The bean 'metaDataSourceAdvisor', defined in null, could not be registered

Question

I\'ve updated the Spring Boot version from 2.0.3 to 2.1.1 but I\'m getting this:

***************************
APPLICATION FAILED TO START
********************         


        

Answer 1

Okay, I found the issue myself: I had @EnableGlobalMethodSecurity twice in my project:

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true) // <--
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
}

and

@SpringBootApplication
@EnableJpaRepositories(basePackages = {"mz.server.spring.repository"})
@EnableGlobalMethodSecurity(prePostEnabled = true, proxyTargetClass = true) // <--
@EntityScan(basePackages = "mz.server.hibernate.model")
@EnableTransactionManagement
@EnableScheduling
public class Application {
}

So that's a nice new Spring Boot feature I'd say.

Just watch out for unwanted duplicate annotations if you see this kind of error.
