我´我要写一个库，做一些东西，使用spring数据。
这个想法是使用这个库的项目可以导入这个jar并使用这个库：mylib.dosomestuff（）。
以这种方式使用spring是可能的，我如何在dosomestuff（）方法中初始化applicationcontext，以便加载di和带有数据源的@configuration类？

public class MyLib {

@Autowired
private static SomeJpaRepository someJpaRepository;

  public static void doSomeStuff(){
    ...init ApplicationContext....
    ...setup DataSources...
    List<SomeEntity> someEntityList = someJpaRepository.someMethod();
  }

// or
  public static List<SomeEntity> getSomeEntityList() {
    return someJpaRepository.finAll();
  }
}

//other package
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "gxEntityManager", transactionManagerRef = "gxTransactionManager",
        basePackages = "com.gx")
public class GxConfig {

  @Primary
  @Bean(name = "gxDataSource")
  public DataSource gxDataSource() {
    DataSourceBuilder dataSourceBuilderGx = null;
    //..
    return dataSourceBuilderGx.build();
  }

  @Primary
  @Bean(name = "gxEntityManager")
  public LocalContainerEntityManagerFactoryBean gxEntityManagerFactory(EntityManagerFactoryBuilder builder) {
    return builder.dataSource(gxDataSource()).packages("com.gx").build();
 }

  @Primary
  @Bean(name = "gxTransactionManager")
  public PlatformTransactionManager gxTransactionManager(
        @Qualifier("gxEntityManager") EntityManagerFactory entityManagerFactory) {
    return new JpaTransactionManager(entityManagerFactory);
  }
}

//other package
public interface SomeEntity extends JpaRepository<SomeEntity, Long>
{
    SomeEntity findById(Long id);
}
