これは、2 つのメソッドを実行する私のコードです。
<h:panelGroup> <br /><br />
<h:outputLabel id="yearLbl" value="Year:" />
<h:outputLabel id="selectType" /><br />
<h:selectOneMenu id="type" value="#{clController.type}">
<f:selectItem itemValue="2013" itemLabel="2013" />
<f:selectItem itemValue="2012" itemLabel="2012" />
<f:selectItem itemValue="2011" itemLabel="2011" />
<f:selectItem itemValue="2010" itemLabel="2010" />
<f:selectItem itemValue="2009" itemLabel="2009" />
<f:selectItem itemValue="2008" itemLabel="2008" />
</h:selectOneMenu>
<h:commandButton type="submit" onclick="#{clController.getTotal(clController.type)}" action="#{clController.getPaymentByMonth(clController.type)}" id="stateInfo" value="Show Monthly " >
</h:commandButton>
</h:panelGroup>
呼び出される関数は次のとおりです。
public DataModel getPaymentByMonth(String year) {
this.session = HibernateUtil.getSessionFactory().getCurrentSession();
List<CustomerPayment> paymentList = null;
try {
org.hibernate.Transaction tx = session.beginTransaction();
Query q = session.createQuery("from CustomerPayment where DATE like '%" + year + "'");
paymentList = (List<CustomerPayment>) q.list();
} catch (Exception e) {
e.printStackTrace();
}
return paymentDataModel = new ListDataModel(paymentList);
}
public DataModel getTotal(String year) {
this.session = HibernateUtil.getSessionFactory().getCurrentSession();
List<CustomerPayment> total = null;
try {
org.hibernate.Transaction tx = session.beginTransaction();
System.out.println(year);
Query q = session.createQuery("select c.type, c.date, sum(c.amount) from CustomerPayment c where c.date LIKE '%"+year+"' group by c.type");
System.out.println("select c.type, c.date, sum(c.amount) from CustomerPayment c where c.date LIKE '%"+year+"' group by c.type");
total = (List<CustomerPayment>) q.list();
} catch (Exception e) {
e.printStackTrace();
}
return totalDataTable = new ListDataModel(total);
}
問題は、次のエラーが発生することです。
java.lang.NumberFormatException: For input string: "type"
タイプは年を意味しますが、それでエラーが発生します。画面にタイプを印刷すると、ex 2013 が印刷されます。なぜこのエラーが発生するのですか?
