设置构造函数参数时无法解析对bean'entityManagerFactory'的引用

Question

我刚刚迁移到spring JPA技术，并设法将我的简单jersey hibernate项目更改为具有自定义crudrepository的spring JPA。但我不能处理自动配置EntityManagerFactorybean。下面是我的代码：

application.properties：

spring.datasource.url = jdbc:mysql://79.175.138.59:13306/testdatabase2?createDatabaseIfNotExist=true&autoReconnect=true&useUnicode=true&connectionCollation=utf8_general_ci&characterSetResults=utf8&characterEncoding=utf-8
spring.datasource.username = root
spring.datasource.password = password
spring.jpa.hibernate.ddl-auto = update
spring.jpa.generate-ddl = true
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.jpa.show-sql = true

应用程序：

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

错误日志报告：

@Transactional
public interface ErrorLogRepo extends CrudRepository<ErrorLog, Long>{
public Iterable<ErrorLog>  findByDateBetweenAndLogType(long from, long to, String logType);
}

LogHandler：

@Service
public class LogHandler {
@Autowired
private ErrorLogRepo errorLogRepo;
...}

错误日志：

@Entity
@Table(name= "ErrorLog")
public class ErrorLog {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;

private String logText;
...//setter and getters}

谢谢你的建议谢谢

Answer 1

如果您使用的是Hibernate，那么必须提供称为EntityManagerFactory的最基本的Hibernate对象（或spring中的bean）来管理db会话。这可能很有帮助：在Spring Hibernate配置中获取EntityManager

Answer 2

异常表示没有名为entityManagerFactory的bean，请在

public LocalContainerEntityManagerFactoryBean entityManagerFactory(
            EntityManagerFactoryBuilder factoryBuilder)

方法org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.class并检查为什么bean没有被启动。

哦，从讨论中我得出结论，提到的问题是由于Hibernate较旧的依赖关系造成的。此外，导入的@Id需要来自javax。坚持不懈所有实体的id。
