charset=UTF-8 Content-Transfer-Encoding: 8bit ## 问题描述 用户反馈：菜单comment字段可能出现乱码 ## 问题分析 ### 乱码原因 1. **MySQL连接字符集不匹配**： - 客户端未指定字符集 - 默认字符集与数据不匹配 2. **终端显示问题**： - 终端编码与数据库编码不一致 - 查询结果传输过程中字符集转换错误 ### 数据库状态检查 ```sql -- 当前配置 character_set_client = utf8mb4 ✅ character_set_connection = utf8mb4 ✅ character_set_database = utf8mb4 ✅ character_set_results = utf8mb4 ✅ -- 表字符集 sys_menu: utf8mb4_general_ci ✅ ``` ## 解决方案 ### 1. 更新import_menu.sh导入脚本 **修改**：所有mysql命令添加`--default-character-set=utf8mb4` ```bash # 修复前 ❌ mysql -h"$DB_HOST" -u"$DB_USER" -p"$DB_PASS" "$DB_NAME" < "$SQL_FILE" # 修复后 ✅ mysql -h"$DB_HOST" -u"$DB_USER" -p"$DB_PASS" --default-character-set=utf8mb4 "$DB_NAME" < "$SQL_FILE" ``` ### 2. 创建字符集修复工具 **新增**：`sql/fix_charset.sh` **功能特性**： - ✅ 检查数据库字符集配置 - ✅ 检查表字符集设置 - ✅ 测试查询菜单数据 - ✅ 一键修复表字符集 - ✅ 自动备份原表数据 **使用方法**： ```bash cd sql ./fix_charset.sh ``` **修复流程**： 1. 检查当前字符集配置 2. 显示菜单数据（检测乱码） 3. 用户确认是否修复 4. 创建备份表 5. 转换表字符集为utf8mb4 6. 验证修复结果 ## 预防措施 ### 数据导入时 ```bash # 始终指定字符集 mysql --default-character-set=utf8mb4 -h... < file.sql ``` ### 数据查询时 ```bash # 查询时指定字符集 mysql --default-character-set=utf8mb4 -h... -e "SELECT ..." ``` ### 应用程序配置 ```yaml # application.yml中确保 spring: datasource: url: jdbc:mysql://...?characterEncoding=utf8mb4&useUnicode=true ``` ## 验证结果 ```sql SELECT menu_id, menu_name, remark FROM sys_menu WHERE parent_id = 0; 2000 盘古管理 盘古用户平台业务菜单 ✅ 1 系统管理 系统管理目录 ✅ 2 系统监控 系统监控目录 ✅ ``` ## 相关文件 - sql/import_menu.sh - 菜单导入脚本（已修复） - sql/fix_charset.sh - 字符集修复工具（新增） --- 作者：湖北新华业务中台研发团队 --- sql/fix_charset.sh | 97 ++++++++++++++++++++++++++++++++++++++++++++++ sql/import_menu.sh | 6 +-- 2 files changed, 100 insertions(+), 3 deletions(-) create mode 100755 sql/fix_charset.sh diff --git a/sql/fix_charset.sh b/sql/fix_charset.sh new file mode 100755 index 0000000..37ab325 --- /dev/null +++ b/sql/fix_charset.sh @@ -0,0 +1,97 @@ +#!/bin/bash +# ============================================================ +# 脚本名称：fix_charset.sh +# 功能说明：修复数据库字符集和乱码问题 +# 作 者：湖北新华业务中台研发团队 +# 创建时间：2026-01-31 +# 使用方法：./fix_charset.sh +# ============================================================ + +set -e + +# 数据库配置 +DB_HOST="8.148.25.55" +DB_PORT="3306" +DB_USER="root" +DB_PASS="aly2024A" +DB_NAME="pguser-db" + +echo "============================================================" +echo "数据库字符集检查与修复工具" +echo "============================================================" +echo "" + +# 1. 检查数据库字符集 +echo "1. 检查数据库字符集配置..." +mysql -h"$DB_HOST" -P"$DB_PORT" -u"$DB_USER" -p"$DB_PASS" --default-character-set=utf8mb4 -e " +SHOW VARIABLES LIKE 'character_set%';
