java.lang.NoClassDefFoundError: com.twilio.Twilio



由于某种原因，Twilio SMS仅在公共静态void主函数中工作，如下所示。当我尝试将其移动到此处显示的JSF环境时，它给我一个错误，说"NoClassDefFoundError"，这意味着在类路径中找不到该类。奇怪的是，工作和不工作的twilio都在同一个项目中，这让我感到困惑。我不确定如何解决它。

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();
    }
}

有错误的代码

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 作为我的服务器，而 IntelliJ 只是为了获得更多信息

通常NoClassDefFound错误与运行时缺少库有关。

在您的情况下，可能在本地设置中，您将它放在类路径中，成功运行您的 main 方法。

现在，当迁移到 JSF 环境时，您涉及一个服务器，因此您必须注意几件事：

  1. 依赖关系 JAR 在服务器上的共享文件夹/类路径上是否可用？
  2. 依赖项是按照您的 WAR 还是 EAR 打包的？

因此，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。
