在 Spring Data Jpa 中获取 OneToMany 映射实体时出现 StackOverflowError
StackOverflowError while fetching OneToMany mapped entity in Spring Data Jpa
我有两个具有双向映射的实体。实体如下，
**Entity 1**
@Entity
@Table(name = "Customer")
public class CustomerEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The first name. */
@Column(name = "FirstName", length = 60, nullable = false)
private String firstName;
/** The last name. */
@Column(name = "LastName", length = 60, nullable = false)
private String lastName;
/** The dob. */
@Column(name = "DOB", nullable = false)
private LocalDate dob;
/** The mobile number. */
@Column(name = "MobileNumber", length = 10, nullable = false, unique = true)
private Long mobileNumber;
/** The email id. */
@Column(name = "Email", length = 100, nullable = false, unique = true)
private String emailId;
/** The address. */
@Column(name = "Address", length = 255)
private String address;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The accounts. */
@OneToMany(mappedBy = "customerEntity", cascade = CascadeType.ALL)
private List<AccountEntity> accountEntities = new ArrayList<>();
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "CustomerEntity [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", dob=" + dob
+ ", mobileNumber=" + mobileNumber + ", emailId=" + emailId + ", address=" + address + ", createdTime="
+ createdTime + ", accountEntities=" + accountEntities + "]";
}
}
**Entity 2**
@Entity
@Table(name = "Account")
public class AccountEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The account number. */
@Column(name = "AccountNumber", length = 20, nullable = false, unique = true)
private String accountNumber;
/** The branch. */
@Column(name = "Branch", nullable = false)
private String branch;
/** The account type. */
@Column(name = "AccountType", nullable = false)
private String accountType;
/** The balance. */
@Column(name = "Balance", nullable = false)
private Double balance;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The account holder. */
@ManyToOne(fetch = FetchType.LAZY)
private CustomerEntity customerEntity;
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntity="
+ customerEntity + "]";
}
}
我需要获取所有客户实体及其映射帐户。我的服务代码是这样的，
public Set<CustomerDTO> fetchCustomers(String searchKey) {
List<CustomerEntity> customers = null;
if (searchKey == null || searchKey.trim().isEmpty()) {
**customers = customerRepository.findAll();**
} else {
**customers = customerRepository.findByFirstNameContainingIgnoreCaseOrLastNameContainingIgnoreCase(searchKey,
searchKey);**
}
System.out.println(customers);
return customers.stream()
.map(entity -> new CustomerDTO(entity.getId(), entity.getFirstName(), entity.getLastName(),
entity.getDob(), entity.getEmailId(), entity.getMobileNumber(), entity.getAddress(),
entity.getCreatedTime()))
.collect(Collectors.toSet());
}
但我收到 WhosebugError。日志如下所述，

有人能帮忙吗？？我在这里错过了什么？
更新
toString() 和日志已更新。由于大小限制，无法添加完整日志。
于 AccountEntity.class
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntity="
+ customerEntity + "]";
}
你的 toString() 包括 customerEntity 但在 CustomerEntity.class 中还有一个字段 accountEntities<AccountEntity>.
所以你的 .toString() 方法得到了 .toString() 的递归调用，这最终导致了 Whosebug 错误。
AccountEntity.class 上的 IMO .toString() 应该是
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntityId="
+ customerEntity.getId() + "]";
}
您的 accountEntity 似乎存在循环依赖问题。
如果您创建数组列表的新实例，建议您在 Lombok 中添加 @Singular。
@Singular
private List<AccountEntity> accountEntities = new ArrayList<>();
您也可以尝试从 toString 中删除 AccountEntity 以防止循环依赖。或者通过使用 Lombok 使用：
@toString (exclude = "accountEntities")
阅读此处：
你需要在实体的映射关系上方添加@JsonIgnore，因为调用时映射会做递归映射
@Entity
@Table(name = "Account")
public class AccountEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The account number. */
@Column(name = "AccountNumber", length = 20, nullable = false, unique = true)
private String accountNumber;
/** The branch. */
@Column(name = "Branch", nullable = false)
private String branch;
/** The account type. */
@Column(name = "AccountType", nullable = false)
private String accountType;
/** The balance. */
@Column(name = "Balance", nullable = false)
private Double balance;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The account holder. */
@ManyToOne(fetch = FetchType.LAZY)
@JsonIgnore
private CustomerEntity customerEntity;
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntity="
+ customerEntity + "]";
}
}
或者你可以在这里使用@JsonIgnore
@Entity
@Table(name = "Customer")
public class CustomerEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The first name. */
@Column(name = "FirstName", length = 60, nullable = false)
private String firstName;
/** The last name. */
@Column(name = "LastName", length = 60, nullable = false)
private String lastName;
/** The dob. */
@Column(name = "DOB", nullable = false)
private LocalDate dob;
/** The mobile number. */
@Column(name = "MobileNumber", length = 10, nullable = false, unique = true)
private Long mobileNumber;
/** The email id. */
@Column(name = "Email", length = 100, nullable = false, unique = true)
private String emailId;
/** The address. */
@Column(name = "Address", length = 255)
private String address;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The accounts. */
@OneToMany(mappedBy = "customerEntity", cascade = CascadeType.ALL)
private List<AccountEntity> accountEntities = new ArrayList<>();
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "CustomerEntity [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", dob=" + dob
+ ", mobileNumber=" + mobileNumber + ", emailId=" + emailId + ", address=" + address + ", createdTime="
+ createdTime + ", accountEntities=" + accountEntities + "]";
}
}
我有两个具有双向映射的实体。实体如下，
**Entity 1**
@Entity
@Table(name = "Customer")
public class CustomerEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The first name. */
