具有多操作合约的WCF Rest服务

我想用这样的操作契约创建WCF Rest服务

public interface ICustomerService  
{  
    [OperationContract]
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json,  
            ResponseFormat = WebMessageFormat.Json, UriTemplate = "/GetAllCustomer/")]  
    List<CustomerDataContract> GetAllCustomer();  

    [OperationContract]
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json,  
            ResponseFormat = WebMessageFormat.Json, UriTemplate = "/GetSTOCK/ABC")]  
    List<CustomerDataContract> GetSTOCK();  

    [OperationContract]
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Json,  
            ResponseFormat = WebMessageFormat.Json, UriTemplate = "/GETSUPINFO/XYZ/ABC")]  
    List<CustomerDataContract> GETSUPINFO();   
} 

有人能帮忙吗?
