SpringBootApplication 不识别属性配置 [英] SpringBootApplication does not recognize properties configuration

问题描述

我在 psn.stats.config

@Configuration
@PropertySource("classpath:/api.properties")
public class AppConfig {

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }
}

我的 main 位于 psn.stats 包中，如下所示:

My main is in package psn.stats and looks like this:

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class StatsServiceApplication {

    public static void main( String[] args ) {
        SpringApplication.run( StatsServiceApplication.class, args );
    }
}

现在我想使用 psn.stats.connectors 包中的服务类中的属性值.这门课在这里:

Now I want to use properties values in on of the service class from package psn.stats.connectors. This class is here:

@Component
public class SomeAPIConnector {

    @Value( "${some.data.token.header}" )
    private String tokenHeader;
    @Value( "${some.data.token.value}" )
    private String token;
    @Value( "${some.data.api.address}" )
    private String apiAddress;
}

但是当我运行这个应用程序时，上面的所有字段都是空的.我不知道为什么 SpringBoot 不读取带有属性文件的配置.你能帮我吗?

But when I run this app, all above fields are null. I don't know why SpringBoot does not read configuration with properties file. Can you help me with it?

推荐答案

spring boot 中不需要添加@PropertySource("classpath:/api.properties") 只需要在src/main/resources中创建一个application.propertiesspring boot 将获取所有属性，您可以在 SomeAPIConnector 中使用它们，

In spring boot it is not necessary to add @PropertySource("classpath:/api.properties") only create an application.properties in src/main/resources spring boot will get all the properties and you can use them in SomeAPIConnector,

在 src/main/resources应用程序属性内容可能是:

In src/main/resources application.properties the content could be:

some.data.token.header = XYZ

some.data.token.header = XYZ
