java - Spring Boot属性到对象

Question

我有以下配置

job:
  x:
    cron: 0 0 0 1,16 * ?
    group: xg
    name: xn
  y:
    cron: 0 0 1 1,16 * ?
    group: yg
    name: yn

还有像这样的 JAVA POJO

public class JobConfigProperties {
    private String group;
    private String name;
    private String cron;
    ...
}

I am looking for a way to let spring boot populate those classes

@LoadPropertiesAsObject(prefix="job.x") private JobConfigProperties jobXConfig; @LoadPropertiesAsObject(prefix="job.y") private JobConfigProperties jobYConfig;

@ConfigurationProperties 不起作用，因为它必须附加到类或方法

稍后编辑:似乎@ConfigurationProperties可以应用于方法。我会尝试一下并返回结果。

您可以通过配置类中的映射添加动态属性。键必须是字符串(属性键)，值可以是具有多个变量的复杂类。

@Component
@ConfigurationProperties("job")
public class JobConfigProperties {

  private Map<String, Intern> values;

  public Map<String, Intern> getValues() {
    return values;
  }
  public void setValues(Map<String, Intern> values) {
    this.values = values;
  }

  public static class Intern {

    private String cron;
    private String group;
    private String name;

    public String getCron() {
      return cron;
    }

    public void setCron(String cron) {
      this.cron = cron;
    }

    public String getGroup() {
      return group;
    }

    public void setGroup(String group) {
      this.group = group;
    }

    public String getName() {
      return name;
    }

    public void setName(String name) {
      this.name = name;
    }

  }

}

在您的示例中，您必须在“job”和动态变量之间放置一个“values”元素:

job:
  values: 
    x:
      cron: 0 0 0 1,16 * ?
      group: xg
      name: xn
    y:
      cron: 0 0 1 1,16 * ?
      group: yg
      name: yn
