SpringBoot+Mock Mvc测试web接口增删改查、导入导出

本文主要是介绍SpringBoot+Mock Mvc测试web接口增删改查、导入导出，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

需求：

        使用Mock Mvc单元测试web接口的增删改查、导入、导出功能，涵盖登录 token header赋值等全流程

1，引入核心依赖

<!-- 单元测试 --><dependency><groupId>junit</groupId><artifactId>junit</artifactId><scope>test</scope></dependency><dependency><groupId>org.mockito</groupId><artifactId>mockito-core</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework.security</groupId><artifactId>spring-security-test</artifactId><scope>test</scope></dependency>

2，编写登录抽象父类

@Component
public class AbstractControllerTest {private static final String USER_NO = "xxxx";private static final String PASSWORD = "xxxx";private static final String LOGIN_URL_DEV = ConstantsProperties.UAC_HOST+"/xxxx/auth/login";public static final String FILE_ROOT = System.getProperty("user.dir")+"/src/test/java/com/xxx/xxxx/controller/file";@Autowiredprivate WebApplicationContext webApplicationContext;@Autowiredprivate ApiGlobalVarsFilter apiGlobalVarsFilter;public MockMvc mockMvc;@AutowiredRestTemplate restTemplate;public String token;@Beforepublic void setupMockMvc(){//获取登录tokenLoginRequest request = new LoginRequest();request.setUserNo(USER_NO);request.setPassword(PASSWORD);ResponseEntity<LoginResponse> loginResponseResponseEntity =restTemplate.postForEntity(LOGIN_URL_DEV, request, LoginResponse.class);token = loginResponseResponseEntity.getBody().getToken();mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).apply(SecurityMockMvcConfigurers.springSecurity()).addFilters(apiGlobalVarsFilter).build();}}

3，编写单元测试核心类

@ActiveProfiles("dev")
@RunWith(SpringRunner.class)
@SpringBootTest(classes = YmsApplication.class)
@Slf4j
public class TCommTagConfigControllerTest extends AbstractControllerTest{@AutowiredTCommTagConfigService tCommTagConfigService;@Testpublic void login(){log.info("登录token为:{}",token);}@Testpublic void save() throws Exception {TCommTagConfigReqBody tCommTagConfigReqBody = new TCommTagConfigReqBody();tCommTagConfigReqBody.setTag("测试1");tCommTagConfigReqBody.setOwner("test");String requestBody = JSONUtil.toJsonStr(tCommTagConfigReqBody);mockMvc.perform(MockMvcRequestBuilders.post("/v1/tagConfig/save").contentType(MediaType.APPLICATION_JSON).content(requestBody).header("Authorization",token)).andDo(MockMvcResultHandlers.print());}@Testpublic void update() throws Exception {TCommTagConfigReqBody tCommTagConfigReqBody = new TCommTagConfigReqBody();tCommTagConfigReqBody.setId(62L);tCommTagConfigReqBody.setTag("测试11");tCommTagConfigReqBody.setOwner("test2");String requestBody = JSONUtil.toJsonStr(tCommTagConfigReqBody);mockMvc.perform(MockMvcRequestBuilders.post("/v1/tagConfig/save").contentType(MediaType.APPLICATION_JSON).content(requestBody).header("Authorization",token)).andDo(MockMvcResultHandlers.print());}@Testpublic void delete() throws Exception {String ids = "63,64";mockMvc.perform(MockMvcRequestBuilders.get("/v1/tagConfig/delete?ids="+ids).contentType(MediaType.APPLICATION_JSON).header("Authorization",token)).andDo(MockMvcResultHandlers.print());}@Testpublic void getList() throws Exception {TCommTagConfigPageReqBody tCommTagConfigPageReqBody = new TCommTagConfigPageReqBody();tCommTagConfigPageReqBody.setOwner("test");tCommTagConfigPageReqBody.setTag("测试");mockMvc.perform(MockMvcRequestBuilders.post("/v1/tagConfig/getList").contentType(MediaType.APPLICATION_JSON).content(JSONUtil.toJsonStr(tCommTagConfigPageReqBody)).header("Authorization",token)).andDo(MockMvcResultHandlers.print());}@Testpublic void exportFile() throws Exception {TCommTagConfigPageReqBody tCommTagConfigPageReqBody = new TCommTagConfigPageReqBody();tCommTagConfigPageReqBody.setIsExcel("1").setIsEmpty("0").setIsConfig("1");tCommTagConfigPageReqBody.setOwner("test");tCommTagConfigPageReqBody.setTag("测试");mockMvc.perform(MockMvcRequestBuilders.post("/v1/tagConfig/export").contentType(MediaType.APPLICATION_JSON).content(JSONUtil.toJsonStr(tCommTagConfigPageReqBody)).header("Authorization",token)).andDo(result -> {//保存为文件  文件目录需要自建File file  = new File(FILE_ROOT+"/tag/exportFile.xlsx");if(!file.exists()){file.createNewFile();}try(FileOutputStream fileOutputStream = new FileOutputStream(file)){IOUtils.write(result.getResponse().getContentAsByteArray(),fileOutputStream);}catch (IOException e){log.error("文件导出失败，异常信息:{}",e.getMessage());}//assertMatcherAssert.assertThat(file.exists(), Matchers.equalTo(true));MatcherAssert.assertThat(file.length(), Matchers.greaterThan(1024L));});}@Testpublic void importFile() throws Exception {//保存为文件  文件目录需要自建File file  = new File(FILE_ROOT+"/tag/Tag Config.xlsx");ResultActions resultActions = mockMvc.perform(MockMvcRequestBuilders.fileUpload("/v1/tagConfig/import").file(new MockMultipartFile("file", "Tag Config.xlsx","application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",new FileInputStream(file))).header("Authorization",token));MvcResult mvcResult = resultActions.andDo(MockMvcResultHandlers.print()).andExpect(MockMvcResultMatchers.status().isOk()).andReturn();String result = new String(mvcResult.getResponse().getContentAsByteArray(),"UTF-8");log.info("==========结果为：{}==========" ,result);}
}
