Spring引导-实体到json-递归

我有相互双向映射的实体。调用REST Http.GET请求从db获取所有记录，由于无限递归，我收到StackOverflowException。我试图以不同的组合使用@JsonIgnore、@JsonBackReference、@JsonManageReference和@JsonIdentityInfo，但没有得到积极的结果。我仍然收到这个错误

Spring Boot在2.6.6版中加载了我的jackson

这是我的基本实体：

@MappedSuperclass
public class BaseEntity {
    @Id
    @GeneratedValue
    private Long id;
    private String createdBy;
    private Date createdOn;
    private String modifiedBy;
    private Date modifiedOn;
    public String description;

    public BaseEntity() {
    }

    public Long getId() {
        return id;
    }

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

    public String getCreatedBy() {
        return createdBy;
    }

    public void setCreatedBy(String createdBy) {
        this.createdBy = createdBy;
    }

    public Date getCreatedOn() {
        return createdOn;
    }

    public void setCreatedOn(Date createdOn) {
        this.createdOn = createdOn;
    }

    public String getModifiedBy() {
        return modifiedBy;
    }

    public void setModifiedBy(String modifiedBy) {
        this.modifiedBy = modifiedBy;
    }

    public Date getModifiedOn() {
        return modifiedOn;
    }

    public void setModifiedOn(Date modifiedOn) {
        this.modifiedOn = modifiedOn;
    }

    public String getDescription() {
        return description;
    }

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

第一类实体：

@Entity
public class Entry extends BaseEntity{

    private Date businessOperationDate;

    @ManyToOne
    private Version version;

    @ManyToOne
    private Status status;

    @ManyToOne
    @JsonManagedReference
    private Account account;

    public Entry() {
    }

    public Date getBusinessOperationDate() {
        return businessOperationDate;
    }

    public void setBusinessOperationDate(Date businessOperationDate) {
        this.businessOperationDate = businessOperationDate;
    }

    public Version getVersion() {
        return version;
    }

    public void setVersion(Version version) {
        this.version = version;
    }

    public Status getStatus() {
        return status;
    }

    public void setStatus(Status status) {
        this.status = status;
    }

    public Account getAccount() {
        return account;
    }

    public void setAccount(Account account) {
        this.account = account;
    }
}

第二个：

@Entity
public class Account extends BaseEntity{
    private String number;

    @OneToMany(mappedBy = "account", fetch = FetchType.EAGER)
    @JsonBackReference
    private List<Entry> entries;

    @ManyToMany(mappedBy = "accounts")
    private List<Project> projects;

    public Account() {
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public List<Entry> getEntries() {
        return entries;
    }

    public void setEntries(List<Entry> entries) {
        this.entries = entries;
    }

    public List<Project> getProjects() {
        return projects;
    }

    public void setProjects(List<Project> projects) {
        this.projects = projects;
    }
}

请告诉我，我做错了什么。我希望在结果中只接收一个级别，例如，调用getAll（）作为条目，我希望接收包含与帐户相关的信息的所有条目，反之，调用getAll（）作为帐户。

我搜索了更多次此错误，但是我可以遇到任何我得到的错误情况，我通过在一些关系映射中添加注释

@JsonIgnore

来纠正它

这就是一个例子

  @ManyToMany(mappedBy = "accounts")
    @JsonIgnore
    private List<Project> projects;

@ManyToMany（mappedBy=“accounts”）

请发布您的pom.xml，请从他们的文档中检查spring boot公共属性文件中的json响应。另外，您已经在pom.xml中为Jackson绑定错误添加了一个排除项。感谢您的支持。请发布您的pom.xml，请从他们的文档中检查spring boot公共属性文件中的json响应。另外，您已经在pom.xml中为Jackson绑定错误添加了一个排除项。谢谢你的支持。假设，我想从帐户中获取一个字段。我现在能做什么？好的。假设，我想从帐户中获取一个字段。我现在能做什么？
