ConfigurationProperties

list注入

config-test1:
  name: jack
  age: 18

config-test2:
  name:
    - jack
    - rose
    - peter

@Configuration
@ConfigurationProperties(value = "config-test1")
public class Config1 {

    private String name;
    private int age;

  // 省略getter/setter
}

@Configuration
@ConfigurationProperties(value = "config-test2")
public class Config2 {

    private List<Object> name;

  // 省略getter/setter
}

最后设置值是在
org.springframework.boot.context.properties.bind.Binder#bindObject
org.springframework.boot.context.properties.bind.Binder#findProperty

    private ConfigurationProperty findProperty(ConfigurationPropertyName name,
            Context context) {
        if (name.isEmpty()) {
            return null;
        }
        // 这里SpringIterableConfigurationPropertySource("classpath:/application.yml")会取到值
        ## org.springframework.boot.context.properties.source.SpringIterableConfigurationPropertySource#getCache
        for (ConfigurationPropertySource source : context.getSources()) {
            ConfigurationProperty property = source.getConfigurationProperty(name);
            if (property != null) {
                return property;
            }
        }
        return null;
    }
