我有两个配置文件具有相同的bean定义和不同的@Qualifier，如下所示。并且想要在我的应用程序中使用那两个bean。为了避免在Spring启动时覆盖bean定义，我使用了ApplicationContextInitializer，并得到了以下异常。
@Bean(destroyMethod = "shutdown")
@Qualifier("batchAmazonSQSAsync")
public AmazonSQSAsync amazonSQS(@Qualifier("batchClientConfiguration") ClientConfiguration clientConfiguration,
@Qualifier("batchAWSCredentialsProviderChain") AWSCredentialsProviderChain credentialsProviderChain) {
AmazonSQSAsync amazonSQSAsyncClient = AmazonSQSAsyncClientBuilder.standard()
.withClientConfiguration(clientConfiguration).withCredentials(credentialsProviderChain)
.withRegion(Regions.fromName(region)).build();
return new AmazonSQSBufferedAsyncClient(amazonSQSAsyncClient);
}
@Bean
@Qualifier("batchClientConfiguration")
ClientConfiguration clientConfiguration() {
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost(proxyHost);
clientConfiguration.setProxyPort(proxyHostPort);
clientConfiguration.setProxyUsername(proxyUserName);
clientConfiguration.setProxyPassword(proxyPassword);
return clientConfiguration;
}
@Bean
@Qualifier("batchAWSCredentialsProviderChain")
AWSCredentialsProviderChain credentialsProviderChain() {
return new AWSCredentialsProviderChain(
new AWSStaticCredentialsProvider(new BasicAWSCredentials(accessKey, secretKey)));
}
@Bean(destroyMethod = "shutdown")
@Qualifier("priorityAmazonSQSAsync")
public AmazonSQSAsync amazonSQS(@Qualifier("priorityClientConfiguration") ClientConfiguration clientConfiguration,
@Qualifier("priorityAWSCredentialsProviderChain") AWSCredentialsProviderChain credentialsProviderChain) {
AmazonSQSAsync amazonSQSAsyncClient = AmazonSQSAsyncClientBuilder.standard()
.withClientConfiguration(clientConfiguration).withCredentials(credentialsProviderChain)
.withRegion(Regions.fromName(region)).build();
return new AmazonSQSBufferedAsyncClient(amazonSQSAsyncClient);
}
@Bean
@Qualifier("priorityClientConfiguration")
ClientConfiguration clientConfiguration() {
ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost(proxyHost);
clientConfiguration.setProxyPort(proxyHostPort);
clientConfiguration.setProxyUsername(proxyUserName);
clientConfiguration.setProxyPassword(proxyPassword);
return clientConfiguration;
}
@Bean
@Qualifier("priorityAWSCredentialsProviderChain")
AWSCredentialsProviderChain credentialsProviderChain() {
return new AWSCredentialsProviderChain(
new AWSStaticCredentialsProvider(new BasicAWSCredentials(accessKey, secretKey)));
}
public static void main(String[] args) {
ConfigurableApplicationContext ctx = new SpringApplicationBuilder(SqslistenerApplication.class)
.initializers(new ApplicationContextInitializer<GenericApplicationContext>() {
@Override
public void initialize(GenericApplicationContext applicationContext) {
applicationContext.setAllowBeanDefinitionOverriding(false);
}
}).run(args);
ctx.refresh();
