    public void setRateInCent(Integer rateInCent) {

    }

我的服务等级是

Set<RateTransmissionDetails> rateTrmDtls = new HashSet<RateTransmissionDetails>();
rateTrmDtls.add((new RateTransmissionDetails("A",new Integer(20)));

我收到错误

2012-11-02 16:44:02,796[http-6060-3] WARN duncansolutions.databus.external.controller.rate.RateController - 给调用者的错误消息：com.duncansolutions.databus.external.bean.hibernate.rate.RateTransmissionDetails不能转换为 java.lang.String

任何机构都可以告诉我如何去做。

Set<RateTransmissionDetails> rateTrmDtls = new HashSet<RateTransmissionDetails>(); 
rateTrmDtls.add(new RateTransmissionDetails("A",new Integer(20)));

这里没有错。当您使用该集合rateTrmDtls做某事时，可能会发生该错误，并且代码需要一组String

你能显示你在哪里使用集合的代码RateController吗？
