java - 如何使用 Spring 4 注入(inject)键值映射？

Question

VI=Visa
MC=Mastercard
...

我可以自动将其注入(inject) Map<String, String>与 Spring ？

喜欢:

@Resource("${myfile.properties}")
private Map<String, String> creditcards;

这可能吗？

Answer 1

发现一个不错的功能:

@Bean(name = "credit")
public PropertiesFactoryBean mapper() {
    PropertiesFactoryBean bean = new PropertiesFactoryBean();
    bean.setLocation(new ClassPathResource("credit.properties"));
    return bean;
}

将其注入(inject)到任何地方，如下所示:

@Resource(name = "credit")
private Properties credit;
