EOS在JAVA代码中反射调用逻辑流

//逻辑流的返回值
String str = "";  
// 逻辑构件名称   
String componentName = "com.cn.test";   
//逻辑流名称
String operationName = "getNameById";
ILogicComponent logicComponent = LogicComponentFactory.create(componentName);
// 逻辑流的输入参数
DataObject dataObject =  DataObjectHelper.createDataObject(null);
dataObject.set("id", 111);
try {
  Object[] result = logicComponent.invoke(operationName, new Object[]{dataObject});
  if(result.length > 0){
    str =  result[0].toString();  
  }
} catch (Throwable e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}
