老师您好！
在视频9-4和9-5 activiti工作流搭建集成springboot 中，在整合activiti-ui中，出现视频之外的启动问题
将视频中的需要修改的地方修改后

1.查看了您回答某位某位同学的问题，添加了该注解
https://coding.imooc.com/learn/questiondetail/64432.html

@Import({ApplicationConfiguration.class})
@EntityScan({ "org.activiti.app.domain" })
@SpringBootApplication
public class ActivitiUIApplication extends SpringBootServletInitializer {
}

2. 并且禁用了hibernate的二级缓存

spring:
  freemarker:
    check-template-location: false
  jpa:
    properties:
      hibernate:
        cache:
          use_second_level_cache: fasle

3.根据stackoverflow.的意见修改了源码
https://stackoverflow.com/questions/29715863/spring-boot-rest-app-on-gae-throws-an-exception-cannot-be-cast-to-javax-persiste

  @Bean(name = "transactionManager")
  public PlatformTransactionManager annotationDrivenTransactionManager() {
    JpaTransactionManager jpaTransactionManager = new JpaTransactionManager();
    // 这里改变代码 =》 entityManagerFactory().getObject()
    jpaTransactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
    return jpaTransactionManager;
  }
  @Bean(name = "entityManagerFactory")
  public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    log.info("Configuring EntityManager");
    LocalContainerEntityManagerFactoryBean lcemfb = new LocalContainerEntityManagerFactoryBean();
    lcemfb.setPersistenceProvider(new HibernatePersistence());
    lcemfb.setPersistenceUnitName("persistenceUnit");
    lcemfb.setDataSource(dataSource());
    lcemfb.setJpaDialect(new HibernateJpaDialect());
    lcemfb.setJpaVendorAdapter(jpaVendorAdapter());

    Properties jpaProperties = new Properties();
    jpaProperties.put("hibernate.cache.use_second_level_cache", false);
    jpaProperties.put("hibernate.generate_statistics", env.getProperty("hibernate.generate_statistics", Boolean.class, false));
    lcemfb.setJpaProperties(jpaProperties);

    lcemfb.setPackagesToScan("org.activiti.app.domain");
    lcemfb.afterPropertiesSet();
    // 这里改变了返回类型
    return lcemfb;
  }

程序启动仍然报错（只展示一部分错误信息）：

我看了下问答，有很多学员在这部分和我一样遇到了这些问题，但是教学视频中似乎没有提到，我按照有些学院提供的解决方案，但是不起效果，老师这个报错要如何解决？
