[网络协议]java.lang.IllegalArgumentException: An operation with name [{X}count] already exists in this service

尝试编写webservice的服务端时遇到报错：

Exception in thread “main” java.lang.IllegalArgumentException: An operation with name [{http://service.demo.example.com/}count] already exists in this service
完整报错如下：

Exception in thread "main" java.lang.IllegalArgumentException: An operation with name [{http://service.demo.example.com/}count] already exists in this service

检查半天后发现似乎是mybatisplus与webservice起冲突了

报错代码：

package com.example.demo.service;

import com.baomidou.mybatisplus.extension.service.IService;
import com.example.demo.domain.UserDO;
import javax.jws.WebService;

@WebService
public interface UserService extends IService<UserDO> {
    String test(String name);
}

package com.example.demo.service.serviceimpl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.example.demo.dao.UserDao;
import com.example.demo.domain.UserDO;
import com.example.demo.service.UserService;

public class UserServiceimpl extends ServiceImpl<UserDao, UserDO>  implements UserService {

    @Override
    public String test(String name){
        return name+",你好";
    }
}

去除mybatisplus后不再报错的代码

package com.example.demo.service;

import com.baomidou.mybatisplus.extension.service.IService;
import com.example.demo.domain.UserDO;
import javax.jws.WebService;

@WebService
//public interface UserService extends IService<UserDO> {
public interface UserService{
    String test(String name);
}

package com.example.demo.service.serviceimpl;

import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.example.demo.dao.UserDao;
import com.example.demo.domain.UserDO;
import com.example.demo.service.UserService;

//public class UserServiceimpl extends ServiceImpl<UserDao, UserDO>  implements UserService {
public class UserServiceimpl implements UserService {

    @Override
    public String test(String name){
        return name+",你好";
    }
}
