Question

我需要模拟JdbcDaoImpl类来测试我的单元认证测试。我的WebSecurityConfigurerAdapter子类配置是

@Autowired
private AnalyticsUserDetailsService userDetailsService;

@Autowired
private DataSource dataSource;

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
    auth.jdbcAuthentication().dataSource(dataSource);
}

@Autowired
public void configureAuthentication(AuthenticationManagerBuilder authenticationManagerBuilder) throws Exception {
    authenticationManagerBuilder
            .userDetailsService(this.userDetailsService)
            .passwordEncoder(passwordEncoder());

    //this configuration is for checking app resources
    //this is not a regular authentication process
    //it will look for user in users and authorities table in db
    authenticationManagerBuilder.jdbcAuthentication().dataSource(dataSource);
}

我的测试课程：

@SpringBootTest(classes = SpringConfig.class)
@AutoConfigureMockMvc
@AutoConfigureWebMvc
@TestExecutionListeners(MockitoTestExecutionListener.class)
public class AuthenticationTest extends AbstractTestNGSpringContextTests{
    private static final String KNOWN_USER_MAIL = "valerian@mail.com";
    private static final String KNOWN_USER_PASSWORD = "pa$$w0rd";
    private static final String IN_MEMORY_KNOWN_USER_MAIL = "memuser";
    private static final String IN_MEMORY_KNOWN_USER_PASSWORD = "pass";

    @MockBean
    private AuthenticationUserService authenticationUserService;

    @Autowired
    private MockMvc mockMvc;


    @Test
    public void successLoginTest() throws Exception{
        Mockito.when(authenticationUserService.getUser(KNOWN_USER_MAIL)).thenReturn(createdUser(UserAccountRole.ROLE_SUPER));
        Answer<Collection<? extends GrantedAuthority>> answers = (invocationOnMock) -> getRoles();

        Mockito.when(authenticationUserService.getAuthorities(KNOWN_USER_MAIL)).thenAnswer(answers);
        ObjectMapper objectMapper = new ObjectMapper();
        JwtAuthenticationRequest loginInfo = new JwtAuthenticationRequest(KNOWN_USER_MAIL, KNOWN_USER_PASSWORD);

        MockHttpServletRequestBuilder requestBuilder = MockMvcRequestBuilders.post("/auth")
                .content(objectMapper.writeValueAsString(loginInfo));

        mockMvc.perform(requestBuilder).andExpect(MockMvcResultMatchers.status().isOk())
                .andExpect(MockMvcResultMatchers.cookie().exists(ACCESS_TOKEN));
    }
}

如果我从我的网络安全配置类中评论configureGlobal(AuthenticationManagerBuilder auth)方法和authenticationManagerBuilder.jdbcAuthentication().dataSource(dataSource)，则上述测试通过。但是，如果我取消注释代码，它会抛出异常。我如何模拟JdbcDaoImpl类，以便其loadUserByUsername(username)方法返回预期的用户而不是命中不可用的db。我试过了@MockBean JdbcDaoImpl jdbcDaoImpl，但它没有用。

org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

我如何使用mockito在测试中模拟JdbcDaoImpl
