Cause: java.sql.SQLSyntaxErrorException: Unknown column 'data_json_map' in 'field list'问题分析与解决方案
问题原因
在 AgentDO 实体类中定义了 dataJsonMap 字段，它是一个临时字段用于存储解析后的 JSON 数据，不需要持久化到数据库。但在 SQL 查询中自动包含了这个字段，导致数据库报错 Unknown column 'data_json_map'。
解决方案
方法一：使用 @TableField(exist = false) 注解
在 AgentDO 类中，为 dataJsonMap 字段添加注解，明确表示它不是数据库字段：
@TableField(exist = false) // 表示这不是数据库字段
private Map<String, Object> dataJsonMap;OK
