Spring错误：org.springframework.beans.factory.BeanCreationException：创建名为'entityManagerFactory'的bean在URL

Question

我学春天，我有一个问题：

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in URL [file:/C:/Users/PanTau_acc/Desktop/SPRING/target/classes/applicationContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: com.donutek] Unable to build Hibernate SessionFactory

Caused by: javax.persistence.PersistenceException: [PersistenceUnit: com.donutek] Unable to build Hibernate SessionFactory

当我使用我的实体LoginLog运行项目时。

  import java.io.Serializable;
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Table;


@Entity
@Table(name = "login_log")
public class LoginLog extends BaseObject implements Serializable {

    private Date date;
    private String ip;
    private User user;

    public LoginLog() {
        //
    }

    public LoginLog(Date date, String ip, User user) {
        this.date = date;
        this.ip = ip;
        this.user = user;
    }

    public Date getDate() {
        return date;
    }

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

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

}

Base object is:

    @MappedSuperclass
public class BaseObject {

    private Long id;

    /**
     *
     * @return true if the entity hasn't been persisted yet
     */
    @Transient
    public boolean isNew() {
        return id == null;
    }

    @Id
    @GeneratedValue
    public Long getId() {
        return id;
    }

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

applicationContext.xml是：

    <?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <property name="packagesToScan" value="com.donutek.**.domain"/>
        <property name="persistenceUnitName" value="com.donutek"/>
    </bean>

    <bean id="hibernateVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter"/>

    <!-- Transaction manager for a single EntityManagerFactory (alternative to JTA) -->
    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory"/>
    </bean>
</beans>

我认为，问题出在public LoginLog(Date date, String ip, User user)，因为当我在User user课程中运行没有LoginLog的代码时，它正常工作。

你能帮助我吗？

感谢您的建议。

Spring版本是：4.2.4.RELEASE

修改 user.java是：

import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name = "user")
public class User extends BaseObject {

    /**
     * Login, unique
     */
    private String email;
    /**
     * Secret for signing-in
     */
    private String password;
    /**
     * Date of user registration
     */
    private Date dateRegistration;
    /**
     * User nick name
     */
    private String nickName;
    /**
     * State of user accoutn
     */
    private UserState userAccState;

    public User() {
        //
    }

    public User(String email, String password, String nickName) {
        this.email = email;
        this.password = password;
        this.dateRegistration = new Date();
        this.nickName = nickName;
        this.userAccState = UserState.acc_waitingForActivated;
    }

    @Column(unique = true)
    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public Date getDateRegistration() {
        return dateRegistration;
    }

    public void setDateRegistration(Date dateRegistration) {
        this.dateRegistration = dateRegistration;
    }

    public String getNickName() {
        return nickName;
    }

    public void setNickName(String nickName) {
        this.nickName = nickName;
    }

    public UserState getUserAccState() {
        return userAccState;
    }

    public void setUserAccState(UserState userAccState) {
        this.userAccState = userAccState;
    }

}

Answer 1

为LoginLog类中的User对象提供hibernate映射：

示例：

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "email", nullable = false)
    public User getUser() {
        return user;
    }
