会有以下警告在生成wsdl时候：
The service class "test.DbconnMysql" does not comply to one or more requirements of the JAX-RPC 1.1 specification, and may not deploy or function correctly.
The method "getConnection" on the service class "test.DbconnMysql" uses a data type, "java.sql.Connection", that is not supported by the JAX-RPC specification. Instances of the type may not serialize or deserialize correctly. Loss of data or complete failure of the Web service may result.应该如何处理，谢谢！
