springboot2 中Druid和ibatis（baomidou） 遇到org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.iflytek.pandaai.service.multi.mapper.TanancyMapper

调用mapper中任何方法都会出现类似的错误

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.iflytek.pandaai.service.multi.mapper.TanancyMapper.insert

检查 是否是有申明 SqlSessionFactory的bean，例如：

@Bean(name = "DruidsqlSessionFactory")
    @Primary
    public SqlSessionFactory getSessionFactory(DruidDataSource dataSource) throws Exception {
        SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
        factoryBean.setDataSource(dataSource);
        return factoryBean.getObject();
    }

而该类和另外的SqlSessionFactory冲突，

解决办法：

1、在注解中申明要用的sqlSessionFactory bean名称

@MapperScan(basePackages = {"com.iflytek.pandaai.service.**.mapper"}, sqlSessionFactoryRef = "sqlSessionFactory")
