set mock return value for any integer input parame

问题:

when(candidateService.findById(1)).thenReturn(new Candidate());

I want to extend this behaviour for any Integer(not necessarily for 1)

If I wrire

when(candidateService.findById( any(Integer.class)  )).thenReturn(new Candidate());

I have compilation error

The method findById(Integer) in the type CandidateService is not applicable for the arguments (Matcher)

UPDATE

imports:

import static org.junit.Assert.assertEquals;
import static org.mockito.Matchers.anyInt;
import static org.mockito.Matchers.anyString;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

import java.util.ArrayList;
import java.util.HashSet;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;

回答1:

Try anyInt():

when(candidateService.findById(anyInt())).thenReturn(new Candidate());

For example I have anyLong() in my project:

when(dao.getAddress(anyLong())).thenReturn(Arrays.asList(dto));

EDIT: You must import:

import static org.mockito.Matchers.anyInt;
