解决方式一、
js代码
$(document).ready(function(){
var url='http://localhost:8080/WorkGroupManagment/open/getGroupById"
+"?id=1&callback=?';
$.ajax({
url:url,dataType:'jsonp',processData: false,type:'get',success:function(data){
alert(data.name);
},error:function(XMLHttpRequest,textStatus,errorThrown) {
alert(XMLHttpRequest.status);
alert(XMLHttpRequest.readyState);
alert(textStatus);
}});
});
后台java代码：
@RequestMapping(value = "/getGroupById")
public String getGroupById(@RequestParam("id") Long id,HttpServletRequest request,HttpServletResponse response)
throws IOException {
String callback = request.getParameter("callback");
ReturnObject result = null;
Group group = null;
try {
group = groupService.getGroupById(id);
result = new ReturnObject(group,"获取成功",Constants.RESULT_SUCCESS);
} catch (BusinessException e) {
e.printstacktrace();
result = new ReturnObject(group,"获取失败",Constants.RESULT_Failed);
}
String json = JsonConverter.bean2Json(result);
response.setContentType("text/html");
response.setCharacterEncoding("utf-8");
PrintWriter out = response.getWriter();
out.print(callback + "(" + json + ")");
return null;
}
解决方式二、
使用jsonp
var url="http://localhost:8080/WorkGroupManagment/open/getGroupById"
+"?id=1&callback=?";
$.jsonp({
"url": url,"success": function(data) {
alert(data.result.name);
},"error": function(d,msg) {
alert("Could not find user "+msg); }});
