Question

我正在尝试在测试中从application.yml加载InfluxDB属性。

@RunWith(SpringRunner.class)
@EnableConfigurationProperties(InfluxDBProperties.class)
public class StupidRepoIntegrationTest {
    @Autowired
    public InfluxDBProperties properties;

    @Test
    public void test() {
        System.out.println(stringify.apply(properties));
    }

    static Function<InfluxDBProperties, String> stringify = new Function<InfluxDBProperties, String>() {
        @Override
        public String apply(InfluxDBProperties influxDbProperties) {
            StringBuilder sb = new StringBuilder("InfluxDBProperties: [");

            sb.append("Url=").append(influxDbProperties.getUrl()).append(", ");
            sb.append("Database=").append(influxDbProperties.getDatabase()).append(", ");
            sb.append("Username=").append(influxDbProperties.getUsername()).append(", ");
            sb.append("Password=").append(influxDbProperties.getPassword()).append(", ");
            sb.append("RetentionPolicy=").append(influxDbProperties.getRetentionPolicy()).append(", ");
            sb.append("ConnectTimeout=").append(influxDbProperties.getConnectTimeout()).append(", ");
            sb.append("ReadTimeout=").append(influxDbProperties.getReadTimeout()).append(", ");
            sb.append("WriteTimeout=").append(influxDbProperties.getWriteTimeout()).append(", ");
            sb.append("GzipEnabled=").append(influxDbProperties.isGzip()).append("]");

            return sb.toString();
        }
    };
}

我有application.yml，以及application-test.yml和application-integrationTest.yml，如下所示：

spring:
  influxdb:
    url: http://localhost:8086
    username: admin
    password: adminPass
    database: integrationTest
    retention-policy: autogen
    connect-timeout: 10
    read-timeout: 30
    write-timeout: 10
    gzip: true

执行测试时，我得到以下异常：

在测试运行中，我应该更改哪些弹簧拾取配置？

Answer 1

将@SPringBootTest添加到您的测试中，

如果您不想要弹簧上下文加载，请参阅 Can I manually load @ConfigurationProperties without the Spring AppContext?

Spring @ConfigurationProperties绑定在测试中失败
