mysql - mysqldump 脚本上的 utf8 字符串无效

Question

我创建了数据库的副本，并将排序规则和字符集更改为 utf8mb4(最初是 latin1)，然后使用 mysqldump > 为 Flyway 数据库迁移创建脚本。

当我运行以下脚本时

-- MySQL dump 10.13  Distrib 5.5.62, for Win64 (AMD64)
--
-- Host: localhost    Database: feedback
-- ------------------------------------------------------
-- Server version   8.0.15

INSERT INTO `COMPONENT_GROUP` VALUES ('AAAB','AAA - MOTOR','LUBRIFICAÇÃO DO MOTOR','LUBRIFICAÇÃO DO MOTOR',NULL,NULL,20181219,1)

flyway 显示如下消息:

WARNING: DB: Invalid utf8 character string: 'C7C34F' (SQL State: HY000 - Error Code: 1300)
WARNING: DB: Incorrect string value: '\xC3O FUN...' for column 'claimed_name_pt' at row 10 (SQL State: HY000 - Error Code: 1366)

当我使用 SQLyog 和 MySQL Workbench 等工具运行转储脚本时，数据已正确插入，那么如何修复 Flyway 的问题？

Answer 1

找到缺失的部分来解决迁移问题。我必须将编码设置添加到 Flyway 的连接字符串中:

FLYWAY_URL="jdbc:mysql://${db_instance.default.address}:3306/${mysql_database.db-app.name}?characterEncoding=UTF-8&useUnicode=true"
