java - 无法使用 Spring Boot 找到 Spring Data Rest 端点

Question

我是第一次尝试 Spring Data Rest，但我似乎无法在 localhost:8080/books 找到我的存储库端点 有人看到我配置错误了吗？

应用类

@SpringBootApplication
@ComponentScan(basePackageClasses = {Book.class})
public class SpringDataMicroServiceApplication {

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

图书实体

@lombok.Getter
@lombok.Setter
@lombok.RequiredArgsConstructor
@lombok.EqualsAndHashCode(of = "isbn")
@lombok.ToString(exclude="id")
@Entity
public class Book implements Serializable {

    @Id
    @GeneratedValue(strategy= GenerationType.AUTO)
    private long id;

    private String isbn;

    private String title;

    private String author;

    private String description;
}

图书资料库

public interface BookRepository extends CrudRepository<Book, Long> {
}

Gradle 构建文件

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'io.spring.gradle:dependency-management-plugin:0.5.4.RELEASE'
    }
}

apply plugin: 'io.spring.dependency-management'
apply plugin: 'java'
apply plugin: 'idea'

dependencyManagement {
    imports {
        mavenBom 'io.spring.platform:platform-bom:2.0.5.RELEASE'
    }
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-aop')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.data:spring-data-rest-hal-browser')
    compile('org.projectlombok:lombok:1.16.6')
    compile('org.springframework.retry:spring-retry')
    compile('org.springframework.boot:spring-boot-starter-validation')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.boot:spring-boot-starter-ws')
    compile('org.springframework.boot:spring-boot-actuator')

    runtime('com.h2database:h2')

    testCompile('org.springframework.boot:spring-boot-starter-test') 
    testCompile('org.springframework.restdocs:spring-restdocs-mockmvc')
}

在 spring boot 中，默认情况下您不需要执行 @ComponentScan 、 @EntityScan 和 @EnableJpaRepositories 。将 @RepositoryRestResource 添加到您的存储库。从入门类中删除除 @SpringBootApplication 之外的所有注释。 Spring boot 默认会扫描所有包。然后您将能够找到端点 localhost:8080/books。它对您不起作用，因为您专门只扫描实体类。未扫描存储库。当您删除这些注释时，将扫描所有包并创建存储库 bean，并且端点将可用。

如果您使用多个包，请确保将您的应用程序启动器保留在基础包中。示例:

src
    main
        java
            com.myapp.springstuff
                Application.java
                package1
                package2
