java - Spring Boot 自定义属性

Question

在我的项目中有 2 个资源属性
1. application.properties

server.port=8002

spring.data.mongodb.host=
spring.data.mongodb.port=
spring.data.mongodb.database=
spring.data.mongodb.username=
spring.data.mongodb.password=

2. application-development.properties

server.port=8002

spring.data.mongodb.host=
spring.data.mongodb.port=
spring.data.mongodb.database=
spring.data.mongodb.username=
spring.data.mongodb.password=

spring.data.solr.host

这个类使用了 development 的 value 属性

@Configuration
@EnableSolrRepositories(basePackages = {
    "id.alfadigital.alfagift.service.product.v1.db.solr.repository",
    "id.alfadigital.alfagift.service.product.v2.db.solr.repository"
})
public class SolrConfiguration {

  @Value("${spring.data.solr.host}")
  private String solrUrl;

  @Bean
  public SolrClient solrClient() {
    return new HttpSolrClient.Builder(solrUrl).build();
  }

  @Bean
  public SolrTemplate solrTemplate(SolrClient client) {
    return new SolrTemplate(client);
  }
}

I use application-development.properties as my project resoure

所以我使用以下命令运行项目: mvn spring-boot:run -D spring.profiles.active=development但是当我运行项目时附加了一个错误

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'solrConfiguration': 
           Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: 
           Could not resolve placeholder 'spring.data.solr.host' in value "${spring.data.solr.host}"
Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.data.solr.host' in value "${spring.data.solr.host}"

我很困惑，我的错误在哪里，我该怎么办？

您能否使用以下命令运行您的应用程序。由于错误使用命令它无法拿起development轮廓。mvn spring-boot:run -Dspring.profiles.active=development例子:
