mybatis-plus springboot无法创建bean

发布时间 2023-06-30 21:53:56作者: 小白的进阶之旅

在学习尚硅谷的mybatis-plus中，发现依托代码无法创建userMapperbean，在网上找了各种办法，终于是找到了一个大无语的办法。

只要将springboot的版本主动降到2.x.x之后便可以创建。可能mp是国人写的目前对springboot3.x.x并没有做适配，但是更进一步的方法正在思想中。

package com.example.bootMp;

import com.example.bootMp.mapper.UserMapper;
import com.example.bootMp.pojo.User;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import java.util.List;

@SpringBootTest
public class MybatisPlusTest {
    @Autowired
    private UserMapper userMapper;
    @Test
    public void testSelectList(){
        List<User> users = userMapper.selectList(null);
        users.forEach(System.out::println);
    }
}
