如何使用Spring注入keyvalue属性文件？ [英] How to inject a keyvalue properties file with Spring?

问题描述

我有一个keyvalue属性文件，其中包含错误代码及其错误消息。

I have a keyvalue properties file that contains error codes and their error messages.

我想在应用程序启动时注入此文件，以便我可以制作在不必读取文件的情况下查找注入的属性。

I'd like to inject this file on application startup, so that I can make lookups on the injected property without having to read the file.

以下只是伪代码， Spring中有什么东西那可以创建这个设置吗？

The following is just pseudocode, is there anything in Spring that could create this setup?

@Value(location = "classpath:app.properties")
private Properties props;

而app.properties包含：

whereas app.properties contains:

error1=test
error2=bla
...

如果没有，我怎么能在没有弹簧的情况下实现这个目标？

If not, how could I achieve this without spring?

推荐答案

感谢kocko的帮助，以下设置按预期工作，只有注释配置：

Thanks to the help of "kocko", the following setup works as expected, only annotation config:

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

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

或者，如果资源不应该作为bean提供，而只是在<$ c中加载$ c> @Component ：

Or if the resource should not be provided as a bean, but simply be loaded inside a @Component:

@Component
public class MyLoader {
    private Properties keys;

    @PostConstruct
    public void init() throws IOException {
        PropertiesFactoryBean bean = new PropertiesFactoryBean();
        bean.setLocation(new ClassPathResource("app.properties"));
        bean.afterPropertiesSet();
        keys = bean.getObject();
    }
}
