这是我的binlog文件, 我刚刚执行的delete语句误删除了部分数据，我想恢复我删除的数据。涉及的数据库是db_iam 数据表是 t_iam_func_auth

进入binlog目录

‌

确认最新binlog文件‌

根据文件列表，最新的是mysqld-bin.054745（数字最大的文件）6。

解析binlog内容‌

使用mysqlbinlog工具解析，注意添加--database和--base64-output参数：

shell 复制代码 
mysqlbinlog --base64-output=decode-rows -v --database=db_iam mysqld-bin.054745 > parsed_binlog.sql

定位DELETE语句‌

在生成的parsed_binlog.sql中搜索以下内容：

表名t_iam_func_auth

操作类型### DELETE FROM，这是其中部分数据：

    public static List<String> convertDeleteToInsert(String filePath) throws IOException {
        List<String> result = new ArrayList<>();
        StringBuilder fileContent = new StringBuilder();

        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                fileContent.append(line).append("\n");
            }
        }

        Matcher deleteMatcher = DELETE_PATTERN.matcher(fileContent.toString());
        while (deleteMatcher.find()) {

            while (fieldMatcher.find()) {
                String fieldNum = fieldMatcher.group(1);
                String value = fieldMatcher.group(2);

                if ("NULL".equals(value)) {
                    values.add("NULL");
                } else if ("9".equals(fieldNum) || "11".equals(fieldNum)) {
                    // 处理时间戳字段
                    try {
                        long timestamp = Long.parseLong(value);
                        String formattedDate = DATE_FORMAT.format(new Date(timestamp * 1000L));
                        values.add("'" + formattedDate + "'");
                    } catch (NumberFormatException e) {
                        values.add("'" + value.replace("'", "''") + "'");
                    }
                } else {
                    values.add("'" + value.replace("'", "''") + "'");
                }
            }

            if (!values.isEmpty()) {
                String insert = String.format(
                        "INSERT INTO `%s`.`%s` VALUES (%s)",
                        database, table, String.join(", ", values)
                );
                result.add(insert);
            }
        }

        return result;
    }
}

这里注意时间搓转为年月日格式。else if ("9".equals(fieldNum) || "11".equals(fieldNum))这段代码需要修改。

最后生成类似的代码:
