我正在尝试使用该allowing方法来修复我的一个模拟对象上的方法的返回值。jdbc我在要允许的模拟对象上有以下方法：

List<T> query(String sql, RowMapper<T> rowMapper)

我正在使用with(any(RowMapper.class))，因为我真的不在乎RowMapper使用哪个 - 我只想确保当它query使用该 SQL 调用时它返回一个Listwith "bob"。

import java.util.Arrays;

import org.jmock.Expectations;
import org.jmock.Mockery;
import org.jmock.auto.Mock;
import org.jmock.integration.junit4.JUnitRuleMockery;
import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.jdbc.core.simple.SimpleJdbcOperations;

public class GetCustomersPhaseTest
{
    @Rule
    public final JUnitRuleMockery mockery = new JUnitRuleMockery();

    @Mock
    private SimpleJdbcOperations jdbc;

    @Mock
    private EventPublisher events;

    @Mock
    private Context context;

    private GetCustomersPhase phase;

    @Before
    public void setup()
    {
        phase = new GetCustomersPhase(jdbc, events);
    }

    @Test
    public void testGetCustomers()
    {
        mockery.checking(new Expectations() {
            {
                allowing(jdbc).query(with(equal("SELECT Name FROM Customers")), with(any(RowMapper.class)));
                will(returnValue(Arrays.asList("Bob")));
            }
        });

        phase.execute(context);
    }
}

然而，这给了我，

我查看了这个问题并试图解决这个问题，但我仍然无法让它工作。

SimpleJdbcOperations#query将 anObject...作为最终参数。发生错误是因为这不是由一个with方法来解释的，我认为这是因为这编译为将一个空数组传递给这个没有考虑到的方法。

如果你使用它会起作用，

allowing(jdbc).query(with(equal("SELECT Name FROM Customers")), with(any(RowMapper.class)), with(equal(new Object[0])));
will(returnValue(Arrays.asList("Bob")));

快速检查一下，你能确保你导入了正确的 with()、equalTo() 和 any() 方法吗？有时其他包也有类似的方法。
