Springdoc-openapi-ui OpenAPI Java生成器继承

Question

**代码：（类名已重命名）**

两个版本中的CheeseDTO YAML：

   CheeseDTO:
     type: object
     properties:
       cheeseType:
         type: string
     discriminator:
       propertyName: cheeseType    

使用springdoc-openapi-ui 1.3.9，我的yaml是这样生成的：

   MyDTO:
       type: object
       properties:
           cheeses:
           type: array
           items:
               $ref: '#/components/schemas/CheeseDTO'

MyDTO:
       type: object
       properties:
           cheeses:
           type: array
           items:
               oneOf:
               - $ref: '#/components/schemas/SoftCheeseDTO'
               - $ref: '#/components/schemas/HardCheeseDTO'    

昂首阔步3注释：

@Schema(
name = "CheeseDTO",
discriminatorProperty = "cheeseType",
discriminatorMapping = {@DiscriminatorMapping(value = "Brie", schema = SoftCheeseDTO.class),
 @DiscriminatorMapping(value = "Banon", schema = SoftCheeseDTO.class),
 @DiscriminatorMapping(value = "Cheddar", schema = HardCheeseDTO.class)})
abstract CheeseDTO

   private String cheeseType;

@Schema(allOf = {CheeseDTO.class})
SoftCheeseDTO extends CheeseDTO

@Schema(allOf = {CheeseDTO.class})
HardCheeseDTO extends CheeseDTO

OpenAPi生成器maven插件

               <performBeanValidation>false</performBeanValidation>
               <serializationLibrary>jackson</serializationLibrary>
             </configOptions>
           </configuration>
         </execution>
       </executions>
     </plugin>

有没有办法用springdoc-openapi-ui>1.4.0生成列表 ？我必须更改我的大摇大摆的注释或更改我的java生成器吗？

我们在较新的sprindoc openapi UI中也看到了同样的问题。您需要坚持使用springdoc-openapi-ui 1.3.9。

Generator上也有类似的问题：

在openapi-generator-maven-plugin 4.3.1之前，您可以通过以下方式完成：

CheeseDTO:
  type: object
  properties:
    cheeseType:
      type: string
  discriminator:
    propertyName: cheeseType
    mapping:
      SOFT_CHEESE: '#/components/schemas/SoftCheeseDTO'
      HARD_CHEESE: '#/components/schemas/HardCheeseDTO'

MyDTO:
  type: object
  properties:
    cheeses:
      type: array
        items:
          $ref: '#/components/schemas/CheeseDTO'
