spring mvc前端传json，后端怎么直接对象获取

Question

在项目中碰到问题了
就是我前端ajax传一个json过了， 我后端用在spring mvc
怎么直接用对象去接收？

Answer 1

[code="java"]
可以在ajax里面填写
$.ajax({
url: "/spring-mvc-json/rest/cont/person",
type: 'POST',
dataType: 'json',
data: "{\"name\":\"hmkcode\",\"id\":2}",
contentType: 'application/json',
mimeType: 'application/json',
success: function(data) {
alert(data.id + " " + data.name);
},
error:function(data,status,er) {
alert("error: "+data+" status: "+status+" er:"+er);
}
});

而在controller里面配置
@RequestMapping(value="person", method = RequestMethod.POST)
public @ResponseBody Person post( @RequestBody final Person person) {

  System.out.println(person.getId() + " " + person.getName());
  return person;

}
