天坑 flayway 6.4.4 升级到9.0.7 java.lang.NoSuchMethodError: FluentConfiguration ignoreMissingMigrations

        先看错误信息：

        在作者升级flayway的时候出现了如题的问题，问题的原因就是spring boot 版本和flayway 不兼容。那么如何解决呢？ 下面二步简单解决。

1. 在application 中把如图的FlywayAutoConfiguration.class 自动配置取消掉。

2. 手动注入FlaywayConfiguration FluentConfiguration 像如下， 不要全抄

 @Bean
    @ConditionalOnProperty(prefix = "spring.flyway", name = "enabled", matchIfMissing = true)
    public Flyway flyway(DataSource dataSource, RedisDistributedLock redisDistributedLock) {
        String lockKey = "Flyway-" + appName;
        boolean locked = redisDistributedLock.lock(lockKey, 60_000L);
        if (!locked) {
            log.error("Flyway获取lockKey=[{}]的redis锁超时", lockKey);
            // 停掉应用,静待下一次的重启
            Runtime.getRuntime().halt(1);
        }
        try {
            log.info("::::::::::::::flyway begin");
            Flyway flyway = Flyway.configure().dataSource(dataSource).load();
            flyway.migrate();
            log.info("::::::::::::::flyway end");
            return flyway;
        } finally {
            redisDistributedLock.unLock(lockKey);
        }
    }

 真实有效哦，试试！！！
