java - 我可以在 Spring Boot 中为函数添加 "get"前缀吗

Question

我有一个与 MongoRepository 关联的 Mcq 类，我想获取一个应用了多项更改的 Mcq 实例(答案随机播放、问题绘制等)。我声明了我的函数“myMcq.getInstance()”，但我不能这样做，因为每次我想在 ResponseEntity 中发送 Mcq 时，JSON 输出中都会出现错误，因为 Springboot 认为我的类中有一个“instance”属性。

这是我的 java 类:

@Document(collection = "Mcqs")
public class Mcq {
    @Id public String id;
    @DBRef public User creator;

    public String title;
    public String categoryID;
    public List<McqChapter> chapterList = new ArrayList<>();
    public Difficulty difficulty;

    public Mcq() {}

    public Mcq(String title) {
        this();
        this.title = title;
    }

    public ArrayList<String> getQuestionsIDs() {
        ArrayList<String> result = new ArrayList<>();

        for (McqChapter chapter : chapterList) result.addAll(chapter.getQuestionIDs());

        return result;
    }


    public McqInstance getInstance() {
        return new McqInstance(this);
    }
}

Answer 1

为了防止错误添加 @JsonIgnore到 getInstance() 方法:

@JsonIgnore 
public McqInstance getInstance() {
    return new McqInstance(this);
}

Marker annotation that indicates that the annotated method or field is to be ignored by introspection-based serialization and deserialization functionality. That is, it should not be consider a "getter", "setter" or "creator".
