Spring boot 2.1.3 update from 2.0.6 causes an BeanDefinitionParsingException for util:map

Question

I have below map bean definition in application context xml and used the map in controller which is causing BeanDefinitionParsingException for spring boot 2.1.3 upgrade. It works fine in 2.0.6 version.

Does anyone know how to resolve this issue?

Defining "spring.main.allow-bean-definition-overriding=true" in application properties doesn't fix the issue.

@SpringBootApplication
@PropertySource("classpath:app.properties")
public class Application extends SpringBootServletInitializer {


    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) throws Exception {// NOSONAR
        SpringApplication.run(Application.class, args);
    }

}

@Configuration
public class ApplicationConfig {

    @Configuration
    @ImportResource("classpath*:applicationContext.xml")    
    public static class XmlImportingConfiguration {
    }

}

@Controller
@RequestMapping("/")
public class MyController{
    @Resource(name="lookup")
    private Map<String,String> lookup;

}

Error:

Answer 1

I have workaround for this problem. Basically moved the map from applicationContext.xml to application properties and retrieved using @Value like below.

app.properties
lookup={'60':'Last 1 hour','480':'Last 8 hours','1440':'Last 24 hours','2880':'Last 2 days'}

ApplicationProperties.java
    @Value("#{${lookup}}")
    private Map<String,String> lookupTimeinterval;
