Java 如何在Spring yml中注入具有相同属性的类？

我想配置3个线程池参数，所以我在配置中写入了vale。如何将它们注入Springbean。这是我的yml文件配置

spring: 
  threadpool:
    pool1:
      corePoolSize: 1
      maxPoolSize: 10 
    pool2:
      corePoolSize: 2
      maxPoolSize: 20
    pool3:
      corePoolSize: 3
      maxPoolSize: 30

这是豆子，对吗

@ConfigurationProperties(prefix = "spring.threadpool")
public class PoolConfig { 
public  class CommonPool  {
    public int getCorePoolSize() {
        return corePoolSize;
    }
    public void setCorePoolSize(int corePoolSize) {
        this.corePoolSize = corePoolSize;
    }

    public int getMaxPoolSize() {
        return maxPoolSize;
    }

    public void setMaxPoolSize(int maxPoolSize) {
        this.maxPoolSize = maxPoolSize;
    } 
    int corePoolSize;
    int maxPoolSize; 
} 
public   class Pool1 extends CommonPool     {  } 
public   class Pool2 extends CommonPool     {  } 
public   class Pool3 extends CommonPool     {  } 
}

在另一个bean中，我尝试获取每个pool参数，如poolConfig.Pool1，但我不能这样做，如何修复它

 @Autowired
 PoolConfig poolConfig;

我想你可以这样做

@ConfigurationProperties
public class PoolConfig() {
   private CommonPool pool1;
   private CommonPool pool2;
   private CommonPool pool3;
   // getter, setter,  ...

   public static class CommonPool() {
      private int corePoolSize;
      private int maxPoolSize;
      // getter, setter, ...
   }
}

我个人建议使用列表。你的yml应该是这样的

spring: 
  threadpool:
    - poolName: pool1
      corePoolSize: 1
      maxPoolSize: 10 
    - corePoolSize: 2
      poolName: pool2
      maxPoolSize: 20
    - poolName: pool3
      corePoolSize: 3
      maxPoolSize: 30

您的PoolConfig类应该是

@ConfigurationProperties
public class PoolConfig() {
   private List<CommonPool> pools;
   // getter, setter,  ...

   public static class CommonPool() {
      private String poolname;
      private int corePoolSize;
      private int maxPoolSize;
      // getter, setter, ...
   }
}

@ConfigurationProperties
公共类PoolConfig（）{
私人名单池；
//getter，setter。。。
公共静态类CommonPool（）{
私有字符串池名；
私有池大小；
私有int-maxPoolSize；
//getter，setter。。。
}
}
