针对SpringBoot服务端返回的空对象和空数组问题

返回的Json会自动过滤掉空指针的对象，但是若遇到非空指针的没有任何内容的对象，举例如下：

public class Person {
    private String name;
    private Integer age;
    private Boolean sex;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Boolean getSex() {
        return sex;
    }

    public void setSex(Boolean sex) {
        this.sex = sex;
    }
}

public class TestResponse extends DdxBaseResponse {

    private Person person;

    private List<Person> personList;

    public Person getPerson() {
        return person;
    }

    public void setPerson(Person person) {
        this.person = person;
    }

    public List<Person> getPersonList() {
        return personList;
    }

    public void setPersonList(List<Person> personList) {
        this.personList = personList;
    }
}

@RestController
public class TestController {

    @Autowired
    private ObjectMapper objectMapper;

//    @RsaToken
//    @Perm(1)
    @PostMapping("/test")
    public TestResponse go(@Validated @RequestBody TestRequest request) {
        TestResponse response = new TestResponse();
        return response;
    }

}

@RestController
public class TestController {

    @Autowired
    private ObjectMapper objectMapper;

//    @RsaToken
//    @Perm(1)
    @PostMapping("/test")
    public TestResponse go(@Validated @RequestBody TestRequest request) {
        TestResponse response = new TestResponse();
        response.setPerson(new Person()); //创建下，让其非空指针
        response.setPersonList(new ArrayList<>()); //创建下，让其非空指针
        return response;
    }

}
