SpringFox，带有 JpaRepository 的 Spring Data Rest - Swagger 无法识别带有 Spring Boot 的 Rest 存储库

Question

我的 API 文档在使用 Springfox swagger 2 时遇到了问题。它无法识别我的其余存储库 (JpaRepository/PagingAndSortingRepository)。

import org.springframework.data.jpa.repository.JpaRepository;

import com.aegon.dop.model.Book;

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

即使我尝试添加像下面这样的大摇大摆的注释，但没有运气

@Api(tags = "books")
@RepositoryRestResource(collectionResourceRel = "books", path = "books")
public interface BookRepository extends JpaRepository<Book, String> {
    @ApiOperation("Find all books by book name")
    Dopadviseur findByBookName(@Param("bookName") @RequestParam @ApiParam(value = "bookName") String bookName);
}

然而，HAL 浏览器可以识别我的其余存储库。有人可以帮我弄这个吗。 这是我的 pom 依赖项，

这是我的引导类，

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Import;

import springfox.documentation.spring.data.rest.configuration.SpringDataRestConfiguration;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@SpringBootApplication
@EnableSwagger2
@Import({ SpringDataRestConfiguration.class })
public class DopApplication {
    public static void main(String[] args) {
        SpringApplication.run(DopApplication.class, args);
    }
}

当我添加 @Import({ SpringDataRestConfiguration.class }) 时，应用程序启动时出现以下错误

   Caused by: java.lang.NoSuchMethodError: org.springframework.data.repository.support.Repositories.getRepositoryInformationFor(Ljava/lang/Class;)Lorg/springframework/data/repository/core/RepositoryInformation;

Answer 1

简介

我认为您需要在代码中包含以下内容：

@Import({springfox.documentation.spring.data.rest.configuration.SpringDataRestConfiguration.class})

查看以下讨论您的问题的线程：

https://github.com/springfox/springfox/issues/699#issuecomment-270052170

来自 Github 的完整建议答案：

@SpringBootApplication @EnableSwagger2 @Import({springfox.documentation.spring.data.rest.configuration.SpringDataRestConfiguration.class}) public class ServletInitializer extends SpringBootServletInitializer {

更新

我认为你应该升级到：

春狐 2.9.0 : https://github.com/springfox/springfox/issues/2372 他们提到了一个与您的问题非常相似的问题，该版本已解决。
