Question

我正在使用最新版本的spring-boot，并尝试按照here

所述向我的json实体添加id

如果我添加此配置，我的JSON响应将不再起作用：

2015-03-02 11:55:13.949 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Looking up handler method for path /hal/tutorials/1 2015-03-02 11:55:13.951 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Did not find handler method for [/hal/tutorials/1] 2015-03-02 11:55:13.974 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Looking up handler method for path /error 2015-03-02 11:55:13.975 DEBUG 8288 --- [nio-8080-exec-1] o.s.b.a.e.mvc.EndpointHandlerMapping : Did not find handler method for [/error]

这是我的主要配置文件，我尝试将RepositoryConfig移动到它自己的文件中并使用@Component而不是@Configuration，但没有任何作用。

@SpringBootApplication
@EntityScan(basePackages = { "com.mypp.domain" })
@EnableJpaRepositories(basePackages = { "com.mypp.repository" })
@EnableTransactionManagement
@EnableGlobalMethodSecurity
@EnableJpaAuditing
@EnableConfigurationProperties
public class ShelltorialsApplication {

    public static void main(String[] args) {
        SpringApplication.run(ShelltorialsApplication.class, args);
    }
}




    @Configuration
    public class RepositoryConfig extends
            RepositoryRestMvcConfiguration {

        @Override
        protected void configureRepositoryRestConfiguration(
                RepositoryRestConfiguration config) {
            config.exposeIdsFor(Tutorial.class);
        }
    }

我做错了什么？

我的工作正常，我需要延长SpringBootRepositoryRestMvcConfiguration而不是RepositoryRestMvcConfiguration

@Configuration
public class RepositoryConfig extends
        SpringBootRepositoryRestMvcConfiguration {

    @Override
    protected void configureRepositoryRestConfiguration(
            RepositoryRestConfiguration config) {
        config.exposeIdsFor(Tutorial.class);
    }
}

如果您希望所有jpa实体公开其id值，您可以执行以下操作

添加此依赖项：

<dependency>
    <groupId>org.reflections</groupId>
    <artifactId>reflections-maven</artifactId>
    <version>0.9.9-RC2</version>
</dependency>

并按如下方式修改配置。

@Configuration
public class RepositoryConfig extends SpringBootRepositoryRestMvcConfiguration {

    @Override
    protected void configureRepositoryRestConfiguration(RepositoryRestConfiguration config) {

        //change com.yourpackage.domain to point to your domain classes
        Reflections reflections = new Reflections("com.yourpackage.domain");
        Set<Class<?>> entities = reflections.getTypesAnnotatedWith(Entity.class, false);

        config..exposeIdsFor(entities.toArray(new Class[entities.size()]));
    }
}

如何覆盖类
