EL 会话对象属性

Question

${sessionScope.pricer.applicableRateCode}

---

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

---

javax.el.PropertyNotFoundException：在类型 com...ViewPrices 上找不到属性“applicableRateCode”

${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 ;
    }
}

Answer 2

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