mockito on jdbcTemplate throwing compilation error

I am trying to mock jdbcTemplate to throw an exception.

I am trying to throw exception on this method on JdbcTemplate

<T> List<T> query(String sql, Object[] args, RowMapper<T> rowMapper)

Here is what I have

@MockBean
JdbcTemplate jdbcTemplate;

Mockito.doThrow(exception).when(jdbcTemplate.query(anyString(), anyList(), any(MyMapper.class)));

I get compilation error, cannot resolve method. I also tried

Mockito.doThrow(exception).when(jdbcTemplate.query(anyString(), anyList(), Matchers.<RowMapper<MyMapper>>any()));

but still get same error.

what is the right way to do it here?

EDIT

As suggested in one of the answers, I tried

 Mockito.doThrow(exception).when(jdbcTemplate).query(anyString(), anyList(), any(MyMapper.class));

I still get cannot resolve the method error.

The following calls will compile:

Mockito.doThrow(exception).when(jdbcTemplate).query(
    Mockito.anyString(), 
    Mockito.any(Object[].class), 
    Mockito.any(MyMapper.class)
);

Mockito.doThrow(exception).when(jdbcTemplate).query(
    Mockito.anyString(), 
    Mockito.any(Object[].class), 
    ArgumentMatchers.<RowMapper<MyMapper>>any())
);

The key difference between these and what you had tried previously is the second argument. In this method:

<T> List<T> query(String sql, Object[] args, RowMapper<T> rowMapper) throws DataAccessException;

... the second argument is:

Object[] args

It looks like you were matching this with anyList() which returns List<T>. Since this parameter is of type Object[] it should be matched with something which returns an Object[]. For example:

Mockito.any(Object[].class)

Try:

Mockito.doThrow(exception).when(jdbcTemplate).query(anyString(), anyList(), any(MyMapper.class));

The when() call is to wrap your mock; you don't call your method within the when() call you do it after that wrapping to indicate to Mockito what you are expecting to happen to it.
