Related to #3439. Yes I do create my own ObjectMapper.

ceefour · 2015-09-26T09:54:08Z

Tried to comment these:

//@EnableTransactionManagement
//@EnableWebMvc
//@EnableHypermediaSupport(type=HypermediaType.HAL)

and removed my own ObjectMapper, still error:

Caused by: org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [com.fasterxml.jackson.databind.ObjectMapper] is defined: expected single matching bean but found 3: objectMapper,halObjectMapper,_halObjectMapper

ceefour · 2015-09-26T10:09:53Z

Probably related to spring-projects/spring-hateoas#333

vpavic · 2015-09-26T10:11:13Z

Try simply annotating your own ObjectMapper instance with @Primary.

See this repo for an example of project demonstrating the issue that is similar to yours:
https://github.com/vpavic/activiti-rest-spring-hateoas-error
(BTW project uses Spring Boot 1.2.6.RELEASE but same happens with 1.3.0.M5)

ceefour · 2015-09-26T10:16:58Z

Tried to exclude HypermediaAutoConfiguration, didn't work: (which even if it works, is a bad idea anyway since I need this)

@SpringBootApplication(exclude=
        {HypermediaAutoConfiguration.class,
        LiquibaseAutoConfiguration.class} // java.lang.IllegalStateException: Cannot find changelog location: class path resource [db/changelog/db.changelog-master.yaml] (please add changelog or check your Liquibase configuration)
)

ceefour · 2015-09-26T10:28:20Z

@vpavic as I mentioned in #4029 (comment), I've removed my own jacksonMapper bean, still error, reducing the number of conflicts from 4 to 3 beans only. I don't know who creates the halObjectMapper and _halObjectMapper beans.

ceefour · 2015-09-26T10:31:48Z

Curiously this did not happen with boot 1.2.6. I simply wanted simple CORS support so instead of upgrading Spring to 4.2.1 I opted boot 1.3.0.M5 instead, now I've been struggling with Jackson a whole day :p If all else fails I probably will use boot 1.2.6 with spring 4.2.1 and hope that will work :)

ceefour · 2015-09-26T11:08:00Z

But yeah @vpavic thanks! That works! I'm still curious, why the workaround is actually adding my own @Primary bean.. instead of removing one. Weird.

Now I got 1.3.0.M5 + 4.2.1 running, but now struggling with CORS.. but that's another matter ;)
UPDATE: For those struggling with CORS + Spring Data REST, see http://stackoverflow.com/a/31748398/122441

ceefour · 2015-09-26T11:09:42Z

OK I know my original cause, it's because of this:

@Configuration @Profile("daemon")
public class MyRepositoryRestConfiguration extends
        RepositoryRestMvcConfiguration {

    @Override
    protected void configureRepositoryRestConfiguration(
            RepositoryRestConfiguration config) {
        super.configureRepositoryRestConfiguration(config);
        config.exposeIdsFor(Place.class);
    }

}

vpavic · 2015-09-26T11:30:05Z

@ceefour everything is explained in the description of project linked in my previous comment.

Generally there shouldn't issues having multiple ObjectMapper beans, as long as one of them is annotated with @Primary. Note that JacksonObjectMapperConfiguration contains such configuration.

However, when your project's configuration disables conditions defined by JacksonObjectMapperConfiguration that leaves your context with no @Primary instance of ObjectMapper causing NoUniqueBeanDefinitionException during startup.

ceefour · 2015-09-26T11:36:20Z

@vpavic Yes, but "my project's configuration" is not always "100% mine", in which case it's simply an extends RepositoryRestMvcConfiguration. So the actual code that "disables" is in Spring's code, my code merely "activates" that code, unknowingly what happens behind the scenes.

ceefour · 2015-09-26T16:32:53Z

Solution is:

Remove my own jacksonMapper
Refactor extends RepositoryRestMvcConfiguration with extends RepositoryRestConfigurerAdapter

Case solved.
