Spring Boot应用程序中的错误添加实体和休眠配置后无法启动tomcat

Question

Im getting below error after adding hibernate configuration to my app and not able to start server. I had created entitity classes.

In below screenshot you can see in left panel there is a PrimaryAccount class exist in com.userfront.domain package

Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled. 2017-11-18 20:56:32.700 ERROR 8408 --- [ main] osboot.SpringApplication : Application startup failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: @OneToOne or @ManyToOne on com.userfront.domain.PrimaryTransaction.PrimaryAccount references an unknown entity: com.userfront.domain.PrimaryAccount

i have below code in primaryAccount entity class.

    package com.userfront.domain;

    import java.math.BigDecimal;
    import java.util.List;

    import javax.persistence.CascadeType;
    import javax.persistence.FetchType;
    import javax.persistence.GeneratedValue;
    import javax.persistence.GenerationType;
    import javax.persistence.Id;
    import javax.persistence.OneToMany;

    import com.fasterxml.jackson.annotation.JsonIgnore;

    public class PrimaryAccount {
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        private Long id;
        private int accountNumber;
        private BigDecimal accountBalance;

        @OneToMany(mappedBy ="primaryAccount", cascade=CascadeType.ALL, fetch = FetchType.LAZY)
        @JsonIgnore
        private List<PrimaryTransaction> primaryTransaction;

        public Long getId() {
            return id;
        }

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

        public int getAccountNumber() {
            return accountNumber;
        }

        public void setAccountNumber(int accountNumber) {
            this.accountNumber = accountNumber;
        }

        public BigDecimal getAccountBalance() {
            return accountBalance;
        }

        public void setAccountBalance(BigDecimal accountBalance) {
            this.accountBalance = accountBalance;
        }

        public List<PrimaryTransaction> getPrimaryTransaction() {
            return primaryTransaction;
        }

        public void setPrimaryTransaction(List<PrimaryTransaction> primaryTransaction) {
            this.primaryTransaction = primaryTransaction;
        }

    }

Help me out in fixing this.

Edited: I have updated PrimaryAccount class with @Entity annotation, still im having below error

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property: com.userfront.domain.PrimaryTransaction.primaryAccount in com.userfront.domain.PrimaryAccount.primaryTransaction

PrimaryTransaction.java

package com.userfront.domain;

import java.math.BigDecimal;
import java.util.Date;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;

@Entity
public class PrimaryTransaction {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private Date date;
    private String description;
    private String type;
    private String status;
    private double amount;
    private BigDecimal availableBalance;

    @ManyToOne
    @JoinColumn(name = "primary_account_id")
    private PrimaryAccount PrimaryAccount;

    public PrimaryTransaction() {  }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public String getDescription() {
        return description;
    }

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

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getStatus() {
        return status;
    }

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

    public double getAmount() {
        return amount;
    }

    public void setAmount(double amount) {
        this.amount = amount;
    }

    public BigDecimal getAvailableBalance() {
        return availableBalance;
    }

    public void setAvailableBalance(BigDecimal availableBalance) {
        this.availableBalance = availableBalance;
    }
}

2nd Edit: Corrected PrimaryAccount class where 'primaryTransaction' was to there to 'PrimaryTransaction' which is class name.

@Entity
public class PrimaryAccount {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;
    private int accountNumber;
    private BigDecimal accountBalance;

    @OneToMany(mappedBy ="PrimaryAccount", cascade=CascadeType.ALL, fetch = FetchType.LAZY)
    @JsonIgnore
    private List<PrimaryTransaction> PrimaryTransaction;

Answer 1

You've not mapped Entity Types correctly in your User entity, you should add Associations mapping to it:

@Entity
public class User {

    ...

    @ManyToOne
    private PrimaryAccount primaryAccount;

    @ManyToOne
    private SavingsAccount savingsAccount;

    @OneToMany(mappedBy="user")
    private List<Appointment> appointmentList;

    @OneToMany // you may add [mappedBy] if it's bidirectional
    private List<Recipient> recipientList;

    ...
}

To avoid this kind of mapping exception, annotate all fields explicitly, and do not let the ORM use the default mapping.

Note:

I've spotted a potential StackOverflowError while looking to User.toString() and Appointment.toString() , as both will call each other infinitely:

Appointment.toString() {...+ ", appointmentList=" + appointmentList...}` 

User.toString() {...", user=" + user + "]"...}

You should get rid one of them.

Answer 2

PrimaryAccount class is not annotated with @Entity annotation. That might be the issue.

Try

 @Entity
 public class PrimaryAccount {

In the Primary account class mappedBy = primaryAccount But the variable name in PrimaryTransaction class is PrimaryTransaction ie a capital P change it to small case such that it matches

that should solve

nested exception is org.hibernate.AnnotationException: mappedBy reference an unknown target entity property:

public class PrimaryAccount {

    @OneToMany(mappedBy ="**primaryAccount**", cascade=CascadeType.ALL, fetch = FetchType.LAZY)
    @JsonIgnore
    private List<PrimaryTransaction> primaryTransaction;
