Question

好的，我经历了很多答案，但我的问题仍然没有解决。我正在尝试测试我的控制器 -

@Controller
@Produces(MediaType.APPLICATION_JSON)
@RequestMapping(value = "/verify/email")
public class EmailController {

@Autowired
private ByEmail strategy;

@Autowired
private ApplicationConfig config;

@ResponseBody
@RequestMapping(method = RequestMethod.POST, produces = 
MediaType.APPLICATION_JSON)
public Request newRequest(@RequestBody VRequest request) throws 
IOException {
    log.info(request.toString());
    System.out.println(request.toString());
    request.setType(VType.EMAIL);
    Optional<Request> response = strategy.processRequest(request);
    return response.orElseThrow(BadRequestException::new);
}

我的测试是 -

@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
@WebAppConfiguration
@SpringBootTest
public class TestEmailController {

@Mock
private ByEmail strategy;

@InjectMocks
@Autowired
private EmailController controller;

@Autowired
private MockMvc mockMvc;

@Test
public void contexLoads() throws Exception {
    assertThat(controller).isNotNull();
}

当我尝试运行测试时，它会发出以下错误 -

这是我的ApplicationTest类 -

 @RunWith(SpringRunner.class)
    @SpringBootTest
    public class ApplicationTests {

    @Test
    public void contextLoads() {
    }

}

这是我的ApplicationConfig类 -

@Data
@Configuration
@EnableAutoConfiguration
@ConfigurationProperties(prefix = "company.services.verification")
public class ApplicationConfig {

@NotNull
String smstype;

@NotNull
String fromEmail;

@NotNull
String subjectEmail;

@NotNull
String subjectManual;

@NotNull
List<Integer> countries;

@NotNull
String redirectUrl;
}

我的application.yaml文件中定义了abover属性 -

company:
    services:
      verification:
        smstype: Claims
        fromEmail: noreply@company.com
        subjectEmail: Email Verification
        subjectManual: Claim Initiated
        redirectUrl: http://www.google.com
        countries:
         - 1
         - 2
         - 3
         - 4

我经历了很多答案，但错误仍然是一样的。我使用的是spring-boot 1.5.6。有什么帮助吗？

Answer 1

尝试使用此application.yaml，验证部分后所有属性只需一个标签。

company:
    services:
      verification:
        smstype: Claims
        fromEmail: noreply@company.com
        subjectEmail: Email Verification
        subjectManual: Claim Initiated
        redirectUrl: http://www.google.com
        countries:
          - 1
          - 2
          - 3
          - 4

选项2：而不是.yaml使用application.propterties在application.propterties文件夹中创建resources文件，内容应如下所示：

company.services.verification.smstype: Claims
company.services.verification.fromEmail: noreply@company.com
company.services.verification.subjectEmail: Email Verification
company.services.verification.subjectManual: Claim Initiated
company.services.verification.redirectUrl: http://www.google.com
company.services.verification.countries[0]: 1
company.services.verification.countries[1]: 2
company.services.verification.countries[2]: 3
company.services.verification.countries[3]: 4

配置类的示例

@Configuration
@ConfigurationProperties(prefix = "company.services.verification")
public class MyConfig {


    private String smstype;


    private String fromEmail;


    private String subjectEmail;


    private String subjectManual;


    private List<Integer> countries;


    private String redirectUrl;

    public String getSmstype() {
        return smstype;
    }

    public void setSmstype(String smstype) {
        this.smstype = smstype;
    }

    public String getFromEmail() {
        return fromEmail;
    }

    public void setFromEmail(String fromEmail) {
        this.fromEmail = fromEmail;
    }

    public String getSubjectEmail() {
        return subjectEmail;
    }

    public void setSubjectEmail(String subjectEmail) {
        this.subjectEmail = subjectEmail;
    }

    public String getSubjectManual() {
        return subjectManual;
    }

    public void setSubjectManual(String subjectManual) {
        this.subjectManual = subjectManual;
    }

    public List<Integer> getCountries() {
        return countries;
    }

    public void setCountries(List<Integer> countries) {
        this.countries = countries;
    }

    public String getRedirectUrl() {
        return redirectUrl;
    }

    public void setRedirectUrl(String redirectUrl) {
        this.redirectUrl = redirectUrl;
    }
}

