我刚穿春靴。我想用mysql、hibernate、jpa和JSP配置spring boot。当我想启动它时,我出现了一个错误:“Error creating bean with name'session factory'等”,更多信息请参见StackTrace:

首先使用框架,而不是围绕框架工作。您还声明希望使用Spring Boot和JPA,但您的配置显示您正在非常努力地不使用Spring Boot,并且您不使用JPA,而是使用普通的Hibernate。

首先删除databaseconfig。(是的,移除它)。

HomeBudgetApplication移动到com.bugdet并删除所有注释,替换为一个简单的@SpringBootApplication

@SpringBootApplication
public class HomeBudgetApplication {

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

application.properties中添加spring.mvc.view属性,以自动配置InternalResourceViewResolver。同时删除已为您添加的EntityManager.Packages.To.Scan

spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/budget
spring.datasource.username=marcin
spring.datasource.password=marcin123
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

其他的一切都将由Spring Boot配置。它将检测您的web、jpa和事务,并自动对其进行配置。

如果您有任何基于SessionFactory的存储库等,请将其替换为在EntityManager上工作。
