測試

@SpringBootTest
@AutoConfigureMockMvc
class BasicAuthApplicationTests {


	@Autowired
	private MockMvc mockMvc;


	@Test
	void shouldReturnDefaultMessage() throws Exception {

		MvcResult mvcResult = mockMvc
				.perform(get("/hello").with(httpBasic("user","user")))
				.andReturn();

		System.out.println(mvcResult.getResponse().getContentAsString());
	}


}
