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com。上找不到属性'applicableRateCode'。 .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 ;
    }
}

Answer 2

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