springboot 集成 liquibase 管理数据库版本

项目有时候去要项目启动就生成数据库表 或多人开发维护版的时候 用这个比较方便管理
自己去找liquibase gva坐标

package com.tlsq.service.flowable.config;

import liquibase.Liquibase;
import liquibase.database.Database;
import liquibase.database.DatabaseConnection;
import liquibase.database.DatabaseFactory;
import liquibase.database.jvm.JdbcConnection;
import liquibase.exception.DatabaseException;
import liquibase.resource.ClassLoaderResourceAccessor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.sql.DataSource;

/**

 */
@Configuration
public class DatabaseConfiguration {

    // 表的开头命名
    private static final String LIQUIBASE_CHANGELOG_PREFIX = "T_";

    @Bean
    public Liquibase liquibase(DataSource dataSource) {
        Liquibase liquibase = null;
        try {
            DatabaseConnection connection = new JdbcConnection(dataSource.getConnection());
            Database database = DatabaseFactory.getInstance().findCorrectDatabaseImplementation(connection);
            database.setDatabaseChangeLogTableName(LIQUIBASE_CHANGELOG_PREFIX + database.getDatabaseChangeLogTableName());
            database.setDatabaseChangeLogLockTableName(LIQUIBASE_CHANGELOG_PREFIX + database.getDatabaseChangeLogLockTableName());
            //  自己sql表脚本路径
            liquibase = new Liquibase("custom/flowable-extend.sql", new ClassLoaderResourceAccessor(), database);
            liquibase.update("luyang");
            return liquibase;
        } catch (Exception e) {
            throw new RuntimeException("Error creating liquibase database", e);

        } finally {
            closeDatabase(liquibase);
        }
    }

    private void closeDatabase(Liquibase liquibase) {
        if (liquibase != null) {
            Database database = liquibase.getDatabase();
            if (database != null) {
                try {
                    database.close();
                } catch (DatabaseException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}

springboot 2.0以后在application.yml文件加上
spring:
    liquibase:
        enabled: false

--liquibase formatted sql
--changeset luyang:1

-- 用户操作类型表 所用sql格式看着比xml舒服 给出格式自己去修改 一定要加上文件头两个申明注意不要有空格

drop table if exists `t_operation_type`;

insert into t_operation_type (type_) values ('通过');

-- 不允许用户id_NAME映射表 用户ID重复
alter table flowable.t_user_id_name add unique (user_id_);
