我最初是通過以下查詢獲得的List<Employee>：Query query = session.createQuery("select table1 from Table as table1");this.employees = (List<Employee>) query.list();這已成功呈現(xiàn)在以下數(shù)據(jù)表中：<p:dataTable var="employee" value="#{bean.employees}">    <p:column id="name" headerText="Name">        <h:outputText value="#{employee.name}" />    </p:column>    <p:column id="id" headerText="ID" >        <h:outputText value="#{employee.id}" />    </p:column></p:dataTable>但是，當(dāng)我嘗試從2個表中檢索它時，如下所示：Query query = session.createQuery("select a.name, b.id from Table1 as a, Table2 as b"); this.employees = (List<Employee>) query.list();它引發(fā)以下異常：java.lang.NumberFormatException: For input string: "name"    at java.lang.NumberFormatException.forInputString(Unknown source)    at java.lang.Integer.parseInt(Unknown source)    at java.lang.Integer.parseInt(Unknown source)    at javax.el.ArrayELResolver.toInteger(ArrayELResolver.java:166)    at javax.el.ArrayELResolver.getValue(ArrayELResolver.java:46)    ...這是怎么引起的，我該如何解決？
