Java 如何为spring测试配置嵌套依赖关系？

我遇到的错误与在注入测试类之前解析属性有关。注入属性时，我以

${property.name}

结束。然而，考虑到存在嵌套依赖关系，测试类的配置似乎非常错误

特定错误：

由以下原因引起：java.net.URISyntaxException:索引8处的权限中的非法字符：https://${sqs.endpoint}

我有一个配置类来为

@Bean

加载特定的道具：

@Configuration
public class AWSConfig {

    private static final Logger LOGGER = LoggerFactory.getLogger(AWSConfig.class);
    private @Value("${sqs.endpoint}") String endpoint;

    @Bean(name = "awsClient")
    @Primary
    public AmazonSQSAsyncClient amazonSQSClient() {
        AmazonSQSAsyncClient awsSQSAsyncClient
                = new AmazonSQSAsyncClient();

        awsSQSAsyncClient.setEndpoint(endpoint);
        return awsSQSAsyncClient;
    }
}

这里是注入这个

@Bean

的地方：

@Component
public class SqsQueueSender {

    private static final Logger LOGGER = LoggerFactory.getLogger(SqsQueueSender.class);
    private final QueueMessagingTemplate queueMessagingTemplate;

    @Autowired
    @Qualifier("awsClient")
    AmazonSQSAsyncClient amazonSQSAsyncClient;

    public SqsQueueSender(AmazonSQSAsync amazonSQSAsyncClient) {
        this.queueMessagingTemplate = new QueueMessagingTemplate(amazonSQSAsyncClient);
    }

    //take advantage of convertAndSend to send POJOs in appropriate format
    public void send(String queueName, String message) {
        this.queueMessagingTemplate.convertAndSend(queueName, MessageBuilder.withPayload(message).build());
    }
}

这一切似乎都起作用了，至少应用程序启动并从任何一个位置打印日志。但是，我无法针对此代码运行单元测试。我不知道如何正确设置配置。下面是测试类的最新迭代：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
public class SqsQueueSenderTest {

    @Configuration
    static class ContextConfiguration {

        private @Value("${sqs.endpoint}") String endpoint;

        @Bean(name = "awsClient")
        @Primary
        public AmazonSQSAsyncClient amazonSQSClient() {
            AmazonSQSAsyncClient awsSQSAsyncClient
                    = new AmazonSQSAsyncClient();

            awsSQSAsyncClient.setEndpoint(endpoint);
            return awsSQSAsyncClient;
        }

        @Bean
        public SqsQueueSender sqsQueueSender() {
            SqsQueueSender sqsQueueSender = new SqsQueueSender(amazonSQSClient());

            // set up the client
            return sqsQueueSender;
        }
    }

    @Autowired
    SqsQueueSender sqsQueueSender;// = new SqsQueueSender(new AmazonSQSAsyncClient());


    private static final Logger LOGGER = LoggerFactory.getLogger(SqsQueueSenderTest.class);

    // attributes for in-memory sqs server
    AmazonSQSClient client;
    SQSRestServer server;
    SQSRestServerBuilder sqsRestServerBuilder;


    @Before
    public void startup() {
        LOGGER.info("Building in-memory SQS server");
        this.server = sqsRestServerBuilder.withPort(9324).withInterface("localhost").start();
        this.client = new AmazonSQSClient(new BasicAWSCredentials("x", "x"));
        client.setEndpoint("http://localhost:9324");
        client.createQueue("test");
        LOGGER.info("Finished building in-memory SQS server");
    }

    @After
    public void shutdown() {
        LOGGER.info("Stopping in-memory SQS server");
        server.stopAndWait();
        LOGGER.info("Finished stopping in-memory SQS server");
    }

    @Test
    public void testSending() {
        LOGGER.info("~~~~~~~~~~~~~");
        sqsQueueSender.send("test", "new message");
        LOGGER.info("The current queues are" + client.listQueues().toString());
        LOGGER.info("~~~~~~~~~~~~~");
    }
}

Joe，首先将您的连接属性放入资源中进行测试：

src/test/resouces/test.properties

然后将其添加到测试类定义中：

@PropertySource(
          value={"classpath:test.properties"},
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
public class SqsQueueSenderTest {

最后，在您的配置类中添加以下bean：

@Configuration static class ContextConfiguration {

     @Bean
     public static PropertySourcesPlaceholderConfigurer properties() throws Exception {
            return new PropertySourcesPlaceholderConfigurer();
     }
}

不要忘记在属性文件中放置“sqs.endpoint”url

在我看来，这是将属性注入测试类的更干净的方法之一。

谢谢，但我实际上将

PropertySource

放在内部

@Configuration

类上，并且实际上必须在

test/resources

目录中创建一个新的props文件。这就是我关于测试文件的意思：）。是的，您也可以将注释放在bean本身上。不管怎样，我很高兴它对你有用
