这是你的内容的翻译:

错误1 - 使用 @EntityScan 注解的详细错误日志

org.springframework.beans.factory.BeanCreationException: 在类路径资源 [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class] 中定义的名为 'entityManagerFactory' 的 bean 创建失败:初始化方法调用失败;嵌套异常是 javax.persistence.PersistenceException: [PersistenceUnit: default] 无法构建 Hibernate SessionFactory
    ...

错误2 - 未使用 @EntityScan 注解的详细错误日志

org.springframework.dao.InvalidDataAccessApiUsageException: 未知实体:model.Owner;嵌套异常是 java.lang.IllegalArgumentException: 未知实体:model.Owner
    ...

英文:

I'm newbie on Spring Boot and I want to make a rest webservice with spring boot. I need to persist some data on database using Jpa/Hibernate. When I annotate my domain model class with @Entity annotation and I start my application as Spring boot application (My application class have an @EntityScan() annotation by the way.) I am getting error below :

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

When I don't annotate my application class with @EntityScan annotation and run my app and call my rest controller method of createOwner() , I am getting error below :

org.springframework.dao.InvalidDataAccessApiUsageException: Unknown entity: model.Owner; nested exception is java.lang.IllegalArgumentException: Unknown entity: model.Owner

I'll be happy if you inform me about why I'm getting these errors, thanks.

My classes are :

Domain Class :

Owner.java

@Entity
public class Owner {
	
	@Id
	@GeneratedValue(strategy=GenerationType.AUTO)
	private Long id;
	private String firstName;
	private String lastName;

	public Owner() {}


	public Long getId() {
		return id;
	}

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

	public String getFirstName() {
		return firstName;
	}

	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}

	public String getLastName() {
		return lastName;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;
	}
}

Application Class :

@SpringBootApplication(scanBasePackages={"web","service","dao"})
@EntityScan(basePackages= {"model"})
@EnableConfigurationProperties(value = PetClinicProperties.class)
public class PetClinic {

	public static void main(String[] args) {

		
		SpringApplication.run(PetClinic.class, args);

	}
}

Controller Class :

@RestController
@Transactional
public class PetClinicControl {

@Autowired
private PetClinicService petClinicService;


public void setPetClinicService(PetClinicService petClinicService) {
	this.petClinicService = petClinicService;
}

@RequestMapping(method=RequestMethod.POST,value="/createOwner")
public ResponseEntity<Owner> createOwner(@RequestBody Owner owner){
	
	try {
		
		Owner ownerNew = new Owner();
		ownerNew.setId(owner.getId());
		ownerNew.setFirstName(owner.getFirstName());
		ownerNew.setLastName(owner.getLastName());
		
		petClinicService.createOwner(ownerNew);
		
		return ResponseEntity.ok(ownerNew);
		
	}catch(Exception ex) {
		
		ex.printStackTrace();
		return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
     }
   }	
 }

My application.properties :

management.endpoints.enabled-by-default=true
management.endpoints.web.exposure.include=*

spring.datasource.driverClassName=org.h2.Driver
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.username=sa
spring.datasource.password=123456

server.port=8095

通过在我的OpenJDK 15上使用最新的Javassist解决了这个问题。
我添加了以下依赖项到我的pom.xml文件中:

<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.27.0-GA</version>
</dependency>
英文:

by using the latest javassit on my openjdk15 solved the issue
I added this

&lt;dependency&gt;
&lt;groupId&gt;org.javassist&lt;/groupId&gt;
&lt;artifactId&gt;javassist&lt;/artifactId&gt;
&lt;version&gt;3.27.0-GA&lt;/version&gt;
&lt;/dependency&gt;

maven dependency in my pom.xml

似乎我修复了第一种错误(在使用@EntityScan时出现的错误),其中有一行是:

> 无法调用“java.lang.reflect.AccessibleObject.setAccessible(boolean),因为“ao”为空”

我通过将Hibernate的字节码提供程序从javassist替换为bytebuddy来修复了这个错误(在hibernate.properties文件中添加了hibernate.bytecode.provider=bytebuddy属性)。

英文:

It seems I fixed the first kind of error (using @EntityScan, when there is

> Cannot invoke "java.lang.reflect.AccessibleObject.setAccessible(boolean) because "ao" is null"

by replacing hibernate's bytecode provider from javassist to bytebuddy (placed hibernate.bytecode.provider=bytebuddy property to hibernate.properties file).

将以下内容添加到您的Application类中:@EntityScan(basePackages = "io.summer")。这对于Hibernate扫描您的实体是必需的。(对于我来说有效,针对PostgreSQL)

英文:

Adding @EntityScan(basePackages = "io.summer") to your Application class. That is needed for hibernate to scan your entities. (Worked for me, for postgresql)