@Column(name = "FirstName", length = 60, nullable = false)
private String firstName;
/** The last name. */
@Column(name = "LastName", length = 60, nullable = false)
private String lastName;
/** The dob. */
@Column(name = "DOB", nullable = false)
private LocalDate dob;
/** The mobile number. */
@Column(name = "MobileNumber", length = 10, nullable = false, unique = true)
private Long mobileNumber;
/** The email id. */
@Column(name = "Email", length = 100, nullable = false, unique = true)
private String emailId;
/** The address. */
@Column(name = "Address", length = 255)
private String address;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The accounts. */
@OneToMany(mappedBy = "customerEntity", cascade = CascadeType.ALL)
private List<AccountEntity> accountEntities = new ArrayList<>();
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "CustomerEntity [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", dob=" + dob
+ ", mobileNumber=" + mobileNumber + ", emailId=" + emailId + ", address=" + address + ", createdTime="
+ createdTime + ", accountEntities=" + accountEntities + "]";
}
}
**Entity 2**
@Entity
@Table(name = "Account")
public class AccountEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The account number. */
@Column(name = "AccountNumber", length = 20, nullable = false, unique = true)
private String accountNumber;
/** The branch. */
@Column(name = "Branch", nullable = false)
private String branch;
/** The account type. */
@Column(name = "AccountType", nullable = false)
private String accountType;
/** The balance. */
@Column(name = "Balance", nullable = false)
private Double balance;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The account holder. */
@ManyToOne(fetch = FetchType.LAZY)
private CustomerEntity customerEntity;
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntity="
+ customerEntity + "]";
}
}
我需要获取所有客户实体及其映射帐户。我的服务代码是这样的，
public Set<CustomerDTO> fetchCustomers(String searchKey) {
List<CustomerEntity> customers = null;
if (searchKey == null || searchKey.trim().isEmpty()) {
**customers = customerRepository.findAll();**
} else {
**customers = customerRepository.findByFirstNameContainingIgnoreCaseOrLastNameContainingIgnoreCase(searchKey,
searchKey);**
}
System.out.println(customers);
return customers.stream()
.map(entity -> new CustomerDTO(entity.getId(), entity.getFirstName(), entity.getLastName(),
entity.getDob(), entity.getEmailId(), entity.getMobileNumber(), entity.getAddress(),
entity.getCreatedTime()))
.collect(Collectors.toSet());
}
但我收到 WhosebugError。日志如下所述，

有人能帮忙吗？？我在这里错过了什么？
更新 toString() 和日志已更新。由于大小限制，无法添加完整日志。
于 AccountEntity.class
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntity="
+ customerEntity + "]";
}
你的 toString() 包括 customerEntity 但在 CustomerEntity.class 中还有一个字段 accountEntities<AccountEntity>.
所以你的 .toString() 方法得到了 .toString() 的递归调用，这最终导致了 Whosebug 错误。
AccountEntity.class 上的 IMO .toString() 应该是
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntityId="
+ customerEntity.getId() + "]";
}
您的 accountEntity 似乎存在循环依赖问题。
如果您创建数组列表的新实例，建议您在 Lombok 中添加 @Singular。
@Singular
private List<AccountEntity> accountEntities = new ArrayList<>();
您也可以尝试从 toString 中删除 AccountEntity 以防止循环依赖。或者通过使用 Lombok 使用：
@toString (exclude = "accountEntities")
阅读此处：
你需要在实体的映射关系上方添加@JsonIgnore，因为调用时映射会做递归映射
@Entity
@Table(name = "Account")
public class AccountEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The account number. */
@Column(name = "AccountNumber", length = 20, nullable = false, unique = true)
private String accountNumber;
/** The branch. */
@Column(name = "Branch", nullable = false)
private String branch;
/** The account type. */
@Column(name = "AccountType", nullable = false)
private String accountType;
/** The balance. */
@Column(name = "Balance", nullable = false)
private Double balance;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The account holder. */
@ManyToOne(fetch = FetchType.LAZY)
@JsonIgnore
private CustomerEntity customerEntity;
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "AccountEntity [id=" + id + ", accountNumber=" + accountNumber + ", branch=" + branch + ", accountType="
+ accountType + ", balance=" + balance + ", createdTime=" + createdTime + ", customerEntity="
+ customerEntity + "]";
}
}
或者你可以在这里使用@JsonIgnore
@Entity
@Table(name = "Customer")
public class CustomerEntity implements Serializable {
/** The Constant serialVersionUID. */
private static final long serialVersionUID = 1L;
/** The id. */
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
/** The first name. */
@Column(name = "FirstName", length = 60, nullable = false)
private String firstName;
/** The last name. */
@Column(name = "LastName", length = 60, nullable = false)
private String lastName;
/** The dob. */
@Column(name = "DOB", nullable = false)
private LocalDate dob;
/** The mobile number. */
@Column(name = "MobileNumber", length = 10, nullable = false, unique = true)
private Long mobileNumber;
/** The email id. */
@Column(name = "Email", length = 100, nullable = false, unique = true)
private String emailId;
/** The address. */
@Column(name = "Address", length = 255)
private String address;
/** The created time. */
@Column(name = "CreatedTime", nullable = false)
private LocalDateTime createdTime;
/** The accounts. */
@OneToMany(mappedBy = "customerEntity", cascade = CascadeType.ALL)
private List<AccountEntity> accountEntities = new ArrayList<>();
// Constructors, getters, setters, hashcode, equals, and toString methods are here
@Override
public String toString() {
return "CustomerEntity [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + ", dob=" + dob
+ ", mobileNumber=" + mobileNumber + ", emailId=" + emailId + ", address=" + address + ", createdTime="
+ createdTime + ", accountEntities=" + accountEntities + "]";
}
}
