I have a springboot application with swagger file. I use any swagger Maven plugin and it works.
My pom.xml file:
<dependency>
<groupId>io.swagger.core.v3</groupId>
<artifactId>swagger-core</artifactId>
<version>2.0.9</version>
</dependency>
<dependency>
<groupId>io.swagger.core.v3</groupId>
<artifactId>swagger-annotations</artifactId>
<version>2.0.9</version>
</dependency>
<dependency>
<groupId>io.swagger</groupId>
<artifactId>swagger-annotations</artifactId>
<version>1.5.23</version>
</dependency>
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.1.45</version>
</dependency>
I use an java enum
:
public enum TempReadingSource {
COLDROOM("coldroom"),
LOCAL("local"),
OVEN("oven");
private String value;
TempReadingSource(String value) {
this.value = value;
}
@Override
@JsonValue
public String toString() {
return String.valueOf(value);
}
@JsonCreator
public static TempReadingSource fromValue(String text) {
for (TempReadingSource b : TempReadingSource.values()) {
if (String.valueOf(b.value).equals(text)) {
return b;
}
}
return null;
}
}
and I have this error:
"Failed to convert value of type 'java.lang.String' to required type 'com.foo.TempReadingSource';
So I add a converter in my Springboot2 configuration:
@Configuration
public class StrubConfig extends WebMvcConfigurationSupport {
@Override
public FormattingConversionService mvcConversionService() {
FormattingConversionService f = super.mvcConversionService();
f.addConverter(new TempReadingSourceConverter());
return f;
}
}
and:
public class TempReadingSourceConverter implements Converter<String, TempReadingSource> {
@Override
public TempReadingSource convert(String source) {
try {
return TempReadingSource.fromValue(source);
} catch(Exception e) {
return null;
}
}
}
This Converter
solve my API (via postman) but now swagger-ui
is not found:
Solution is:
@Configuration
public class StrubConfig {
@Autowired
private FormattingConversionService conversionService;
@PostConstruct
public void registerCustomConverter() {
conversionService.addConverter(new TempReadingSourceConverter());
}
}
