javax.el.PropertyNotFoundException: Property 'applicableRateCode' not found on type com...ViewPrices

${sessionScope.pricer} 打印值但 applicableRateCode 不会打印

Answer 1

您需要向 ViewPrices 添加一个 getter 方法。 JSP EL 需要它们。

public class ViewPrices implements Cloneable, Serializable {    
    private static final long serialVersionUID = 1;
    // fields      
    private List<RateCode> applicableRateCode = null;

    public List<RateCode> getApplicableRateCode() {
       return applicableRateCode ;
    }
}
