Question

我使用flyway + hibernate验证。我有飞路豆：

@Component
public class DbMigration {

    private static final Logger LOG = LoggerFactory.getLogger(DbMigration.class);

    private final Config config;

    @Autowired
    public DbMigration(Config config) {
        this.config = config;
    }

    public void runMigration() {
        try {
            Flyway flyway = new Flyway();
            flyway.configure(properties());
            int migrationApplied = flyway.migrate();
            LOG.info("[" + migrationApplied + "] migrations are applied");
        } catch (FlywayException ex) {
            throw new DatabaseException("Exception during database migrations: ", ex);
        }
    }

    public Properties properties() {
        //my prop
    }
}

在Apllication类中，我这样做：

public static void main(String[] args) {
        try {
            AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(ApplicationConfiguration.class);
            context.getBean(DbMigration.class).runMigration();

但我的hibernate在runMigration();之前启动并验证throw exeption。我怎么才能开始呢？

运行迁移
启动hibernate验证

编辑：

  @Bean
    @Autowired
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource datasource) {
        log.info("entityManagerFactory start");
        dbMigration.runMigration();

但我认为这很糟糕

在Spring应用程序配置中，如果您有实体管理器工厂bean配置，则可以使其依赖于flyway bean，以便在它之后进行初始化。类似的东西：

@Bean
@DependsOn("flyway")
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
    // Initialize EntityManagerFactory here
}

flyway bean配置可以是：

@Bean(initMethod = "migrate")
public Flyway flyway() {
    Flyway flyway = new Flyway();
    // configure bean here
    return flyway;
}

如何在休眠验证之前启动flyway迁移？
