java - Spring 启动: How to get program args with ConfigurationProperties

Question

当我启动我的应用程序时，我试图从命令行获取一些属性。我确实尝试了很多解决方案，但没有任何效果。我只会使用@Value作为最后的解决方案

java -jar myjar.jar --test.property=something

这里有一些类(class)

Main class

@SpringBootApplication
public class TestApplication {

    public static void main(String[] args) {
        SpringApplicationBuilder builder = new SpringApplicationBuilder(TestApplication.class);
        builder.run(args);
    }
}

Config class

@Configuration
@EnableConfigurationProperties(StringProperties.class)
public class StringConfiguration {

    @Autowired
    private StringProperties stringProperties;

    @Bean(name = "customBeanName")
    public List<String> properties() {
        List<String> properties = new ArrayList<>();

        properties.add(stringProperties.getString());

        return properties;
    }
}

Properties class

@Component
@ConfigurationProperties("test")
public class StringProperties {

    private String property;

    public String getString() {
        return property;
    }
}

Ops.....我已经测试了你的代码。它是 StringProperties 中缺少的 setProperty。

 public void setProperty(String property) {
        this.property = property;
    }
