Answer 1

前台js
$(document).ready(function(){
var url="http://192.168.23.16:8081/yhjw/getTest"+"?id=1&callback=?";
$.ajax({
url:url,
dataType:'jsonp',
processData: false,
type:'get',
success:function(data){
alert(data.message);
},
error:function(XMLHttpRequest, textStatus, errorThrown) {
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.readyState);
alert(textStatus);
}});
});

后台代码
@RequestMapping(value = "/getTest")

public void getGroupById(@RequestParam("id") Long id,
HttpServletRequest request, HttpServletResponse response)
throws IOException {
String callback = request.getParameter("callback");
response.setContentType("text/html");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
out.print(callback + "({\"message\":\"成功\"})");
}
