我在 IntelliJ 中创建了一个 spring boot 项目，并且在构建时出现以下错误。

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.actuate.autoconfigure.metrics.orm.jpa.HibernateMetricsAutoConfiguration': Injection of autowired dependencies failed; nested exception is java.lang.IllegalStateException: Failed to asynchronously initialize native EntityManagerFactory: java.lang.NullPointerException

我在项目中创建的控制器文件

package in.osm.application;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

表 Sample 的域类 1

package in.osm.application.domain;

import com.sun.javafx.beans.IDProperty;
import lombok.*;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

import javax.persistence.*;
import java.io.Serializable;
import java.time.Instant;
import java.util.List;

@Entity
@NoArgsConstructor
@AllArgsConstructor
@Builder(toBuilder = true)
@Data
public class Sample implements Serializable {

    private String Id;
    @Id
    private int PartId;
    @OneToMany( fetch = FetchType.LAZY,mappedBy = "sParts", cascade = CascadeType.ALL)
    private List<SampleLine> sampleLine;
    @Enumerated(EnumType.STRING)
    private Type type;
      


}

表 SampleLine 的域类 2

package in.osm.application.domain;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.hibernate.criterion.Order;

import javax.persistence.*;
import java.time.Instant;

@Entity
@AllArgsConstructor
@NoArgsConstructor
@Builder(toBuilder = true)
@Data
public class SampleLine {

    @Id
    private String SampleLineId;
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name="sample_part_id")
    private Sample sParts;
    

}

表示例的存储库

package in.osm.application.repository;

import in.app.app.domain.Sample;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface SampleRepository extends JpaRepository<Sample,Integer> {

当我不添加存储库类时，代码工作正常。有人可以帮忙解决这个错误吗？

空数据库创建-删除选项没有遇到同样的问题。我想您的问题是数据库用户没有足够的权限来读取数据库元数据。

您可以在 docker 中使用本地数据库进行测试：

docker run --name postgres -e POSTGRES_PASSWORD=passd -P -d postgres

spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.datasource.url=jdbc:postgresql://localhost:<port>/postgres
spring.datasource.username=postgres
spring.datasource.password=passd
spring.jpa.show-sql=true
spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=create-drop

You need to upgrade your swagger springfox to latest version i.e. 3.0.0

Older version is not compatilble with Spring-Boot 2.2 and obove.
Replace your dependecies springfox-swagger2 and springfox-swagger-ui to springfox-boot-starter

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-boot-starter</artifactId>
    <version>3.0.0</version>
</dependency>
