Mybatis-Plus 处理json字段

库里类型是json

 代码里注解即可

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.extension.handlers.JacksonTypeHandler;

@TableField(typeHandler = JacksonTypeHandler.class)
private List<String> sendPosition;

 类上注解

@TableName(value = "student", autoResultMap = true)
