本文详细介绍了如何在Spring项目中配置和使用Flyway进行数据库迁移，包括在pom.xml中添加依赖，配置application-local.yml，创建迁移SQL文件，以及初始化flyway_schema_history和V1.1__init.sql文件。通过这些步骤，可以实现数据库版本管理和数据初始化。

1、在pom.xml文件夹下面配置相应的jar包

<dependency>
    <groupId>org.flywaydb</groupId>
    <artifactId>flyway-core</artifactId>
    <version>5.2.4</version>
</dependency>

2、在application-local.yml文件中配置flyway的相应的配置项

spring:  
  flyway:
    # 是否启用flyway
    enabled: true
    # 编码格式，默认UTF-8
    encoding: UTF-8
    # 迁移sql脚本文件存放路径，默认db/migration
    locations: classpath:db/migration
    # 迁移sql脚本文件名称的前缀，默认V
    sql-migration-prefix: V
    # 迁移sql脚本文件名称的分隔符，默认2个下划线__
    sql-migration-separator: __
    # 迁移sql脚本文件名称的后缀
    sql-migration-suffixes: .sql
    # 迁移时是否进行校验，默认true
    validate-on-migrate: true
    # 当迁移发现数据库非空且存在没有元数据的表时，自动执行基准迁移，新建schema_version表
    baseline-on-migrate: true

3、在resources文件创建sql 文件路径：db/migration

1、示例：V20210711.01__table_update.sql、V20210711.01__data_update.sql

4、初始化：flyway_schema_history.sql文件

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;

-- ----------------------------
-- Table structure for flyway_schema_history
-- ----------------------------
DROP TABLE IF EXISTS `flyway_schema_history`;
CREATE TABLE `flyway_schema_history` (
`installed_rank` int(11) NOT NULL,
`version` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
`description` varchar(200) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`type` varchar(20) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`script` varchar(1000) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`checksum` int(11) NULL DEFAULT NULL,
`installed_by` varchar(100) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
`installed_on` timestamp(0) NOT NULL DEFAULT CURRENT_TIMESTAMP,
`execution_time` int(11) NOT NULL,
`success` tinyint(1) NOT NULL,
PRIMARY KEY (`installed_rank`) USING BTREE,
INDEX `flyway_schema_history_s_idx`(`success`) USING BTREE
) ENGINE = InnoDB CHARACTER SET = utf8 COLLATE = utf8_general_ci ROW_FORMAT = Dynamic;

SET FOREIGN_KEY_CHECKS = 1;

5、初始化：V1.1__init.sql文件

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;


DROP TABLE IF EXISTS `flyway_test`;
CREATE TABLE `flyway_test`  (
  `flyway_test_id` int(11) NOT NULL AUTO_INCREMENT COMMENT '主键',
  `group_id` int(11) NULL DEFAULT NULL COMMENT '分组ID(关联外键)',
  `name` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL,
  `age` tinyint(3) NULL DEFAULT NULL,
  `remark` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '备注',
  `create_time` datetime NULL DEFAULT NULL COMMENT '创建时间',
  `create_user_id` int(11) NULL DEFAULT NULL COMMENT '创建者ID',
  `create_user` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '创建者姓名',
  `update_time` datetime NULL DEFAULT NULL COMMENT '更新时间',
  `update_user_id` int(11) NULL DEFAULT NULL COMMENT '更新者ID',
  `update_user` varchar(50) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '更新者姓名',
  `is_delete` tinyint(1) UNSIGNED ZEROFILL NOT NULL COMMENT '是否删除：注：0：否；1：是',
  PRIMARY KEY (`flyway_test_id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = 'flyway测试表' ROW_FORMAT = Dynamic;

SET FOREIGN_KEY_CHECKS = 1;
DROP TABLE IF EXISTS `flyway_test`;
