### Search before asking - [x] I had searched in the [issues](https://github.com/apache/seatunnel/issues?q=is%3Aissue+label%3A%22bug%22) and found no similar issues. ### What happened 生成json格式的本地文件时数字被转为科学计数法。 When generating a local file in JSON format, numbers are converted to scientific notation. 数据库中的字段fe_result,类型为decimal(10,2),source使用jdbc,sink使用LocalFile,格式指定为json,导出的json文件中的数字变更了科学技术法的表示方式。 When exporting data from a database, the field `fe_result` with a type of `DECIMAL(10,2)` is being converted to scientific notation in the exported JSON file. This issue occurs when using JDBC as the source and LocalFile as the sink, with the JSON format specified for the output. 数据表结构如下: The table DDL SQL: `CREATE TABLE `data_collection` ( `id` int(11) NOT NULL COMMENT '主键id', `code` varchar(50) NOT NULL COMMENT '编号', `fe_result` decimal(10,2) DEFAULT NULL COMMENT '记录值', PRIMARY KEY (`id`) USING BTREE ) ENGINE=InnoDB COMMENT='数据';` 数据库中的数据: data in DB-table: id:12312;code:1001015;fe_result:80.00 JSON结果文件: JSON file: {"id":12312,"code":"1001015","fe_result":8E+1} ### SeaTunnel Version 2.3.9 ### SeaTunnel Config ```conf env { job.mode = "BATCH" # 离线批处理模式 } source { Jdbc{ parallelism=1 plugin_output = "data_1" url = "jdbc:mysql://ip:p/data_db?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai" user = "" password = "" driver = "com.mysql.cj.jdbc.Driver" query = "select id, code, fe_result from data_collection" } } sink { LocalFile { plugin_input = "data_1" path = "../files/json" file_format_type = "json" } } ``` ### Running Command ```shell ./bin/seatunnel.sh --config config/mysql2file_json_for_2.3.9.config -m local ``` ### Error Exception ```log no exception. ``` ### Zeta or Flink or Spark Version Zeta by seatunnel-2.3.9 ### Java or Scala Version JDK 23. ### Screenshots _No response_ ### Are you willing to submit PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
