${sessionScope.pricer.applicableRateCode}

---

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

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

${sessionScope.pricer}打印值，但ApplicatableRateCode不会打印

Answer 1

您需要将getter方法添加到ViewPrices。JSPEL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 ;
    }
}

Answer 2

类中缺少Setter/Getter。JSTLEL将使用标准访问器方法访问属性
