在Spring Boot中从属性文件注入值数组

您需要设置 属性前缀 ，不需要 @Configuration 和 @Component， 并使用嵌入式 公共静态类 包装货币的属性

 @PropertySource("classpath:config.properties") @ConfigurationProperties(prefix = "market") @Validated public class MarketConfig {      List<MarketCurrency> currs;      //getters setters      public static class MarketCurrency {          String name;          String symbol;        ....//getters setters

将MarketConfig.class添加到@EnableConfigurationProperties

 @SpringBootApplication @EnableSwagger2 @EnableConfigurationProperties({MarketConfig.class}) public class MarketApplication implements CommandLineRunner {    private final MarketService service;    private final MarketConfig config;    public MarketApplication(MarketService service, MarketConfig config) {       this.service = service;       this.config = config;    }
