以代码的形式实现flyway的迁移

如果某个项目被另一个项目以jar包的形式依赖，此项目的flyway实现如下

package com.enmo.dbaas.firewall.common.config;

import org.flywaydb.core.Flyway;
import org.flywaydb.core.api.configuration.FluentConfiguration;
import org.springframework.stereotype.Component;
import com.enmo.dbaas.firewall.common.utils.SpringContextProvider;
import lombok.extern.slf4j.Slf4j;

/**
 * @ClassName: FlywayConfig.java
 * @Description:
 * @Author guo.yu
 * @Version V1.0.0
 * @Date 2019-05-12 19:46:10
 */
@Component
@Slf4j
public class FlywayConfig {

    private static final String FLYWAY_TAB_NAME = "dbaas_firewall_flyway_schema_history";
    
    private static final String FLYWAY_LOCATION = "db/firewall/migration";

    public FlywayConfig(SpringContextProvider provider) {
        Flyway defFlyway = null;
        try {
            defFlyway = provider.getBean(Flyway.class);
        } catch (Exception e) {
            log.warn("flyway is not enabled.");
        }
        if (defFlyway != null) {
            firewallMigrate(defFlyway);
        }

    }

    @SuppressWarnings("deprecation")
    public void firewallMigrate(Flyway defFlyway) {
        FluentConfiguration config = new FluentConfiguration();

        config.dataSource(defFlyway.getDataSource())
               .baselineOnMigrate(defFlyway.isBaselineOnMigrate())
               .locations(FLYWAY_LOCATION)
               .table(FLYWAY_TAB_NAME)
               //允许运行之前版本（相对于schema表最新版本）的schema文件
               .outOfOrder(true)
               .load()
               .migrate();
        
        
    }

}
