[英]Use LinkedHashMap instead of HashMap for Swagger dictionary type (Java codegen)?
我正在使用 openapi 3.0.2 和 codegen 插件:
<groupId>io.swagger.codegen.v3</groupId>
<artifactId>swagger-codegen-maven-plugin</artifactId>
<version>3.0.14</version>
我正在使用此处描述的 swagger 字典/hashmap 类型:
https://swagger.io/docs/specification/data-models/dictionaries/
openapi: "3.0.2"
...
Labels:
type: object
additionalProperties:
type: string
minLength: 1
description: A description.
当我为此生成 Java 代码时,它被建模为一个扩展HashMap
的类:
@ApiModel(description = "A description.")
@Validated
@javax.annotation.Generated(value = "io.swagger.codegen.v3.generators.java.SpringCodegen", date = "2020-02-26T12:17:36.248Z[Europe/London]")
public class Labels extends HashMap<String, String> {
...
}
有什么方法可以指示 swagger 使用LinkedHashMap
而不是HashMap
吗? (无需从代码生成中排除此类并手动修改它)。
我想在返回给客户时控制这本词典中条目的顺序。
我使用了一个maven插件来修改生成的文件:
<plugin>
<groupId>org.codehaus.gmavenplus</groupId>
<artifactId>gmavenplus-plugin</artifactId>
<executions>
<execution>
<id>modify-swagger</id>
<phase>generate-sources</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<properties>
<property>
<name>targetDir</name>
<value>${project.build.directory}</value>
</property>
</properties>
<scripts>
<script><![CDATA[
def labelsFile = new File(targetDir
+ "/swagger-codegen/src/main/java/com/acme/models/Labels.java")
def labelsFileContents = labelsFile.text
if (labelsFileContents == null) {
throw Exception();
}
def newLabelsFileContents = labelsFileContents.replaceAll('HashMap', 'LinkedHashMap')
labelsFile.write(newLabelsFileContents)
]]></script>
</scripts>
</configuration>
</execution>
</executions>
</plugin>
您可以使用instantiationTypes
选项:
<plugin>
<groupId>io.swagger</groupId>
<artifactId>swagger-codegen-maven-plugin</artifactId>
<version>2.4.9</version>
<configuration>
<language>java</language>
</configuration>
<executions>
<execution>
<id>generate-java</id>
<goals>
<goal>generate</goal>
</goals>
<configuration>
<language>spring</language>
<instantiationTypes>map=java.util.LinkedHashMap</instantiationTypes>
</configuration>
</execution>
</executions>
</plugin>
