我正在按照此链接中列出的示例添加自定义电子邮件通知。

在我的 maven 项目“ RegistryService ”中：我创建了 EmailTransformHandler 并使用 maven 创建了RegistryService-0.1.jar。我还GREG_HOME/repository/conf/axis2/axis2.xml通过添加处理程序来修改：

<handler name="EmailTransformHandler"
                 class="com.registration.example.service.EmailTransformHandler"/>

并将 RegistryService-0.1.jar 放入GREG_HOME/repository/components/dropins

package com.registration.example.service;

import java.util.ArrayList;

import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.xpath.AXIOMXPath;
import org.apache.axiom.soap.SOAPEnvelope;
import org.apache.axis2.AxisFault;
import org.apache.axis2.context.MessageContext;
import org.apache.axis2.engine.Handler;
import org.apache.axis2.handlers.AbstractHandler;

public class EmailTransformHandler extends AbstractHandler implements Handler {

    private String name;

    public String getName() {
        return name;
    }

    @Override
    public InvocationResponse invoke(MessageContext msgContext) throws AxisFault {
        if (msgContext.getTo() != null && msgContext.getTo().getAddress().startsWith("mailto:")) {
            try {
                SOAPEnvelope env = msgContext.getEnvelope();
                AXIOMXPath xPath = new AXIOMXPath("//ns:text");
                xPath.addNamespace("ns", "registry_example");
                OMElement element = (OMElement) ((ArrayList) xPath.evaluate(env)).get(0);
                element.setText(element.getText().replace("--", "This message intercepted by Terminator"));

            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return InvocationResponse.CONTINUE;
    }

}

当我转到 GREG_HOME/bin 并启动服务器时，出现以下异常：

我缺少什么配置？谷歌搜索这个错误不会产生任何相关结果（除了一些对我没有多大帮助的俄罗斯论坛）。我什至尝试通过 WSO2 管理控制台添加 jar 作为扩展，但我仍然得到这个异常。

根据错误，您的 RegistryService-0.1.jar 未正确设置为类路径。如果 jar 文件不是 OSGI 包，则应将 jar 文件放入“GREG_HOME/repository/components/lib”目录。
