创建名称'entityManagerFactory'的bean时出错，javaxb或hibernate依赖关系未解决

我意识到在这里已经不停地被问到这个问题，但是在尝试从多个响应中修复之后，我仍然遇到这个问题。

尝试运行spring API时收到错误消息：

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 java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

这是我的pom文件。我尝试添加jaxb-api，hibernate-entitymanager，hibernate-core以及这三者的结合而没有运气。

这是我的模型课：

package com.max.rocketLeagueAPI.Models;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import java.sql.Timestamp;

@Entity
@Table(name = "cars")
public class Car {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "car_id")
    private int id;
    private String name;
    private String rarity;
    private String platform;
    @Column(name = "img_url")
    private String imgUrl;
    private boolean free;
    @Column(name = "updated_at")
    private Timestamp updatedAt;

    public Car() {}

    public int getId() {
        return this.id;
    }

    public String getName() {
        return this.name;
    }

    public String getRarity() {
        return this.rarity;
    }

    public String getPlatform() {
        return this.platform;
    }

    public String getImgUrl() {
        return this.imgUrl;
    }

    public boolean isFree() {
        return this.free;
    }

    public Timestamp getUpdatedAt() {
        return this.updatedAt;
    }
}

这是我要连接（或尝试连接）的表

mysql> describe cars;

和我的界面：

package com.max.rocketLeagueAPI.Repositories;

import com.max.rocketLeagueAPI.Models.Car;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface CarRepository extends JpaRepository<Car, Integer> {
    // car filters
    List<Car> findByPlatform(String platform);
    List<Car> findByRarity(String rarity);
    List<Car> findByFree(boolean isFree);
    List<Car> findByRarityAndFree(String rarity, boolean isFree);
}

和我的application.properties：

spring.datasource.url=jdbc:mysql://localhost:3306/rocketLeagueAPI
spring.datasource.username=max
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=update

我正在遵循有关编写spring api的指南，但是即使我使用了指南中的确切代码，也会遇到相同的错误。我所缺少的东西或注释不正确吗？

1 个答案:

答案 0 :(得分：1)

经过更多研究，我发现了问题并解决。 jdk11不再支持javaxb，因此需要添加以下依赖项：

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.2.11</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-core</artifactId>
    <version>2.2.11</version>
</dependency>
<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.11</version>
</dependency>
<dependency>
    <groupId>javax.activation</groupId>
    <artifactId>activation</artifactId>
    <version>1.1.1</version>
</dependency>

application.properties也需要：

spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=create

希望这可以帮助其他人解决此问题！
