如何实现注解参数的值来源于其他注解相互传值？

[darkread]

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef="entityManagerFactoryDs1",
        transactionManagerRef="transactionManagerDs1",
        basePackages={"com.drrr.ds1.dao"})
public class DaoDs1Configuration {
    /**
     * 注入数据源
     */
    @Autowired
    @Qualifier("dataSourceDs1")
    private DataSource dataSource;

    /**
     * 配置 EntityManager 实体类
     * @param builder
     * @return
     */
    @Bean(name = "entityManagerDs1")
    public EntityManager entityManager(EntityManagerFactoryBuilder builder) {
        return entityManagerFactory(builder).getObject().createEntityManager();
    }

    /**
     * 配置 EntityManager 工厂实体
     * @param builder
     * @return
     */
    @Bean(name = "entityManagerFactoryDs1")
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder) {
        return builder
                .dataSource(dataSource)
                .packages("com.drrr.ds1.dao.entity") //设置实体类所在位置
                .persistenceUnit("persistenceUnitDs1")
                .build();
    }

    /**
     * 配置TransactionManager
     */
    @Bean(name = "transactionManagerDs1")
    public PlatformTransactionManager transactionManager(EntityManagerFactoryBuilder builder) {
        return new JpaTransactionManager(entityManagerFactory(builder).getObject());
    }
}

因为经常性需要些多数据源操作，在SpringBoot中需要写大量的DataSourceConfigure，如上所示完全可以写成基类，DataSource只需要继承即可，唯一修改的就是生成Bean的名称 通用为XXXXXX+数据源名
比如
entityManagerFactoryDs1
transactionManagerDs1
dataSourceDs1
等等
如果可以实现一个注解@DsNameSuffix，那么代码可以变成如下形式，当然我知道下面的形式是有语法错误的，但是就表达这样一个意思吧。

@DsNameSuffix
public class MyDsConfiguration extend DaoConfiguration{
}

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef="entityManagerFactoryDs1",
        transactionManagerRef="transactionManagerDs1",
        basePackages={"com.drrr.ds1.dao"})
public class DaoConfiguration{
    /**
     * 注入数据源
     */
    @Autowired
    @Qualifier("dataSource" + DsNameSuffix.value)
    private DataSource dataSource;

    /**
     * 配置 EntityManager 实体类
     * @param builder
     * @return
     */
    @Bean(name = "entityManager" + + DsNameSuffix.value)
    public EntityManager entityManager(EntityManagerFactoryBuilder builder) {
        return entityManagerFactory(builder).getObject().createEntityManager();
    }

    /**
     * 配置 EntityManager 工厂实体
     * @param builder
     * @return
     */
    @Bean(name = "entityManagerFactory"++ DsNameSuffix.value)
    public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder) {
        return builder
                .dataSource(dataSource)
                .packages("com.drrr.ds1.dao.entity") //设置实体类所在位置
                .persistenceUnit("persistenceUnitDs1")
                .build();
    }

    /**
     * 配置TransactionManager
     */
    @Bean(name = "transactionManager"++ DsNameSuffix.value)
    public PlatformTransactionManager transactionManager(EntityManagerFactoryBuilder builder) {
        return new JpaTransactionManager(entityManagerFactory(builder).getObject());
    }
}
