Using without Spring Boot

[prowave]

I have a project that I cannot convert to a Spring Boot project due to older dependencies. Can you provide a guide to use this project without Spring Boot? Is it possible?

Thank you for providing this.

Hi @prowave,

You just need to scan for the following springdoc class: org.springdoc.config.SpringDocConfiguration

For example, you can simply add on your application that ships the springdoc-openapi dependency: @ComponentScan(basePackages = {"org.springdoc"})

Hi,
Didn't work for me.
The webapp starts with no errors, but with nothing deployed.
In version 1.3.0 the path org.springdoc.config.SpringDocConfiguration is not available, shoud it be: "org.springdoc.core.SpringDocConfiguration" ? anyhow tried with both.

Thank's
Nuno

Hi @nmasilva,

Please have a look at the answer on stackoverflow:

• https://stackoverflow.com/questions/59871209/how-to-integrate-open-api-3-with-spring-project-not-spring-boot-using-springdo/59880655#59880655

• Mainly, you need to scan add spring-boot and spring-boot-autoconfigure dependencies.

• The classes are not by default visible. They are used by starters.

• You can load them from the follwing package: org.springdoc.core

• You can find the needed classes on the files: spring.factories

If you have a sample project to reproduce your issue, you can add the link for it on github and will have a look at it.

Hi @bnasslahsen

Thank you for your reply.
I already tried the solution on the link you posted.
Below is a project sandbox with the configuration that you posted above and is not working:
https://bitbucket.org/nmasilva/openapispringmvc

1. mvn clean package
2. docker-compose up
3. http://{docker_localhost_address}:8080/greeting/ (404 error)

If you removed the springboot and openapi dependencies in the war project pom, as de @import in the AppInitializer.java, it will work and you'll get as response 202 with the message: "Hello World!"

Thank you,
Nuno

@nmasilva,

You can find attached, a sample working configuration for spring apps (without spring-boot).

Hi @bnasslahsen

Thank you for the sample. Works like a charm :)
I've made some simplifications and push it into the sample project branch mentioned above.

Thank again,
Nuno

Great !
Will update the F.A.Q and stackoverflow as well.

We have Spring framework (version 5.3.22) based application, not a spring boot.

We have added springdoc-openapi (1.6.11) dependency along with below openapi configuration.

@Configuration 
@EnableWebMvc 
@ComponentScan(basePackages = {"org.springdoc","rest"}) 
@Import({org.springdoc.core.SpringDocConfiguration.class, 
         org.springdoc.webmvc.core.SpringDocWebMvcConfiguration.class, 
         org.springdoc.webmvc.ui.SwaggerConfig.class, 
         org.springdoc.core.SwaggerUiConfigProperties.class, 
         org.springdoc.core.SwaggerUiOAuthProperties.class, 
         org.springframework.boot.autoconfigure.jackson.JacksonAutoConfiguration.class}) 
public class OpenApiConfig implements WebMvcConfigurer { }

In our application, we have multiple projects having mixed of Java configurations and XML based configurations.

Both types of classes (java config like @controller/@service and XML definitions like <bean id="".... >) are having dependencies injected through @Autowred.

The classes having beans created through component scanning (@controller/@service) are working well, all the injected dependecies are resolved as expected.
But the classes having XML definitions are having issues, where dependencies injected through setter and bean ref are working fine, but the dependencies injected through @Autowired are found as null at runtime. Looks like @Autowired annotation itself is not getting resolved while creating bean of such classes. We have also verified that our XML context file has <context:annotation-config /> defined and so @Autowired should get resolved here.

Without this springdoc-openpi dependency and these OpenApiConfig, we are not facing this issue.

Does anyone have more insights here ?
