Question

这是我的application.yml文件：

server:
  port: 8089

schedulers:
  identity:
    origin: http://localhost:7189
    client-id: 72612d8e-b78e-446c-9397-354435696ec3
    secret: 173a7f6a-8263-11e7-bb31-be2e44b06b34
    username: integrationCLient
    password: P@ssword
    token-cache-backoff: 5
    default-token-cache-ttl: 5
    endpoints:
      validateToken: /v3/api/validateToken
      issueToken: /v3/api/oauth/v2/token
    httpClient:
      numOfRetries: 3
      backOffInMillis: 5
  couchbase:
    bootstrapHost: localhost
    bucket: default
    connectionTimeout: 1000

我正在尝试将文件读入我的Spring Boot应用程序。以下是相关代码：

@Configuration
@ConfigurationProperties(prefix = "schedulers")
@Getter
@Setter
public class CouchbaseConfig {

  CouchbaseContext couchbaseContext = new CouchbaseContext();

  @Bean
  public Bucket bucket() {
    System.out.println("askfjaslkfjafa" + couchbaseContext.getBootstrapHost());    //throws NPE
    CouchbaseEnvironment env =
        DefaultCouchbaseEnvironment.builder()
            .connectTimeout(Long.parseLong(couchbaseContext.getConnectionTimeout()))
            .build();
    Cluster cluster = CouchbaseCluster.create(env, couchbaseContext.getBootstrapHost());
    return cluster.openBucket(couchbaseContext.getBucket());
  }
}

这是我的CouchbaseContext.java文件：

导入lombok.Getter; 导入lombok.Setter;

@Getter
@Setter
public class CouchbaseContext {
    private String bootstrapHost;
    private String bucket;
    private String connectionTimeout;
}

我在尝试访问NPE中的couchbaseContext对象时遇到CouchbaseConfig.java。有人可以帮我解决我做错的事情吗？

Answer 1

@EnableConfigurationProperties({
    CouchbaseContext.class
})
@Configuration
public class CouchbaseConfig {

    @Bean
    public Bucket bucket(CouchbaseContext couchbaseContext) { ... }
}

此外，您可以在CouchbaseContext中删除@Configuration

无法使用@ Configuration.properties读取application.yml
