HelloServiceImpl 类
package com.atguigu.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.atguigu.service.HelloService;

@Service
public class HelloServiceImpl implements HelloService {
@Override
public String sayHello(String name) {
return "hello-->" + name;
}
}
这是直接用的别人写好的模块 他运行正常 我一运行就报错 ，
Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:run (default-cli) on project dubbodemo_provider: Could not start Tomcat
去掉@Service注解tomcat又能正常启动
