Spring-与现有的、不兼容的、名称和类相同的bean定义冲突

具体的例外情况是:

Failed to instantiate [org.springframework.context.annotation.AnnotationConfigApplicationContext]: Constructor threw exception;
nested exception is org.springframework.context.annotation.ConflictingBeanDefinitionException:
Annotation-specified bean name 'myService' for bean class [my.package.ejb.MyService] conflicts with existing, non-compatible bean definition of same name and class [my.package.other.ejb.MyService]

那些 MyService 接口甚至没有注释,它们代表EJB2.0无状态bean。

我的注释配置如下。

@Configuration
@ComponentScan("my.package")
@MapperScan("my.package")
public class ApplicationConfiguration {
    @Bean
    public DataSource dataSource() {
        return new JndiDataSourceLookup().getDataSource("...");
    }

    @Bean
    public SqlSessionFactoryBean sqlSessionFactory(final DataSource dataSource) {
        final SqlSessionFactoryBean sqlSessionFactory = new SqlSessionFactoryBean();
        sqlSessionFactory.setDataSource(dataSource);
        sqlSessionFactory.setConfigLocation(new ClassPathResource("..."));
        return sqlSessionFactory;
    }

    @Bean
    public DataSourceTransactionManager dataSourceTransactionManager(final DataSource dataSource) {
        return new DataSourceTransactionManager(dataSource);
    }
}

可能与 @MapperScan (来自MyBatis)和 @ComponentScan ?
