总之mybatis-spring：如果使用了2.0.5版本就不行，比如下面的代码就会报错，但是如果高于2.0.5版本就没问题：

@SpringBootTest
class MockTest {

    @SpyBean
    private UserService userService;

    @SpyBean
    private UserMapper userMapper;

    @Test
    void currTest() {
        Mockito.doReturn(new User().setId(100L).setName("ddd").setPassword("mmm")).when(userMapper).findByNameAndPassword("w.dehai", "123456");
        User login = userService.login("w.dehai", "123456");
        System.err.println(login);
    }

}
