Java检索通用方法

Question

我试图将客户端bean传递给genericResponsor类。但它无法检索bean值。

主要课程

public Response searchClient(String json){
  //construct the receiver
  GenericReceiver<ClientBean> receiver = new GenericReceiver<ClientBean>();
  ClientBean clientbean = receiver.BeanReceiver(json, ClientBean.class);
  HeaderBean headerbean = receiver.HeaderReceiver(json);

  //process the data 
  ClientBean[] list = clientdao.searchclient(clientbean);

  //construct the responser
  GenericResponser<ClientBean> responser = new GenericResponser<ClientBean>();
  String Jsonbody = responsor.JsonResponse(clientbean, list, headerbean);
}

GenericResponser类它似乎有问题来检索clientBean.getCompanyId

public class GenericResponser <T>{
  public String JsonResponse( T bean,T[] list, HeaderBean headerbean) {
    String responsejson = ("{\"companyID\":\"" + bean.getCompanyId() + "\"}");
   }
}

在调试期间，我能够在GenericResponser中看到clientbean的所有值，但是无法使用并获取值。请帮助获取clientbean的值。

ClientBean类

public class ClientBean {
    private String companyId;
    private String branchId;

 public ClientBean () {
  super();
  this.companyId    = "";
  this.branchId = "";
 }

  public java.lang.String getCompanyId() {
    return FormUtil.returnString(companyId);
  }

  public java.lang.String getBranchId() {
    return FormUtil.returnString(branchId);
  }

  public void setCompanyId(java.lang.String newCompanyId) {
    companyId = FormUtil.returnString(newCompanyId);
  }
  public void setBranchId(java.lang.String newBranchId) {
    branchId = FormUtil.returnString(newBranchId);
  }

}

我这样做的目的是Generic，因为它可能会将其他bean传递给GenericResponser。
