To get aspectj transactions working with java config.

@EnableWebMvc
@Configuration
@ComponentScan("com.yourdomain")
@EnableTransactionManagement(mode=AdviceMode.ASPECTJ)
public class ApplicationConfig extends WebMvcConfigurerAdapter {

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {

        //...
    }

    @Bean
    public JpaTransactionManager transactionManager() {

        JpaTransactionManager bean = new JpaTransactionManager(entityManagerFactory().getObject());
        return bean ;
    }

    @Bean
    public AnnotationTransactionAspect annotationTransactionAspect() {

        AnnotationTransactionAspect bean = AnnotationTransactionAspect.aspectOf();
        bean.setTransactionManager(transactionManager());
        return bean;
    }
}

If you are using maven:

    org.codehaus.mojo
    aspectj-maven-plugin
    1.7
    
        
            
                org.springframework
                spring-aspects
            
        
        1.8
        1.8
        1.8
        true
    
    
        
            
                compile
            
        
    

If you are using eclipse, this will ensure that the weaving is done when deploying inside eclipse:
