如何将以下基于 xml 的 spring bean 转换为基于 Java 注释的 bean？

Question

 <bean id="string.message.service" class="com.ce.indiabringsService">
 <constructor-arg ref="com.ce.indiabrings.consumer" />
 <constructor-arg ref="com.ce.indiabrings.value.function" />
 </bean>

I want to convert this to java annotation based bean (@Bean).

Answer 1

1. create a method in configuration class
2. Construct mentioned object and return.
3. Annotate the method with @Bean

---

@Bean
public com.ce.indiabringsService getindiabringsServiceBean(){
    return new com.ce.indiabringsService(consumerObj,functionObj);
}

Answer 2

You need to create a class with org.springframework.context.annotation @Configuration annotation.

Then use @Bean annotation on a method and return appropriate bean object.

@Bean
public com.ce.indiabringsService getMessageService(){
    return new com.ce.indiabringsService(com.ce.indiabrings.consumer,com.ce.indiabrings.value.functioncom.ce.indiabrings.consumer);
}

Hope this helps you out.

Answer 3

One more option

   @Bean
public com.ce.indiabringsService getIndiabringsService(com.ce.indiabrings.consumer  
 consumerBean,com.ce.indiabrings.value.function functionBean){
 indiabringsService indiabringsServiceBean =new indiabringsService();
 indiabringsServiceBean.setConsumer(consumerBean);
 indiabringsServiceBean.setFunction(functionBean);
 return indiabringsServiceBean;
}

you can inject indiabringsService by using @Autowired .

for creating indiabringsService bean, Internally spring will automatically inject consumer and function beans while creating indiabringsService bean.

Answer 4

@Configuration
public class MyConfigurationClass {
    @Bean
    public com.ce.indiabringsService getIndiaBringsService() {
        return new com.ce.indiabringsService(com.ce.indiabrings.consumer,com.ce.indiabrings.value.functioncom.ce.indiabrings.consumer);
    }
}

And then you can autowire it as follows:

@Autowired
private com.ce.indiabringsService myIndiaBringsService;