Answer 2

首先，请为您的项目添加以下依赖项，并按照Spring Doc说明进行操作＆＃34; 使用注释处理器生成您自己的元数据＆＃34;

http://docs.spring.io/spring-boot/docs/1.5.6.RELEASE/reference/html/configuration-metadata.html#configuration-metadata-annotation-processor

以下是用于生成自定义spring元数据配置属性的maven依赖项

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
    <optional>true</optional>
</dependency>

您的applicationconfig类也应该有getter和setter

@Configuration
@EnableAutoConfiguration
@ConfigurationProperties(prefix = "company.services.verification")
public class ApplicationConfig {

    @NotNull
    String smstype;

    @NotNull
    String fromEmail;

    @NotNull
    String subjectEmail;

    @NotNull
    String subjectManual;

    @NotNull
    List<Integer> countries;

    @NotNull
    String redirectUrl;

    public String getSmstype() {
        return smstype;
    }

    public void setSmstype(String smstype) {
        this.smstype = smstype;
    }

    public String getFromEmail() {
        return fromEmail;
    }

    public void setFromEmail(String fromEmail) {
        this.fromEmail = fromEmail;
    }

    public String getSubjectEmail() {
        return subjectEmail;
    }

    public void setSubjectEmail(String subjectEmail) {
        this.subjectEmail = subjectEmail;
    }

    public String getSubjectManual() {
        return subjectManual;
    }

    public void setSubjectManual(String subjectManual) {
        this.subjectManual = subjectManual;
    }

    public List<Integer> getCountries() {
        return countries;
    }

    public void setCountries(List<Integer> countries) {
        this.countries = countries;
    }

    public String getRedirectUrl() {
        return redirectUrl;
    }

    public void setRedirectUrl(String redirectUrl) {
        this.redirectUrl = redirectUrl;
    }
}

<强> EmailController.class

@Controller
@Produces(MediaType.APPLICATION_JSON)
@RequestMapping(value = "/verify/email")
public class EmailController {

    @Autowired
    private ApplicationConfig config;

    @ResponseBody
    @RequestMapping(method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON)
    public String newRequest(@RequestBody String email) throws
            IOException {

        return email;
    }
}

由于我对您的控制器中的byEmail类没有任何了解，我将其删除。

<强> Application.yaml

company:
  services:
    verification:
      from-email: noreply@company.com
      redirect-url: http://www.google.com
      subject-email: Email Verification
      smstype: Claims
      subject-manual: Claim Initiated
      countries:
        - 1
        - 2
        - 3
        - 4

这是最重要的部分，您还应该将applicationcontext添加到测试类中，并在任何测试之前进行必要的模拟操作。

EmailControllerTests.java

@RunWith(SpringRunner.class)
@AutoConfigureMockMvc
@WebAppConfiguration
@SpringBootTest
public class EmailControllerTests {
    @Autowired
    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext applicationContext;

    @Mock
    private ApplicationConfig applicationConfig;

    @Before
    public void init() throws Exception {
        MockitoAnnotations.initMocks(this);

        // @formatter:off
        this.mockMvc = webAppContextSetup(this.applicationContext)
                .alwaysDo(print())
                .build();
        // @formatter:on

        EmailController emailController = this.applicationContext.getBean(EmailController.class);

        // REPLACE YOUR SERVICES WITH the MOCKED ONES HERE
        //ReflectionTestUtils.setField(emailController, "byEmail", this.byEmail);
        ReflectionTestUtils.setField(emailController, "config", this.applicationConfig);
    }

    @Test
    public void unauthenticatedUsersCannotAddProperty() throws Exception {
        // @formatter:off
        MvcResult result = this.mockMvc.perform(post("/verify/email").contentType(MediaType.APPLICATION_JSON).content("{ahmet@ahmet.com}"))
                .andDo(print())
            .andExpect(status().isOk())
            .andReturn();
        // @formatter:on

        Assert.assertNotNull(result);
    }
}

结果就是这样，一切都在按原样运作......

希望这会有所帮助......
