              $("#content").html("");
                         },
                        error: function(data){
                             alert("发布失败！");
                         }
                     });

后台代码：

   接收时也需要强制转换回来，URLDecoder.decode(message,"UTF-8");
