您可以使用ldif文件为测试定义嵌入式ldap服务器，如下所示：

spring.ldap.embedded.ldif=classpath:test-server.ldif
spring.ldap.embedded.base-dn=dc=springframework,dc=org
spring.ldap.embedded.port=8389

在测试中，您可以尝试像在正常流中一样对特定用户进行身份验证：

@SpringBootTest
@AutoConfigureMockMvc
@TestPropertySource(properties = {
        "spring.ldap.embedded.ldif=classpath:test-server.ldif",
        "spring.ldap.embedded.base-dn=${spring.ldap.base}",
        "spring.ldap.embedded.port=8389",
        "spring.ldap.embedded.url=ldap://localhost:8389/",
        "spring.ldap.embedded.credential.username=uid=admin",
        "spring.ldap.embedded.credential.password=secret",
        "spring.ldap.embedded.validation.enabled=false",
        "spring.ldap.urls=ldap://localhost:8389/",
        "spring.ldap.username=uid=admin",
        "spring.ldap.password=secret"})
public class AuthenticatingLdapApplicationTests {
    @Autowired
    private MockMvc mockMvc;

    @Test
    public void loginWithValidUserThenAuthenticated() throws Exception {
        FormLoginRequestBuilder login = formLogin()
            .user("user")
            .password("userpassword");

        mockMvc.perform(login)
            .andExpect(authenticated().withUsername("user"));
    }

    @Test
    public void loginWithInvalidUserThenUnauthenticated() throws Exception {
        FormLoginRequestBuilder login = formLogin()
            .user("invalid")
            .password("invalidpassword");

        mockMvc.perform(login)
            .andExpect(unauthenticated());
    }
}
