Hibernate &引用；未指定必需参数"；在发布带有日期的json时

上下文：我将Kotlin与Micronaut一起使用，对于这个项目，我不会添加Spring依赖项

我成功地创建了一个Hello Word enpoint，我可以从邮递员那里发布到它。当我将数据演化为生日（java.time.LocalDate）时，问题就开始了

抄袭自邮递员

curl --location --request POST 'localhost:8080/accountholders' --header 'Content-Type: application/json' --data-raw '{
    "name": "Jimis",
    "age":42,
    "birthDate":"1978-04-14",
    "category":"'\''Student'\''"
}'

导致

{
    "message": "Required argument [AccountHolder accountHolder] not specified",
    "path": "/accountHolder",
    "_links": {
        "self": {
            "href": "/accountholders",
            "templated": false
        }
    }

整个项目（分支日期问题中的错误，而不是主项目中的错误）

您应该用

@Body

注释方法参数：

import io.micronaut.http.annotation.*

// ...


@Post
@Consumes(MediaType.APPLICATION_JSON)
fun addAccountHolder(@Body accountHolder: AccountHolder): AccountHolder {
    return accountHolderService.addAccountHolder(accountHolder)
}

太容易了，我找了整整一个下午。谢谢你问了我的问题，但pelase，如果你不介意的话，最后一句话是：什么是日期和日期时间的好方法？io.micronaut.core.convert.format.format是否值得注明日期？我对生日的上述方法很在行吗？

“io.micronaut.core.convert.format.format是否值得使用日期？”

-

@format

可用于

日期。有一个例子就是这样的。这对你的处境是否是最好的，取决于你是否知道你在努力做什么。
