클래스 경로 자원에 정의 된 이름이 'entityManagerFactory'인 Bean 작성 오류 : init 메소드 호출 실패 -> </parent>

봄 프로젝트를 컴파일 할 때 다음과 같은 오류가 발생했습니다.

클래스 경로 리소스 [org / springframework / boot / autoconfigure / orm / jpa / HibernateJpaAutoConfiguration.class]에 정의 된 이름이 ‘entityManagerFactory’인 Bean 생성 오류 : init 메소드 호출 실패

STS Eclipse 및 MySql 데이터베이스를 사용하고 있습니다.

내 연결 문자열 Application.Properties은

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

자세한 오류는 다음과 같습니다.

답변

다음 종속성을 추가하여 시작합니다.

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>4.1.4.Final</version>
</dependency>

과

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>5.2.3.Final</version>
</dependency>

업데이트 : 또는 간단히 다음 종속성을 추가하십시오.

<dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
</dependency>

답변

Java 9를 사용하는 사람들은 다음 종속성을 포함합니다.

<dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
</dependency>

답변

종속성을 추가해도 문제가 해결되지 않았습니다.

이 문제는 “@Entity”클래스의 일부이고 데이터베이스에 존재하지 않는 “추가”필드로 인해 제 끝에서 발생했습니다.

@Entity 클래스에서 추가 필드를 제거하고 작동했습니다.

행운을 빕니다.

답변

나도 같은 문제에 직면했습니다. Java9를 사용하고 pom 파일에서 다음 종속성을 사용했습니다.

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-jdbc</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>

        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

이 문제는 pom에 아래 종속성을 추가 한 후 해결되었습니다.

    <dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.3.0</version>
    </dependency>

답변

의 jar 파일 hibernate-core과hibernate-entitymanager 종속성이 손상되었거나 컴퓨터에 제대로 설치되지 않은 것 같습니다.

나는 방금 제안 라는 이름의 폴더를 삭제 hibernate-core하고 hibernate-entitymanager메이븐 로컬 저장소에서을 메이븐이 다시 설치됩니다.

Maven 로컬 저장소의 기본 위치 C:\Documents and Settings\[USERNAME]\.m2는 Windows 또는 ~/.m2Linux / Mac입니다.

답변

제 경우에는 아래 주석 중 하나를 삭제하면 예를 들어 ‘entityManagerFactory’오류 메시지가 표시됩니다.

 @Id
  @GeneratedValue(strategy=GenerationType.AUTO)

또는

@ManyToMany(targetEntity=listOfObject_x.class)

누락 된 주석을 추가하면 오류 메시지가 사라집니다.

package mypackage_unameit;
import javax.persistence.PrePersist;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;

import lombok.Data;

@Data
@Entity
public class Someclasss {

  @Id
  @GeneratedValue(strategy=GenerationType.AUTO)
  private Long id;

  @NotNull
  @Size(min=5, message="Name must be at least 5 characters long")
  private String name;

  private Date createdAt;

  @ManyToMany(targetEntity=listOfObject_x.class)
  @Size(min=1, message="You must choose at least 1 ingredient")
  private List<listOfObject_x>   = new ArrayList<>();

  @PrePersist
  void createdAt() {
    this.createdAt = new Date();
  }
}

답변

나는 jdk-12.0.2.jdk, ‘문제에 대한 해결책을 찾았고 pom.xml에 종속성을 추가했습니다.
