在项目的.yml文件中添加以下内容.

In the .yml file of the project add below content.

spring:
  profiles:
    include:
      - currency

注意:如果需要，您可以通过这种方式引用多个.yml文件.您需要其他.yml文件和Config类，例如下面的示例.

Note: You can refer to multiple .yml files this way if you want. You need additional .yml files and Config classes like below example.

您需要另一个.yml文件，该文件是 application-currency.yml

You need to have another .yml file which is application-currency.yml

在application-currency.yml中，您可以添加如下所示的货币

In application-currency.yml you can add currencies, like below

currencies:
  mappings:
    USD:
      fraction: 2
      symbol: $
      text: "US Dollar"
    MXN:
      fraction: 2
      symbol: $
      text: "Mexican Peso"

您的配置类如下所示.

package com.configuration;

import com.Currency;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.stereotype.Component;

import java.util.Map;

@Component
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "currencies")
public class CurrencyConfiguration {

    private Map<String, Currency> mappings;

    public Map<String, Currency> getMappings() {
        return mappings;
    }

    public void setMappings(Map<String, Currency> mappings) {
        this.mappings = mappings;
    }
}

您需要使用可通过致电获得的货币详细信息，如下所示.

Wherever you need to use the currency details you can get by calling as shown below.

@Autowired
private CurrencyConfiguration currencyConfiguration;

String currencyCodeAlpha3 = "USD";
Currency currency = currencyConfiguration.getMappings().get(currencyCodeAlpha3);
