Answer 1

你需要用restful url来注释你的控制器方法，并在控制器方法中添加一个@ResponseBody注释。

的例子:

@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'
});
