正在加载多个YAML文件（使用@ConfigurationProperties？）

Question

使用Spring Boot 1.3.0.Release

programs/program1.yml

name: Program 1
minDays: 4
maxDays: 6

@Configuration
@ConfigurationProperties(locations = "classpath:programs/program1.yml", ignoreUnknownFields = false)
public class ProgramProperties {

private Program test; //Program is a POJO with all the fields in the yml.
//getters+setters

编辑：一种工作方法是手动操作：

    private static final Yaml yaml = new Yaml(new Constructor(Program.class));
private static final ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();

try {
        for (Resource resource : resolver.getResources("/programs/*.yml")) {

            Object data = yaml.load(resource.getInputStream());

            programList.add((Program) data);
        }
    }
    catch (IOException ioe) {
        logger.error("failed to load resource", ioe);
    }

在Spring中，可以使用PropertySource注释加载多个配置属性文件，但不能加载YAML文件。参见以下链接中的26.6.4节：

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html#boot-features-external-config-typesafe-configuration-properties

然而，从您的问题，似乎您可以配置您的所有程序在单个YAML然后获得所有列表的程序在单个列表。

示例YAML（all.YAML）

programs:
  - name: A
    min: 1
    max: 2
  - name: B
    min: 3
    max: 4

config.java

@Configuration
@ConfigurationProperties(locations={"classpath:all.yaml"})
public class Config{

    private List<Program> programs;

    public void setPrograms(List<Program> programs) {
        this.programs = programs;
    }

    public List<Program> getPrograms() {
        return programs;
    }
}
