Question

我想从 application.properties 和 bootstrap.yml 文件中选择值。当我尝试这样做时，我在控制台上得到Null。请在这里建议什么是错的。

application.properties 如下

restcall.erp.name=erp
restcall.plant.name=plant
restcall.apikey.name=apikey
restcall.region.name=region

bootstrap.yml 如下

apigee:
  api:
    key: someKey
  url:
    item:
      itemputurl: https://someAnotherUrl

** Java Code **

  package com.jci.itemjob.service.mapics;

import org.springframework.beans.factory.annotation.Value;


//@RefreshScope
@Component
//@Configuration
//@ComponentScan
@PropertySources({
    @PropertySource("classpath:application.properties"),
    @PropertySource("classpath:bootstrap.yml"),
})
public class MapicsSendAckToApigeeFromItemJob {


    @Value("${apigee.url.item.itemputurl}")
    private String itemPUTURL;

    @Value("${restcall.erp.name}")
    private String erpParam;

    @Value("${restcall.plant.name}")
    private String plantParam;

    @Value("${restcall.region.name}")
    private String regionParam;

    @Value("${restcall.apikey.name}")
    private String apiKeyParam;

    @Value("${restcall.params.key.headers}")
    private String headersParam;

    private static final Logger LOG = LoggerFactory.getLogger(MapicsSendAckToApigeeFromItemJob.class);

    public CloseableHttpResponse sendResponse(String apikey, String plant, String erp, String region,
            MapicsItemApigeePut itemApigeePut) {


        try {
            MultiValueMap<String, String> params = new LinkedMultiValueMap<String, String>();

            LOG.info("erp-----------------" + erpParam);
            LOG.info("plant-----------------" + plantParam);
            LOG.info("apikey-----------------" + apiKeyParam);
            LOG.info("region-----------------" + regionParam);
            LOG.info("itemPUTURL-----------------" + itemPUTURL);

            //Other Logic

输出如下

item-job-mapics_1  | 2018-02-05 09:02:35.381  INFO 1 --- [nio-9011-exec-3] j.i.s.m.MapicsSendAckToApigeeFromItemJob : erp-----------------null

我并不是说你需要做所有这些，但这就是我所做的......我创建了AppProperties类注释

@Component
@ConfigurationProperties(prefix="app")
@PropertySources({
    @PropertySource("classpath:application.properties")
//  @PropertySource("classpath:application-local.properties"),
//  @PropertySource("classpath:application-dev.properties"),
//  @PropertySource("classpath:application-prod.properties"),
})
public class AppProperties {

    @NotNull
    private String name;

}

在属性文件中我有app.name。

ConfigurationProperties在配置中定义您的前缀。 Spring可以自动找到你的属性文件，但我发现，当我有个人资料＆＃34; dev＆＃34;它只是在阅读application-dev.properties。使用@PropertySource("classpath:application.properties")，它会读取该文件+配置文件特定的一个（这是我正在寻找的东西）。

此外，我还有一个课程（空白）：

@Configuration
@EnableConfigurationProperties(AppProperties.class)
public class AppConfiguration {
}

无法从spring-boot中的Properties文件和Bootstrap.yml中选择值
