这是我的考试班.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
public class UserServiceImplIT {

    @Autowired
    private SampleService sampleService; 

    @BeforeClass
    public static void setUp() {
        System.out.println("-----> SETUP <-----");
    }

    @Test
    public void testSampleService() {
        assertTrue(true);
    }
}

我想在循环中执行一些阶段.我有Jenkinsfile

pipeline {
  agent any
  tools {}
  parameters {}
  environment {}
  stages {
    stage('Execute') {
      steps {
        script {
          for (int i = 0; i < hostnameMap.size; i++) {

            hostname = hostnameMap[i]
            echo 'Executing ' + hostname

            stage('Backup previous build ' + hostname) {
              backup(hostname, env.appHome)
            }


            stage('Deploy ' + hostname) {
              when {
                expression { env.BRANCH_NAME ==~ /(dev|master)/ }
              }
              steps {
                script {

我使用 Spring Boot 并希望提高性能。我必须在数据库中下载 50000 字段的文件。使用休眠。我在Batch inserts 中找到了解决方案。但我不知道如何从 crudrepository 获取 entitymanager

public interface MyRepository extends CrudRepository<OTA, Long>

application.yaml
                jdbc.batch_size: 50
                order_inserts: true
                order_updates: true
                cache.use_second_level_cache: true

我创建了 MyStorageService 并想保存我的文件：

@Service @Repository @Transactional public class MyStorageService {
    private MyRepository myRepository;

    private void insertAll(final List<MyFile> file) {
        myRepository.save(file.getListLine());
    } 

private void insert(final List<OTA> ota) {
    Session session = (Session) entityManager.getDelegate();

    Transaction tx = session.beginTransaction();

    for (int i = 0; i < ota.size(); i++) {
        session.save(ota.get(i));
        if (i % 50 == …

在spring boot 2(版本2.0.0.M7)项目中不能包含Prometheus指标.

据微米文档添加弹簧引导起动器的依赖,并在application.yaml加入management.endpoints.web.expose:普罗米修斯,但是打电话时/执行器/普罗米修斯 GET
{ "timestamp": 1518159066052, "path": "/actuator/prometheus", "message": "Response status 404 with reason \"No matching handler\"", "status": 404, "error": "Not Found" }

请告诉我为什么我没有获得prometheus指标？

我有控制器：

    @PostMapping(value = "/value/", consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
    public String updateSettings(final Dto dto) {
        System.out.println(">>> " + dto);
        return "template";
    }

如果我通过 Chrome 窗口发送请求，控制器就会工作。但是当我为这种方法编写测试时，我遇到了问题。未转换的对象，未插入值。

测试：

@Test
    @WithMockUser(username = FAKE_VALID_USER, password = FAKE_VALID_PASSWORD)
    public void test_B_CreateDtoWithValidForm() throws Exception {

        final Dto dto = new Dto();
               dto.setId("value");
               dto.setEnabled("true");

        this.mockMvc.perform(post(URL_SET_PROVIDER_SETTINGS)
                .contentType(MediaType.APPLICATION_FORM_URLENCODED_VALUE)
                .content(dto.toString()))
                    .andDo(print());
  }

输出是 >>> Dto{id=null,enabled=false}

如何在内容类型 application/x-www-form-urlencoded 中使用自定义对象测试 Post 请求？
