Question

标识符[＃]不是EL规范1.19节（标识符:: = Java语言标识符）所要求的有效Java标识符。可以通过设置系统属性

来禁用此检查

org.apache.el.parser.SKIP_IDENTIFIER_CHECK to true.

-im使用tomcat 8服务器。

这两个文件都保存了.xhtml

使用的bean：

import javax.faces.bean.ManagedBean;

@ManagedBean
public class Employee {
    private String name, id, healthPlanS;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getHealthPlanS() {
        return healthPlanS;
    }

    public void setHealthPlanS(String healthPlanS) {
        this.healthPlanS = healthPlanS;
    }

}

HealthPlan：

import javax.faces.bean.ManagedBean;

@ManagedBean
public class HealthPlan {

    private String planName, planPrice;

    public HealthPlan() {
    }

    public HealthPlan(String name, String price) {
        this.planName = name;
        this.planPrice = price;

    }

    public String getPlanName() {
        return planName;
    }

    public void setPlanName(String planName) {
        this.planName = planName;
    }

    public String getPlanPrice() {
        return planPrice;
    }

    public void setPlanPrice(String planPrice) {
        this.planPrice = planPrice;
    }

}

HealthPlanOption：

import java.util.ArrayList;

import javax.faces.bean.ManagedBean;

@ManagedBean
public class HealthPlanOptions {

    private ArrayList<HealthPlan> heathPlanArrayList;

    public HealthPlanOptions() {
        heathPlanArrayList = new ArrayList<HealthPlan>();

        heathPlanArrayList.add(new HealthPlan("Heath Care", "1555.5$"));
        heathPlanArrayList.add(new HealthPlan("Heath Care 2", "1959.10$"));

    }

    public ArrayList<HealthPlan> getHeathPlanArrayList() {
        return heathPlanArrayList;
    }

    public void setHeathPlanArrayList(ArrayList<HealthPlan> heathPlanArrayList) {
        this.heathPlanArrayList = heathPlanArrayList;
    }


}

Answer 1

哦，它现在有效。首先我有

<li>Monthly premium: #{healthPlanOption.price(#{healthPlanS})}</li>

导致同样的错误。第二个评论块。谢谢@balbus 你的野兽：）
