类人：

@Data
public class Person<T extends Parent> implements Serializable {
    private static final long serialVersionUID = 7822965786010192978L;

    private static final ObjectMapper objectMapper = new ObjectMapper();  
    private String id;    
    private T people; // change (String peopleInfo) to object extends Parent after read data from database
    private String peopleInfo; // change (T people) to string and save in the dataBase as an string

    @SneakyThrows
    public void setPeople(T people) {
        this.people = people;
        peopleInfo = objectMapper.writeValueAsString(people);
    }

    @SneakyThrows
    public void setPeopleInfo(String peopleInfo) { …

在 Vue 组件中：

import { someRequestMethod } from '@/api/requ'

...

methods: {
    testMethod() {
        someRequestMethod(someRequestData).then(function() {
            this.outMethod_01()
        }).then(function() {
            this.outMethod_02()
        })
    }

    outMethod_01() {
        console.log('I am an outer method 01.');
    }

    outMethod_02() {
        console.log('I am an outer method 02.');
    }
}

当我打电话时testMethod，有Promise回应。然后我想调用outMethod_01如果成功，outMethod_02如果有错误。但我有错误outMethod_01 is undefined和outMethod_02 is undefined。

那么如何调用外部方法Promise呢？
