我正在使用swagger“2.0”创建我的项目 . 问题是我想在请求体中有一些必填字段，需要进行验证 . Swagger无法验证正文中的字段（Schema Object），我需要在到达实际的API实现之前抛出400 Bad请求 .
Here's the actual code I wrote in my yaml file.
'/groupChats/{pathparam}/message':
post:
tags:
- group chats
description: Adds a message to the given group chat.
operationId: addMessageToGroupChat
consumes:
- application/json
parameters:
- name: pathparam
description: some pathparam
in: path
required: true
type: string
- name: addMessageInput
description: The content of the message to add to the groupChat.
in: body
required: true
schema:
$ref: '#/definitions/AddMessageInput'
- name: Authorization
in: header
type: string
required: false
description: >-
The identification token. It can be a JSON web token, a Basic
Authorization token, etc.
- name: mode
in: header
type: string
required: false
description: >-
there is a high performance mode that tries and optimize the messages
responses:
'201':
description: Message added.
schema:
$ref: '#/definitions/AddMessageOutput'
AddMessageInput:
type: object
properties:
body:
description: The message body.
type: string
**required: true**
tags:
description: some desc
type: array
items:
$ref: '#/definitions/MessageTag'
**required:
- body**

@jsonignore
public void setIsNew(boolean isNew) {
this.isNew = isNew;

@override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (o == null || getClass() != o.getClass()) {
return false;
}
AddMessageInput addMessageInput = (AddMessageInput) o;
return Objects.equals(body, addMessageInput.body) &&
Objects.equals(tags, addMessageInput.tags);

@override
public String toString() {
StringBuilder sb = new StringBuilder();
sb.append("class AddMessageInput {\n");
sb.append(" body: ").append(toIndentedString(body)).append("\n");
sb.append(" tags: ").append(toIndentedString(tags)).append("\n");
sb.append("}");
return sb.toString();
}
/**
Convert the given object to string with each line indented by 4 spaces
(except the first line).
*/
private String toIndentedString(Object o) {
if (o == null) {
return "null";
}
return o.toString().replace("\n", "\n ");
}
}
我通过设置 required as true 并通过在 required: 下添加属性"body"来尝试两种方式（以粗体显示），但它显示错误's not working. Only in swagger UI it' . 但是当我尝试直接从外部命中API（比如Postman）时，它允许我按照AddMessageInput模型中的预期在没有body（String）的情况下点击API . 我不得不明确地检查这个字段 . 如果我遗漏任何东西，请建议我 .
TIA对您的回复 .
