我使用storm flux（0.10.0）dsl部署以下拓扑（简化为仅保留其相关部分）：

---
name: "my-topology"

components:
  - id: "esConfig"
    className: "java.util.HashMap"
    configMethods:
      - name: "put"
        args:
          - "es.nodes"
          - "${es.nodes}"

bolts:
  - id: "es-bolt"
    className: "org.elasticsearch.storm.EsBolt"
    constructorArgs:
      - "myindex/docs"
      - ref: "esConfig"
    parallelism: 1

# ... other bolts, spouts and streams here

如你所见，我用的一个螺栓是 org.elasticsearch.storm.EsBolt 其中包含以下构造函数（请参见代码）：

public EsBolt(String target) { ... }
public EsBolt(String target, boolean writeAck) { ... }
public EsBolt(String target, Map configuration) { ... }

最后一个应该被调用，因为我在constructorargs中传递了一个字符串和一个Map。但是，当我部署拓扑时，会出现以下异常，好像flux无法从类型（string，map）中推断出正确的构造函数：

storm jar mytopology-1.0.0.jar org.apache.storm.flux.Flux --local mytopology.yml --filter mytopology.properties

你知道会发生什么吗？下面是storm flux如何找到兼容的构造函数。魔法就在黑暗中 canInvokeWithArgs 方法。
以下是flux调试日志，您可以在其中看到fluxbuilder如何找到最合适的构造函数：
