Spring和Jackson：动态设置JSON忽略

我有一些JPA模型：“类别”和“文章”：

@Entity
@Table(name = "categories")
public class Category {
private int id;
private String caption;
private Category parent;
private List<Category> childrenList;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

@Column
public String getCaption() {
    return caption;
}

public void setCaption(String caption) {
    this.caption = caption;
}

@ManyToOne
@JoinColumn(name = "parent_id")
public Category getParent() {
    return parent;
}

public void setParent(Category parent) {
    this.parent = parent;
}

@OneToMany
@JoinColumn(name = "parent_id")
public List<Category> getChildrenList() {
    return childrenList;
}

public void setChildrenList(List<Category> childrenList) {
    this.childrenList = childrenList;
}
}



@Entity
@Table(name = "articles")
public class Article {
private int id;
private String caption;
private boolean isAvailable;
private String description;
private int price;
private Category category;

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}

@Column
public String getCaption() {
    return caption;
}

public void setCaption(String caption) {
    this.caption = caption;
}

@Column(name = "is_available")
@Type(type = "org.hibernate.type.NumericBooleanType")
public boolean getIsAvailable() {
    return isAvailable;
}

public void setIsAvailable(boolean available) {
    isAvailable = available;
}

@Column
public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

@Column
public int getPrice() {
    return price;
}

public void setPrice(int price) {
    this.price = price;
}

@ManyToOne
@JoinColumn(name = "category_id")
public Category getCategory() {
    return category;
}

public void setCategory(Category category) {
    this.category = category;
}
}

我也有一些具有两种方法的REST控制器：1）在第一种方法中，我需要获取并序列化最后10条文章，但在Categegory中不需要“ childrenList”和“ parent”字段。2）在第二种方法中，我需要获取相同的内容，但是序列化“ parent”字段。

我该如何解决？如果我将对这些字段使用@JsonIgnore批注，那么它们将永远不会序列化。还是我应该使用DTO类？

如何动态设置要忽略的字段？
