首先先建好一个pojo类,

public class IcWsprice implements Serializable
{

??? /**
???? *
???? */
??? private static final long serialVersionUID = 1L;

??????? // primary key
??? private java.util.Calendar icEffdate;

??? private java.lang.String icCode;

??? private java.lang.String icArea;

??? // fields
??? private java.lang.Integer icOWp;

??? private java.lang.Integer icWp

???? ..............

}

在hibernate 中mapping
