spring - 如何配置 Spring Data REST 以将新创建​​的实体作为 POST 正文的一部分返回

Question

我正在使用 Spring Data REST 将我的 JPA 存储库公开为 Web 服务。

我正在使用 RestTemplate 测试这些 Web 服务中的每一个。我希望这些测试是集成测试……这意味着我在我的应用程序运行时执行每个测试。我不想 mock 任何东西。

现在我想知道的是如何配置 Spring Data REST 以在发送 HTTP POST 时将新创建的实体作为正文的一部分返回。

我尝试在配置类 RepositoryRestMvcConfiguration 中设置适当的标志，但它似乎不起作用。

这是我的配置类:

@Configuration
public class RepositoryRestMvcConfiguration extends org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration {

    @Override
    public RepositoryRestConfiguration config() {
        RepositoryRestConfiguration config = super.config();
        config.setBasePath("/sdr-api");                
        config.setReturnBodyOnCreate(Boolean.TRUE);
        config.setReturnBodyOnUpdate(Boolean.TRUE);        
        config.exposeIdsFor(Project.class);        
        config.setDefaultMediaType(MediaType.APPLICATION_JSON);        
        return config;
    }
}

这是我希望能够执行的测试示例:

@Test
@SqlGroup({ @Sql(scripts = "/clear-data.sql", config = @SqlConfig(transactionMode = TransactionMode.ISOLATED)) })
public void create() {
    final String PROJECT_NAME = "MY_PROJECT";

    Project project = new Project();
    project.setName(PROJECT_NAME);

    ResponseEntity<Project> response = restTemplate().postForEntity(getBaseUrl() + "projects", project, Project.class);
    assertThat(response.getStatusCode(), equalTo(HttpStatus.CREATED));

    Project projectCreated = response.getBody();
    assertThat(projectCreated.getId(), notNullValue());
    assertThat(projectCreated.getCreatedBy(), notNullValue());
    assertThat(projectCreated.getCreatedDate(), notNullValue());
    assertThat(projectCreated.getLastModifiedBy(), notNullValue());
    assertThat(projectCreated.getLastModifiedDate(), notNullValue());
    assertThat(projectCreated.getName(), equalTo(PROJECT_NAME));
}

此测试在以下语句上失败，因为 ID 以及所有其他属性为 null...

assertThat(projectCreated.getId(), notNullValue());

即使我尝试使用 curl 调用 WS，它也没有给出我期望的结果...

curl -i -X POST -H "Content-Type:application/json" -d '{ "name" : "MY_PROJECT" }' http://localhost:8081/myproject/sdr-api/projects

它应该返回新创建的实体，它应该返回结果作为 application/json 而不是我的配置类中指定的 application/hal+json...

{
  "_links" : {
    "self" : {
      "href" : "http://localhost:8081/myproject/sdr-api/projects/4"
    },
    "project" : {
      "href" : "http://localhost:8081/myproject/sdr-api/projects/4{?projection}",
      "templated" : true
    }
  }
}

知道问题出在哪里吗？

在过去的几个小时里，我尝试了很多事情......在 Spring 2.4.0.RELEASE 中，我尝试按照

的建议使用 RepositoryRestConfigurerAdapter

@Configuration
@Import(RepositoryRestMvcConfiguration.class)
public class SpringDataRestConfiguration extends RepositoryRestConfigurerAdapter {

    @Override
    public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
        config.setBasePath("/sdr-api");
        config.setReturnBodyOnCreate(Boolean.TRUE);
        config.setReturnBodyOnUpdate(Boolean.TRUE);
        config.exposeIdsFor(Project.class);
        config.useHalAsDefaultJsonMediaType(false);
        config.setDefaultMediaType(MediaType.APPLICATION_JSON);
    }
}

但我仍然得到相同的结果...虽然我的 SDR API 在/sdr-api 下可用，但代码似乎已执行。

所以我决定将 Spring Data Rest 的版本降级到 2.3.2.RELEASE。我以这种方式修改了我的配置类:

@Configuration
public class MySDRConfiguration extends RepositoryRestMvcConfiguration {

    @Override
    public void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {
        config.setBasePath("/sdr-api");
        config.setReturnBodyOnCreate(Boolean.TRUE);
        config.setReturnBodyOnUpdate(Boolean.TRUE);
        config.exposeIdsFor(Project.class);
        config.useHalAsDefaultJsonMediaType(false);
        config.setDefaultMediaType(MediaType.APPLICATION_JSON);
    }
}

这次，它成功了!我得到的结果是我所期待的:

HTTP/1.1 201 Created
Server: Apache-Coyote/1.1
Access-Control-Allow-Methods: GET, POST, HEAD, PUT, DELETE, OPTIONS
Access-Control-Max-Age: 3600

  "createdDate" : "2015-11-12T20:55:32.368Z",
  "lastModifiedBy" : "anonymousUser",
  "lastModifiedDate" : "2015-11-12T20:55:32.368Z",
  "name" : "TEST",
  "links" : [ ],
  "content" : [ ],
  "links" : [ {
    "rel" : "self",
    "href" : "http://localhost:8081/myproject/sdr-api/projects/3"
  }, {
    "rel" : "testPlans",
    "href" : "http://localhost:8081/myproject/sdr-api/projects/3/testPlans"
  } ]
}

我是否遗漏了最新版本的 Spring Data REST？

Spring :

<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.5</version>

@SpringBootApplication
public class QuizApplication implements ViewProvider {
    public static void main(String[] args) {
        SpringApplication.run(QuizApplication.class, args);
    }

    @Bean
    public RepositoryRestConfigurer repositoryRestConfigurer(EntityManager entityManager) {
        return RepositoryRestConfigurer.withConfig(config -> config.exposeIdsFor(Question.class));
    }
}
