一、问题描述

遇到一个问题，用maven配置的tomcat插件。tomcat7:run命令报错。但tomcat7:run-war却不会报错。

二、问题描述

项目为测试webservice的一个写法新建的。所以很简单

1、java代码

包括一个接口、一个实现类和一个测试类

//ReceiveClient 接口 package com.neo.deepwork.client; import com.neo.deepwork.server.ReceiveMsg; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class ReceiveClient { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext-client.xml"); ReceiveMsg receiveWsClient = context.getBean("receiveWsClient", ReceiveMsg.class); receiveWsClient.pringMsg("1234".getBytes()); } } //实现类 package com.neo.deepwork.server.impl; import com.neo.deepwork.server.ReceiveMsg; import javax.jws.WebService; @WebService public class ReceiveMsgImpl implements ReceiveMsg { @Override public void pringMsg(byte[] bytes) { String msg = new String(bytes); System.out.println(msg); } } //测试类 package com.neo.deepwork.server; import javax.jws.WebService; @WebService public interface ReceiveMsg { public void pringMsg(byte[] bytes); }

2、配置文件

包括三个配置文件 applicationContext.xml、applicationContext-client.xml和web.xml

4、项目结构图

三、执行及问题复现

1、tomcat7:run-war

执行tomcat7:run-war 执行结果成功再运行ReceiveClient中的main方法截图：浏览器访问：http://localhost:8070/services/receive?wsdl

2、tomcat7:run

执行tomcat7:run 执行结果失败再运行ReceiveClient中的main方法失败截图：控制台报错：
