 </mule>

类(class)详情

 package org.Mule.transformers;
 import org.mule.api.MuleEventContext;
 import org.mule.api.MuleMessage;
 import org.mule.api.lifecycle.Callable;
 import org.mule.api.transformer.TransformerException;
 import org.mule.transformer.AbstractMessageTransformer;

 public class helloWorldComponent implements Callable{
 @Override
public Object onCall(MuleEventContext eventContext) throws Exception {

    eventContext.getMessage().setInvocationProperty("myProperty", "Hello    World!");
    return eventContext.getMessage().getPayload();
 }
}

详细信息是。

Caused by: org.springframework.beans.PropertyBatchUpdateException: Failed properties: Property 'objectClassName' threw exception; nested exception is java.lang.IllegalArgumentException: java.lang.ClassNotFoundException: Cannot load class 'org.Mule.transformers.helloWorldComponent'

Anypoint studio版本5.4.3

我刚刚关注了this链接仍然给出错误。

我刚刚尝试了您的流程，没有收到任何错误。我能想象的唯一原因是您的 Java 类 helloWorldComponent 的路径可能不正确。

致以诚挚的问候。
