spring mvc前端传json，后端怎么直接对象获取

比如传stats={ "firstName" : "Elmer", "lastName" : "Fudd" }
在你的controller层这么写就对了：
@ResponseBody @RequestMapping("/description")
public Description getDescription(@RequestBody UserStats stats){
return new Description(stats.getFirstName() + " " + stats.getLastname() + " hates wacky wabbits");
}
// domain / value objects
public class UserStats{
private String firstName;
private String lastName;
// + getters, setters
}
public class Description{
private String description;
// + getters, setters, constructor
}
