使用Mybatis时报错Invalid bound statement (not found):

使用逆向工程时生成的.xml文件在conf目录下，而使用查询方法时，无法在dao包下找到xml文件，所以报错。

测试代码如下所示：

@Test
    public void testSimple() throws IOException{
        SqlSessionFactory sqlSessionFactory = getSqlSessionFactory();
        SqlSession openSession = sqlSessionFactory.openSession();
        try{
            
            EmployeeMapper mapper = openSession.getMapper(EmployeeMapper.class);
            List<Employee> list = mapper.selectByExample(null);
            
            for(Employee employee : list){
                System.out.println(employee.getdId());
            }
            
        }finally{
            openSession.close();
        }
    }

报错信息如下所示：

解决办法就是找到自动生成的xml文件，并把它们复制到dao包下。
