Spring boot 如何消除Spring Rest控制器中代码优先招摇的重复

我想先编写代码（而不是先设计），但我面临的代码并不枯燥。下面说明了我的意思，我希望Swigger UI适当显示两个端点：一个是必需的

amount

字段，另一个是可选的

amount

字段（这是一个简化的用例）

资源1：

@PostMapping(value = ["/createMoneyAmount"], produces = ["application/json"], consumes = ["application/json"])
fun createMoneyAmount(
        @RequestBody @Valid amount: MoneyAmount): Confirmation {
        return create(amount)
}

资源2：

@PostMapping(value = ["/createAltMoneyAmount"], produces = ["application/json"], consumes = ["application/json"])
fun createAltMoneyAmount(
        @RequestBody @Valid amount: AltMoneyAmount): Confirmation {
        return createAlt(amount)
}

其中它们之间的唯一区别是请求主体类型

但是，我想使用相同的类型，因为它们在定义上是相同的，除了通过单个Swagger属性注释为所需的单个属性：

required=true

使用

required=true

属性初始化：

@ApiModel(description = "An amount of money")
@JsonIgnoreProperties(ignoreUnknown = true)
data class MoneyAmount (

        @JsonSerialize(using = Padding::class)
        @ApiModelProperty(name = "amount", value = "The amount of money",
                required = true)
        var amount: BigDecimal? = null,
        @ApiModelProperty(value = "The currency")
        var currency: String? = null
)

@ApiModel(description = "An amount of money")
@JsonIgnoreProperties(ignoreUnknown = true)
data class AltMoneyAmount (

        @JsonSerialize(using = Padding::class)
        @ApiModelProperty(name = "amount", value = "The amount of money")
        var amount: BigDecimal? = null,
        @ApiModelProperty(value = "The currency")
        var currency: String? = null
)

Class不带

required=true

属性：

@ApiModel(description = "An amount of money")
@JsonIgnoreProperties(ignoreUnknown = true)
data class MoneyAmount (

        @JsonSerialize(using = Padding::class)
        @ApiModelProperty(name = "amount", value = "The amount of money",
                required = true)
        var amount: BigDecimal? = null,
        @ApiModelProperty(value = "The currency")
        var currency: String? = null
)

@ApiModel(description = "An amount of money")
@JsonIgnoreProperties(ignoreUnknown = true)
data class AltMoneyAmount (

        @JsonSerialize(using = Padding::class)
        @ApiModelProperty(name = "amount", value = "The amount of money")
        var amount: BigDecimal? = null,
        @ApiModelProperty(value = "The currency")
        var currency: String? = null
)

是否有任何方法（优雅或其他方式——最好是先编写代码）来避免创建两个基本相同的类，以便Swagger发出正确的文档——在本例中，指定

amount

字段在一个请求路径的主体中是“必需的”（通过红点），在另一个请求路径的主体中是可选的
