### jquery ajax 序列化 ###

**应用：将表单序列化，使用ajax传递到后端服务器**

### \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\* ###

**示例**

**HelloController**

@RestController
    public class HelloController {
    
        @RequestMapping("/hello4")
        public String hello4(Person person){
            return person.toString();
        }
    
        @RequestMapping("/hello5")
        public Map<String,Object> hello5(Person person){
            Map<String,Object> map=new HashMap<>();
            map.put("id",person.getId());
            map.put("name",person.getName());
            map.put("age",person.getAge());
    
            return map;
        }
    
        @RequestMapping("/hello6")
        public Map<String,Object> hello6(@RequestBody Person person){
            Map<String,Object> map=new HashMap<>();
            map.put("id",person.getId());
            map.put("name",person.getName());
            map.put("age",person.getAge());
    
            return map;
        }
    }
