报错原因：修改了已经执行过的迁移文件，比如V开头的叫V1.1__add_flyway_test_table.sql这个名字的文件，重新执行这个更改的迁移文件时就会产生新的校验和“checkSum"与原来校验和不符合，导致报该错误，原则上不可以直接修改已经执行的迁移文件，要修改需要新建迁移文件进行修改。
举例说明：比如最开始我有个文件V1.1add_flyway_test_table.sql，里面有个insert插入一条数据的sql，然后我启动整个项目，执行sql插入一条数据，且V开头的文件按常理已经执行过一次了，后面压根不会再次执行，但我手欠儿，再次对V开头的文件V1.1add_flyway_test_table.sql进行修改或者新增几条sql，然后再次启动项目就会报错误5的错误了。
解决方案：
1）方案1（不推荐）：涉及的2张表flyway_schema_history和flyway_test_table都删除，这会造成已有的数据丢失、混乱。2）方案2（推荐）：可以使用Flyway Maven 插件，双击运行：flyway:repair ，修复该错误，再重新执行：flyway:migrate。这样项目就能再次启动。3）方案3（不推荐）：删除2张表flyway_schema_history和flyway_test_table，然后重新启动项目把所有sql脚本从头到尾执行一遍。缺点：万一数据量太大太耗时，甚至可能出错。
碰到个问题：原来的V1.1add_flyway_test_table.sql里面有个内容，然后我对它修改后，执行flyway:repair，在执行flyway:migrate后，再次启动项目发现V1.1add_flyway_test_table.sql新增的内容没有执行？数据库没有产生新数据？
答案：应该是不会执行的，除非新增个V开头的迁移文件才会执行，即：对已经执行过的V开头的迁移文件修改后也不会执行，需要新建迁移文件进行修改才会生效。
