问题描述
为了提高我的服务的可配置性，我实现了一种逻辑，以获取要在运行时注册的，在我的配置中定义的bean，例如：
READ_BIT在应用程序启动时，引导程序组件读取配置并根据其在配置中的定义实例化Bean：
receivers:
myResource:
sourceExchange: MyExchange
entity: "com.company.domain.MyEntity"
writer: "com.company.writer.MyEntityDBWriter"
这很好用，并允许可配置的Bean注册，而不会丢失自动配置/自动装配支持。
由于这些bean中采用的逻辑是DB-Writing-Logic，因此我想通过使用 @Component
@Slf4j
public class ReceiverBootstrapper {
private ReceiversConfigurationModel configuration;
private ConfigurableApplicationContext context;
private Environment environment;
public ReceiverBootstrapper(ReceiversConfigurationModel receiversConfigurationModel,ConfigurableApplicationContext context,Environment environment) {
this.configuration = receiversConfigurationModel;
this.context = context;
this.environment = environment;
}
@postconstruct
public void bootstrapReceivers() throws ClassNotFoundException,illegalaccessexception,InstantiationException {
Map<String,ReceiverConfigurationModel> receiverMap = this.configuration.getReceivers();
for (String receiverName : receiverMap.keySet()) {
ReceiverConfigurationModel receiverConfigurationModel = this.configuration.getReceivers().get(receiverName);
Class writerClass = Class.forName(receiverConfigurationModel.getWriter());
AbstractDocumentWriter writer = (AbstractDocumentWriter) writerClass.newInstance();
context.getbeanfactory().registerSingleton(receiverName + "Writer",writer);
context.getbeanfactory().autowireBean(writer);
writer.postconstruct();
...
}
}
进行自动事务管理来扩展此概念，但是我想我将不得不告诉某些Manager遵守实例化和注册的手册上的这些注释。豆。
