Question

由于某些原因，Twilio SMS仅在here所示的公共静态void主要函数中工作。当我尝试将其移动到显示为here的JSF环境中时，它给我一个error并说“ NoClassDefFoundError”，这表示未在类路径中找到该类。奇怪的是，工作和不工作都在同一个项目中，这使我感到困惑。我不确定如何解决。

工作代码

package twilio;

import com.twilio.Twilio;
import com.twilio.type.PhoneNumber;
import com.twilio.rest.api.v2010.account.Message;

import javax.faces.bean.ManagedBean;

@ManagedBean
public class TwilioMSG {
    public static final String ACCOUNT_SID = "myAccSid";
    public static final String AUTH_TOKEN = "myAuth";

public static void main(String[] args) {
    Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
    Message.creator( new PhoneNumber("+myNumber"), new PhoneNumber("+TwilioNumber"), "I am having Java class").create();
    }
}

错误代码

package controllers;

import com.twilio.Twilio;
import com.twilio.rest.api.v2010.account.Message;
import com.twilio.type.PhoneNumber; 

import javax.faces.bean.ManagedBean;

@ManagedBean
public class PhoneController {
    public static final String ACCOUNT_SID = "myAccSid";
    public static final String AUTH_TOKEN = "myAuth";

    public PhoneController() {
    }

    public void testSMS(){
        Twilio.init(ACCOUNT_SID, AUTH_TOKEN);
        Message.creator( new PhoneNumber("+myNumber"), new PhoneNumber("+TwilioNumber"), "I am having OS class")
    }
}

我使用Glassfish作为服务器，使用IntelliJ只是为了获得更多信息

Answer 1

通常NoClassDefFound错误与运行时缺少库有关。

在您的情况下，可能是在本地设置中，将它放在类路径中，可以成功运行主方法。

现在，当转移到JSF环境时，您需要使用服务器，因此您必须注意以下几点：

依赖性JAR在服务器上的共享文件夹/类路径中可用吗？
该依赖关系是否随您的WAR或EAR打包在一起？

因此请解压缩并检查您的WAR并检查类路径以查看您的依赖项是否可用，并在类路径或WAR / EAR中提供它。

java.lang.NoClassDefFoundError：com.twilio.Twilio
