jquery ajax springMVC 解决跨域问题

1.首先要引入jquery.jsonp.js

2. 前端

       var url = "http://10.12.1.134:8080/community/api/place/basePlaceCount/list?type=tag_type&tagLog=1&callback=?";
       $.jsonp({
          url: url,
          success: function(data) {
          console.log(data);
          },
          dataType: 'jsonp',  
          jsonpCallback:'jsonpCallback',
          error: function(d,msg) {
          }
    });

3.springMVC

 @RequestMapping(value = {"list", ""})
 @ResponseBody
 public Object list(BasePlaceCount basePlaceCount, HttpServletRequest request, HttpServletResponse response, Model model) { 
     Map<String,Object> result = new HashMap<String, Object>();
     User loginUser = UserUtils.getUser();
     basePlaceCount.setTenantId(loginUser.getTenantId());
     List<BasePlaceCount> basePlaceCounts = new ArrayList<BasePlaceCount>();
     basePlaceCounts = basePlaceCountService.findList(basePlaceCount);
     result.put("basePlaceCounts", basePlaceCounts);
     String callback = request.getParameter("callback");
     MappingJacksonValue mmp = new MappingJacksonValue(basePlaceCounts);
     mmp.setJsonpFunction(callback);
     return mmp;
 }
