i have this configuration class:
@Configuration
public class ApplicationConfig {
@Bean
public ObjectMapper obMapper() {
return new ObjectMapper();
}
}
And this in my service:
@Qualifier("obMapper")
private ObjectMapper obMapper;
But i recieve this error:
Parameter 0 of method jacksonCodecCustomizer in org.springframework.boot.autoconfigure.http.codec.CodecsAutoConfiguration$JacksonCodecConfiguration required a single bean
How should i create it?
If you want to inject the bean you have to use one of these:
1. Autowire the dependency
@Autowired
@Qualifier("obMapper")
private ObjectMapper objectMapper;
2. Use setter injection
private ObjectMapper objectMapper;
@Autowired
public setObjectMapper(ObjectMapper objectMapper) {
this.objectMapper = objectMapper;
}
You can find more details for example in this article on Baeldung.
