访问在其他Bean方法中注入的Bean方法内的数据源

Question

在spring boot项目中，有没有办法在@Bean方法中使用注入对象。在我的示例中，isdatasourceUse()方法能够访问注入的数据源（来自dev或war配置文件）

@EnableScheduling
@Configuration
@EnableAspectJAutoProxy
@Profile({ "dev", "war" })
public class AppConfig {

   Logger logger = LoggerFactory.getLogger(AppConfig.class);

   @Autowired
   DBPropertyBean dbPropertyBean;

   @Bean(destroyMethod = "")
   @Profile("war")
   public DataSource jndiDataSource() throws IllegalArgumentException, NamingException {
      JndiObjectFactoryBean bean = new JndiObjectFactoryBean();
      bean.setJndiName(dbPropertyBean.getJndiName());
      bean.setProxyInterface(DataSource.class);
      bean.setLookupOnStartup(false);
      bean.afterPropertiesSet();
      return (DataSource) bean.getObject();
   }

   @Bean(destroyMethod = "close")
   @Profile("dev")
   public DataSource getDataSource() throws Exception {
      com.mchange.v2.c3p0.ComboPooledDataSource ds = new com.mchange.v2.c3p0.ComboPooledDataSource();
      ds.setUser(dbPropertyBean.getDsUsername());
      ds.setPassword(dbPropertyBean.getDsPassword());
      ds.setJdbcUrl(dbPropertyBean.getDsJdbcUrl());
      ds.setDriverClass(dbPropertyBean.getDsDriverClass());
      ds.setMaxPoolSize(dbPropertyBean.getDsMaxPoolSize());
      ds.setMinPoolSize(dbPropertyBean.getDsMinPoolSize());
      ds.setInitialPoolSize(dbPropertyBean.getDsInitPoolSize());
      ds.setAcquireIncrement(dbPropertyBean.getDsAcquireInc());
      ds.setAcquireRetryAttempts(dbPropertyBean.getDsAcquireRetryAtt());
      ds.setPreferredTestQuery(dbPropertyBean.getPreferredTestQuery());
      ds.setIdleConnectionTestPeriod(dbPropertyBean.getIdleConnectionTestPeriod());
      return ds;
   }
   @Bean
   public void datasourceUse() {
    //How to user datasource  here
   }

   }

使用如下：

@Autowired
public void datasourceUse(DataSource dataSource) {
    System.out.println(dataSource);
}
