当前使用版本(必填,否则不予处理)
3.4.3.2
该问题是如何引起的？(确定最新版也有问题再提!!!)
3.4.2升级到3.4.3.2
3.4.2可正常使用
重现步骤(如果有就写完整)
SqlSessionFactory用的MybatisSqlSessionFactoryBean、MybatisConfiguration
BaseMapper继承com.baomidou.mybatisplus.core.mapper.Mapper
接口：T selectOne(@Param("ew") Wrapper queryWrapper);
QueryWrapper queryWrapper = new QueryWrapper<>();
queryWrapper.eq("user_name", userName);
return Optional.ofNullable(userInfoMapper.selectOne(queryWrapper));

3.4.3.2取消了SelectOne注入,改成了default方法.
如果是自定义的BaseMapper就要去同步下逻辑或者自定义方法注入把SelectOne注入进去.
