我正在将SpringBoot应用程序从1.5.6.release更新到2.3.5，但在生成项目时出现异常。下面是我的错误类：

@Configuration
@EnableBatchProcessing
@Import({BatchScheduler.class})
public class MyLogBatchConfiguration {
  private static final Logger log = LoggerFactory.getLogger(VToolLogBatchConfiguration.class);
  @Autowired private SimpleJobLauncher jobLauncher;
  @Autowired
  @Qualifier(value = "dataSource1")
  public DataSource mainDataSource;
  @Autowired
  @Qualifier(value = "dataSource2")
  public DataSource tempDataSource;
  @Autowired public StepBuilderFactory stepBuilderFactory;
  @Autowired public JobBuilderFactory jobBuilderFactory;
  @Autowired private RestTemplate myRestTemplate;
  @Qualifier(value = "createLocalSessionFactory")
  @Autowired
  private SessionFactory createLocalSessionFactory;
  @Qualifier(value = "createSessionFactory")
  @Autowired
  private SessionFactory createSessionFactory;
  @Bean
  RestTemplate restTemplate(RestTemplateBuilder builder) {
    RestTemplate restTemplate = new RestTemplate();
    List<HttpMessageConverter<?>> converters = restTemplate.getMessageConverters();
    for (HttpMessageConverter<?> converter : converters) {
      if (converter instanceof MappingJackson2HttpMessageConverter) {
        MappingJackson2HttpMessageConverter jsonConverter =
            (MappingJackson2HttpMessageConverter) converter;
        jsonConverter.setObjectMapper(new ObjectMapper());
        jsonConverter.setSupportedMediaTypes(
            ImmutableList.of(
                new MediaType(
                    "application", "json", MappingJackson2HttpMessageConverter.DEFAULT_CHARSET),
                new MediaType(
                    "text", "javascript", MappingJackson2HttpMessageConverter.DEFAULT_CHARSET)));
      }
    }
    return restTemplate;
  }
  @Bean
  public LocalSessionFactoryBean createLocalSessionFactory(
      @Qualifier("dataSource1") DataSource dataSource) {
    LocalSessionFactoryBean factory = new LocalSessionFactoryBean();
    factory.setDataSource(dataSource);
    factory.setPackagesToScan(
        new String[] {
          "X",
          "Y",
          "Z"
        });
    factory.setHibernateProperties(hibernateProperties());
    return factory;
  }
  @Bean
  public LocalSessionFactoryBean createSessionFactory(
      @Qualifier("dataSource2") DataSource dataSource) {
    LocalSessionFactoryBean factory = new LocalSessionFactoryBean();
    factory.setDataSource(dataSource);
    factory.setPackagesToScan(
        new String[] {
          "X",
          "Y",
          "Z"
        });
    factory.setHibernateProperties(hibernateProperties());
    return factory;
  }

我收到以下错误：

我省略了一些堆栈之间的跟踪，以保持重要的行在1.5.6.release版本中正常工作。我在这里看不到任何循环依赖关系。resttemplate函数也不依赖于mylogbatchconfiguration。我还试图改变顺序，将myrestemplatebean放在createsessionfactory bean之后，但仍然只有restemplate调用失败，而不是other。似乎other创建成功了。为什么要升级？任何帮助都将不胜感激。
