Java 映射的配置属性

我的spring boot yaml文件中有以下结构：

countryConfiguration:
  NL:
    address:
      postcodeKeyboardType: ALPHANUMERIC
      postcodeExample: 1111 AA
      cityExample: Amsterdam
  ES:
    address:
      postcodeKeyboardType: NUMERIC
      postcodeExample: 11111
      cityExample: Madrid

我想创建一个配置属性类来访问这些值。我有这样的想法：

@Configuration
@ConfigurationProperties
@Validated
public class CountryConfigurationProperties {

    @NotNull
    private Map<String, Configuration> countryConfiguration;

    public Map<String, Configuration> getCountryConfiguration() {
        return countryConfiguration;
    }

    public void setCountryConfiguration(Map<String, Configuration> 
countryConfiguration) {
        this.countryConfiguration = countryConfiguration;
    }

    public static class Configuration {
        private Object address;

        public Object getAddress() {
            return address;
        }

        public void setAddress(Object address) {
            this.address = address;
        }
    }


}

如果我删除静态内部类配置，并放入对象，它就会工作…

我注意到地址字段的类型为

对象

。我希望它是

Address

类型，并且有一个表示Address对象的内部类

在下面的代码片段中，我添加了一个Address类来匹配您正在使用的yml配置。我已经测试了它，它成功地启动并相应地映射属性
