同僚、私は、JavaベースのSpringの設定があります。Springベースのアプリケーションを実行するとプレースホルダを解決する方法は？
@Configuration
@EnableTransactionManagement
@ComponentScan (basePackages = {"com.abc.dirint"})
@PropertySource("classpath:/settings/${env}/dir.properties")
@EnableScheduling
public class DirConfig {
private static final Logger log = LoggerFactory.getLogger(DirConfig.class);
@Autowired
private Environment environment;
@Bean
public static PropertySourcesPlaceholderConfigurer propertyConfigInDev() throws IOException {
PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
propertySourcesPlaceholderConfigurer.setIgnoreUnresolvablePlaceholders(true);
return propertySourcesPlaceholderConfigurer;
}
/*Beans follow...*/
}
私はmvn clean package -Denv=devを実行すると、それはテストを実行し、エラーなしでプロジェクトをビルドします。
コンパイル済みのjarを実行します。 次の第スタックトレースで（これは期待されている）私はjava -jar dir-integration-1.2-SNAPSHOT.jar -Denv=devを実行し、プログラムが失敗します。
Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.abc.dirint.DirConfig]; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'env' in string value "classpath:/settings/${env}/dir.properties"
at org.springframework.context.annotation.ConfigurationClassParser.parse(ConfigurationClassParser.java:180)
Wnen私は$ java -jar dir-integration-1.2-SNAPSHOT.jar --env=devを実行結果は次である：

私はからプロパティを受け取るために何をすべきアプリケーションの実行中に指定されたプロパティファイル？ java -h
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
...
-D<name>=<value>
set a system property
