how to hook the array field in postgreSql with mybatis-plus?

Question

I tried to hook the field "path" in my custom class "category" with a List or Array class to a column in my postgreSql with a data type of int4[], but I failed. The code is as follows (note, using the kotlin language and springboot framework) (By the way, I tried building a bean in java, but springboot couldn't scan the java bean)

data class Category(
    val id: Int,
    val name: String,
    val path :IntArray
) {
}

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.argentrise.antinomy.interaction.dao.mapper.CategoryMapper">
    <resultMap id="BaseResultMap" type="com.argentrise.antinomy.interaction.entity.Category">
        <id column="id" property="id" />
        <result column="name" property="name" />
        <result column="path" property="path" />
    </resultMap>
</mapper>

@Mapper
interface CategoryMapper : BaseMapper<Category> {
}

interface IPlayerService {
    fun getPlayer() : Player
    fun getCategory() : Category
}

@Service
class PlayerService : IPlayerService{

    @Autowired
    lateinit var categoryMapper : CategoryMapper

    override fun getCategory(): Category {
        val query : QueryWrapper<Category> = QueryWrapper()
        return categoryMapper.selectList(query)[0]
    }
}

@RestController
@RequestMapping("/player")
class PlayerController {
    @Autowired
    lateinit var playerService : PlayerService

    @GetMapping("/test")
    fun test() : Category{
        println("@-@")
        return playerService.getCategory()
    }


}
