Answer 1

您需要使用 restful url 注释您的控制器方法，并将 @ResponseBody 注释添加到控制器方法。

例子：

@Controller
@RequestMapping(value = "/pets")
@ResponseBody
public Pet getPet(@PathVariable String petId, Model model) {    
    //..generate some Json
    // Add Json to the Response
    model.addAttribute("json", json);
}

然后在你的 js 中使用 jquery 对 URL 进行 ajax 调用

$.ajax({
  type: 'POST',
  url: "/pets",
  data: data,
  success: function(data){
   alert(data.json); //alerts json object
},
  dataType: 'json'
});
