1、创建一个类来实现AnnotationFormatterFactory接口

 通过实现Formatter接口自定义自已的规则

PersonFrommId注解代码:

@Documented@Retention(RetentionPolicy.RUNTIME)@Target({ElementType.METHOD, ElementType.FIELD, ElementType.PARAMETER, ElementType.ANNOTATION_TYPE})public @interface PersonFrommId {}

Person实体类代码：

package com.nf147.manage.demo_fromatter;import java.util.Date;public class Person {    private String name;    private String province;    private Date birthday;    private String gender;    public Person() {    }    public Person(String province, Date birthday, String gender) {        this.province = province;        this.birthday = birthday;        this.gender = gender;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getProvince() {        return province;    }    public void setProvince(String province) {        this.province = province;    }    public Date getBirthday() {        return birthday;    }    public void setBirthday(Date birthday) {        this.birthday = birthday;    }    public String getGender() {        return gender;    }    public void setGender(String gender) {        this.gender = gender;    }}

Controller层代码：

package com.nf147.manage.controller;import com.nf147.manage.demo_fromatter.Person;import com.nf147.manage.demo_fromatter.PersonFrommId;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController;@RequestMapping("/ddd")@RestControllerpublic class DemoController {    @RequestMapping(method = RequestMethod.GET)    public Person home(@RequestParam(value = "id",required = false)@PersonFrommId Person person){        return person;    }}
