我们有一个带有多个if条件（实际代码有超过100个if条件）的java代码，可以根据操作名调用适当的方法。如何以更有效的方式重构？

if ("Customer".equals(header.getString(OPERATION))) 
    CustomerRequest searchRequest = gson.fromJson(paylaod, CustomerRequest.class);
    response = viewCustomerServiceEndpoint.viewCustomer(searchRequest, pool);
  }
  if ("ProfileUpdate".equals(header.getString(OPERATION))) {
    ProfileUpdateRequest searchRequest = gson.fromJson(paylaod, ProfileUpdateRequest.class);
    response = saProfileUpdateEndPoint.saProfileUpdate(searchRequest, pool);
  }
