我遇到的問題是：通過(guò) spring.profiles.active=development 在 application.properties 中定義的活動(dòng)配置文件。但是，當(dāng)我將 Spring 的環(huán)境變量用于 getActiveProfiles() 時(shí)，返回的只是一個(gè)空字符串?dāng)?shù)組。該應(yīng)用程序啟動(dòng)時(shí)顯示“以下配置文件處于活動(dòng)狀態(tài)：開發(fā)”。感謝對(duì)此的任何幫助。下面是一個(gè)簡(jiǎn)單的類，用于檢查我是否可以檢索配置文件。已經(jīng)嘗試自動(dòng)裝配環(huán)境變量無(wú)濟(jì)于事。此類標(biāo)有@Component 并實(shí)現(xiàn)了EnvirontmentAware。注意：我已經(jīng)查看了幾乎所有關(guān)于此問題的 SO 線程，所以請(qǐng)不要將其標(biāo)記為欺騙，因?yàn)闆]有一個(gè)解決了我的問題。@Overridepublic void setEnvironment(Environment environment) { this.environment = environment; System.out.println(environment.getActiveProfiles()[0]);}當(dāng)然，我們得到一個(gè)索引越界異常。application.properties（一些由于敏感信息而省略）spring.profiles.active=development主要類別：@SpringBootApplication@PropertySource("classpath:application.properties")@ComponentScan("uk.co.demo*")@Configurationpublic class EbecsIntegrationAdapterApplication {@Value("${activemq.broker_url}") private String amqBrokerUrl;@Value("${activemq.username}") private String amqUsername;@Value("${activemq.password}") private String amqPassword;@Value("${server.ssl.key-store}") private String amqKeystore;@Value("${server.ssl.key-store-password}") private String amqKeyStorePassword;@Beanpublic ConnectionFactory activemqConnectionFactory() throws Exception { ActiveMQSslConnectionFactory connectionFactory = new ActiveMQSslConnectionFactory(); connectionFactory.setBrokerURL(this.amqBrokerUrl + "? jms.prefetchPolicy.all=1"); connectionFactory.setUserName(this.amqUsername); connectionFactory.setPassword(this.amqPassword); connectionFactory.setTrustAllPackages(true); connectionFactory.setTrustStore(this.amqKeystore); connectionFactory.setTrustStorePassword(this.amqKeyStorePassword); connectionFactory.setKeyStore(this.amqKeystore); connectionFactory.setKeyStorePassword(this.amqKeyStorePassword); return new PooledConnectionFactory(connectionFactory);}

TA貢獻(xiàn)1877條經(jīng)驗(yàn) 獲得超1個(gè)贊
假設(shè)EbecsIntegrationAdapterApplication和TestEnv在同一個(gè)包中
省略不需要的注釋 @SpringBootApplication已經(jīng)是一個(gè)@Configuration組件，已經(jīng)加載了你的 application.properties 并且已經(jīng)是一個(gè)@ComponentScan
如果您需要掃描額外的包裹，您不應(yīng)該在包裹名稱的末尾添加 *。最好是堅(jiān)持使用引導(dǎo)結(jié)構(gòu)化代碼的最佳實(shí)踐
@SpringBootApplication
public class EbecsIntegrationAdapterApplication {
new TestEnv()在 main(args) 中刪除
Environment通過(guò)構(gòu)造函數(shù)注入自動(dòng)裝配
@Component
public class TestEnv {
private Environment environment;
public TestEnv(Environment environment) {
this.environment = environment;
printEnvs();
}
public void printEnvs() {
System.out.println(environment.getActiveProfiles()[0]);
}
}
